IC1805 Heart Nebula in Narrowband

Second version with less stars.

Zoomed in to image center.

Notes: This was an imaging run that took three nights to complete with 6 hours per filter and 30 minute subs for a total of 18 hours imaging. I’ve never imaged that long on one object before but I think the effort was worth it. I used the Hubble Palatte with SII as Red, Ha as Green and OIII as blue.

About Richard Murray

I've been interested in astrophotography for some time now and more recently began writing science fiction. Half a million words plus later, I continue to write every day. I share some of the things I learned along the way as well as some of my writing, plus an occasional astrophoto I’ve taken just for fun on my blog site Fictional Astronomer at www.rmurrr.com .
