Cheers for your reply. It’s a fair point about the duo/tribands. I have the STC Duo Narrowband myself and have been seeing the results of the Radian Triad Quad Narrowband (quite pricey) on the CN forum.
In no particular order, I am looking at :-
- improved resolution & detail
- higher sensitivity (bypassing the Bayer filter as such the preference of monochrome)
- better control of different wavelengths - even with the Duo/Tri/Quad NarrowBands with OSC, exposure time is equal for each as opposed to mono.
- something different from just red Ha - i.e. getting into false colour. Even with the aforementioned narrowbands, colours are still mostly red with OSC. It seems remapping OSC colours using some kinda Hubble Palatte Synthetisers aren’t so easy too.
Here is a sample I’ve taken with my STC DuoNarrowband with my cooled Astro A7S with my Pentax 125SDP. Pardon the poor tracking in this particular case.
P.S. seems in typing this I feel I’ve talked myself more into the mono path.
