It enhances Oxygen-III and Hydrogen-Beta emissions, revealing faint celestial details invisible to the naked eye or standard optics. Compatible with most telescopes, moisture resistant, and precision tested, it’s a budget-friendly essential for serious amateur astronomers seeking superb views of iconic nebulae such as Orion and Swan. ## Description desertcart.com : Astromania Telescope UHC Filter 1.25 Inch, Telescope Filter Improve Image Contrast Reduce Light Pollution, Telescope Accessories Nebula Filter for Superb Views of Orion Swan and Other Extended Nebulae : Electronics Review: Budget Friendly Filter that Works Well - I ordered this to cut down on light pollution and enhance the nebula I can view in the fall and winter months. I use it on my Seestar S30 with an adapter for 2in filters. This worked extremely well. Attached is a picture of the Jellyfish Nebula taken over several nights with the filter. Before using the filter the nebula was hardly visible because of light pollution. I think the filter did an excellent job of bringing out the Oxygen-III and Hydrogen-Beta emissions while blocking light pollution. The filter is affordable. It screws easily into the 2 inch adapter. I recommend this filter. Review: Great value! - I bought this to use with my 10-in Dobsonian telescope. While looking for the E. Veil Nebula I was literally unable to see it until I added this filter to the eyepiece. Once I did that I was able to see the structure in fairly good detail. I look forward to using it for other nebulae. Well worth the low price. ## Features - Nebula filter for increasing contrast; also suitable for use with smaller telescopes - Many objects only first become visible at all when using an UHC filter; but also; highlights such as the Orion; Lagoon or Swan nebulae; show a whole new side to them - Can be used at both light-polluted and dark sky sites; blocks the light from mercury and sodium-vapour lamps - 1.25 inch filter thread; each Astromania Ultra High Contrast Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the O-III and H-beta emission lines - As many celestial objects; such as nebulae; radiate at other wavelengths; a considerable increase in contrast can be achieved by this; the background sky appears darker and all at once; faint details become visible ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VCXJ9HN | | Best Sellers Rank | #14 in Telescope Filters | | Brand | Astromania | | Coating Description | Multi Coating | | Compatible Devices | Telescopes with 1.25 inch eyepiece | | Customer Reviews | 4.4 out of 5 stars 149 Reviews | | Enclosure Material | Aluminum, Optical Glass | | Item Dimensions L x W | 1.25"L x 1.25"W | | Item Weight | 0.3 Ounces | | Manufacturer | Astromania | | Manufacturer Part Number | SKU_AM_UF1E | | Material | Aluminum, Optical Glass | | Media Type | ProductImage | | Model Name | UF1B | | Model Number | SKU_AM_UF1B | | Photo Filter Effect Type | Neutral Density | | Photo Filter Thread Size | 31.75 Millimeters | | Screen Size | 1.25 Inches | | Special Effect | Neutral Density | | Thread Size | 31.75 Millimeters | | Water Resistance Level | Moisture Resistant | ## Product Details - **Brand:** Astromania - **Coating Description:** Multi Coating - **Material:** Plastic - **Photo Filter Effect Type:** Enhancing - **Photo Filter Thread Size:** 31.75 Millimeters - **Product Dimensions:** 1.25"L x 1.25"W - **Water Resistance Level:** Not Water Resistant ## Images ![Astromania Telescope UHC Filter 1.25 Inch, Telescope Filter Improve Image Contrast Reduce Light Pollution, Telescope Accessories Nebula Filter for Superb Views of Orion Swan and Other Extended Nebulae - Image 1](https://m.media-amazon.com/images/I/71edUO+HmeL.jpg) ![Astromania Telescope UHC Filter 1.25 Inch, Telescope Filter Improve Image Contrast Reduce Light Pollution, Telescope Accessories Nebula Filter for Superb Views of Orion Swan and Other Extended Nebulae - Image 2](https://m.media-amazon.com/images/I/715oKJS2uYL.jpg) ![Astromania Telescope UHC Filter 1.25 Inch, Telescope Filter Improve Image Contrast Reduce Light Pollution, Telescope Accessories Nebula Filter for Superb Views of Orion Swan and Other Extended Nebulae - Image 3](https://m.media-amazon.com/images/I/71EEertAz6L.jpg) ![Astromania Telescope UHC Filter 1.25 Inch, Telescope Filter Improve Image Contrast Reduce Light Pollution, Telescope Accessories Nebula Filter for Superb Views of Orion Swan and Other Extended Nebulae - Image 4](https://m.media-amazon.com/images/I/81aRqiuuxaL.jpg) ![Astromania Telescope UHC Filter 1.25 Inch, Telescope Filter Improve Image Contrast Reduce Light Pollution, Telescope Accessories Nebula Filter for Superb Views of Orion Swan and Other Extended Nebulae - Image 5](https://m.media-amazon.com/images/I/81mDMbdN2JL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Budget Friendly Filter that Works Well *by K***N on May 20, 2026* I ordered this to cut down on light pollution and enhance the nebula I can view in the fall and winter months. I use it on my Seestar S30 with an adapter for 2in filters. This worked extremely well. Attached is a picture of the Jellyfish Nebula taken over several nights with the filter.

Veil Nebula I was literally unable to see it until I added this filter to the eyepiece. Once I did that I was able to see the structure in fairly good detail. I look forward to using it for other nebulae. Well worth the low price. ### ⭐⭐⭐⭐⭐ Blown away by the added detail *by T***G on June 1, 2020* Viewing through a 6' dob, live in a Bortle10 area, and waited for the moon to "set" at 3:30am. Viewing in Sagittarius,viewing due South, 10 miles North of Charlotte. Went straight to Lagoon Nebula. Ive tried a general LPC (light pollution filter) in the past which helps. However with the LPC, I was only able to make out half of it. With the UHC, I was able to see both halves, and the dark lane through the middle. Had a similar experience with the Swan/Omega nebula. In the past could only make out the "body" of the Swan. Last night I was able to view the "head" as well as wisps of clouds, off the tail. I have never been able to make out the Trifid or Eagle Nebula until last night. Both were very faint and could make out very little detail. I have no comparison to other UHC filters. However if you are on a budget like myself and cant spend $100 on a filter, I feel like you will enjoy this filter. Very pleased with the purchase and details I was able to see. ## Frequently Bought Together - Astromania 1.25" UHC (Ultra High Contrast) Filter - Superb Views of The Orion, Lagoon, Swan and Other Extended Nebulae - Astromania 1.25" O-III Filter - Enhances Contrast During Visual Observation of Gaseous and Planetary Nebulae in All Sky Conditions, The Veil, Ring, Dumbbell and Orion Nebula, Among Many Other Objects - Astromania 1.25" H-Alpha Night Sky Filter --- ## 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.vn/products/171416633-astromania-telescope-uhc-filter-1-25-inch-telescope-filter-improve](https://www.desertcart.vn/products/171416633-astromania-telescope-uhc-filter-1-25-inch-telescope-filter-improve) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-07-05*
