NGC 2244 "Rosette"

Suddenly, the sky cleared up.
I took out the TTArtisan 500mm 6.3ED to test it.
In the cold (around -10°C), the autofocus motor struggled to turn the focus ring—it only worked intermittently, so autofocus didn't function properly.
I never knew how to focus manually, and I still don't; the Bahtinov mask didn't help either. As expected, I didn't achieve focus.
Just in case, I shot NGC 2244 for testing. The stars bloated unacceptably, as expected—even StarNet didn't help.
It's too early to judge the optical quality; I still need to fine-tune the drive and get proper focus...
After adjusting the mount, I had no issues with guiding—drift was around 0.5-0.6".
At the end, I broke the remote and almost dropped it from the 5th floor. Had to use duct tape...
In the cold, the Wi-Fi on the remote glitches more often—I'll probably go back to using a cable.
