Description

Widefield shot with my 400mm Canon telephoto lens. Captured many little bonus galaxies! I've now imaged the Pinwheel with 3 different lens combos this spring, I think I like this take the best... while not quite as close and personal as the 2X teleconverter got me, I think the extra faint galaxies I captured made up for it, and maybe slightly sharper pic without the extra teleconverter. I did drizzle this image, and though I did downscale it afterward I left it slightly larger resolution than original.
