Milton, I noticed how much it cut down going from 1x to 2x. In fact Mars completely

disappeared until I boosted the gain. But couldn't boost it enough with the 5x. I might try

it in my 8" LX200 and see what happens. It might just be that there isn't enough travel in

the focus to bring the disk down into focus (?).

And 8" will gather 4 times as much light as your 4" - so that ill help a lot.

I'm pretty sure you'll have no problems with bringing it into focus , as other people using similar scopes aren't.

My images turned out a lot better when I slowed the shutter down and lowered the gain.

I can't wait to try again. Alas, it won't be tonight.

Gain is the source of all evil for imaging. Avoid it as much as possible. You can't take noise out without losing details.
