Hi Russell,
Thanks for the information. I was really hoping I would hear that I could extend that exposure time to at least 60sec.
Since the scope is natively F10, the only way to get more is to buy the reducer/corrector which will give me more field of view, but also bring it to F6.3. Looks like something needed on the list.
By the way.. I had a look at your site. You have some very good images
Cheers
Wayne
