Hi All -
My main interest is Photometry but that does not mean I don't care about astrophotography.
Best I can tell, the tolerances for UBVRI filters are tighter in the given spectra than LRGB filters.
The traditional Chroma Blue filter from the LRGB set begins at a wavelength of about 415 and ends about 500.
The traditional Chroma B Filer from the UBVRI set begins at a wavelength of about 400 and ends about 500.
The traditional Chroma Red filter from the LRGB set begins at a wavelength of about 575 and ends about 725.
The traditional Chroma R Filer from the UBVRI set begins at a wavelength of about 525 and ends about 725.
The examples above are not exact, but close approximations base on the Chroma graphs.
The actual graphs can be seen here: https://www.chroma.c...my-applications
It would seem to me this means that I could use the UBVRI set for imaging (as desired) without the need to buy a whole new set (and filter wheel) for LRGB filters.
I would not however,\want to use LRGB for photometry as you would "lose" the lower band of certain wavelengths.
Is that reasonable?
