Processed 3 different ways – give different results, not sure which I like best. Still too noisy – need many more exposures.
Interesting edge-on spiral galaxy in Coma Berenices, surprisingly large (14.9′ x 2′) but faint (9.60 but surface brightness 13.3). It is actually intrinsically more luminous than the Andromeda Galaxy. First seen by William Herschel in 1785. Also visible lower right is NGC 4562.
