Description

Imaged the Triangulum Galaxy (M33) using a WO GT81 refractor at F4.7 (382 mm focal length) and Flat6A II field flattener/0.8x reducer, IDAS LPS D1 Clip Filter, and full spectrum modified Nikon D5300.

Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Stacked 112 subs (180 sec at ISO 200) for a total integration time of ~5 hours. Post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT for noise reduction, Photometric Color Calibration, stretched using masked stretch, Curves Transformation, ACDNR for noise reduction, Morphological Transformation to shrink stars, Local histogram transform, and Color Saturation boost. with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, IDAS LPS D1 Clip Filter, and full spectrum modified Nikon D5300.
