Geoff,
So many things to suggest here for AP:
-Go to the??website and read as much as possible to get acquainted with the mount controller
-Go to the Losmandy channel on YouTube and watch all the videos, especially how to create a star model and sync for accuracy.
-Get a good AP book such as The Deep Sky Imaging Primer by Charles Bracken. He will show you all the steps from capture to final processing
-Learn all about PHD2 and how to connect to mount and guide scope
-Decide on your capture software. I am a fan of Sequence Generator Pro but NINA is a pretty good free one
-Cloudy nights are a good time to collect your bias and dark frames and start building a Library of files. They should be taken at the same temperature as when you collect the light frames.
-Learn about collecting flat frames after your imaging session to remove dust motes, vignetting and other optical defects from your lights. I never got anything good with sky flats and use a light tracing panel covered with a sheet of translucent white acrylic sheet.
-If you go to the Astro Imaging Channel on YouTube, there are hundred of videos on AP and related topics
-Think about the processing software you want to use. PixInsight is very popular, also Photoshop and some others
-You may want to get a dedicated astro camera or astro-modify you DSLR (but voids warrantee!)
Get ready to go down the rabbit hole.
Best of luck,
John
