Bubble Soap nebula in Cygnus

Hi all,

I decided to make an imaging attempt on a rarely imaged object, recently discovered ;-))

I spent two nights on it, because it is so faint. I also decided to use long cumulative exposure time to have a smooth result because of my heavily light polluted area (visual magnitude was maybe 3 or 3,5).
As a result, I only slept 4 hours this week end...
So, here is the Bubble in Cygnus, close to the Crescent nebula, officially discovered by Dave Jurasevich.
I used 32x15 minutes, 8 hours of data, taken with my 155EDF with flattener on 900GTO mount, ST10XME camera at -10C, 7nm Ha Baader filter. Manual focus.
The second night had a terrific seeing below 2 arc seconds, giving me perfect tiny stars.

Here is the link to the webpage, there is a link to the full size below the image:

I hope you'll enjoy the result!

Regards,

Gilles

Your full size image is very sharp. Great results from such a difficult location.

Great image. Those stars are definitely pinpoints here. Glad everything was working for you.
