## Description

desertcart.com : SVBONY Telescope Filter 2" CLS Broadband Filter, Reduce City Light Pollution Suitable for Deep Sky Visual Astronomical Photography : Electronics

Review: Realistic Expectations Folks! - Bortle 9+ skies. 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

## Questions & Answers

**Q: Inadequate responses still. eos 2000d has the same lens mount as others listed, why does it not fit?**
A: Not familiar with the specifics of the EOS 2000D body's internals but since these clip-in filters mount inside the camera body I would expect it to fit this ASP-C chip body, unless Canon did something surprising with this model.  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.
No,this can't fit.

### ⭐⭐⭐⭐ Budget friendly alternative
*by W***S on March 4, 2023*

Let face it we are not NASA. Don’t need to spend every dime on the top of the line things unless u want to for a status symbol . This will serve you well under moderate light pollution I live in a bottle 6 skies and it gets rid of almost all of it. If you haven’t tried svbony before give them a chance. For being a “budget” brand they are really cranking out some high quality things over there. Keep it up
