NGC4565 / Caldwell 38 Spindle Galaxy

By |2019-04-01T16:19:57+00:001 April 2019|Categories: Caldwell, Galaxy, News|

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.

18 panels were just enough. This is 3000 pixels reduce from the original 5000.
