It was probably discussed many times but……. Just curious if you all have some rules about starting time.
What Time do you start shooting ?
When do you begin shooting.

When it is dark.
Usually, I can tell when my Guide Scope image, and my Main Camera images are showing nice stars.
Approximately an hour after the predicted sunset. But no particular time.
I generally start around 2/3 of the way between the start of astronomical twilight and night. This assumes I'm not shooting West of zenith. There's a negligible difference in SNR on my subs when shooting broadband. Any earlier than that and it becomes noticable.

After a too-early start on an imaging session in 2022 (M106), I adopted a “photographic twilight” when the sun is 15° below the horizon, half-way between astronomical twilight and night. It’s worked out well.

I’m too busy getting kids to bed most nights and end up starting around midnight, 11 pm if I’m lucky.
I start at nautical dusk and discard some of the subs that are still too bright
It depends a little bit on the time of year. During the shorter nights, I set NINA to spool things up about 15 minutes before Astronomical twilight.
