Who has brought us the best M27? Pick your favorite from the following:


When I captured this, I hadn't yet received the extension rings to position my camera the proper distance from the coma corrector, so this isn't the best image I would have liked to submit. This has been one of the wettest July's in recent memory here, so there've been precious few opportunities to snag photons, and none coming up before the contest deadline, so I'll go with what I have.

M27 was my test subject for learning to guide and take exposures over 1 minute. Needless to say I had a lot of bad frames. These were the best of the lot. This was also my first time using PixInsight.
