Yeah, sorry this thread went a bit off track....i didn't mean it to!
. We can continue to talk about this is another thread (once/if it's split) as we should just be inspired by Mike's image.
Thanks for your advice though. I will up the gain in future when I use the barlow. I think it will take a bit of time to sink in when you start talking about magnifications of 1600x or focal lengths of around 10,000mm. I just didn't think the atmosphere would allow you to magnify so much!! With those sort of numbers, jupiter or saturn must look like a fuzzy blob in the actual AVI, even in scopes with an aperature of 10" or 12"?? How do you get any detailed frames from an AVI with figures like that? I would greatly appreciate it if I could see some single raw AVI frames with a focal length that high.
Thanks
Daniel
