In August 2023 a disastrous failure of the power supply in my observatory caused damage in several electrical devices, including the main camera, the Moravian G3-16200. It had to be sent to Moravian and as repair dragged on for many weeks, I decided to image with the 6"-Newton and the Touptek colour camera alone objects containing no or few emission nebulae, that I normally would not have chosen during late summer/early autumn.
Collecting frames with the fast colourcamera alone is comparatively easy. And as planning and realizing a mosaic in N.I.N.A. is a mere child's play, I ventured to create a mosaic of the great galaxy of Andromeda, M31.
Close inspection of the completed 6-panel-image showed I could better have planned an additional row of panels in the northeast-southwest-direction, because the spiral arms of M31 reach out even further. Also I underestimated the brightness of the core regions of M31 and M32, which are burned out after 5 minutes because of the Touptek's 14-bit.
Nevertheless I am quite satisfied with my first mosaic.
During the presentation of the image my astronomy-friends from the AAR identified in it the Mira-variable, by which Edwin Hubble (almost exactly 100 years earlier on a plate exposed with the 100-inch Hooker-telescope on Mount Wilson) proved that galaxies are independent systems far outside our local galaxy.
