REVIEWS

LRGB filters is an essential accessory for obtaining color images with mono cameras. It can improve the contrast of the target area and highlight the details and layers. 
ToupTek Astro 36mm LRGB filters has a high transmittance of 95% and covers a rich spectral range. Through the exposure of the RGB three channels and post-synthesis, it can reveal a color-balanced, real and natural deep sky scene.

The L filter acts as a red-ultraviolet cut-off filter, passing visible light between 420nm-685nm with a high transmittance of 98%, enhancing the target contrast.

 

The R filter allows passage of red light from 590nm-700nm while maintaining maximum transmission of H-Alpha and [SII] emissions.

The G filter allows passage of light from 490nm-580nm, which is the first to cut off the emission lines of mercury, sodium, etc. near this spectrum.

The B filter allows the transmission of light in the 400nm-510nm band, which is more targeted at targets containing 486nm H-Beta rays (such as the Horsehead Nebula).
