CGEM Review Part 4- Astrophotography
Posted on 31. Jan, 2010 by Ray Shore.
After getting the necessary equipment together and waiting for a clear night, I finally got to try out astrophotography with my CGEM! I spent a lot of time yesterday getting my observatory prepared with some last minute touches. Soon after sundown, I was performing a polar alignment in preparation for imaging M42, the Orion Nebula. This would [...]

CGEM Astrophotography- The Next Phase
Posted on 06. Jan, 2010 by Ray Shore.
The next phase for me with my Celestron CGEM is to begin using it for astrophotography. I have done some webcam imaging of Jupiter with marginal results (not due to the CGEM, but other factors such as seeing conditions), but much of my interest is in imaging deep space objects such as nebula, star clusters, and [...]

My review of the Celestron CGEM continues. This article is dedicated to my experience with NexRemote telescope control. This is the first time that I have ever used NexRemote and some things were a bit tricky. But after figuring it out, I thoroughly enjoyed using it! So I hope to provide some helpful hints on getting [...]

CGEM Drift Alignment Procedure
Posted on 29. Oct, 2009 by Ray Shore.
This procedure covers the steps I take to perform a drift alignment on my Celestron CGEM telescope. Although the All-Star Aligment routine works really well to get the CGEM closely aligned with the celestial pole, I have found that the alignment needs to be refined further to be suitable for astrophotography. Note that this polar alignment procedure [...]

Celestron CGEM Review- Part 3
Posted on 06. Oct, 2009 by Ray Shore.
Part 3 of my review covers polar alignment of the CGEM. I actually used two different methods. First, I just had to try the new “All-Star” polar alignment routine that Celestron has been touting. Then, I fine-tuned it with a standard drift align.
To get set up, the polar axis of the CGEM must be pointed close to [...]
