Sadr Region

[Stub Mandrel]

Ever wish you had taken more subs... I  couldn't see the Elephants Trunk so i took 20 90-second subs of Sadr, slewed and discovered the ET was still behind a tree, but went to the NAN instead of going back to Sadr. So a hideously noisy image, with a rather warm DSLR (it was t-shirt time at 3:00am last night), but boy there's a lot in this bit of sky!

Not to bad with the short exposures.

Hmm... I saw a post which made me think I have my sigma kappa number wrong in DSS.

I tried auto-adaptive weighted average on the same data and got this... hmm.

Tidy work for the integration time.
