Good to see Celestron offering this filter. One of the big issues with ultra fast scopes like the RASA and HyperStar conversions, is the problems that emerge using standard filters, particularly narrowband ones and LPs, as the fast ratio light angles can be somewhat blocked by standard filters and can slew spectrum ranges outside the norms.
