A Celestron 8" SCT was used with an SV305 camera at the Cassegrain focus. SE files of Jupiter and Saturn were captured using AstroDMx Capture for Windows. Stacking was done in Autostakkert!, wavelet processing was done in Registax 5.1 and post processing with the Gimp 2.10 and Affinity Photo.

A 6.3 focal reducer was fitted to the visual back of the SCT and 16 bit Tiff images were captured of M71, the Angelfish cluster, with matching dark frames.
The images were dark-frame corrected and stacked in Deep Sky Stacker and post processed in the Gimp 2.10.
