Cool - thanks. Maybe there's a way to cut bits into the Lum range >700nm by stacking filters.The Baader IR Pass filter kicks in at 650 and ramps up before 700. The baader UHC-S (nebula filter) has also peaks at 750, 850 and 950. Maybe stacking filters can get you close to the NIR R, G and B mapping. Will have to try.
