Here is the Omega Nebula using the L-eNhance Filter.

This object sits LOW in the sky from my latitude (43 N), and shooting to the south means right into the light dome of the city.

This image includes just 16 x 4-minutes under moonlit sky! (Have I provided enough excuses) ;)

Needless to say, a challenging target from my backyard - yet I just can't get enough of it. I feel like I've been shooting the Swan/Omega all summer.

The Optolong L-eNhance filter (dual bandpass) has exceeded my expectations, and these multi-line filters are a godsend for imagers like me. I realllly worked on this one to get the stars "right" - could have spent another 4 hours easy. lol.

Hope you like it!
