Kent, et al; I am now confused. Kent's list includes lots of bright and famous objects. I thought that the reason for blinking PNs with the OIII was to...
Steve, My mistake. I thought you wanted some bright practice objects to get some experience with using the filter before going after the tougher ones. ...

Steve, The blinking technique should work wonderfully on MAG 13 PNe in the 5" - 10" size range when using a C-11. Just be sure to drape a dark cloth over your...
