I shot M94 in May, 2010, at Chiefland Astronomy Village with the RC LRGB for about 5 hours. I was curious to see if I could record some of the outer spiral arms. You can see them best on the inverted image in the mosaic (right). Below is a link to Jay GaBany’s incredibly-deep image of M94 with a cool mouse-over showing superimposed Spitzer data (see below)!
