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
Due to its ability to produce exceptionally 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
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
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
1.25 inches CLS filter; 90% transmission of main nebula emission lines;such as Ha 656nm; OIII 496nm;500nm;SII672nm and H-beta 486nm
