Me too! These narrowband filters also operate better at certain exit pupils so when considering 1.25" or 2" keep that in mind: many longer focal length (bigger exit pupil) eyepieces have a 2" diameter and you can always use a 2" filter with a 1.25" eyepiece (given the correct adapter) but not the other way around. I have a 2" Thousand Oaks O-III and H-Beta as well. Both seem to me to be much more useful under darker skies.
