M45 (the Pleiades) taken with the Passenger limited edition of the Vespera telescope with the IMX585 sensor. 3 hours 17 minutes of stacked 10-secoind frames. No filter. From a bortle 3.5 location. No moon. Post-processed the resulting TIFF with the following workflow:
initial auto-stretch in Siril as well as a removal of green noise.
then a number of edits in Affinity Photo including using the StarXtermintor and Topaz Anti-Noise plugins.
