Hi, 

 asiair just gave me an effective focal length of .76 by.58 arc sec .I plan on using sharpcap as well but in the instructions for selection of the correct

catalog , it says go with the full fov on the first and 20% of the second measurement when choosing. Why the 20% and not full? Am I miss understanding here?  Thanks jk

Which platesolving application are you trying to use with SharpCap, as there are several?
