Twilight times for Image start/finish Parameters

Hello! It would be helpful if SGPro calculated sunset/sunrise, civil twilight, nautical twilight, and astronomical twilight and allowed these to be used as part of a sequence start/finish times.

Typically, I want to image objects that are above 30 degrees from the horizon and to start/finish after astronomical or nautical twilight.

For example, when I am following a short period variable for photometry, I want to stop the sequence when nautical twilight starts in the morning. At that time, I’ll start my twilight flats sequence and then end the sequence.

Currently, I look up these times separately and input them into a sequence each time I might run it

Having the ability to tell SGPro to start/stop a sequence when it is above 30 degrees and that twilight has (or has not) occurred on that date would be useful.

Thank you and best regards.

Perhaps merge with Astro Dark added to Planning Tools - Feature Requests - Main Sequence Software

Yes, we’re planning on adding some better context into the planning tools like twilight as well as moon ephemeris.
