Bubble Nebula - SHO

Everyone's favourite bubble in space.

This is just 1.5 hours each in SII, H-alpha and OIII for 4.5 hours total with my Esprit 120ED, 0.77X reducer, EQ6R-Pro and QHY 268M. A one night job whilst I was away in Cambridge with some friends. Not much data so had to work hard with the processing on this one!

I really like that. Great structure in the nebulosity surrounding the bubble and in the lobster claw too. M52 nicely resolved too. Well done.

That's a beautiful dramatic image.  Naming it "The Bubble Nebul" doesn't quite do it justice with the Lobster poking it's claws in and the open cluster as well.  Excellent

Many thanks! There’s actually quite a bit of fine detail I’ve lost in the bubble with the histogram stretch to reveal the fainter surrounding nebulosity. A very difficult balance to strike, and I wasn’t able to recover much with HDRMultiscaleTransform in PixInsight. I’ll give it another go at some point. Maybe some kind of masked stretch or the like.
