SVBONY Telescope Filter, 1.25 inches CLS Filter, Bundle with UHC Filter, and Universal Cell Phone Adapter Mount

SVBONY 1.25” moon and skylow is a multi-band pass filter transmitting a high percentage of light in the visual spectrum; the filter enhances contrast when observing brighter objects including the moon and planets It also will suppress sky glow from artificial lighting and background glow reflected when the moon is up Mild effect of darkening background of the night sky: So that the fainter objects is more clearly seen contrasted against the blackness of space Effectively filters out stray light: Filtering Selective wavelengths of low-pressure sodium and other man-made sources typically used in street lighting It enhances the views of deep-sky objects by increasing the contrast of these objects against the background sky While nebula filters transmit only a few select wavelengths corresponding to various atomic lines The filter transmits a large portion of the continuous spectrum while blocking a few select lines of the more common man-made light Neodymium provides a unique;selective;blocking feature in that this element greatly reduces glare without reducing important color and brightness variations

• CLS Filter; electron beam gun evaporation with Ion assisted deposition coating technology for durability and resistance to scratching;as well as stability on CWL (central wavelength) no deviation affected by temperature change
• CLS Filter; 0.1% transmission of off-band;specifically the major emission lines of artificial light pollution;such as Na 589nm;Hg 435nm and 578nm
• 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
• 55 to 100mm has been tested fits for iphone;iphone 5;5s;6;6 plus;7;7plus;Sony;Sony Xperia Z;Samsung Note;Samsung Galaxy S7;Galaxy 7;Galaxy 5;Galaxy Note 5;Samsung Note 4;ECT;Moto G5+ and many other brands
