I have collected some more data on the Pencil Nebula and reprocessed to produce a new version. I have added more Ha (now 3hrs) and Oiii (also now 3hrs), and included over an hour of Sii as well to assist balancing. Total integration time is now 7hrs and 15min. Still struggling to bring out those whispy filaments below the nebula but they are a bit better than the original version I think. That will have to do for now. If I get a night of really good seeing i may attempt to run more Oiii to boost the filament structure, and might get the 10" newt onto it at some point (remember this was taken through a 152mm f5 corrected Achro).
