Neighborhood: Oak Cliff. Just outside of Downtown Dallas Texas. The worst possible place to view the stars in my opinion. Equipment: Orion XT6i doing visual astronomy. We couldn't see much in all honesty, Because the sky was like looking at the stars through an empty plastic milk jug. After viewing the Orion Nebula for a few minutes, I remembered having my CLS Filter. Screwed it on and it made substantial difference! The Orion Nebula had a lot more contrast and detail. It was visibility much more enjoyable to observe. After that we looked at a few double stars and Pleiades which looked nice. Can't comment on Astrophotography, but for visual viewing, in the described sky, it made our night go from "hohum" to "Oh wow! Look at that!" Review: Good for price - I like it it really cut out the light pollution ## Features - 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 - Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass band and Optical density of off-band - 90% transmission of main nebula emission lines;such as Ha 656nm;OIII 496nm;500nm;SII672nm and H-beta 486nm - 0.1% transmission of off-band;specifically the major emission lines of artificial light pollution;such as Na 589nm;Hg 435nmand 578nm - Suitable for color CCD cameras and unmodified DSLR Urban optical filter can effectively suppress urban harmful light and improve the contrast of shooting target ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079BWDRFC | | Audio Recording | No | | Best Sellers Rank | #24 in Telescope Filters | | Brand | SVBONY | | Coating Description | Multi Coating | | Compatible Devices | color CCD cameras, unmodified DSLR cameras, visual use | | Customer Reviews | 4.4 4.4 out of 5 stars (309) | | Enclosure Material | Optical Glass | | Has Self-Timer | No | | Item Dimensions L x W | 2"L x 2"W | | Manufacturer | SVBONY | | Media Type | ProductImage | | Photo Filter Size | 48.5 Millimeters | | Screen Size | 2 Inches | | Special Effect | Enhancing | | Thread Size | 48.5 Millimeters | | UPC | 609378745584 | | Viewfinder Type | optical viewfinder | | Warranty Description | We provide 1 year warranty for SVBONY telescope accessories and 30 days no reason to return.

The filters "ears" at the 4 and 8 o'clock postion that hold the filter in the camera body often need some "adjustment" to achieve a secure fit. **Q: Will this fit the Canon 5DsR camera body?** A: Dear customer , Thanks for your contact.
