Description

No fields for readout mode, so here's the additional info:
Ha: Mode 0, Gain 26, Offset 10
R, G, B, Mode 3, Gain 0, Offset 20

Mode 3 is Extended Full Well with a well depth of over 80k electrons at Gain 0. I used this to see If I could tame the mighty Alnitak and avoid saturation. Worked.
