Hi, Humayun, Slawomir, Michael, Steve,
Thanks for the nice words!
Just been going over the red spots mentioned by Greg and Slawomir. They are in every single red sub, just barely there but definite in the green subs, and totally absent from the blue subs. The filters are cycled R, G, B, R, G, B ... and across two nights, so it seems unlikely to be residual image "ghosting", because that would affect the first sub or two, but not subsequent ones. It's something that knows what filter is there. BUT, they don't look real. On the raw subs, they look like out of focus stars. I'm only using monochrome one-size-fits-all flats, so it's not a dodgy red flat. Some speck of grease on the red filter that spreads the light, but somehow has a hint in the same spot on the green filter ? Aaaugh! What a nightmare! Will have to look at images of other objects at the same spot.
Slawomir, there were FOUR satellites that went through the image. Most got automatically rejected. One incredibly bright, tumbling thing went through the very first sub just after Trish clicked "Expose". We saw it in the guide scope. That one missed the blender. I'll have a go at manually removing it from the particular sub.
Best,
Mike
