Description

Yet another image of the Orion constellation in H-alpha. This time I imaged using my trusty old 50mm Nikon Series E lens which has served me well over many years...

Orion constellation imaged with Nikon 50 mm Series E at 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 ~2 hrs using 120 sec subs at ISO 800. 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.
