This data set is from the first time capturing M45 with tracking and guiding. I posted it in November of 2022 on a FB group. Here I reprocessed it trying to bring out more nebulosity and surrounding dust using Bill Blanshan's color mask pixel math scripts.
Nikon D5500, Redcat51, SWSA tracker, Asiair plus, guided, Optolong L-pro filter, Bortle 5+.
ISO400, 90x180" subs, calibration frames; darks, flats, bias.
Stacked and processed in Pixinsight.
