Sh2-129 Squid Nebula
Sh2-129 Squid Nebula (HOO with RGB stars) by Barry Trudgian
M33 by Dean Ashton
M33 with Ha and RGB combined. Specifically 11hr20m (68x600s) of RGB and 4h20m (26x600s) of Ha combined. As you see, combining the Ha makes a big difference to the image. M33 is very active in star formation. THe Ha is also providing greater resolution of some of the larger nebula in M33 with structure in NGC604 becoming clear.
NGC 3031 – M81
Taken over three night during 2021 and 2022. Celestron 9.25 EHD @ f/7 74×600 sec subs using a QHY268C camera through an Optolong L-pro Filter. By Dean Aston

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.
