Managed a quick imaging session between clouds over lunch. Not a lot to see, but at least there is a spot visible, plus a hint of something on the limb nearby.

I managed to tease out some proms using the partial inversion look-up table I usually reserve for H-alpha.

Maybe I can at least observe some H-alpha during the tea break
