Description

I thought I’d try this as an experiment really. I wanted to see if I could get an HaRGB image under city lights. And it’s actually very possible. The camera system used to acquire the RGB was a one shot color camera ZWO071 and only integrated 15 minutes with of exposures (60 seconds at zero gain) using the Celestron Hyperstar setup. The H-Alpha data was using a zwo 1600mm cool. About 1.5 hrs of HAlpha. 180seconds exposures at unity gain. All of this was shot in Los Angeles extremely light polluted skies.
