North American Nebula Bi-Color (Ha, Oiii)
Finally took the plunge to a dedicated cooled CMOS astrophotography camera and couldn't be more thrilled with this first photo. Narrowband imaging and cooled sensors completely open up the door to whats possible through light pollution.
Here's the North American Nebula and most of the Pelican Nebula (NGC7000 and IC5070) in the Constellation Cygnus from the front porch of our house in both the Hubble color palette and more natural HOS palette (second photo). This is a large area of emission nebulosity stretching about 2.5 degrees east of the prominent star Deneb. This area is highly studied due to its large amount of active star formation, and named for its obvious relation to the North American Continent and Pelican, althought I tend to see a hand trying to grab a rabbit who's smiling since he just evaded capture π. Total integration time of about 7.5hrs taken with a nearly full moon.
Image specs:
Zwo ASI294MC color camera, Meade 70mm Quadruplet APO, Skywatcher EQ6-R mount, Orion 50mm guidescope and Starshoot Autoguider.
30 x 400" Ha (red) Frames (3hrs,20min) Zwo 7nm ha filter.
30 Darks, 35 flats, 35 dark flats.
17 x 900" Oiii (blue) Frames (4hrs) Zwo 7nm oiii filter.
30 Darks, 40 flats, 40 dark flats.
Green channel synthesized using the LRGB layer tools in Startools.
Captured using APT, stacked in DSS, processed in Startools, final refinements in Lightroom CC.
