A Catadioptric telescope is a type of telescope that uses both lenses and mirrors to capture an image. This makes them more compact and lightweight than a traditional telescope. There are several advantages to using a Catadioptric telescope. They have a wider field of view than a traditional telescope, and they can be used for both terrestrial and astronomical observations. They are also less expensive than a traditional telescope. The disadvantages of Catadioptric telescopes include the fact that they are more difficult to align than a traditional telescope, and they may produce a distorted image.
There are a few things to consider when choosing a catadioptric telescope. The first is the size of the telescope. The larger the telescope, the more light it can gather and the more detail you will be able to see. The second is the price. Catadioptric telescopes can be quite expensive, so be sure to do your research and find one within your budget. The third is the type of catadioptric telescope. There are two main types: Schmidt-Cassegrain and Maksutov-Cassegrain. Each has its own advantages and disadvantages,
There is no easy answer when it comes to choosing between a Cassegrain and reflector telescope. Both have their own unique set of benefits and drawbacks that must be considered. In general, Cassegrains are better suited for long-range viewing, while reflectors tend to be more portable and easier to set up. Ultimately, the best choice for you will depend on your individual needs and preferences.
The Cassegrain telescope is a type of reflective telescope that uses a concave secondary mirror in order to reflect light back through a hole in the primary mirror. This design is often used in large telescopes because it allows for a longer focal length than what is possible with a refractor telescope of the same size. One advantage of the Cassegrain design is that it eliminates chromatic aberration. This is because the light is only reflected once, instead of twice like it is in a Newtonian telescope. This means that the image will be sharper and clearer. Another

No regrets with purchases here! I chose this telescope after spending several days researching the best one to buy as my first telescope. I tend to think in terms of going big or going home, so I decided that a $800 huge scope with gps would be preferable than a $200 tiny table top scope that I wouldn't use and would make me give up. I'm glad I didn't follow my first instinct on this one!I couldn't be happier with this scope, which is of fantastic quality. As many have noted, the compact shape is incredibly convenient and encourages use more so than a large telescope. It is absolutely untrue to assume that because this telescope is small and portable, it will deliver inexpensive photos. I recently purchased a 2x Barlow, and I believe it perfectly caps off this scope. With the exception of the 10mm with the Barlow, the extra magnification is still of excellent quality. The fact that the scope is so small and light helps it move around less in the wind is another benefit! I didn't consider the size of the scope or the wind because I reside in west Texas, but I soon discovered that I had made the proper choice because I could easily see the night sky on a typical windy night.You could ask, as I did, what can you see with this scope. You can clearly see Jupiter and all four of its moons using the provided 25 mm and 10 mm lenses. The cloud bands are very obvious, and occasionally I can see the infamous red storm, however even with Barlow 2x it just appears as a little speck. It is also simple to see Saturn and its ring, but don't look for the Cassini Division in the ring—if you do, it will be quite faint. With the Barlow 2x, you can easily focus on a few craters on the moon, which is spectacular and simple to view. Although I was happy with my purchase, the changeable moon filter is not necessary for a superb moon view. I've tried to look at Mars and Venus, but thus far they appear more as a brilliant off-colored speck with little to no details and, to be honest, kind of dull. I have only tried a few times in a town location with street lights close to my house, so I'm unsure how well nebulas materialize in this scope. Orion's Nebula appears more like a little light cloud or bright region, as far as I can tell.The swivel stand is cheap, and some people complained about it. I can understand why some people could think it is rather inexpensive, but I don't believe it to be of poor quality or a poor stand. Don't let the negative evaluations deter you from taking what seems to be the right position that will last.The only thing that irritates me a little is trying to track the items as they rise or fall out of my line of vision. It can seem a little jerky to move the telescope up and down and toss the image around, according to someone or a few others. That's accurate. A portion of this issue can be resolved by releasing the bolt holding the scope to the stand, but given the bolt-on design, it's quite easy to have the scope too loose where it slips down or too tight and jerky. I'm not sure if there is a perfect happy medium. Overall, it's still quite functional, and I'm happy. The best solution would probably be to purchase an equatorial mount, which I have thought about doing. It is unrealistic to expect a bolt-on system, like the one that comes with this stand, to spin an equitorial mount mechanically without any issues. However, the current design still works admirably, and I consider it to be quite usable.I was unsure if I would be able to find and bring the needed object inside the scope's range of view before buying this scope. I had strong urges to purchase a "go to" or GPS scope. I'm relieved I didn't throw my money away! Finding objects is made incredibly ez (ha ha) using the Ez Finder II. In addition, I learned that the iPhone has a number of inexpensive or free apps you can download that let you simply hold your phone up to the night sky to find objects or even at your feet to see what stars or objects are on the opposite side of the earth! Excellent apps that remove the burden of having to know what is what to get a head start in astronomy.I've included a photo that I attempted to take while holding my iPhone up to the eyepiece. Because this was so challenging, I haven't yet been able to capture a clear image of Jupiter. I think this photo was captured using a variable moon filter, a 10mm lens, and a barlow 2x.

This telescope is excellent. Don't let YouTube videos or other reviews try to persuade you to choose the 5 "The 8" gathers about 78% more light than the 6SE model, which is smaller and more portable. Light gathering ability is EVERYTHING in a telescope.However, there are at least two accessories that you MUST have right out of the box, so you won't be dissatisfied:1) A power source for the telescope, such as an AC adapter, Celestron "PowerTank," or a car or motorcycle battery with a vehicle converter wire. The Celestron Power Tank 17 is what I own. If you want to monitor remotely next to your car and you buy the car adaptor, the power tank uses cigarette lighter-style power cords that you can also plug into your car's dashboard. Although AA batteries can power the scope, they will be used in less than an hour, making the scope slow and finally useless.2) Purchase a dew shield (Celestron #940009 for 8" scopes), which costs around $23.00 and prevents night dew from condensing on the telescope's "corrector."

You can get 20 MM and 8 MM views with the aforementioned Barlow adaptor.Explore Scientific's 82° 30MM eyepiece is the second eyepiece. On order to utilize it, you will need to modify your telescope by adding a longer dove-tail rail and moving the scope further forward in the mount to balance it. ADM V Series Extra Long is what I use (VC-8XL). To make the aft mount bracket fit on this telescope, I had to cut it. You get 30 and 15 MM views with the 2.5 Barlow.Although Celestron Luminos eyepieces are available, some astronomers find their occasional EOFB (Edge Of Field Brightness) bothersome. Buy the 19MM and 23MM if you decide to use Luminos. They are not as good as the other two I suggested, albeit I do possess those two.If you didn't know, a smaller MM eyepiece in a telescope allows for more zooming (greater magnification). To calculate zoom, divide the eyepiece mm by the focal length of the scope (2032MM for the Nexstar 8SE).

Excellent telescope for three years. For the polar alignment feature, I purchased the 5". There are already a lot of positive evaluations of the scope here. Therefore, I'll just state that you need a good camera and a computer to convert your photos into beautiful images and that you can't actually "see" what these images depict. Additionally, I would advise purchasing the Celestron Star Sense Auto Align because it will allow for greater viewing time while saving time.

Once more, the scope only comes with a single 25MM 1.25" eyepiece out of the box "eyepiece, which has a little field of view and insufficient magnification to really appreciate your first amazing astronomical sights, such as staring at Saturn and observing the gaps in the rings.A kit offered by Celestron includes a diagonal, two 2X Barlow Lenses, and three "(Kit #94305; $300) eyepieces You can purchase that to get started with 2 "eyepieces for the cheapest price.Instead of purchasing the 2" starter kit, I would advise purchasing the Celestron 93527 2" diagonal, which has Starbright XLT coatings and can be used with both the 2" and the 1.25" eyepiece that is included with the telescope, as well as the Celestron Luminos 2.5X Barlow lens (#93436), which will enable you to more than double your magnification with any eyepiece. If you have the financial means to "do it all right the first time"Most people will advise you to start out with no more than three eyepieces. Here are a few suggestions:Buy TeleVue if money is no object. They represent the pinnacle of telescope technology. Depending on what you choose, between $300 and $800 per item. If you're going to spend that much money, join the CloudyNights community to acquire recommendations from other TeleVue customers that are specifically targeted to your needs.I'm going to stay with trusted, high-quality, less expensive things that are still good.Here on Amazon, you can purchase the Meade Instruments Ultra Wide Angle 20mm 2-Inch Waterproof Eyepiece (7743) for about $120. You can get 20 MM and 8 MM views with the aforementioned Barlow adaptor.Explore Scientific's 82° 30MM eyepiece is the second eyepiece. On order to utilize it, you will need to modify your telescope by adding a longer dove-tail rail and moving the scope further forward in the mount to balance it. ADM V Series Extra Long is what I use (VC-8XL). To make the aft mount bracket fit on this telescope, I had to cut it. You get 30 and 15 MM views with the 2.5 Barlow.Although Celestron Luminos eyepieces are available, some astronomers find their occasional EOFB (Edge Of Field Brightness) bothersome. Buy the 19MM and 23MM if you decide to use Luminos. They are not as good as the other two I suggested, albeit I do possess those two.If you didn't know, a smaller MM eyepiece in a telescope allows for more zooming (greater magnification). To calculate zoom, divide the eyepiece mm by the focal length of the scope (2032MM for the Nexstar 8SE). For instance, 2032/19 = 107x. If you decide to upgrade to a larger Celestron telescope in the future, you can utilize the diagonal and eyepieces I've suggested (I have a Celestron C11 on a CG5-ASGT mount as well).This scope aligns effortlessly by pointing to three bright objects in the sky, is ideal for a beginner, and can be put up in about 10 minutes. The ideal "grab-and-go" telescope, it. Because it is an Altitude/Azimuth (ALT/AZ) telescope and BOTH motors must operate at once to follow an object, it is NOT suited for astro-photography. This makes it less accurate than a German Equatorial Mount (GEM), where only one motor needs run to track an object. Polar alignment is necessary for GEMs, which is a little challenging for a beginning.The CPC Deluxe 925HD (9.25") or CPC 1100 series (11") are the next steps up from the 8SE if a larger, more user-friendly ALT/AZ scope is desired. If you get interested in astronomy and astro-photography, you may also upgrade to a GEM telescope.4 stars because it comes without an AC converter or a DC cigarette lighter cord. I would rate it 5 with those things!beginning telescope at an excellent price. To be truly entertaining, it needs an AC, cigarette lighter, or power tank converter, as well as upgraded eyepieces.

I'm pleased with this telescope and mount so far. It is about the size I would desire in a grab-and-go telescope. Any larger, and gathering and setting up the necessary equipment would become a production. I can easily carry this entire arrangement through the house with one hand because it is rather lightweight. It took two days for it to arrive after I used the free shipping. After placing my order, I saw a similar setup on Amazon for $50 cheaper without the star maps, and you can purchase the star maps for less than $30. I didn't need the maps, so that was quite frustrating. The Wi-Fi on the scope looks to be reasonably robust. My initial try worked, but I took my time meticulously centering the stars. The tracking and go-to seemed effective. Every item I chose was always present in my eyepiece, if not in the exact center. The focuser, which is rather inexpensive and produces a lot of shaking when trying to focus, and some lag when manually manipulating the telescope through the tablet, although those problems only arise when aligning at the start of the session. The telescope should have a mechanical option to regulate movement. I am pleased with my purchase and would advise others to do the same.

I apologize for the lengthy review, but I believed the information could be useful to those considering this amazing small device.Last week, my Celestron StarSense was delivered, and I've had a few opportunities to use it since then. Although I've only used the device twice, I believe my observations could be helpful to others who are considering buying it.Alignment is a common hassle for me because I specialize in astrophotography and my setup is entirely portable on a tripod. Because I had read that it had significant problems merging with Celestron's native polar alignment procedure, ASPA, I postponed purchasing the gadget (All-Star Polar Alignment). I decided to purchase it when Celestron fixed those problems and I read a favorable review of the product in Sky and Telescope. I am delighted I did so far.I promptly updated the firmware on the StarSense camera and the supplied hand controller after opening the box. As I noted, Celestron has made significant software updates since the gadget was first released, so you'll want to be sure to record these. Make sure you are prepared for this with the necessary cables and adapters.After updating the firmware, I fastened the SS camera to my scope. I have a Celestron Advanced VX mount but a non-Celestron OTA. This was one thing that bothered me about Celestron. They offer two mounting options: one that is very secure for Celestron OTAs and one that is less secure for all other OTAs. It irritated me that, merely because Celestron had manufactured the mounting holes too small, I couldn't use the more reliable way of attachment on a dovetail plate. People would have had a lot more alternatives if they had just offered a few holes in the typical mounting sizes. Since Celestron does not include a mounting base with the unit (they assume you will be replacing your finderscope with the SS camera), I was relieved to have an extra mounting base on hand. I gave up my mounted laser pointer in order to move on with the SS camera. You will need to wait for Amazon to deliver the item if you just have one finderguider and no additional mounting base when the unit arrives.I turned on the mount with the new HC and SS camera installed after getting situated outside and performing a rough polar alignment with a polar scope. The HC starts by looking for the SS camera, which it does without any issues.The HC can be a little "bossy" at beginning because there doesn't appear to be a way to start up without first performing the SSA (StarSense AutoAlign) process. The DateTime and location that I usually enter at starting didn't appear to be an option. I didn't realize it at the time, but you may add those data by using the Menu button.I relinquished control to the SSA, which slewed to four separate areas of the sky. I was in my side yard, where the house and trees largely obscured the horizon and there was a lot of light pollution. In order to add to the intrigue, I had also forgotten to turn off a powerful flood light that was attached to my roof. I got going rather early, and I could only make out about five to ten stars. I saw that the HC was claiming to have discovered numerous stars in regions of the sky when I was still unable to detect any.The SSA completed its work and declared success after a short while. Since it had been so quick and simple, I was now 90% positive that the device hadn't actually done anything. I directed the HC to locate Albireo. It was there, off center but within my 20mm eyepiece's field of view. Very good. I instructed it to look for Antares down south. That was it. Whoa.At this point, Celestron instructs you to carry out a centering technique in order to correct the discrepancy between your telescope and the SS camera. This can be done using the HC's software and does not require physically moving the camera, which was a relief because I believe I have experienced enough of the "dance of the thumbscrews" to last a lifetime. Centering the star in your eyepiece and then verifying that it is centered with the HC are the steps that the HC recommends for this. This was quite straightforward, but the printed instruction booklet contains a typo regarding the process's steps. If you purchase this item, it's a good idea to merely download the (updated) online handbook.The HC informs you that you must repeat the SSA process after the centering procedure. It wasn't entirely obvious at this point if it wanted me to restart the entire process or to actually reset my mount to the alignment marks and start anew. Thankfully, the first appeared to function perfectly.I completed all of this before to entering the time, date, or place. Moving on to polar alignment without entering that information initially felt incorrect, but is it really necessary if the HC already knows the positions of all the stars, especially if you aren't aiming at solar system objects? I had to search through the menus to even locate where to enter the date imelocation because I was never asked for it by the HC, who didn't appear to be concerned. After entering the data, the HC instructed me to repeat the SSA, which I did.Polar alignment was an easy operation. Typically, ASPA consists of two steps: the first asks you to center a star using the HC's direction buttons, and the second instructs you to do the same using the mount's ALT and AZ alignment knobs. The user just needs to make the ALT and AZ changes while using SSA because the first step is completed automatically.Any stars or objects I chose were precisely centered in the reticle eyepiece after centering calibration and ASPA. I spent some time choosing items close to the compass' four points and was astonished when they all came up dead center. I began directing and took some test pictures with the CCD; for 12 minute exposures, I obtained flawless pinpoint stars. The Pelican Nebula was the subject of 14 12-minute exposures I made that night, and I captured some of the sharpest, roundest stars I've ever photographed. To cut a long tale short, ASPA was incredibly simple and precise.I was simply performing a rough alignment on the second night out in order to use my larger scope to snap images of the moon. I merely removed the gadget from my refractor and mounted it on my SCT, mounted the OTA, connected it, turned it on, and waited for it to align. That night, when just a few stars were visible to these middle-aged eyes, I began even earlier. No polar alignment, no date or location entry, no re-centering or fine-tuning. After a few minutes, the SSA was complete, and the GOTO successfully placed the moon into my 20mm eyepiece's field of view (FOV) on the first try with a 10" SCT. The FOV was less than a moon-width. Despite using a different OTA and skipping a new centering calibration procedure, I also tried a few stars, and they were all rather close to the center.The bottom line: On its first two nights of use, this device exceeded expectations. If you have a portable setup, I'd say making this purchase is a no-brainer.Pros: Simpler ASPA; easier telescope alignment; easier setup (aside from the firmware upgrade); more precise polar alignment (at least in my experience). works at dusk, allowing you to begin your alignment earlier. works despite a significant portion of the sky being blocked by trees or buildings. Fast.Cons: Mounting bracket performance falls short of expectations (see above). There is no base for the finder mount. The default display on the new HC is small-print, which might be challenging to read, especially at a distance.

IMPORTANT! Jupiter won't appear as big as it does in the "vanilla" FirstScope images. Unlike the Celestron FirstScope, which has eyepieces with astronomers' names on them, this Cometron variant has various eyepieces (the "vanilla" FirstScope). The 20mm and 10mm eyepieces of the Cometron version provide 15x and 30x magnification, respectively. With 20mm and 4mm eyepieces, the "vanilla" version provides 15x and 75x magnification. With the Cometron version, Jupiter and its moons are still visible, but they appear as stars.This scope is a fantastic tool, despite the absence of severe magnification (which, to be honest, will look hazy with such a small scope). Since it arrived (about three weeks ago), I've used it every clear night, and I've never been let down. As a manual finder scope rather than an electronic red dot scope, the accompanying finder scope requires some work to properly zero in, but it eventually functions nicely. Observing the moon and star clusters that are hidden from human vision are both amazing. Although I haven't yet visited a dark sky region, I have no doubt that this scope will continue to astound me.

This evaluation is for the 9.25"With this telescope, I'm really amazed. I made an upgrade from an 8" and saw a big improvement.The telescope is delivered in various sections (tripod, mount, and OTA), however assembling it only only a few minutes.The tripod is incredibly stable and strong. It can also be shut without the spreader being taken out. On one of the legs, there is a strap that can be used to secure the tripod during transit. Since the spreader is made of metal rather than plastic, it is sturdy and practical for storing eyepieces.The mount is sturdy and somewhat heavy, and a spring-loaded knob holds it to the tripod. a development over the 8.Once everything is put together, I can still move it without disassembling it, even if only a little distance (from inside the house to the backyard where I do the observation). I have to separate and fold the tripod from the rest if I'm going somewhere by car.The alignment is made simpler by the mobile device's WiFi connection. You can only point at three stars because the scope uses the mobile device's GPS to determine your location and the current time. Much quicker compared to my old Nerxstar 8SE, which required you to punch in your location, city, time zone, etc.However, I would have preferred more stability with the mobile app. The software frequently freezes, occasionally loses connection to the scope, is unresponsive, or you simply tap on a movement arrow and the scope continues to move because the program is stuck and believes you are still pushing the moving button. When fine aligning objects, the sluggish response frequently causes you to overcorrect. In fact, I currently use the app for GoTo alignment setup, but I utilize a handheld device for all scope movement, fine tuning, and corrections to prevent overcorrections and annoyance app responsiveness. The app needs to be significantly improved.The finderscope is identical to the 8SE's and falls short of the upgraded instrument. does the job, however the red light is a little too strong and the finderscope's collimation is challenging and unstable. In a nutshell, the finderscope is affordable and suitable for lower tier scopes. Celestron ought to be offering a better alternative.Also missing from the Evo 9.25 is the RS232 cable needed for firmware upgrades. Seriously? a $2000 scope without the required $5 cable I'm not sure which poor marketing choice that is. With my previous 8SE, which cost half as much, the cable was already included. Initially, I thought it was because firmware updates could be made using WiFi, however that isn't the case.Another difference I've seen between this scope and the 8SE is how frequently—almost always—I need to collimate the optic. It arrived extremely out of collimation and, perhaps as a result of the larger optics, doesn't appear to maintain collimation after moving.Additionally more severe than the 8SE is chromatic aberration.Compared to the 8SE, the motor is far better, considerably more precise, accurate, and effective, and it preserves alignment lot better. However, it is also significantly noisier.A beneficial addition is the red light that is projected onto the mount where there is room for an eyepiece.NOTE: Purchase the Vibration Suppression Pads ASIN B0000665V7 as well. They genuinely make a difference, drastically lowering wind-induced vibration or vibration caused by you concentrating on an object. When you stop touching anything, the vibrations stop quickly, unlike when there are no pads, where it takes a few extra seconds.The scope was purchased through Adorama (ASIN B0172UR7QU), which is the same and includes a free eyepieces kit. The packaging, shipping, and interactions I had with their customer assistance were all excellent, and I was very delighted with all of these things.In conclusion, it has a large enough aperture to take extremely good observations and photographs even in a city's smog-filled light, while still being small enough to be packed and moved around with ease. In comparison to the Nexstar 8SE, it includes a number of features and improvements, including a much more durable tripod, a better motor, wifi that enables you to use a mobile device's GPS, and more.See the images below, which were captured with an Evo 9.25 and a Neximage 5 and edited with PIPP and Registax 6.
There are four main types of telescope – refracting, reflecting, catadioptric, and radio. Refracting telescopes use lenses to focus light, while reflecting telescopes use mirrors. Catadioptric telescopes combine both lenses and mirrors, while radio telescopes detect electromagnetic radiation instead of visible light.
A catadioptric telescope is a type of telescope that uses both mirrors and lenses to gather light and form an image. This design offers several advantages over traditional telescopes, such as a wider field of view and a shorter overall length. One of the most popular types of catadioptric telescope is the Schmidt-Cassegrain telescope. This design uses a mirror at the back of the telescope to reflect light back up through a hole in the center of the main lens. This arrangement allows the telescope to be much shorter than a traditional reflector telescope while still gathering a large amount
A good quality telescope can cost anywhere from a few hundred to a few thousand dollars. The price depends on the size, quality, and features of the telescope. Some telescopes come with special features like computerized controls and tracking, which can add to the cost. Generally, the larger and more powerful the telescope, the higher the cost.
A catadioptric telescope is a telescope that uses a combination of lenses and mirrors to gather light and produce an image. The advantage of this type of telescope is that it is compact and can be used for a variety of tasks, including astronomical observing and terrestrial (land-based) viewing.
There are many good telescopes to see Jupiter, but one of the best is the Meade LX200-ACF 16-Inch f/10 Telescope. This telescope has a large aperture and a long focal length, which makes it ideal for viewing Jupiter and its moons. The Meade LX200-ACF 16-Inch f/10 Telescope also has a very good tracking system, which is important for keeping Jupiter in your field of view.
