Description

M101 in Ha + RGB, taken with my wide field telescope that, is installed in a remote observatory in Spain, over a period of 3 nights in April. My intention was to highlight the Ha regions of the Pinwheel Galaxy. I was positively surprised to see that Hs regions appeared also in other galaxies such as NGC5474 and UGC8837.

Ha: 33 x 600 sec
RGB: 50 x 120 sec (each channel)
