During partially hazy conditions, a William Optics Megrez 90 was fitted with an Altair Herschel Wedge and mounted on an iOptron CEM26 mount and an Apollo-M Mini camera used to take a 2 minute SER of the Sun using Astro DMx Capture. Some 20% of 8,193 frames were then stacked in Autostakkert!4, wavelet processed in Registax and finished in Pixinsight's solar toolbox where false colour was applied. The arrangement allowed for a full disk image to be taken and a crop was then made to show the sunspot detail which was today confined to one quadrant of the Sun.
