Description

This image was taken during the 2019 annual Almost Heaven Star Party in West Virginia. The interesting thing here is that I managed to pull it together despite clouds rolling in prior to taking the blue subframes. The rest of the weekend was clouded out and living in  B6/7 at home I was forced to make due without any blue subframes. Luckily, I figured that data was recorded in the luminace master and that, in principle, L - R - G = B (roughly speaking of corse: Astrodon lum actually has more spectrum than the matching RGB filter bandpasses summed together due to some LP mitigation effort in the design of the Astrodon RGB filter pass bands). That said, I think it seems to have worked out alright.
