Sell SVBONY Telescope Filter 1.25'' UHC+CLS+Moon+UV/IR Cut Filters Set for Astronomy Telescope Monocular best price

SVBONY 1.25" UHC+CLS+Moon+UV/IR Cut Filter Set Suitable For Ttelescope Observation Of Deep Sky Celestial Bodies. SVBONY 1.25 inch UHC Filter 1. UHC telescope filter was designed to improve the image contrast of observed objects. due to its ability to produce exceptionally sharp and clear images;this filter is considered one of the most popular astronomy accessories; it can be used not only for celestial observations but also for astrophotography. 2. This filter only passes the light around the 400nm line. It does not transmit the Ha and higher. Filter works great. 3. Optical glass lens; aluminum frame; significantly reduces light pollution; great for city and suburban observation. 4. Sharp and clear images;this UHC filter is considered one of the most popular astronomy accessories;it can be used not only for celestial observations but also for astrophotography. 5. Optical glass lens; aluminum frame; significantly reduces light pollution;great for city and suburban observation. SVBONY 1.25 inch CLS Filter 1. 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. 2. Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and Optical density of off band. 3. 90% transmission of main nebula emission lines;such as Ha 656nm;OIII 496nm;500nm;SII672nm and H-beta 486nm. 4. 0.1% transmission of off-band;specifically the major emission lines of artificial light pollution;such as Na 589nm;Hg 435nm and 578nm. 5. Suitable for color CCD cameras and unmodified DSLR Urban optical filter can effectively suppress urban harmful light and improve the contrast of shooting target. 6.CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollution. 7.Light pollution filter do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula. SVBONY 1.25 inch Moon Filter 1. 1.25" moon and skyglow filter 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. 2. Telescope eyepiece cutting light pollution;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. 3. The filter effectively filters out selective wavelengths of low pressure sodium and other man made sources typically used in street lighting;although it is not a nebula filter;it enhances the views of deep sky objects by increasing the contrast of these objects against the background sky. 4. Premium quality metal rim and thread with blue glass lens;the filter will fit
