Product Description

CELESTRON CGEM DX Equatorial Mount

The smaller cousin to the CGE Pro, the Celestron CGEM DX Equatorial Mount features many of the basic CGE Pro mechanics such as slewing capacity and All-Star alignment. It is great for both visual astronomers and astro-imagers alike. With a payload of 50 Ibs, the majority of larger end optical tubes can be supported on this mount. The CGEM DX is quite easy to set up and the observer can get it properly aligned and tracking pretty quickly with the All-Star Polar Alignment method. This setup gets the mount aligned properly to the north celestial pole by slewing to a bright star and giving the observance reference how to adjust the altitude and azimuth accordingly. With a maximum slewing rate of over 5°/per second, the amount of objects the observer will be able to look at in a stargazing period with be outstanding!

The CGEM DX Equatorial Mount uses the NexStar hand controller which has a 40,000 object database with information on over 200 of them. This includes the deep sky objects such as the Messier and NGC as well as solar system objects like the planets and moon. The mount’s internal motors are built with optical encoders, required for low speed tracking. The user can also run their mount through their PC using the supplied RS-232 connection port on the hand controller. To turn this mount GPS compatible, it is highly recommended the optional SkySync GPS Accessory be used in conjunction with the CGEM DX.

I have had this mount for a couple of years now and overall I am very happy with it.
I do not like the fact that you cannot even get an illuminated polar scope for it .
The DEC and RA axis are a bit sticky and can make it difficult at times to balance your equipment I really think Celestron could to do a better job with that. That would take more time and time is money but you would have a much better mount.
The mount does track very well and the go- to's are spot on . (Posted on 2/20/2017)

This mount uses the same tripod as that of the CGE Pro mount. My only qualms about this mount are (1) use of index marks to provide inital alt and dec positioning rather than electronic home positioning (as a cost saving measure); (2) bubble levels are hard to read; (3) lack of an illuminated polar scope to aid in initial polar alignment. Otherwise, this is a good, sturdy mount for the money. (Posted on 9/3/2015)
