I am just getting started in doing photometry, so I am looking at this in a more long term view. I have been practicing for the last year using my current gear, that is only a L filter (LRGB) on my system. My question is pretty simple, should I go ahead an get a V filter to build a UVBRI chain or would it be more future use to go with the Sloan filter group r' to build toward ugriz group?
I plan to start simple, and move toward 3 filter group after at least a years worth of the single filter.
The Sloan and V filter for my 2" STL camera fw are pretty close in cost (close enough after all other costs).
