I wanted to emphasize the Ha from the numerous star forming regions in M101, so I gathered some images using my NBZ filter and extracted the red channel & aded this to earlier unfiltered data. The original wideband image was captured on May 15th and 16th 2023. I added Ha data from several nights in June as well. I used a Celestron Edge HD 925 with a 0.7 reducer, an ASI 2600MC Pro. I managed to get 6 hours, 40 minutes total exposure time, with 80 x 300s subs, plus I added 8Hrs 20 minutes of Ha data. I processed it in Siril, Starnet and GIMP.
