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
NGC 7822
This image was produced from data gathered over 3 part nights of acquisition after viewing, and being inspired by, the same target on a well known YouTuber’s personal website. The processing done in PixInsight benefitted from the use of Russell Croman’s tools and also through the use of Generalised Hyperbolic Stretch. It has taken me a little while to become used to GHS but the work has been worth it. I feel like I know what I am doing now with GHS. By Barry Trudgian.
