Description

Continuing trials with my full spectrum modified Nikon D5300 DSLR, here is an image of the Orion constellation taken through a 12nm H-alpha filter on the evening of December 25, 2018. The overall integration time was only ~45 minutes, but I was thrilled to see I captured Banard's Loop (albiet faintly) and the Rosette Nebula for the first time from my light polluted neighborhood just north of downtown DC.

Orion constellation region imaged with Nikon 35 mm Series E zoom lens at F/4, Optolong 12 nm H-alpha Filter, and full-spectrum modified Nikon D5300 mounted on a Sky Watcher Star Adventurer mini equatorial mount. Stacked using PI for a total integration time of ~45 min using 60 sec subs at ISO 400. 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.
