I've been working to get my backlog of images processed since comet Leonard has moved into the evening sky and is too low to capture from home. The comet has actually brightened quite a bit since passing around the sun. Our neighbors in the southern hemisphere are now getting some really fantastic views and images of Leonard.
This image is Abell 85/CTB 1, which is a nearby supernova remnant with an apparent diameter of about a half a degree. For perspective that is the same size as a Full Moon. Originally CTB1 was thought to be a planetary nebula, so Abell included it in his catalog of planetary nebulae as Abell 85. This is a full SHO (Hubble Palette), hence the golden color throughout.
