Title: Cave Nebula region
Post by: MarkS on Nov 10, 2015, 21:48:54
Here is the Cave Nebula region, extending just as far as the Bubble Nebula at bottom of the extreme left.  Taken at the beginning of September but only now processed.

Modified Sony A7S on Tak Epsilon 180ED. 2 hours of data in 3 minute subs at ISO 2000.

There's an incredibly bright H-alpha object 3/4 of the way between the Cave and the Bubble.   I don't know what it is.

I think that's NGC7538

Bloody 'ell Mark - really pissing me off with all these gorgeous wide-field images your posting in such a short time.. ;-) I just can't believe you have got such a smooth, detailed & coloured image (one shot) in only 2 hours.. You must be well haps with the results you are getting now.

Thanks for your comments.   Yes, I'm pretty pleased with this imaging combination.

I've still got a few "in the bag" waiting to be processed.
