Has anyone here had any personal experience with this mount? I am new to astrophotography and it looks like a great mount for getting your feet wet. Not to mention it's advertised to be very very accurate and with little periodic error. Any thoughts, opinions, and expertise is welcome.

Here is a link to the mount

I have been using the Astrotrac for a couple weeks now. In a nutshell it tracks very well for wide field, its small and portable, very well made, but will not handle anything more than a telephoto DSLR lens IMO. I attached an image made with a Canon XSi using a 200mm 2.8L lens. It is a 100% crop to show roundness of stars and detail. It is a first light of all equipment so be gentle smile I shot 15 images at 300 seconds at iso800 and stacked them in ImagesPlus. I tried my Takahashi Sky 90 which weighs less than 10 pounds including camera and reducer and it would not carry the (very unbalanced) load. As far as a good portable widefield mount for DSLR I am very happy with it. If you expect to attach any telescope I would highly recommend a GEM. Hope this helps.
