M64: A spiral galaxy in Canes Venatici with a prominent dust band near its core, approximately 17 million light years distant.

Significantly smaller than the Milky Way, M64 is unique in that its outer regions rotate in the opposite direction of the galaxy's core. This is suspected to be due to M64 absorbing a smaller galaxy perhaps a billion or more years ago.

I seem to have some issue going on with my color processing that is leading to my color-calibrated RGB images starting off with a sulfur-yellow hue. I'm able to correct it more or less but it is an issue I'd like to track down and at this point seems unique to the TEC, from which this is the second RGB image I've processed.
