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!!!

The Thing

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!!!

It is healthier to be mutton dressed as lamb, than mutton dressed as mutton!

Flippin awesome. I agree with Faye!
