SVBONY SV115 Telescope Filter O-III Filter with UHC Filter

SV115 O-III telescope filter suitable for visual observation on most emission nebulae, planetary nebulae and supernova remnants. Bright nebulae such as the M42 Orion Nebula can be viewed more clearly using SV115 narrowband filter in conditions of severe light pollution.If you're not sure if a light pollution filter will benefit you or not (and it probably will), this SVBONY UHC Filter is a relatively inexpensive way to find out. Best of all, once you have it you'll probably feel no need to pick up a pricier one since this one will likely meet all of your needs.

• The 1.25" O-III filter useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming. Allowing just for the Double Ionized Oxygen lines between 495.9nm to 500.7nm to pass through at 90%
• Astrophotographic;The filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; 1.25" filter allows high-contrast imaging even in areas with strong light pollution
• The filter made from high-grade glass with dichroic interference and antireflection coatings;not only useful at light-polluted sites; the contrast is also increased at dark sky sites;it can be used with all 1.25" eyepieces
• UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light
• Sky background is darker;and contrast of emission nebulae are noticeably improved;the perfect filter for viewing nebula from light polluted skies;or for boosting the contrast of nebula from dark sky sites
