A wide bubble

On returning from the fortnightly MKAS meeting a quick glance at the sky revealed that I would be staying up late again. As I was already set up with the apo from the previous evening I decided to try a wider field shot of The Bubble Nebula (NGC 7635) in Cassiopeia. The field includes the open cluster M 52 and bright emission nebula of NGC 7538 which I imaged recently with the Newtonian. Once a few remnants of thin cloud cleared the transparency improved throughout my imaging period with the Milky Way being quite obvious as I closed up the observatory. Details: WO Megrez 88 apo. 20x 7minute exposures @ iso1600 with CLS in DSS, CS2 & XAT.
