Description

First bi-channel NB image created with the ASI1600MM-Cool. This is a combination of Ha and OIII channels of a mere 50 minutes of integration each. There are 5x600s subs per channel acquired at gain setting 75 (~8400e- FWC, ~2.1e- RN).

This is a considerably weaker integration than I was originally aiming for...however, I am still a bit surprised at what is possible with this camera. For only 50 minutes of total integration a channel, I would have never expected to get such clean results. I am looking forward to having more clear sky time with this camera...so many amazing narrow band targets to explore!

Revision B: Local contrast enhancement to bring out details a bit more.
