Antlia Triband RGB Ultra Filter

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 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.

Quantum Efficiency

The quantum efficiency of the B channel in current CMOS sensors is often significantly lower than that of R and G channels. Antlia team was to provide a filter with a more realistic color balance for astrophotography from light polluted locations. The problem with the low blue wavelength efficiency becomes apparent when imaging reflection nebulae and blue stars. In CMOS sensors, the blue wavelengths also contain contribution from the stronger green spectrum, thereby affecting the balance of the blue colours. Many popular imaging objects contain reflection nebula with faint blue hues such the central part ofNGC2264. Therefore, we designed Antlia Triband RGB Ultra Filter that not only retains the HSO emission signal but alsoincreases the amount of Luminous flux of the blue B channel. By improving the blue wavelength transmission, the color of thephoto is better balanced and easier to manage in post processing.

Application and Performance:

  • It is workable to shoot galaxies, reflection nebulae and star clusters.
  • Refined coating process makes the Triband RGB Ultra filters with excellent halo suppression and improvedsignal-to-noise performance.
  • It has been specifically designed for balanced color transmission using Antlias experience in spectrum design.
  • The balanced transmission allows the minimal color cast to broadband emission objects such as stars, galaxies, andglobular clusters.
  • The Triband RGB Ultra can be used with nearly all systems as fast as f/2 with minimal loss of efficiency or shifts inspectral response.
  • When shooting LRGB with mono cameras, unless you are wanting to image LDN (dark nebulae) the Triband RGB Ultracan be used as a luminance filter replacement for objects such as nebulae and galaxies to improve contrast and signal tonoise ratio.
  • The Triband RGB Ultra is able to better isolate the H-alpha, O3 and blue spectrum from the background light pollution.
  • For visual use, Triband RGB Ultra filter ensures the high transmittance of the HSO emission line and can be used for observing deep-sky objects with large-diameter telescopes.
  • The filter provides excellent flexibility and compatibility with both OSC and Mono camera systems.
  • It facilitates the imaging of most astronomical objects using all optical configurations down to f/2 focal ratio.

TELESCOPIC EVENING

Together we will explore the world of telescopes and start from “zero” for beginners. We show the basics of how a telescope actually works, what differences there are and combine this with hands-on practice.
Everyone is welcome to bring their own instrument and get to know it better with our telescope experts, including Gerhard Rehak.
