M101 – NGC5457
42x600s exposures of M101 captured on the 22 and 25 May, 2023, showing super nova 2023ixf. The image has been enhanced by addition of 95x600s exposures that I took in March 2020 of M101 using a Celestron Nightscape 10100 CCD camera but with the same scope and filter.
SN2023ixf was only taken from the 2023 exposures and cloned on to the full 137x600s image, at the linear phase of the processing so that the relative brightness of the supernova compared with foreground stars remains accurate. By Dean Ashton.

M3 – NGC5272
5hrs of total exposure using 10min subs. This was to get the very faint stars at the far periphery as well as the brighter centre that would require lower exposure. I used an extended full-well-depth mode on the camera from this to give a full well depth of 75,000e to prevent the core blowing out in the 600s exposures. by Dean Ashton
