Sh2-54 In 'RGB-Like' Narrowband Mix

[Mike Lewis]

This target was mixed to bring out a more natural color style look while using narrowband data.

Sh2-54 (also called the Serpent Nebula) is a large emission nebula located roughly 6,000 light-years away in the constellation Serpens. It features active star formation, numerous protostars, and the open star cluster NGC 6604. It is part of a larger complex near the Eagle and Omega nebulae.

Oh man, I got back to California on Thursday and have been playing catch up ever since, I am sorry to have missed this beauty Mike as this one really is so striking. This could be one of the best images I have seen of SH2-54.

Thanks Jim! I tried to bring a somewhat different look to it, just as a change of pace. Glad you liked it!
