This was just a quick experiment last night with the Sony A7S on the Tak Epsilon - 2 hours of data.

The gradients across the image were horrendous - it really needs a darker site and maybe a light pollution filter also. But a target like this would only usually be tackled with a cooled mono CCD.
I'll have another go at this and do it properly next time.
Do I regret not buying a cooled mono CCD? I think not!!!

Is this 90s subs again? And just co-added in IRIS. Looks like it's gone really deep.
This was one of my expectations for the camera so I'm glad that's being borne out.
Shows great promise :)
Why's it B&W - thought your camera was colour ;-)
Looks very promising....
Pretty amazing, I agree with comments above including:
QuoteWhy's it B&W - thought your camera was colour
and How long were the subs?

The subs were actually 5 minutes. 30sec subs would have given identical results because of the low read noise but without burning out the galaxy cores :oops:
B&W because I summed RGB to reduce noise. Next attempt will be colour.
Gosh Mark, looks like you have gone back to the BIG BANG!!!

Flippin awesome. I agree with Faye!
