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.
