Re: Comparison of CG5 mounts
- View SourceIt was about 6 months ago I did the PECtool training after going through many days of searching various forums for just the question you have asked. The one constant was that PEC works on the new Celestron CG5 and that Celestron will not confirm the info. After reading many forums individuals that did the average of 7 to 10 PEC's had the best results. Since the full moon was out it was the perfect time to do PEC training. Ten runs, then averaged in the laptop, then saved to the mount memory. You need the most current firmware to PEC to the motor memory board.
The mount is very stable even on windy days - but with the everything on the nexstar 5 optic I'm less than 15 lbs.
Sorry I can't confirm my sources but it is out there if you want to spend the time reading forums until you are brain dead. I think the mount is a great first mount to see if you want to get into astro imaging. Just remember that 50% of the mounts ratings = a stable mount = 15 lbs. You can go higher but everything I have read means extra weights, no wind, and a lot of balancing work.

I have my old nexstar 5 scope mounted on the CG5 and uses the small orion autoguider finder scope with my old meade dsi pro imager for auto guiding. The first thing I did was to spend and hour under the stars and use Celesron's PECtool (yes PEC does work on the newest CG5) and did 10 runs with the auto guider which removed most of the gear errors. For $600 the mount can't be beat. My next purchase is a newer canon to replace my old 10D and get live view for accurate focusing.
