Description

I was able to image Comet 46P/Wirtanen for a second time two nights after closest approach to Earth. The skyglow from the nearly full moon was really bad, and the images suffer accordingly. Still, fun to capture a few more images and it was interesting to see how far the comet progressed in the sky relative to the Pleiades over the course of a few nights. Imaged at both 50 mm and 75 mm focal lengths. This is the 50 mm focal length image.

Imaged with a Nikon D750, 50 mm Nikon Series E lens at at F/4. Exposures were 30s at ISO400. Stacked using DSS for a total integration time of 30 minutes (subtracted darks, bias, and flats). Processed in Pixinsight: Cropped, gradient removal with DBE, Background Neutralization, Color Calibration, stretched using Histogram Transformation Tool, Curves Transformation, and ACDNR noise reduction.
