Glen, my point was that a black jpeg doesn’t show any detail or given any clue as to the values of the amp glow above random background. I got excited when I saw a link to his cloud drive but then the link didn’t work.

The Sony sensors can be a bit hit and miss with the amp glow, the 178 and 183 are good examples where it’s a bit shocking with their starburst pattern. They also have a nasty habit of recalibrating at power on, so your bias frames from one night to the next are not the same, which isn’t good for master darks.

From reading the specs, I’d love one to try out, looks like an excellent DSLR replacement for colour imaging at a dark site...
