## Description

desertcart.com : Astromania 1.25" UHC (Ultra High Contrast) Filter - Superb Views of The Orion, Lagoon, Swan and Other Extended Nebulae : Electronics

Review: Great Filter for Viewing from City - This is, so far, my favorite purchase for my new telescope. I can see the Orion nebula now (which I could not see in my light polluted sky) previously. It is very faint, but I can see it now! One of my unexpected favorites to look at with this new filter is Betelgeuse because I can see it and its color so much better now. The filter came with a very nice, sturdy, case as well.
Review: it makes a difference even on a fairly small refractor - Unlike a moon and sky filter this combines some more realistic filtering of non-nebular light while passing a good deal of light. I clearly noticed improvement in nebula contrast with very little, but some, loss of galaxy brilliance as you would expect. It's decent filter with net benefits at even 80-90mm aperature.

## 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.
