This is a 3-tile mosaic comprised of eight 15-minute exposures each tile through Astrodon 5nm Ha, SII, and OIII filters, for a grand total of 72 exposures.  MaximDL was used to calibrate, align, stack, and stitch the exposures into 3 separate mosaics (ha, sii, and oiii).  These were then loaded into Photoshop CS6 where they were color combined (Hubble palette).
Shooting Location:
The Ha and SII exposures were taken from my back yard in the heavily light polluted city of Virginia Beach, VA.   The OIII filter requires a darker sky, so those 24 exposures were taken at Tree Farm Campground in Springfield, VT during the week following the Stellafane Convention.
Ha and SII taken 16, 17, and 18 June 2012;   OIII taken 22, 23, and 24 August 2012
The filter assignments used here was SII=Red, Ha=Green, and OIII=Blue.  This is the same filter combination used by the Hubble Space Telescope.  It gives a false-color image but greatly enhances the details.
