I am aware of the existence of equatorial mounts, but only the basics of how they work. The fact that they work at all is evidence against flat Earth claims without appealing to NASA. Not that it helps.
What software do you use? I have barely dabbled in GIMP, and I know Adobe has popular tools. Is there more out there?
I primarily use Pix insight. It's like Photoshop but specifically made for astrophotography. There's a lot more math in editing astrophotography photos and it makes it real easy to understand and use it without being a math professor
