I decided to give this challenging planetary nebula in Hydra another try. I wanted to see if I could coax more details than a previous effort four year ago. This image was taken at a focal length of 4,196mm with a 6x8 arc minute field of view. A white dwarf star is in the center of it cast off stellar material that has expanded light years across.
