It was interesting to see how NINA would perform automatically all night until morning.
The first target was M45 (into the basket), then M42 (I posted it), then this one, after which I switched to the Markarian's Chain (I captured all of it, but the sky was completely washed out, so I collected the data, took a look, and discarded it). I shot from 6 PM to 6:30 AM, nothing froze or fogged up even though it was -25°C outside.
