Filters for astronomical telescopes

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.

Filters for astronomical telescopes

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.

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.

Solar Filters

The Baader digital solar filter with PHOTO-Film OD 3.8 has proven its effectiveness for many years, furthermore it allows shorter exposure times, mainly used for digital videography and lucky imaging technique, and thus almost "freezes" turbulences in the earth's atmosphere. It is NOT designed for observing the sun, only for digital imaging!
