Filter Optolong H-A7 (H-Alpha 7nm) round 31x2.0mm without frame

OTLOG-HA7-31C

152.85 161.11 -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.

Clip filter Optolong anti-light pollution filter UHC EOS APS-C

OTLOG-UHC-EOSCF

77.65 85.91 -8.26 VAT excl.

UHC (Ultra High Contrast) broadband filter designed to improve the visibility of deep sky objects, reducing the transmission of polluting wavelengths produced by artificial lights and the emission of neutral oxygen in our atmosphere (skyglow), being highly transparent in the main emission lines of nebulae.

OTLOG-SKYGLOW-125

26.41 34.67 -8.26 VAT excl.

SKYGLOW Optolong interference filters designed to enhance deep sky observation in moderate light pollution conditions, blocking most wavelengths (skyglow and artificial light) that cause light pollution. In contrast, their transmission is maximal for H α and β, significantly increasing the contrast of nebulae, galaxies and star clusters.
