This is The Eastern Veil Nebula in Cygnus, also cataloged as NGC 6992. This is my first narrowband image, and at this point I am just learning the processing workflow. As with all narrowband composites, this is a false color image, with Hydrogen Alpha mapped to Red, Oxygen III mapped to Green, and Sulfur mapped to Blue.
The really crazy part of this is that most of the subframes were captured with a nearly full moon in the sky. The narrowband imaging process will change everything.
Image Info
This was taken with the newly upgraded travel astrophotography kit:
- Camera : ZWO ASI1600MM pro
- Lens: Canon 100-400 f/5.6L lens, set to 400mm
- Mount: iOptron SmartEQ Pro
- Hydrogen Alpha: 23 subframes of 120s = 46min integration
- Oxygen III: 24 subframes of 120s = 48min integration
- Sulfur: 10 subframes of 120s + 10 subframes of 300s = 70 min integration
- Total integration time: 184min = 3 hours, 4 min.
- Captured via ASIAir Pro automation
- Optical tracking via ASIAir automation, currently using ST4 mount control via the ASI120MM-S guide camera
- Separate channels aligned, stacked, and processed in Nebulosity
- Color integrated in PhotoShop
- Final processing in Aperture
