LRGB Astrophotography Filters

These new ZWO LRGB Filters have good performance in transmission, also it has good coating, good colour separation. They are designed to approximately equalize the flux of CMOS camera sensor. Better transmission, Better coating, Better color separation Specifications Model 1.25" (ZWO-LRGB1.25) 2" (ZWO-LRGB2) Size 1.25 inches 2 inches Thickness 5mm + 2.5mm(thread) 5mm + 2.5mm(thread) Thread M28.5*0.6 M48*0.75 Other Details Fine-optically polished to ensure accurate 1/4 wavefront more than 92% transmission at passband Infrared wavelength 700-1100nm cut-off Precision off-band blocking Multi-layers anti-reflection coating Small spectral “gap” to minimize effect of light pollution More parfocal – thickness 1.9+/-0.03 mm

The ZWO LRGB filters have better transmission, better coating, and better colour separation. Description Overview Name: ZWO LRGB 31/36mm filter(4 filters) Fine-optically polished to ensure accurate 1/4 wavefront more than 92% transmission at passband Infrared wavelength 700-1100nm cut-off Precision off-band blocking Multi-layers anti-reflection coating Small spectral “gap” to minimize effect of light pollution More parfocal – thickness 2mm Size: 31/36mm

Optolong LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colours. The LRGB filter set divides the spectrum into its components red, green, blue and luminance. Description OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural colour imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves colour balance and separation. RGB, parfocal 1:1:1 Create images in their true original colours showing a wealth of natural detail Steep bandpass filters to eliminate UV...

The Antlia LRGB-V Pro series filters are designed for monochrome cameras that use both CCD and CMOS sensors. Suitable sensors include KAF/KAI sensors, Sony IMX sensors, GSENSE and other sensor manufacturers. The LRGB-V Pro set is designed to approximately equalize the RGB response from the flux of red-sensitive CCD detectors. Description The result is that you achieve 1:1:1 equalized RGB exposures with the benefit of simplified post processing and reduced imaging time. New LRGB-V Pro series filters feature a carefully designed spectral gap between the green and red channels to minimize the effect of light pollution and to provide high...
