Description

The Jellyfish Nebula, with the "double tube" technique. APO 130/900 with SBIG 11000M in Ha, and on the same time Baker 200 mm f/2,3 with Canon 350 baader modified. 15x600" in Ha, 25x300" in color, because of passing clouds. Italian Appennini, Bortle 3+, SQM 21,0, really high humidity. The Baker went a bit defocused, and at f2 it is a tragedy. Images B and C are color and Ha alone. Combined and color images are cropped to avoid the borders of defocused Baker.
