SVBONY 1.25 inches 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 inches 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.

SVBONY 1.25 inches 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 all standard sized 1.25″ eyepieces and accessories;it is mounted in a nicely anodized housing and is threaded on both sides for stacking with other filters if necessary.
5. Standard filter thread for any 1.25” telescope eyepiece and other accessory;comes with a plastic box to keep it safe and clean when not in use.

SVBONY 1.25 inches UV/IR Cut Filter：

1. This UV/IR Cut off filter blocks undesirable ultraviolet and infrared rays that may interfere with obtaining the high contrast and high quality images possible with a digital sensor.
2. It serves as a permanent lens protector;digital imaging with DSLR cameras;CCD cameras;and modified WebCams;or telescope.
3. True optical quality glass substrate and coatings achieves greater detail;less chromatic aberration;more natural colors and finer color gradation.
4. Combine with any standard 1.25” filter threads for 1.25″ eyepieces and other accessories to deliver the sharpest images possible;reducing ghost images caused by IR radiation.
5. Comes with a plastic box to keep it safe and clean when not in use.
