Thanks Malcolm.
I'm going out again tonight to chase a few things down so I've put M46 down as I'm starting somewhere close to that area. I'll see if I can fit NGC 2818 in again, not sure I'll get it but I'll be swinging back that way later in the night. Should have time in the morning to put another report up on the board. Really enjoying hunting for PNs at the moment and it is interesting to find that they are all slightly different. Makes the mystery of what you will see all the more exciting.
