Hartl-Dengl-Weinberger 2 is a faint and old planetary nebula in Cassiopeia. It is also known as Sharpless-200. It has a very faint extended Halo which is nearly 40' making one of the larger planetary nebulae. The halo extends into a small open cluster, Trumpler 3. Battling a near full moon, light pollution, poor seeing, wind and clouds, it was a challenge to pull this one from the muck. It required eight hours of 30 minute Ha subs and 6hours of OIII over four evenings.
