Telescope Types

Our universe is too beautiful to not be explored but to do so there will be a huge leap in our technology first since our current one is still not capable of going further away. Chances are it needs decades or even centuries to develop those that can transport humans for various purposes out of our atmosphere as well as sustaining life out there. But, at least now we can see and peek at what exists outside this planet through a piece of telescope. 

This is a very useful device that lets you see anything exist further away and the first time it was invented, the usage is still limited to only aim what’s on earth but Galileo Galilei aim it at the sky and since then he is more related to the tool in comparison to the real inventor himself. Another important figure that plays an important role in telescope invention is Newton with his Newtonian telescope because the original design is using lenses and it suffers from chromatic aberration unlike the mirror one.

Newtonian telescope is using mirrors instead of lenses and similarly, the light from a star goes inside the optical tube and is first reflected on the primary mirror located at the bottom of the tube. The primary mirror is the key of a Newtonian or reflector telescope as its job is to collect and make the light beams converging towards the viewer from its eyepiece. Before visible from this eyepiece, it needs to be reflected on a secondary mirror first which is installed next to the front aperture of the telescope.

Another type of telescope that is very similar to reflector is Schmidt-Cassegrain but this is also similar to a refractor because it is a combination of lenses and mirrors. The SCT catadioptric is mostly using the reflecting system but it also has a corrector lens to eliminate aberrations that would result from the mirror design alone. In this design the light comes through the corrector lens at the front of the telescope. The light is reflected from a concave primary mirror at the back of the scope which focuses the light to the front of the telescope.

This is then reflected again by a smaller secondary mirror and finally the light travels back through a hole in the primary mirror to the one located on the rear and where we place the eyepiece to take a peek of the image. The design and mechanism of SCT allows the tube to be much shorter since it is folding the light which means we can build the model with higher focal length while keeping the tube short.

About Meade ETX 125 and Celestron NexStar 6SE

There are actually various others in the collection of telescope types but in general they are either refractor, reflector, or a combination of both such as SCT which is using catadioptric design. If you are here then it means an SCT or catadioptric will benefit you the most and this model is especially amazing for both planetary observation and to be carried in your spot hunting activities as the unit will be very compact. Since they are very popular, all telescope brands usually have at least a line of SCT in their catalog. 

We recommend to stick with popular ones that are focusing on the device because they tend to be more reliable as well and among those, Meade and Celestron are two amazing choices you may want to consider when looking for a great buy. These brands are very popular and we are sure you have heard them often when browsing through the brands to shop from but what makes them great options is because the products they offered are well-made and working reliably.

They have tons of telescopes and accessories to choose from but for the catadioptric model we do think Meade ETX 125 and Celestron NexStar 6SE are going to be very ideal options in the mid-range. Both of them are not the biggest they carry in the catalog as you can find many with larger aperture but both the main mirror and focal length of these models should be enough for different types of observation yet, we also think they are best for larger and more prominent objects.

Another thing we love from these telescopes is their system because these are coming with computerized mounts which may not be the cheapest if you are looking for an affordable scope but they are sure convenient. Meade ETX 125 and Celestron NexStar 6SE are pretty much similar to each other as a catadioptric model but the aperture and they might have some other differences as well that affect your buying decision. 

Meade ETX 125 and Celestron NexStar 6SE Design

The best thing about SCT is their form factor because as you can see, the main tube of these two are very short and much shorter than they should if using a true reflector design. The tube is made from metal for durability but in comparison between Meade ETX 125 and Celestron NexStar 6SE, your NexStar will be slightly longer than ETX since this model is also carrying a larger aperture. The diameter of the ETX tube itself is 5.75-inch while the latter is 7.1-inch.

From the build quality they are very sturdy as well and since they are in a set there are mounting too in the box. The mounting they packed is an alt-azimuth type but the ETX has double fork type and holding the tube on two points instead of one which may improve its robustness but, you can change NexStar mount with something like CGEM II Vs CGX if needed such as when adding gear on top since the vixen saddle will fit on these mounts double system.

While these models are using the same catadioptric design, they are not exactly the same because if NexStar is an SCT type, the ETX is a Maksutov. These two are similar but different on their corrector plate option as SCT uses an aspheric lens while the one in Maksutov is a meniscus or highly curved spherical lens. In general you will hear that Mak design results in better image quality and one of the reasons is due to its smaller secondary mirror thus there is less obstruction on the light path.

Meade ETX 125 and Celestron NexStar 6SE Specification 

Moving further, let’s see what Meade ETX 125 and Celestron NexStar 6SE can offer and starting from the main tube first, as it has been mentioned above that the 6SE is a model with bigger aperture and this one actually has an aperture of 150mm or 6-inch in comparison to the ETX 125 with 127mm of aperture or 5-inch. As for the focal length, the NexStar is also packed with 1500mm with f/10 focal length compared to ETX with 1900mm and f/15 ratio.

Besides the mounting, they are also packed with eyepieces to let you start right away and in ETX 125 you will get Super Ploss 9.7mm and 26mm in the box. For NexStar 6SE it will give you only one eyepiece or the 25mm type.

Meade ETX 125 and Celestron NexStar 6SE Performance 

Now let’s see how Meade ETX 125 and Celestron NexStar 6SE perform because this is the most important part in any product and in general, both of them are very reliable. The image quality you can peek from these telescopes are clear as long as you can find a good spot to use them but while Mak is often said to have a better image than SCT, the 6SE is not falling behind here and they are very comparable side by side as they are detailed and bright.

Due to the difference in focal length however, the image seen from ETX 125 will have a narrower field of view which makes this model not as versatile for those objects that have a wide spread area. But, bright objects like the Orion nebula are looking amazing through any of these models.

Meade ETX 125 and Celestron NexStar 6SE Mounting

The last part we want to mention here is about their mounting but they are just as good too. These GoTo mounts are amazing for those who are looking for convenience since they are computerized and they are also coming with tracking functions to ease your job. The mounting on 6SE may not be as stable as the double fork type but they are reliable to hold this much weight. As for the database, NexStar is packed with 40000+ databases compared to the 30000+ database of ETX 125.

Meade ETX 125 vs Celestron NexStar 6SE

Both of these telescopes are good for the budget and ideal for those who will carry the unit around too as the tube and mount are designed to be travel friendly. The difference is 6SE has bigger aperture while the later has longer focal length due to being a Makstutov but other than these they are very much similar to each other. The ETX also gave two plossl eyepiece and double fork mount for stability.

Conclusion

All in all you can pick any of them as they are very much similar to each other but, personally we prefer to find a model with larger aperture to promote the best image quality while keeping the focal length moderate to get as much from the object.
