More information

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.

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.
