Observation Notes: is a very nice planetary to break up all these galaxies. It is bright, large and round at 100X. There are several dark areas in this nebula and they combine to look like this is a doughnut someone took a bite from. The UHC filter makes this effect more noticeable. There are three stars involved at 165X. .
