it’s a pain in the ass to capture the Orion Nebula WITHOUT one satellite or another crossing across the image. Even the little itty-bitty satellites show up in a good stack.
I’ll second this. The saving grace is that the trails become almost invisible if you have more than about 20 frames to stack (assuming a straight average), and at that point you can afford to toss that one frame. I used an old, crappy mount years ago and was pretty used to tossing a third to a half of my frames for tracking errors…tossing one (or more, some nights) for a trail thru Orion was pretty much an expected loss. 😆
