From Wikipedia: The Owl Nebula (M97) is a planetary nebula approximately 2,030 light years away in the constellation Ursa Major and is estimated to be about 8,000 years old.
The Surfboard Galaxy (M108) is a barred spiral galaxy about 46 million light-years away from Earth in the northern constellation Ursa Major. It is nearly edge on when viewed from earth.
Both objects were discovered by Charles Messier’s observation companion Pierre Méchain in 1781.
Processing
Processing was with PixInsight utilizing the RC Astro plugins. This processing utilized the Multiscale Adaptive Stretch tool.

Previous Captures
I made several changes to the imaging train in between my 1st try last season and my current try. First, I finally found the source of the flares around bright stars. It turns out the SCT is quite sensitive to the dew heater, and it really needs to be run at absolute minimum power needed to keep the dew off, thereby minimizing thermal warping of the corrector plate. I added a proper dew heater controller with a thermistor, which kept the overall dew heater power at a much lower setting, and suppressed the flaring. This allowed me to increase the field of view and use the larger camera sensor on the 2600, and that allowed capturing M97 and M108 in the same image.
Annotated Image
This is a galaxy rich area of the sky. I was quite pleased with the results as most of the galaxies were identifiable before the annotation.
