Description

This is an update of my first M51 with the same setup. A Nikon 1j5 mounted on a TS Photoline 102/714 with the corrector/reducer 0.79x for a pixel Scale of 0.85/arc/sec (more than the theoretical resoltion of the 102mm...).
I then add for testing a small amount of Halpha (1h) taken at sunrise with a Fuji GFX 50R and STC Duo-Narrowband without the reducer to compensate a part of the pixel scale difference.
