Mixed data sets captured over 4 nights with Voyager. The small chip in the ASI533 requires a short focal length to just fit in M31. Using the RedCat 51 at 250mm served the image well here, although there can be a little loss of absolute detail when imaging at this focal length and pixel scale.
Guiding was done using a small (32mm) guide scope sat inside the RedCat "handle" alongside a ZWO 120MM-mini. The RedCat also has the DSD3 auto focuser installed.
Stacked and calibrated in APP, then processed in PixInsight.
