Here's another object from the ongoing project to find planetary nebula halos. Abell 42 is already one of the faintest Abell planetary nebulae and of course the halo is even fainter. I wanted to get more data to flesh the image out a bit but the weather has been uncooperative lately to say the least.
Anyway here it is. Not what you would call spectacular.
Cheers
Steve
