Optolong LRGB Filter Kit 2" Mounted (OPT-LRGB-KIT-2)

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 and IR interference
• Include Luminance (UV/IR Cut), Red, Green, and Blue filters to reproduce the star's colour

Coating Technology

• Multi-layers anti-reflection coating
• Non-cementing optical substrate coating
• Optolong L-Pro filter adopts precision coating based on Ion-assisted deposition coating technology for durability and resistance to scratching, as well as stability on CWL(central wavelength) no deviation affected by temperature change.
• Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and Optical density of off-band.
