CGEM DX 1100 - lifetime scope
By Too Many Hobbies
This is the sixth telescope I've owned. I've owned an 8" SCT, 60mm 3" and 6" refractors, and a 12" reflector. I bought the CGEM DX 1100 because it would enable me to explore astrophotography. I've read reviews that pan the CGEM for photography, but I don't have the budget for a $15,000 mount. Within my means, this looks like the best bet. I considered the Atlas, but in the end my familiarity with Celestron products and many positive reviews of the mount steered me to the CGEM. I opted for the CGEM DX because it offers a higher load capacity than the standard CGEM. The C11 itself isn't a problem, but when you add on a camera, guidescope, finder, filters....the weight adds up. The additional cost seemed justified by the added capability.
I've owned the scope for 8 months and I am extremely pleased with it. I've taken it to Cherry Springs Astro park in Pennsylvania - the experience was absolutely amazing. I was so mesmerized that I didn't stop until the sun came up, it was THAT good. The GOTO was remarkably accurate across the sky. Even when the alignment drifted a bit after several hours, a few simple adjustments and it was hitting new objects accurately again.
I have not tried true astrophotography with a CCD or DSLR, so perhaps I am not going to be as critical of the mount's tracking accuracy as I should be, but I have been using a Stellacam to capture DSO images. Compared to every other mount I own this CGEM is an absolute joy. It tracks like a bulldog. It makes finding objects a breeze. For example, I was hunting a faint galaxy visually in my back yard with no success. No matter how hard I tried I just could not see it. I used the "Precise Goto" feature and the Stellacam set to a long integration and BAM! there it was in the video monitor. The combination of 11" of aperture plus the Stellacam greatly extends the number of objects I am able to see.
The pluses:
1. The DX tripod is a beast. It's as close to a pier as any tripod I've ever used. Just absolutely rock solid.
2. The mount's features run the gamut. The 2 star align is easy to use, and after 2 alignment stars and 2 calibration stars it reliably puts objects near center of a 40mm eyepiece. Polar alignment is computer assisted, which I found helpful. Precise Goto is just the thing when using a camera that only lets you view a tiny sliver of the sky.
3. The telescope itself was ever so slightly out of collimation when I received it, but that is fairly simple to correct. It looks massive perched on the mount, but it is not terribly difficult to mount to the dovetail single handed.
The minuses:
1. The mount firmware was buggy at first. It would frequently fail to align without performing a factory reset. The motors initially sounded strained even after carefully balancing the load on the mount. Both of these problems were resolved completely with a firmware upgrade. The software tools and the firmware were available free from Celestron and worked flawlessly.
2. The tripod is rather tall - the minimum height of the scope is just comfortable for me at 5'10". Anyone shorter might need a ladder to reach the eyepiece.
As I've said, I am very happy with this telescope and mount. But for anyone considering it I would encourage you to to think about how much time it takes to set up and tear down. I have it permanently mounted in my back yard now, but the first few months I was spending over an hour on setup and teardown. The individual pieces are not overly difficult to maneuver, but there is a LOT of setup involved. My 12" dobsonian provides even more aperture, but with a lot less setup time. If you are thinking about photography then this is an easy choice, but if all you intend is visual observing, a big dob might be a worth a look.
