Antlia ALP-T Dual Band Filters

Antlia ALP-T dual band filters pass two emission lines at once, which makes narrowband imaging possible with a one-shot color camera. The Ha/OIII filters target emission nebulae, while the SII/Hb filters capture the other two lines for a fuller color palette.

Options include 5nm versions, a 5nm Ha/OIII Highspeed model for fast optics, and tighter 3nm Ha&OIII and 3.5nm SII&Hb filters for stronger light pollution. Matched 2" filter sets combine both pairs.
