... What about the Z7? A guy over on the coin photography forum on CCF uses a Z7 with good results. He apparently uses Capture One. I have not use it but would appreciate any comments on how well it works vs EOS utility. I'm the guy over at CCF forums and just found my old ID here. I'd say that Cap...

I used to do astroimaging, but give it up due to advancing age (better to stop hauling around those heavy mounts, etc. before I hurt my back rather than right afterward).
