Product Description
Brief Introcuction of
Astronomical Filter
LRGB + SHO 7nm
Optolong
LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into its components Red, Green, Blue and Luminance. OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance and separation.
and the
SHO - 7nm filter kit includes SII6.5nm, H-Alpha7nm, and OIII6.5nm narrow-band filters, generally working with astronomical monochrome cooling CCD and modified DSLR imaging in each single-channel . Corresponding with RGB channel (Ha, OIII, SII), photographers can process Hubble images by astronomical post processing software .
LRGB + SHO Kit is not limited to photographing planets, it can also be used to photograph galaxies, star clusters and nebulae in the deep space.
