Description

This is my second attempt at an image of the Pleiades (M45) with the new APO refractor setup. This image has ~4 hrs integration time (about 2x my previous attempt) captured over three nights (December 5, 10, and 11, 2017). I tried to combine additional data sets but have had problems with the resulting stacks. Will keep working on this one, but this is a bit better than the first attempt.

M45 imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer and Nikon D750. Stacked using DSS for a total integration time of ~4 hours using 120 sec subs at ISO 200. Subtracted darks, bias, and flats. Processed in Pixinsight: Cropped, gradient removal with DBE, Background Neutralization, Color Calibration, SCNR, stretched using Histogram Transformation Tool, Curves Transformation, HDR Multiscale Transform, ACDNR noise reduction, Color Calibration.
