The one thats REALLY got my interest is this
Multi Emission Line
Narrowband filter for astro-imaging, similar to a UHC filter.
Thats like doing colour narrowband imaging in one shot. I guess it will be expensive, but its about time with so much one shot colour DSLR imaging about now, that they come up with a single filter that has , say a HA, O3 and maybe a S2 line, say 10 or so Nm wide each. Using such a filter for luminance on a monochrome CCD would be interesting too.
