Hello everyone, I know that high-speed optimized narrowband filters are often recommended for RASA and HyperStar systems because of the bandpass shift. What about LRGB filters at f/2.2? Are standard LRGB filters sufficient, or is it worth investing in high-speed optimized LRGB filters as well? Thanks in advance! Clear skies!

LRGB filters have very wide bandpasses, typically about 100nm for RGB and huge for L, they won’t be effected.
