Messier 94 (also known as NGC 4736) is a spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781, and cataloged by Charles Messier two days later. The galaxy has two ring structures.

I captured it with mostly 30 second exposures except for the H-alpha which were 4 minutes each. Please subscribe to this YouTube Channel for more videos like this and follow me on Instagram: [ Ссылка ]
