At times of full moon like this, I have often wondered about the merits of using a UHC or multi-narrowband filter with a DSLR.
If I were to use a filter such as the Thousand Oaks LP4 (see
here), would this filter not allow me to collect Haplha on the red channel and Hbeta on the green/blue channel of my DSLR...? Meaning that I can use the full bayer matrix to collect meaningful data to boost a conventional OSC image?
Alternatively one could use a OIII filter (eg the Lumicon OIII shown
here) to collect OIII across both green and blue channels of a DSLR.
Am I missing something fundamental here or 1) would this be feasible, and 2) could it be done effectively under moonlight?
