Set of two 2" mounted filters (M48x0.75 thread)
Antlia ALP-T Dual Band 3nm Ha&OIII filter: Dual band filter with a very narrow passband of 3nm in OIII and H-alpha to achieve a higher signal-to-noise ratio.
Antlia ALP-T Dual Band 3.5nm SII&Hb filter: Dual band filter with a very narrow pass band of 3.5nm H-beta and S-II. This filter is ideal for increasing contrast of nebulae that emit in the sulfur and H-beta range using OSC. It provides additional feature separation and isolation in Hb areas.
The combination of these two dual band Ha&OIII and SII&H-beta filters allows extreme narrow-band images with OSC cameras by capturing the spectral data from 4 channels i.e. Ha/OIII/SII/Hb. The spectrum of these four channels can be separated and recombined into various color palettes in your post-processing. The resulting images can be used for luminance contrast enhancement of traditional RGB-balanced images or the creation of images in various popular false-color palettes such as H-O-Hb, S-H-O, H-S-OHb, H-O-O, etc.
