This is straight RGB from 3x tubes that have inconsistent FoVs. Most of the data seems to be contributed from my Askar FRA600 and Canon Ra at 415mm (61x5m iso 1600), with some contribution from my heavily flexing Canon 100-400 and R6mkii at 540mm (61x5m iso 1600), with a big lift in the centre from my SVR90T and 6D at 600mm (44x5m).
This includes luminance data from the SBIG8300m and Orion ED80T at 384mm. Unfortunately, the focus on the SBIG was slipping during the evening, so while it punches deeper the Lum added some odd halos. I couldn't see it happening when I refocused, but it seems to have shifted a few times outside the usual thermal drift.
