Pete - the answer is to bin - M27 told me

Depending on the seeing conditions some data might not need to be binned. Looking at the ccd_suitability The GT131 with the 294 is the correct pixel size for good seeing conditions, but if the seeing drops to average then software binning will be needed.

The GT131 looks like a fun scope to image with, but it must be massive!

OK

So I found out that my workflow was totally incorrect from Pete's last post......

A dive into my old signal processing textbook, gave me hints but then looking at some computer graphics textbooks told me what to do.....

I have a LOT of reprocessing to do!

Thanks Pete!

 

I agree, p7 2x2 with 4+un pixels would be perfect and get the most out of the pier and local seeing conditions :) the 294 sensor has pixels to spare so its not a big deal like you wont have enough left lol

great...Yes the software bin especially on that camera is so worth while....and you get better results than hardware binning

That M27 is nice and deep 

Don't forget about BlurXterminator. Make a small preview and then manually dial in the settings with live view.
