Optolong SHO-3nm Telescope Filter Kit - 2"
H-Alpha 3nm filter is the most popular narrowband filter allowing 3nm bandpass of light centered on a wavelength of 656nm. Extra narrowband SII-CCD 3nmĀ andĀ The OIII-CCD 3nm filtersĀ are designed for nebula observation allowing 3nm bandpassĀ of light centered on a wavelength of 500nmĀ (Oxygen-III) andĀ 672nm (Sulfur-II)Ā 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)
- For tricolor CCD astrophotography
- Narrowband imaging with SHO set can be done with the moon up in heavy light pollution, so your equipment is not sitting dormant for several weeks
- Hubble look of images can be made by the combination of H-alpha, OIII-CCD,Ā and SII-CCD, such as the famous āPillars of Creationā (M16 Eagle Nebula)
- H-alpha Filter - 2"
- SII Filter - 2"
- OIII Filter - 2"
