Melotte 15

An artistic edit of our first narrowband image, the heart of the heart nebula, shot in h-alpha. This is 39x 600 second exposures shot with an ASI1600mm Pro and Celestron Edge HD 9.25" Telescope (w/ 0.7x reducer) on a Celestron CGX-L Mount. We're waiting for our Oiii filter to arrive so I figured I'd play around with the data we have so far to. Probably will add more to this to reduce noise, this is a "starless" (although not totally, lol) version.

Heart Nebula

I've been working on this shot for a few weeks now, the heart nebula is a tough one to image with a DSLR, signal is faint and any light pollution makes it very tough without narrowband filters. I recently got an Optolong L-enhance filter which has made doing narrowband a lot easier with my modified D5300. This is 50 x 10minute exposures shot with a full-spectrum D5300 and Astrotech AT65EDQ on a Sirius EQ-G mount.
