In the centre of the image is dark nebula Barnard 147 & top right is
dark nebula Barnard 146. This field is just to the left of Sh2-101 The Tulip Nebula in Cygnus.

Taken in H-alpha, this is going to be one of a three panel narrowband panorama. It's going to take a while going off the 10 hrs just for one filter for one panel !

The subs for this image were taken over a few nights from June 22 to July 16 2014

I will just add that this, as with all my images, are taken from light polluted Manchester UK and the average SQM for this image was 18.3 (18.1 to 18.5).
