This is the star Sadr with a bunch of HA nebulosity around it. These are 1 min exposures with an L-enhance Optolong filter. The filter has 3 bandwidth's HA, HB, and OIII. Sadr is in the constellation Cygnus, in the eastern sky this time of year. Taken from my backyard in Gig Harbor WA, Enjoy!

Much better image than I've ever gotten of Sadr - one of my favorite stars in the sky! Great work!

This area has way more HA than I can fit in the Orion, that's why I asked about the focal reducer to get more of it. A search on the web didn't help at all either, lol. One thing about that filter I use is that it colors all the stars red, I don't know if I can correct that or not with the photo editing software I use??? 

Thanks, Jim!
