Re: Create a PEM curve with a camera?

I think so if you have a good pixel scale.

Subject: [ap-gto] Create a PEM curve with a camera?

Hello All, This may be a silly question, but can I use an ASI 290 mini guide camera (2.9 pixel size) through my guide scope (162 mm focal length) to create a PEM curve for my AP1100  when the day comes? Or should  it be through the   main scope.  It is a  Meade lx850 14 inch SCT..  Thinking the guide scope would avoid any mirror shift and such.. My main imaging  camera is a Canon T2i.. 

Thank you,  David
