Hi Ric,
I've been using AP for years. It has many excellent minor planet tools that make my observation planning a dream. (It has even been used to correct some Pro's opinions on what is observable and when).
As a side issue, how are you choosing galaxies for your SN search? I just completed a project for my Swinburne Astronomy Online degree on designing a SN search if you are interested (.pdf paper)
Cheers
