Antlia Triband RGB Ultra Filter II – 2” Mounted

Description

Antlia Triband RGB Ultra Filter II

The Antlia Triband RGB Ultra Filter II adds the H-Beta 486.1nm line to the Triband RGB Ultra, enhancing its ability to capture finer details of nebulae. It is designed for light pollution suppression for OSC and Mono cameras. The spectral design selected the most substantial information in the RGB bands, which makes Antlia Triband RGB Ultra Filter II possible to shoot over 90% of deep sky objects, in addition to its excellent performance on emission nebula, different from other ultra-narrowband filters, it is able to capture galaxies, reflection nebulae, and star clusters from a Bortle 8 location to Bortle 1 while presenting more balanced RGB colors in your images. Also, it has a broad bandpass designed to cope with faster optics up to the f/2 focal ratio.

Application and Performance:

² It is workable to shoot galaxies, reflection nebulae and star clusters.

² Refined coating process makes the Triband RGB Ultra filters II with excellent halo suppression and improved signal-to-noise performance.

² It has been specifically designed for balanced color transmission using Antlia’s experience in spectrum design.

² The balanced transmission allows the minimal color cast to broadband emission objects such as stars, galaxies, and globular clusters.

² The Triband RGB Ultra II can be used with nearly all systems as fast as f/2 with minimal loss of efficiency or shifts in spectral response.
