I am doing some Sky Quality Monitoring at my location and need some help to determine the best times to do the monitoring.
The rules are:
1) readings to start no earlier than one hour after end of astronomical evening dusk, or end later than one hour before beginning of morning astronomical dusk
2) moon to be at least two hours below horizon for entire survey period on a
given night (either prior to moon rise or after moon set)
In the past this has involved having to create a spreadsheet for a month, pulling Astronomical Twilight start and end times from Photopills, and Moonrise and Moonset times from SkySafari and then manually figuring out start and end times for monitoring, and calculating total number of hours and minutes available for that night.
I am thinking surely someone has come up with an app that will do that automatically? So I can for example say during this year, Oct 26 - Nov 9 are the best nights and you will have x hrs and y minutes to do the monitoring before the moon rises or Astronomical morning twilight starts.
