NGC 7635 Bubble Nebula and friends

This was taken on the night of 28 September 2015 while waiting to observe the Total Lunar eclipse. It consists of 5 hours in Ha in 10 min subs. When the eclipse went total I took the opportunity of getting some OIII but not enough to use yet. Equipment: Megrez 90 scope with 0.8x focal reducer and Astrodon Ha filter.


Top left is the M52 cluster, top right is NGC7538 (or Sh2-158) and bottom right is part of Sh2-157 the lobster claw nebula. The little nebula to the right of the bubble is Sh2-159
