Re: [APML] Registering Star Charts

Matt;

     Very interesting comparison.  I like it!  Interesting too is the location difference on M52.  Everything else aligns okay.  Thkx for the post...joe  :)

However, curiously, the charts are much harder to read, especially after they are rotated and scaled by RegiStar. I'll stick with my usual resolution of 1024x768.

I think this is smart of Bisque, because when viewers see these charts, their inclination to purchase TheSky may be increased.
