The Vixen GP and the slightly larger GP-DX mounts can both be outfitted with the SkySensor 2000 with 13,000 object data base. I think GOTO is a must for CCD imaging. The SkySensor also has a good polar alignment routine and the GP-DX a good polar scope either of which is good enough for 2 minute unguided images. Most smaller mounts on the market do not have sufficiently good tracking capability. The next step up from the GP and GP-DX would probably be a G-11 Gemini or Celestron CGE. The GP clones such as the CG-5 (I speak from experience) do not have the tracking accuracy of the Vixen mounts from which they were copied. -----Original Message----- From: utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com [mailto:utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com] On Behalf Of Rob Ratkowski Photography Sent: Wednesday, October 04, 2006 5:23 PM To: Utah Astronomy Subject: Re: [Utah-astronomy] Which 80 mm refractor to buy? Aloha Ann I'll put my 2ยข towards William Optics, I have their 80mm Fluorite Doublet and I'm quite happy with the performance and price. As for a mount, I use the 80mm on a Vixen GP with great results, solid and fairly light weight, excellent tracking and all fits into a small Pelican case.
