Here’s my latest image of the Sunflower Galaxy. This was taken over two nights earlier this week during a small stretch of clear skies and is the second target with my new ONTC 10” f/4 scope. The larger aperture sure helps with resolving the knots in the spiral arms compared to my older TMB130 image.
The Sunflower Galaxy, M63, is a spiral galaxy in Canes Venatici and lies some 30 million light years away. It is a flocculent (meaning fluffy) spiral galaxy which has no defined spiral arms, in contrast to grand design spiral galaxies like M81 or M101. Self propagating star formation is one explanation for the structure of these galaxies.
