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.

Yes that might work quite well.
I can't stack my filters as they are permanently mounted in the filterwheel, but I'd certainly be interested in hearing of your results

Very nice NIR image Rolf. I really like the colouring of this image and it makes a marked difference to many images one sees of this nebula. The video is superbly put together and would as Mike suggested provide some very interesting competition in the Malin awards if you were an Aussie.

Well done.

You can put another filter anywhere in the imaging train and leave your filter wheel as is. I have GSO extension tubes. They're threaded and can take any M42 filters.

Amazing captures Rolf.
