Telescope and Mounting

Astronomy is not the hobby of everyone and amidst various digital trends today, it is probably difficult to meet someone who has the same hobby as yours. However, we are sure there are so many people out there that carry the same interest in celestial objects just like you and we may have the same taste as well about the way we enjoy those that are far away from our earth. For this hobby, you may not need much but a reliable telescope.

Telescopes are not a must have for the majority of people but it is a crucial tool we have to own to see those planets and other objects our eyes can’t see properly from here due to the extremely long distance. The main device itself may vary depending on the person using it as not all of us have the same goal and the same preference. However, no matter the goal, aperture in a telescope is still the most important point to consider when looking for the right option.

In general larger aperture will produce clear images in perfect condition means the optics are perfect while the focal length affects the image size. Small telescope is ideal for planetary observation and long focal length is great to let you see details, moreover when combined with large aperture as well such as the Meade LX200 Vs LX600 but, for massive objects a shorter focal is better to let you get a view of the whole area and make sure we get a better experience. 

However, there is another factor that we may forget at times when looking for a telescope and this is their mounting itself.  Telescope mounting is very important because this is what you will be placing the unit on above the tripod and in general navigating as well as keeping the unit safe during application.  We are sure most people already know there are two types of mounting; equatorial and alt-azimuth types in which are completely different from each other.

Most enthusiasts will prefer the equatorial or EQ mount because they are more convenient as the movement is following the natural movement of your object but for beginners they can be complicated to start with as we need to align them properly and adjust the weight too. Alt-azimuth can move the telescope in any direction but less convenient as it is not following the movement of the star and we have to adjust two positions while moving but, since this is just like regular camera mounting, most people probably are more familiar with how they work.

About CGEM II and CGX

If you are here then it means you are also currently looking for a telescope mounting and just like everything, it is best to choose based on your own preference or what you need the unit for. With telescope mounting we should match it with our main tube first because not all telescopes have the same system and thus, some brands may be better being paired with the mounting from their own family as well or do check the specification of your main tube first.

There are many good brands out there that offer reliable telescope especially the main tube but not all offer a separate mounting system yet, Celestron is one of the few that not only has amazing telescopes but also reliable mount for your current tube or if you want to upgrade the mounting that comes with the main telescope. They also carry few models to choose from and most of them are instantly paired with the respective telescope lines or come in a pair with the tube already.

Among those mounting and the type of saddle they have, their CGEM II and CGX mounting are probably the most popular to choose. As you may already know both of them are an equatorial mount which is why most people are choosing them to upgrade their older mount or to have a more reliable system for their main tube. These two are also coming in a set with the tube so if you somehow damage your 925 HD or 1100 EdgeHD then these two will match right away. 

These assemblies are related to each other and chances are they also carry so many similarities besides being equally reliable. They also match the same type of telescopes and we can use them interchangeably if you need to but, being a different model there must be some differences as well between CGEM II and CGX mounting from Celestron. In short both of them are the upgrade of older CGEM mounting but in comparison the latter is forming a new line which is aiming for even more reliable performance. 

CGEM II and CGX Design

As you can see from the sample picture above both of them are quite bulky but side by side the CGX is looking like a different mounting altogether and even from the first sight this model is very rigid or robust so we guess it also comes with higher load capacity and it is true with the 15 lbs. additional load compared to the CGEM II which is rated up to 40 lbs. already. What’s amazing is their weight is not far apart from each other with CGX about 4 lbs. heavier while the CGEM II is 40 lbs.

From the material they are very durable and robust without any flimsy part but we also like the fact that they include tripod here with the mounting yet, we are not very sure whether these 20 lbs. tripod will be able to sustain both main tube and mounting weight at maximum capacity. From the external differences, besides the overall shape and construction, the new CGX did make the stance on the mount a little bit lower and stouter.

CGEM II and CGX Saddle

Moving further, what makes CGEM II and CGX very similar to each other in our opinion is their suitability itself because both of them are adopting the same dovetail saddle with dual fit feature which means they can be used with wider CGE and D-style plate, as well as Vixen or CG-5 saddle plate. In our opinion this is what makes these mounts become a great choice for many since matching the saddle plate limits our option and these two will give the versatility for you to basically accommodate more types of telescope.

It also cuts the budget to purchase an adapter since usually we have to add something in between the main tube and mount if their systems are not compatible to each other. Celestron also has other mounts with the dual saddle plates system such as the CGX-L and Advanced VX for the options but with these two you can mount almost any optical tube.

CGEM II and CGX Tripod

The next part we want to talk about is the tripod because this is the leg and support for both the main optical tube and mount itself. We personally always concern about tripods, especially those that come in a set with other products as they often flimsy and not reliable enough but Celestron seems to understand this worry as well by upgrading the tripod in their mounts. What you can notice with both mounts is their tripod will have a wider stance for better stability.

The material seems to be the same and the features such as marking on the extending part of the legs are still the same as well. These markings are very useful in our opinion because usually we have to adjust the leg several times to get the perfect balance but now we can see and put them on the same height just with one try.

CGEM II and CGX Motor

The last part we want to mention is their motor system and in this part while their physical design changed, both CGEM II and CGX are actually using similar systems or the same spring loaded brass worm wheel and stainless steel worm. This system ensures a smooth movement and tracking to make sure the best experience but in addition CGX also has new software to control the mount directly from the computer which is more powerful than their previous one.

CGEM II vs CGX

These mountings are amazing for their versatility and ability to hold a huge weight but slightly different when it comes to design and capacity. CGX design has been tweaked to maximize the load capacity which is rated up to 55 lbs. or 15 lbs. heavier than CGEM II by removing some parts and redesigning the mount. The main system is still the same including the mounting but they also include new more powerful software.

- Edge HD Optical Design
- 279 mm (11”) Aperture; 2800 mm Focal Length; f/10 Focal Ratio
- SkyAlign Navigation & Tracking
- EdgeHD Optics Coma Reduction
- Mount holds up to 75 lb load capacity
- 144 mm diameter worm wheels
- Two all-new dovetail clamping knobs
- +20° of additional tracking past the meridian

Conclusion

All in all you can choose any of these mounts based on how much load you need since most who are buying them will mount cameras as well. If your gear is heavy and you will upgrade it later, we do recommend getting the CGX to future proof your setup.
