FMC coating; SV407 super wide binocular is the real FMC objective lens; the center is clean and sharp; you can observe entire constellations and star fields and the stars are brighter and clearer more than just with the naked eye
Wide angle; a 26-degree view of the field is like walking in space; looking through SV407 binoculars shows you complete constellations with a 26°field of view; you can observe not just the main stars in a constellation but many you have probably never even seen before
The long depth of field design; it almost seems as if you are standing on a very high mountain in absolute darkness; from the recent focus distance to infinity; no need to twist the eyepiece frame to focus and operation portable
SVBONY moon filter is a good all rounder filter suited to many applications;including the observation of the moon and planets;a broad spectrum of light transmission means it does not block as much as a deep sky filter
The filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space
