## Overview

The Astromania UHC Filter is a 1.25-inch telescope accessory designed to dramatically improve nebula contrast by blocking common light pollution sources like mercury and sodium vapor lamps. 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.

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

### ⭐⭐⭐⭐⭐ 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.
