Crafted with high-quality optical glass and a sturdy aluminum frame, it fits standard M48*0.75mm eyepieces and significantly darkens the sky background to reveal faint deep-sky objects. Ideal for city and suburban environments, this lightweight filter boosts your celestial observations and astrophotography by selectively transmitting key wavelengths while blocking urban light interference. ## Description Does a good job of cutting out light pollution. The sky is much more black than without it. However it does cause a halo. If you turn down the exposure it does go away or weakens up enough not to notice Gain new enlightenment into the night sky by making your darks darker and your blacks blacker. This filter is a necessary component of any well stocked filter collection. With it, one can find both wonder and splendor in the darkness amid the paradox of the night and the logic of the light Made of quality materials, lightweight, durable for years of use. This filter is perfect for observation of faint and low-contrast deep-sky objects. Standard M48*075mm thread, compatible for eyepieces of many telescopes. Significantly reduces light pollution and increase contrast, great for city and suburban observation. Nice accessory for astronomy lovers. Specification: Material: Optical glass lens, Aluminum Frame Barrel diameter: 2'' Thread: Standard M48*0.75mm Pls note: the filters of SVBONY are not designed for sun observation. Do not look at the sun with SVBONY filter. You would be HURT if you fail to observe the warning. Package Includes: SVBONY 2 inch UHC Filter Sturdy Plastic Case Review: I used the SVBONY 2-inch UHC filter for visual observation, and this is my first UHC filter. I was able to see the M94 galaxy, which I had never seen before against the bright sky background, with my 8-inch SCT. This filter makes the sky appear much darker while keeping most nebulae visible. I noticed significantly better contrast with the M17 Omega Nebula, though I feel that some fine details might have been filtered out and lost. I would not recommend it for visual observation of globular clusters like M3 and M5. The image was only slightly less sharp, and I thought I saw some reflections. The craftsmanship is excellent; the glass appears to be top quality and very clean. In my video, you can see that this filter gives an image with a slight violet tint. I can't compare it to a high-end UHC filter because I don't have one, but for its price, I think this filter is excellent. It will most definitely help you see faint deep-sky objects that you might have wondered if they were even there. Review: The virtue of high contrast filter (or city light filter) is to coat some relevant materials on very flat glass, selectively transmitting wavelength that suits the filter's purpose. So ideally speaking if you live in Bortle class 1 area, you don't need it. But there are only a few places you will find near your city even in the western side of the US. Therefore this filter can do the right job for you, for most cases. Indeed, non-flat glass and uneven coating will mar your filter and in the end, it mars the quality of an optical image projected on your eyepiece or the camera sensor. For that, perhaps very high-end quality astrophotography might want something more expensive filters. As an amateur, this filter is just perfect. You may lose some lights as filters wouldn't have 100% transmittance for necessary wavelengths. Despite such light loss, transmitting only the necessary wavelengths is important as your camera sensor doesn't want to be saturated by unnecessary wavelengths hitting your sensor. One of the best representative unnecessary wavelength shall be city light. Longer you expose through one shot of the picture, more importance of the filter you fill find. Attached is Trifid nebula,stacked many images taken 30 seconds for each. ## Features - 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 - 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 - Optical glass lens; aluminum frame; significantly reduces light pollution;great for city and suburban observation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07R38KR1P | | Best Sellers Rank | #816,014 in Electronics ( See Top 100 in Electronics ) #30 in Telescope Filters | | Generic Name | filters | | Item Dimensions LxWxH | 7.5 x 4.8 x 0.1 Centimeters | | Item Weight | 50 g | | Item model number | FF9131B | | Manufacturer | china | | Product Dimensions | 7.5 x 4.8 x 0.1 cm; 50 g | ## Product Details - **Brand:** SVBONY - **Coating Description:** No Coating - **Material:** Aluminium, Glass - **Photo Filter Effect Type:** Enhancing - **Photo Filter Thread Size:** 48 Millimetres ## Images ![SVBONY Telescope Filter 2" UHC Filter for Observations of Deep Sky Objects Ultra High Contrast Filter Reduce Light Pollution - Image 1](https://m.media-amazon.com/images/I/61td9d8qQ0L.jpg) ![SVBONY Telescope Filter 2" UHC Filter for Observations of Deep Sky Objects Ultra High Contrast Filter Reduce Light Pollution - Image 2](https://m.media-amazon.com/images/I/71sdIh4E1vL.jpg) ![SVBONY Telescope Filter 2" UHC Filter for Observations of Deep Sky Objects Ultra High Contrast Filter Reduce Light Pollution - Image 3](https://m.media-amazon.com/images/I/617AmU2ZNuL.jpg) ![SVBONY Telescope Filter 2" UHC Filter for Observations of Deep Sky Objects Ultra High Contrast Filter Reduce Light Pollution - Image 4](https://m.media-amazon.com/images/I/71qW9XQ0K0L.jpg) ![SVBONY Telescope Filter 2" UHC Filter for Observations of Deep Sky Objects Ultra High Contrast Filter Reduce Light Pollution - Image 5](https://m.media-amazon.com/images/I/71Ubsczph9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Review *by Ε½***O on 9 August 2024* I used the SVBONY 2-inch UHC filter for visual observation, and this is my first UHC filter.

Was this some kind of disgruntled employee at the factory? Was this a previously returned item? I'll never know. I tried my best to clean it, but several spots remain. Replacing immediately. Edit: amazon exchanged it for another and this one is perfect. ## Frequently Bought Together - SVBONY Telescope Filter 2 inches UHC Filter for Observations of Deep Sky Objects Ultra High Contrast Filter Reduce Light Pollution - SVBONY Telescope Filter 2 inches CLS Filter City Light Pollution Reduction Filter Broadband Filter Suitable for Deep Sky Visual Astronomical Photography - SVBONY Telescope Filter UV IR Cut Block Filter Infra Red Filter CCD Camera for Astrophotography Telescope UV Filter 2 inch Threads for DSLR Camera --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/483956438-svbony-telescope-filter-2-uhc-filter-for-observations-of-deep](https://www.desertcart.tn/products/483956438-svbony-telescope-filter-2-uhc-filter-for-observations-of-deep) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
