St4i 4.0d Image Scale Grade issue
#2
Hi Greg J.,

Could the issue be related to Surface Brightness of the objects with the '---' entries? I looked at the Messier target list provided with ST4i and M101 has the lowest surface brightness and is the only Messier object with the '---' in the image scale column. The Sh 2-216 has no listed magnitude as does IC 63 and IC 342 has lower surface brightness than M101. Perhaps the code that calculates the scale factor has a cutoff for low surface brightness objects.

Phil S.
