The Chinese Dragon nebula and M101

AstroDMx Capture for Windows was used with a William Optics 80mm APO refractor with FR and Altair Hypercam 533C 14 bit OSC camera. 90 minutes worth of RAW 5 minute exposures were made of the Chinese Dragon nebula through an Altair HaOIII dualband filter, and just 35 minutes worth of 5 minute exposures of M101 through an LPRO-MAX filter. Stacking and part processing in PixInsight and post processing in Siril, GraXpert and Gimp 2.10 with Starnet++. The mount and focuser were controlled by AstroDMx Capture via an INDI server and autoguiding was by PHD2 via the INDI server.
