Iris nebula vdB 139

M3 – NGC5272
5hrs of total exposure using 10min subs. This was to get the very faint stars at the far periphery as well as the brighter centre that would require lower exposure. I used an extended full-well-depth mode on the camera from this to give a full well depth of 75,000e to prevent the core blowing out in the 600s exposures. by Dean Ashton

Celestron 9.25 EdgeHD with 0.7x Focal Reducer, QHY268C Camera, Optolong L-eXtreme Filter, Exposure: 10x600s /f7. By Dean Ashton
Lobster & Bubble Nebulas by Dr Nigel Price
This is the lobster nebula with the bubble nebula centre (Wolf Rayet Star nebula – like the crescent). You can also faintly see CAS A supernova remnant in the top left corner as a serated blue outline which is not supposed to be possible with a 108mm of aperture but hey ho! All of these can be found in the majesty of Cassiopeia, field of view is approx. 3 by 4.5 degrees.
