Sh2-157 The LobsterClaw Nebula

[SiriusDoggy]

I was trying to force myself to have patience and stick to a single subject for an extended period of time. I usually get bored after a few nights of collecting data and decide I have enough and move on to something new. This time, I would say my patience has paid off. 3 nights of SII (Bortle 3), 4 nights of OIII (2 from my Bortle 8-9 backyard and 2 from a Bortle 3 dark site.) and 7 nights of Ha (6 from my Bortle 8-9 backyard and 1 from a Bortle 3 dark site.) and part of 1 night for the RGB data (Bortle 3) says I've finally broke that streak of getting bored. In fact, I plan on adding more data to this beautiful subject next year!

My longest project to date.

I've seen your results refine and improve dramatically over a few short years, Greg,
and you're really knocking 'em outta the park now!

Wow. I'm always amazed at all the interesting things up there. Well done. The time was worth it I think.
