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.
Review: Good at highlighting a nebula - Really brought the nebula into view

## 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

### ⭐⭐⭐⭐ Good at highlighting a nebula
*by P***A on March 11, 2026*

Really brought the nebula into view

### ⭐⭐⭐⭐⭐ 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.
