ngc 7000 north america nebula

Posted on

I decided to go after the north america nebula in cygnus last weekend. we had a single clear night, and I was able to pull in about 6 hours of data across Ha, Sii, and Oiii using the Explore Scientific ED102 APO and my ZWO ASI 1600MM Pro camera. It has still been quite warm in the evenings, so I’ve had cooling turned down only to -15c rather than -20c.

This target would make a nice mosaic candidate given its size, but I fit what I could with this focal length and camera pairing.

See below for the individual channels and balancing I used to combine into a SHO image in PixInsight.

From here, I mapped the data into RGB using R=Sii, G=Ha, B=Oiii. I applied some background neutralization and adjusted curves to produce the final image below.
