SH 2-101 The Tulip Nebula

I continued, trying to shoot all night, but it didn't work out—the diagonal mirror fogged up, and I had to heat it with a hairdryer. I had to throw away 1 hour of footage.

I tried to capture the stars separately with a UV/IR filter for just 13 minutes, and the stars gained color (I should always do it this way).

I only took 8 dark frames while it was getting dark, each at 180 seconds.

For the first time, I shot all night using NiNA, and I'm starting to like it more and more, especially the framing (I did it based on a previous photo)—I just inserted it, and it helped align the camera exactly.

The automatic focusing and refocusing also worked well. The mount performed a meridian flip, then recentered itself, did a refocus, turned on guiding, and continued shooting.
