Taken on 10th December 2012; 18x10 min H-alpha and 12x10 min each for OIII & SII, so 7 hours of data (imaging from 8pm-3am). I did this target last December as well - took me 3 weeks then to get the data across all the filters for a 4 panel mosaic - one year on I get the lot in a single frame on a single night!
