Moving over to 2" filters so as much as I love these little guys, they gotta go.
ZWO NEW LRGB mounted filter set. These are the redesigned version designed to get the most out of the ASI 1600 camera. New from Bintel $270 - asking $200
Astrodon HA3_27R 3nm Ha filter - if you REALLY into narrow band this is amazing. You'd pay $8-900 to import this from the US today - asking $550
