M51 - Itīs a composite of two images. First is a shot with Fuji Superia 200, 30 minutes exposure. Second was made on hypered Tech Pan, 40 minutes. Both images were stacked and enlarged in my darkroom. The print was scanned finally.
Scope was as usual a 12"/5,3 ATM-Newtonian. Guiding was done "by eye" with an off-axis-guider.
