Hi Guys
Having quite a few problems with imaging Mars, I am using a C11 and DMK mono firewire, the camera settings I have tried are brightness 0 to 20, gain all through the range but try and leave it on 0
Shutter speed from 1/30 upwards depending on frame rate but usually leave it on 1/30 @ 30 FPS. Codec Y800.
I am getting a very pronounced onion ring effect I have collimated the scope to the best of my ability, I used Polaris and defocused then got the black circle in the middle.
It still looks like the collimation is out.
Please see the image below, any ideas would be gratefully received.
Left picture at F/10 right hand side at F/20 with a barlow, 4x imagemate is even worse.
