Filter Optolong H-A7 (H-Alpha 7nm) round 36x2,0mm without frame

OTLOG-HA7-36C

155.33 163.59 -8.26 VAT excl.

This narrow band filter offered by Telescopiomania is able to isolate the H-alpha line (656nm) of the visible spectrum, making it an effective barrier against stray light and is especially suitable for close study of the details of emission nebulae, providing high contrast and dramatically accentuating the details of this type of celestial objects.

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.

OTLOG-OIII18-125

64.43 72.69 -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.
