Fitro Optolong OIII 18nm 2" OIII 18nm 2" Fitro OIII 18nm 2"

OTLOG-OIII18-200

87.57 95.83 -8.26 VAT excl.

OIII narrow band filters are designed for the observation of nebulae emitting light of 500 nm wavelength. By selectively reducing transmission in the other wavelengths, they increase the contrast of nebulae and suppress the effects of street lighting, making them perfect for observing emission nebulae, planetary nebulae and supernova remnants.

Filter Optolong SII-CCD of 6.5nm 2"

OTLOG-SIICCD65-200

204.09 212.35 -8.26 VAT excl.

The 6.5 nm narrow band SII filter is designed for specific astrophotography at the 672 nm wavelength. It can be used in combination with the OIII and H-Alpha filters to create "Hubble-like" images. By selectively reducing the transmitted wavelengths, this filter suppresses the effects of street lighting.
