About this image

I've been wanting to take an image of this area of the sky for a couple of months but whenever I've have had a clear sky, either the moon, the appearance of thin cloud or the dewing-up of the lens have thwarted most attempts, but finally managed to get sufficient subs.  My camera drive only allows the camera to be fitted in one orientation (portrait) so I couldn't get both Delphinus and Sagitta in one frame.  The image is therefore a mosaic of two separate images processed and merged using IRIS.  I managed to get 60 x 60s subs of Sagitta before thin cloud appeared.  It was an hour before I could image Delphinus which by then was rapidly descending into the most light polluted area of my sky and after 30 minutes had started to disappear behind a neighbours tree, so I only managed to get 30 x 60s subs.
