Astrophotography Exposure Length with CG-5?Posted By Rick Hageman |
Hi,
What length of exposures at 400-500mm have been acheived with a CG-5 mount? Both guided & unguided. I have a Celestron Onyx 80 EDF and a Canon 40D.
Any advice on another mount in this price range (used)? I have about $500 to spend on the mount/tripod.
Also, any links to good "hop up" or "massaging" to improve the mount. I've already checked out most of the verbage on astronomyboy.com.
Thanks for any help,
Rick
