Description

Since I took the "Propeller" nebula last year with the RASA and the Z61 I could not resist to combine the 2 images into 1. That was quite an experiment, was fun though. Here the result, thought that it came out nice enough to post, even with the problems mentioned in the sole 2021 image. See version D for a comparison.
One interesting part: the DWB naming of the area. See http://www.distant-lights.at/simeis57_hubble-2015_08_31.htm, which I think summarizes it the best.
