Thanks Ivan. Yes detail on Ganymede. I'm still getting used to that scenario even with average seeing. This is already a combo stack. Only a 1500 frame moon stack so this is about as far as I can tweek it without introducing artefacts.
Hi Peter & thanks. Well I've still got the 14" newt but no, I'm getting a better result with this extraordinary C11 that I still reckon has an uncannily great set of optics in her..The seeing is still the limiting factor for me. Nothing special about this seeing & I wouldn't give it any more than a 5-6.The interesting thing is though, it's the first time this year I've seen the high & mid levels 'join forces'. When all 3 are lined up on the same heading, that's when I'll get my seeing.
Thanks Trevor. lowering the gamma to 50% on the live feed has always been my bench mark. If you're seeing details right to the poles with this gamma setting you're going to do ok. Naturally I bring back the gamma to 100 before any AVI is taken.
What kind of camera are you using? And what kind of exposure times, gain and gamma have you appplied?
In my short experience (usink dbk21 color) I have used gamma around 50 both when viewing on screen AND recording. Should gamma be set higher than 50 (you mention 100)? Or is that dependent on the camera...

I'm using the Imaging Source DBK618. My exposure times directly relate to what frame rate I use, but before I choose a frame rate, I must consider the seeing, so it does depend a lot on the seeing. Generally for good seeing I would use 30FPS with an exposure of 1/30th-1/38th With roughly a 75% filled histogram with my C11/2X barlow (F20) For 60 FPS (which I use for average-poor seeing I'd be running my fastest exposure with maxed out gain.
I always use 100% gamma which is default or linear. I have experimented with lower gamma but was not happy with the results.
One more, this time at F30 - Had to try it. I've had worse results but in better seeing I hope to receive a better result. Going to be clouded out for a couple of days I think. Not happy!
. Great planet pics as usual !!!
