Re: Create a PEM curve with a camera?

Hey David, I'm sure you're right to be wondering about the guide scope approach. Have you used this guide scope / main scope together before and confirmed there is no flexure? If you haven't I'd be worried that you'll build a PEC curve for the guide scope only. Stuart Heggie

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.. --
