NGC 7635 The Bubble Nebula

[orionoffelt]

Had a go at imaging the Bubble on Monday night the first time this summer that I had dark enough sky's to try imaging with Celestron CPC 280 mm at F 6.3 a 400D modded camera ISO 800 UHC-S filter 25 x 6 and 3 x 10 min subs Nebulosity 2 DSS PHD and PSC3 Thanks for looking.

Cheers

Bob I'm impressed. Had a go myself earlier in the week but was beaten off by cloud and mist. You've picked out some beautiful detail in the bubble and lovely, deep, star field behind. Clear nebulosity too.

An inspiring image.

Thanks Mark for the nice comments and it was a good clear steady night so I was lucky for a change hope you get a chance at it shortly

Cheers

This is a tough one for a DSLR and you have pulled a lot of detail.

Flats would make a huge difference to this because of the insistent vignetting of the SCT. It would all disappear with flats, though - or so I believe.

Good stuff,

Thanks for the helpful comments and maybe next year I will progress up to a one shot colour ccd

Nice- I agree with Olly - flats would have helped, but wow what a shot with a DSLR!

Hi Olly and Paul thanks for the comments regarding flats but I did calibrate this image with 30 flats taken with a LP light board and the histogram was 50 % on the camera readout I have tried creating a master flat average stacked in Nebulosity and another master in DSS with a median stack both of these masters remove the dust marks but do not correct all of the vignetting any advice would be helpful.

Cheers

Bob
