Description

First narrowband attempt with mono camera. ASI294MM with Astrodon 5nm filters. Los Angeles area, Bortle 8, poor seeing, high humidity. Have only tried LRGB previously, but may be addicted to this NB thing.

Gain 120

Bin 4

20x 300 sec each Ha, SII

Only 6x 300 sec OIII before the AM marine layer rolled in

Pixelmath to combine, color calibration, Photometry, linear multi scale transform on masked background, then histogram transform, curves transform, morphological transform

Probably could have gone 600 sec without any overexposure issues as the histogram was only about 10% off the left side. Might try that next time.
