ZWO ASI183MC Pro Camera
Skywatcher EQ6-Ri Pro Mount

Post-processing Details:

I did pull the stars off of this one so I didn't blow them out but I didn't really stretch it too hard. There was a lot of good data. Stacked and stretched in Pixinsight, then a little touchup on contrast in Photoshop.

Image Details:

This is M33 (The Triangulum Galaxy), weirdly enough, in Triangulum. This galaxy is so large that it barely fit in the field of my 91mm scope. I've seen this object at least 100 times in varying quality of skies from 6" to 40" telescopes and it never looked even close to this. Incredible detail and some amazing internal nebulae that even have their own NGC designations. I couldn't wait for it to come up this year and it did not disappoint.
