More information

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.

RGB, parfocal:1:1:1
Creat images in their true original colors 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 color;

Optolong SHO6.5nm 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 .

Extra narrowband SIICCD 6.5nm filter (Sulful II for CCD) is designed for nebula observation allowing 12nm bandwidth of light centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow)

H-Alpha 7nm filter is the popular narrowband filter allowing 7nm bandwidth of light centered on a wavelength of 656nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow). Better choice of narrowband H-alpha astrophotography filter for highest contrast and revealing subtle nebula details.

Extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).

OIII emits 495.9nm and 500.7nm and it is a blue-green colored filter. Many of images of planetary nebula and supernova remnants are taken only with H-alpha and OIII filters. They show great structural details, but have natural colors, looking like an RGB image.

Features:

Give you higher contrast and greater detailed viewing;

Decrease background noise and improve the contrast of objects;

Increase the faint nebula signal and make it to be brightness;

With narrow band filters kit, you are able to process a hubble image;

Through the optimization of the substrate and upgrading of coating technology, significantly improved the halo around the stars, especially in O3.
