Baader 6.5nm f/2 mounted 2" CMOS filters

DESCRIPTION
This Baader Ultra High Speed 2" mounted filter set is designed for extremely fast optics (≥ f/3.4), such as Celestron's RASA astrographs. Each filter provides strong contrast and balanced exposure times for all channels. Equipped with Reflex-Blocker™ and Life-Coat™ coatings, they offer minimal halos and maximum durability. Every filter is individually sealed, with blackened edges and a telescope-facing indicator.
