Description

I've been trying to get a wide field image of the Heart and Soul nebulae along with the Double Cluster on and off for the past few months without much luck. Lots of OSC subs going into the trash thanks to haze, occasional clouds, and light pollution gradients I haven't been able to remove in post-processing. Finally was able to gather some passable H-alpha data earlier this month. I still want to add more data but liked this image enough to post as a reminder to myself to keep at this target.

Heart Nebula (IC 1805), Soul Nebula (IC 1848), and the Double Cluster (NGC 869 and NGC 884) imaged with Nikon 75-1500 mm Series E zoom lens at 75mm and F/4, Optolong 12 nm H-alpha Filter, and full-spectrum modified Nikon D5300 mounted on a Celestron AVX mount. Stacked using PI for a total integration time of ~1hr using 34x 90 sec subs at ISO 1600. Subtracted darks, bias, and flats. Processed in Pixinsight: Cropped, split into RGB channels with Channel extraction then worked with only the red channel going forward, gradient removal with ABE, stretched using Histogram Transformation Tool, Curves Transformation, ACDR noise reduction.
