Notes I had imaged M65 as one of my first digital astrophotos back in April 2011. While the image was acceptable, I was very happy to have a chance to redo it with my better equipment and improved processing skills. As it happens, I'm very happy with this image, as I was able to capture some very good detail as well as some nice color with this newer image.
