Hi all, here is an image of Saturn from this morning in reasonable seeing, quite a few light coloured features visible across the disk.
Here's a link to a luminance animation, please excuse the 0.5 pixel shift between the images in the animation, very annoying.

I've been testing an ASI-120MM-C camera for the last couple of weeks, thanks to Sam from zwoptical and it does seem to be more sensitive than my Flea3 FL3-FW-03S1M and also lower noise - quite an achievement for a cmos-based camera. These images were taken with the ASI camera.
I've been using the same capture settings that I would on the flea3, and a 4x powermate instead of my normal 5x powermate (which works at 6x with the spacing). The change from 6x => 4x pretty much cancels out the pixel size difference between my Flea3 and the ASI camera and allows an equal comparison.
I also like the t-thread on the top of the ASI camera, it means I can screw it directly onto one of my favourite 2" non-tilt adapters and it fits very nicely into my imaging setup. I can change the spacing if need be with standard t-thread spacers.
The only issue at the moment - for me at any rate - is that I have to use firecapture instead of my normal Linux capture software, meaning I lose access to some things that I need (eg 2x2 binning and integration with my wheel). But Sam has promised me some programming info so I can write a Linux capture program... hopefully not too far away...
regards, Bird
