This is my version of the North America Nebula - NGC 7000 in narrow band. I chose not to use the hubble pallette, but instead mapped the colors to Ha (red) SII (green) and OIII (blue) for the HSO pallette.
The image was taken with a Baader modified Canon T1i on a C925 EdgeHD hyperstar at f2.3. The total exposure time is 19 hr 10 min distributed in this way:
Ha: 8 hr 00 min (48 x 10 min) at ISO 1600
SII: 5 hr 50 min (35 x 10 min) at ISO 1600
OIII: 5 hr 20 min (32 x 10 min) at ISO 1600
It was captured with Sequence Generator Pro and processed entirely with Pixinsight.
Thanks for looking!
