Description

I needed a lot more exposure time on this object, but trees in my yard block Cygnus pretty early in the evening this time of year. Hopefully next year!

The Clamshell Nebula is a large emission nebula about 2200 light-years from Earth, situated very close to the North America Nebula. The bright star 68 Cygni (bright blue star near center) is one of the stars that is ionizing surrounding hydrogen. I really like the surrounding dark nebulae (LDNs and LBNs) that show up in this widefield view.
