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
This filter only passes the light around the 400nm line. It does not transmit the Ha and higher. Filter works great
Optical glass lens; aluminum frame; significantly reduces light pollution; great for city and suburban observation
SV220 dual band filter can reduce the light pollution; enhance the contrast when imaging nebulae
For deep sky photography; use the dual-band filter to enable deep-sky photography in light-polluted cities or under a full moon
