With high transmission rates for critical wavelengths, this filter allows you to see the universe in stunning detail, all while being a cost-effective choice for both amateur and professional astronomers. ## Description The UHC (Ultra-High Contrast) broadband filter is designed to improve the visibility of various deep-sky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lighting such as mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (skyglow). The filter is highly transparent in the main nebula emission lines at OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm) as well as SII (672nm). The filter is suitable for enhancing the contrast and details for both visual and photographic purpose in suburban and rural areas with heavy light pollution. Suitable for color CCD cameras and unmodified DSLRs that accept 1.25" filters. With narrower bandpass transmission gaps, this filter provides higher contrast than CLS filters. The UHC filter has a substantial red bandpass and offers superb views of objects like the Orion Nebula (M42) Light pollution filters do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula. ## Features - Cost Effective Light Pollution Rejects Mercury and Sodium Light While Increasing Contract High Transmission of OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm) as well as SII (672nm) ## Images ![Optolong 2" UHC Light Pollution Filter - Image 1](https://m.media-amazon.com/images/I/51+-gOJ+-BL.jpg) ![Optolong 2" UHC Light Pollution Filter - Image 2](https://m.media-amazon.com/images/I/41lRuy0MTXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good ultra high contrast filter *by B***O on Reviewed in the United States on June 27, 2020* I took this UHC filter to my astronomy club’s dark site a couple of weeks ago at the new moon - it performed magnificently! Really brought out the contrast in nebula particularly as well as galaxies.I was very impressed! ### ⭐⭐⭐⭐⭐ Amazing! *by T***8 on Reviewed in the United States on June 9, 2021* I'm an amateur astrophotographer. I have a unmodified DSLR camera and I have used this filter for a while in my image train. It blocks light pollution and helps harness the wavelengths emitted from nebulae. Would definitely recommend to take your Astrophotography to the next level. ### ⭐⭐⭐⭐⭐ Works well *by L***Y on Reviewed in the United States on August 21, 2020* Nice filter. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/161702183-optolong-2-uhc-light-pollution-filter](https://www.desertcart.pe/products/161702183-optolong-2-uhc-light-pollution-filter) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-04-23*
