Greetings! Happy Belated Thanksgiving to my American friends!

 

I went out last week to image the Dolphin Nebula. I had a bit of a mishap, as it got so cold my laptop shut down in the middle of imaging. So, I had to reboot everything and start over. Luckily, I was able to add the 16 lights to the final stack. As a side note - I threw a couple of towels over the tote that my laptop sits in and put a couple of hand warmers on the computer. I had no more issues the rest of the evening.

Nice image.
However I think SH2-308 has been nicknamed Dolphin nebula

Edit: after some googling I found that this has also been named Dolphin, but I still thing SH2-308 resembles dolphin more.

This has been named the Shrimp, or the Firefox Nebula.

Yup, I saw that too. And, I agree SH2-308 looks more like a dolphin head.
