Hi
I thought I would post this even though I am planning on adding more data later to smooth the image a bit better. It is a wide field of the following DSOs
NGC7635 - AKA Bubble nebula
M52
NGC7538
NGC7510
Sh2-157 - "Lobster Claw" nebula
Sh2-161
There may be more in there but I haven't had time to look any further
I took this over 2 nights with 8x20 minutes Ha and OIII and 10x20 minutes SII. There was a period of poor seeing last night when doing the SII data courtesy of some thin misty cloud going overhead for about an hour. It was taken with the Takahashi FSQ106ED at f5 with Starlight Xpress H36 on a Paramount ME auto guided with an OAG and Lodestar camera.
I have tried the Bubble nebula several times before, both with small and large field of view all of which can be seen in the picture gallery on my website http://www.imagingtheheavens.co.uk (http://www.imagingtheheavens.co.uk/) this is the widest I have gone and gives a bit more context to size.
I have posted a larger version 2400 pixels wide at

Thanks for looking
