An awesome image Mike. Those red Ha areas actually in the blue reflection neb are they real? I have never seen those before. I see a few areas of red neb which I have seen before but your image is showing them in several areas.
Is this your 20 inch and dark skies picking up what is usually not seen or is it Ha noise from a Ha sub? I imaged this last week with the Trius on the CDK17 and it gave much the same FOV. Unfortunately in my case I think I may need to recollimate my CDK or at least get the camera really square and also the filter wheel acted up.
Greg.
