Telescope Types

While all telescopes are beneficial and operate in a similar way, there are actually various types of them that you can choose from out there and usually, each type also carries different advantages and disadvantages. In general all of them will be able to magnify your object depending on their specification. Just like everything else, it is better to know at least a little bit about your telescope before buying one to make sure the product will perform best in our application.

  • Refractor Telescope

Refractor is the original design of a telescope and the first that can bring a person closer to an object after the invention of magnifying glass itself. Refractor is the stereotype, the most common idea appears in many people’s mind especially those who are not interested in the device when you mention a telescope. This design uses a glass lens at the front of the telescope and when you aim it, the light captured is bent or refracted as it passes through the lens, hence the name.

The advantage is being closed design makes it rarely need maintenance and since the lens is in fixed position, they are generally more rugged. The disadvantage is color aberration which produces a rainbow of colors around the image.

  • Reflector Telescope

After Hans Lippershey made what we called a refractor, not long after, Isaac Newton made a similar telescope but now it uses a mirror to gather and focus light. The design is different and since all celestial objects out there give parallel rays, the reflector telescope’s mirror has a parabolic shape because this shape focuses the parallel light rays to a single point. Its biggest advantage is there is no color aberration but it will require meticulous handling and more maintenance due to the moving parts.

  • Catadioptric Telescope

This is a fairly new compared to the former two and what’s unique about it is that they used both refractor and reflector component which mean they have mirror and lens to produces certain advantages in performance as well as in the manufacturing process. Nowadays, there are two popular Catadioptric styles called Schmidt-Cassegrain and Maksutov-Cassegrain which use mirrors to produce image-like reflector but are a completely different design than their predecessor. 

What’s similar is they have a primary mirror at the end of the optical tube and convex secondary mirror at the front. What’s different is now the primary mirror has a hole in it and the convex secondary mirror has a flat position to the primary. Between Schmidt and Maksutov, the difference is on the corrector plate as Schmidt uses an aspheric lens while Maksutov has a meniscus corrector or highly curved spherical lens.

About Celestron CPC 1100 and NeXstar 8SE

You can pick any model depending on which seems to fit your application or preference the most and in general, the quality of the telescope is decided by the aperture and material quality as similar models don’t always perform the same. The easiest method to shop is based on what you want to observe because the bigger the aperture the brighter the telescope and making them especially useful in deep space observation such as the dobsonian Zhumell Z10 Vs Orion XT10.

If you are looking for a more convenient way of observing and are willing to spend more, a computerized telescope will be a very ideal option to consider. These advanced devices will cut so many aiming and aligning processes that we have to do with manual telescopes and almost any big brands today have the technology ready for your products including Celestron with their huge range of models. We like this brand for the product quality and in most cases you will find almost any types here from affordable to expensive devices. 

For those who are more serious in the game and want to have a device that can last for a very long time, offering good experience, then Celestron CPC 1100 and NeXstar 8SE will be two attractive models to consider. They are nowhere near beginner friendly, not because of the confusing mechanism but because of the fairly high price tag. NexStar SE line is one of the most popular cassegrain models from the brand and the 8SE is the largest in the line.

In comparison Celestron CPC 1100 and NeXstar 8SE are coming from the same price range and they are also pretty much similar to each other by being a Schmidt-Cassegrain catadioptric type. However, they are also not identical and as you can already guess, the former is more like a step up from the SE line and it also brings a wider primary mirror to the tube which in theory should improve the ability of the optical tube.

Celestron CPC 1100 and NeXstar 8SE Design

These telescopes are not something that you can bring easily even from the storage room to the backyard because they are huge especially for the CPC 1100 since this one requires a very stable hand just to transfer around. They are not by any means difficult for one person to carry but will put some restraint on your back. The 8SE is about 32 lbs. heavy when all are assembled and the CPC 1100 is at least twice heavier than its brother. 

Side by side the CPC 1100 optical tube is both wider and longer than 8SE but the material used to build the main scope seems to be the same aluminum just like most telescopes in Celestron collection. You will get everything inside the box from the main scope, finder, the mounting, and their leg or tripod as well as eyepiece. Their tripods are good and sturdy enough to sustain the weight of these telescopes and seem stable enough to endure the mechanism.

Celestron CPC 1100 and NeXstar 8SE Specification

When looking for a telescope, the most important part will be their aperture because it will decide what you can observe through the optic and in this part, Celestron CPC 1100 and NeXstar 8SE are already quite different with the former offering 279.4mm or 11-inch type while the latter is a 203.2mm or 8-inch type. While physically the CPC line has longer tubes and their focal lengths are different as well at 2800mm and 2032mm, their focal ratio is the same at f/10.

Just like with any Celestron telescopes, there will be at least one eyepiece in the box and for the CPC 1100, we get one 40mm with 70x magnification Plossl eyepiece while the SE line give you the 25mm Plossl with 81x magnification. The furthest magnification these telescopes can offer are 660x and 480x respectively.

Celestron CPC 1100 and NeXstar 8SE Performance 

Moving to their performance, these telescopes are very much reliable and you definitely can see almost anything a telescope at this size is capable of offering. They are especially amazing when it comes to planetary observation because there are a lot you can see from here and even better from unpolluted sky. The first aim at the moon is satisfying and you can add a barlow lens or high magnifying eyepiece to zoom further and check out the crater like Copernicus and even mountains and all the details.

In comparison we do think they are equally satisfying but if you aim at further objects for example Jupiter, the image seems to be less crisp in 8SE in comparison to CPC 1100 but only slightly and if using low powered eyepiece, the difference may not be visible at all. Saturn is visible and looks pretty as well but if you are more into the galaxy, nebulas are equally amazing from both scopes; Orion and lagoon look beautiful and in clear sky you can see how bright omega centauri is.

Celestron CPC 1100 and NeXstar 8SE Mounting

The last part we want to mention is their mounting and as you can see, Celestron CPC 1100 and NeXstar 8SE are very different in this side because while the SE line use one arm fork, the CPC line uses two arms on each side and in comparison, this mount is indeed better because it can stabilize the main scope more effectively. The motor seems different as well because the vibration is more prominent in 8SE and for a tip, don’t assemble the tripod on top of a wooden floor since they have this pointy cap.

Celestron CPC 1100 vs NexStar 8SE

These telescopes are equally great options for those who can spend more and look for a more convenient way to observe the sky. The important differences between both telescopes is their aperture because the CPC 1100 is larger in diameter as well as has longer focal length which may affect the field of view. Performance wise they are equally reliable but for further objects, the CPC line slightly offers better image quality in comparison.
