Due to my less than ideal local horizon, long imaging sessions are pretty much out of the question. The maximum I can achieve on any one night is about 90 minutes on a given object. Over three nights, I was able to capture 2.4 hours of data on the North America Nebula. To get a really decent image requires about double that integration time, and I'm hoping to capture more as the weather permits. Here are tow images so far, one in the obligatory H II red, and the other a fanciful pseudo-Hubble palette. The Hubble mix (courtesy Siril) rather blew the highlights and added lots of noise for some reason, but it's an interesting contrast to the original image.
The trials, tribulations and small triumphs of a Charlotte, NC astronomer imaging under Bortle 8/9 skies.
