Description

M101 imaged May 22, 2023 with Stellarvue SVX140T on Paramount MYT with ZWO ASI6200MC. 95 minute exposure in 1 minute subs.  Seeing was good and it was clear with no wind however transparency was poor due to smoke plumes from forest fires in western Canada being blown to New England  and being particularly concentrated over my imaging location. Post-processing was very lite and the only noise reduction used was despeckling in Photoshop Elements.  Stacking and calibration had been done in Siril.
