More About the Astronomik OIII 6 nm CCD Filter

For OIII emission line nebulae imaging from an ideally dark location or under heavily light polluted conditions, the Astronomik OIII CCD Filter offers complete impediment against mercury and sodium-vapor, the main causes of light pollution, as well as natural skyglow, and moonlight. The contrast between objects in the 501 nm doubly ionized oxygen line and the background is greatly enhanced. In addition, with this OIII 6 nm CCD Filter allows greenish and blueish targets to be photographed, considerably expanding your imaging potential.

This Astronomik OIII CCD Nikon XL Clip Filter incorporates a 6 nm narrow bandwidth with 96% typical transmission for a notable increase in contrast as all unwanted light from alternative wavelengths is blocked from UV up to IR. In comparison to the 12 nm OIII filter, this filter's smaller 6 nm FWHM (full width at half maximum) provides higher contrast gain. This results in an incredibly dark background.

Astronomik OIII Filters are the perfect choice for viewing under extremely light polluted conditions as well as for imaging faint targets in parts of the Milky with densely crowded stars. 6 nm FWHM is matched to provide superior performance with CCD and CMOS sensors with exceptionally low dark current! Furthermore, due to a new MFR coating technique applied to this filter, it can be used on all instruments up to f/4 without sacrificing efficiency.

Like all Astronomik filters, the OIII 6 nm CCD Nikon XL Full Frame Clip Filter is parfocal with all other Astronomik filters. Although its thickness is a miniscule 1 mm, this filter is still highly resistant to potential damage that scratching, aging, and high humidity can inflict. Diffraction limited to avoid lessening the optical performance of your telescope. Astronomik filters are delivered in a durable plastic storage container of superior quality.
