3nm dual band filters coming from Antlia

Two new filters are coming from Antlia that operate on a principle of selective transmission, allowing only the most scientifically significant wavelengths to reach your camera's sensor. We're talking about the 3nm Ha&OIII and the 3.5nm SII&H-beta filters - in a single filter.

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.

Dual band Ha and OIII and SII and H-beta filters

The advanced multi-coatings on Antlia ALP-T dual-band filters effectively isolate the red, Ha line, blue-green, OIII line, deep red SII, and the blue H-beta lines from emission nebulae, with almost total suppression of optical density (OD)4.5 on unwanted wavelengths from light pollution, moonlight, and airglow. The result is that both the ALP-T dual band Ha&OIII version and SII&Hb version create a superior signal-to-noise ratio and better contrast in your OSC images whether used in urban or rural areas, making them excellent choices for astrophotographers aiming to capture high-quality and more detailed celestial images.

When you buy 2 filters of Ha&OIII version and SII&H-beta version as a COMBO, you can get them at a cheaper price.
