Description

First try at this target. It's very low in the sky (average altitude for this image ~28 degrees) so I usually wouldn't consider imaging it.

This is an unguided LRGB of M8. All subrames 120 seconds. L 36x120, RGB 5x120. I've never done such short exposures, but with my guide camera non-operational and a good mount that is well dialed-in I thought I'd take a shot at "pseudo lucky imaging" on this bright target. I would typically do no fewer than 600 second subframes, but this is an exceptional case and I'm pleasantly surprised with the results. This may make me rethink my approach to some targets in terms of total integration time.
