Description

A rework of some data from last year, where I was struggling in image processing with different problems. It's as Messier 3 widefield image, made with my good old Skywatcher ED100 refractor and the TS 0.79x 3" Reducer. The reducer was not designed fo a this telescope. This and the extrem Sahara dust during image capturing caused some artefacts around bright stars. The image is the best result after testing a few techniques in image processing. But it's impossible to completely get rid of all halos.
Nevertheless the result is quite good for me, especially when we think about the telescope which was used.

115 x 4 minutes, ISO 160 with my cooled EOS 80d CDS. 25 Flats, 64 Bias frames. All processing was done in PixInsight only a small image enhancement was done finally in Lightroom.
