+5 been using it for a few years, has some cool features.
1. Best pairs will tell you what stars are the best to use for alignment, I used this a lot with my Meade lx90. Previously this was a separate program but it was then added to AP.

2. As mentioned in last post the resource selection in v2 is awesome. Even has many popular prime lenses already listed. And if you email support they will add an equipment you have.
