+4 ... I have used v1.6 and now the betas for the past year or more, and it has been a great help in all kinds of situations.
One of the great features is the "Combinations" tab of the Resources window. Say you have an imager (DSIc or whatever). You put a f/6.3 reducer before it and strap it to a 8" SCT f/10. What arc-seconds per pixel? Astroplanner will let you know. Limiting magnitude? Field of view? You change to a DSLR. Easy to find the answer ...
Highly recommended.

Tony Barry
