Filters/Exposures:
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), and processed.
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.
Date/Time:
Ha and SII taken 16, 17, and 18 June 2012;   OIII taken 22, 23, and 24 August 2012
Comments:
The filter assignments used for this image 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.
