|The fascinating spiral galaxy Messier 64 (Black Eye Galaxy, Evil Eye Galaxy, NGC 4826) in the constellation Coma
Berenices on April 22 / 23, 2020 and on April 23 / 24, 2020. Messier 64 is a Type II Seyfert Galaxy, showing narrow emission lines in its spectrum. A dark band of absorbing
dust in front of the galaxy's bright nucleus gave rise to its nicknames of the "Black Eye" or "Evil Eye" galaxy. A possible formation scenario of the dust cloud is a merger
with a small dust-rich galaxy a billion years ago. Messier 64 is about 17-24 million light-years from Earth
and was discovered by British astronomer Edward Pigott in 1779 (published two years later), and independently by Johann Elert Bode in the same year, as well as by Charles
Messier in 1780 (source: Wikipedia).
Fourty 3 minute exposures at ISO 800 were added for this shot with the DeepSkyStacker software (resulting in a 2 hour exposure) and the final image processing was done in Photoshop.
