With the moon up, I put on the 7 Nm H alpha filter and had a go at imaging one of the newly discovered planetary nebulas from the UKST H Alpha survey.
Its called G307.3+02.0 and is VERY faint. I got it from this list
http://www.star.bris.ac.uk/halpha/PNCD/ascii/pnew.dat
Its 3x10 mins ISO 1600 with 10 inch f5.6 scope modded 350d
Not exactly blindingly bright lol.
