Still having fun trying to do this mono processing. See attached pic.
I took advantage of Martin Pugh's kind offer of some free Eta C imaging files to play with ( Thanks Martin ) but when I come to stack each filter I get this message. I can stack the image files no problem, but as soon as I add the appropriate Dark, Bias or Dark Master to the list then it all stops. I have fiddled with every DSS setting I can find in the registration option in but no luck. I am using the latest 64 bit version, 4.1.0.
Obviously I am missing something but no idea what. Clues please.
