Pacman LRGB

This is an image I took a few weeks ago, but only just got round to processing. I had an idea I could replace my Baader L filter with my Hutech LPF, however discovered it was not parfocal with the RGB filters. Ahh, I thought, focus offsets with my motor focusser. I determined the offset, but after the event noticed the focusser was slipping and not going back to the precise location. So the RGB is a bit rubbish, but binned so I thought it wouldn't matter too much. It does. Anyway, this is Lx7 300s, RGBx7 (150/105/135s) @ 2x2. Processing was a bit unusual, started with Nebulosity for the L, then discovered I had no 2x2 darks to make a bad pixel map so I went to DSS for the RGB. Thanks for looking.
