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: Dust Clouds More Visible - This definitely enhances dust clouds. I used it with a 2" 18mm orthoscopic eyepiece last night with my 17.5" Dobsonian on the Orion Nebula. The clouds are definitely brighter and more obvious with it than without it. Other reviews have complained about overall light loss. Yes, there is some reduction in overall brightness but with a 17.5" scope, it is not dramatic. I have not used it on other nebulae yet (recovering from appendectomy) but I have high hopes. ## 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 | #43 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 155 Reviews | | Enclosure Material | Aluminum, Optical Glass | | Item Dimensions L x W | 1.25"L x 1.25"W | | Item Weight | 8.53 g | | Manufacturer | Astromania | | Manufacturer Part Number | SKU_AM_UF1E | | Material | Aluminum, Optical Glass | | Media Type | ProductImage | | Model Name | UF1B | | Model Number | SKU_AM_UF1B | | Number of Items | 1 | | Photo Filter Effect Type | Enhancing | | Photo Filter Size | 31.75 millimeters | | Photo Filter Thread Size | 31.75 millimeters | | Screen Size | 1.25 inches | | Special Effect | Enhancing | | 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 Filter 1.25 Inch UHC Filter Improve Contrast Nebula - Image 1](https://m.media-amazon.com/images/I/71edUO+HmeL.jpg) ![Astromania Telescope Filter 1.25 Inch UHC Filter Improve Contrast Nebula - Image 2](https://m.media-amazon.com/images/I/715oKJS2uYL.jpg) ![Astromania Telescope Filter 1.25 Inch UHC Filter Improve Contrast Nebula - Image 3](https://m.media-amazon.com/images/I/71EEertAz6L.jpg) ![Astromania Telescope Filter 1.25 Inch UHC Filter Improve Contrast Nebula - Image 4](https://m.media-amazon.com/images/I/81aRqiuuxaL.jpg) ![Astromania Telescope Filter 1.25 Inch UHC Filter Improve Contrast Nebula - 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.
