I live in suburban Sacramento and have significant light pollution. The filter works well on emission nebula (such as Orion). It does increase contrast between sky and the object observed. I could see more detail in the Orion Nebula. Given that it has narrow passes on the spectrum, there is a green tinge to what you are viewing, however I found this not to be an issue, since it works best on objec0st we do not perceive as colored. I use it with my Celestron 102mm f/10 refractor. Eyepieces were a Celstron 32mm Plossl and University Optics 26mm.

4.0 out of 5 stars Great for the Suburbs
Reviewed in the United States on November 13, 2014
Size: 1.25"Verified Purchase
Living in a suburb often means that even on clear nights, deep-sky objects can be challenging. Normally I work with an Orion 130EQ and an XT10, so aperture is not a significant problem. The Ring Nebula is easily visible, but the Andromeda galaxy can be challenging to resolve (growing up in very rural Missouri, I was accustomed to imaging our nearest large galactic neighbor naked eye). Adding the SkyGlow filter improved the visibility of the Ring Nebula significantly, Andromeda somewhat, and made many of Orion's deep objects more accessible. The only downside is the greenish-tint often imparted on starlight.

However, on the whole, if you live in moderately light-polluted environments, I would recommend going with this filter over any number of the O(III) 1.25 inch filters readily available. O(III) is great if you have pure skies and wish to observe nebulae or galaxies, but the SkyGlow is fantastic if you just want to observe in a less-than-perfect environment.

Reviewed in the United States on October 20, 2015
Size: 1.25"Verified Purchase
Let me start by saying this is the only filter of this type I've used, and that I'm not heavily experienced in the hobby. That said....... I live in an area that is at very least moderately light polluted. I have used this a few times now. I have found that it helps resolve Nebulas, and Galaxies, a little. I wasn't sure what to expect, and was of course hoping to have all my light pollution problems solved. Hey, I can dream can't I? It does help Nebulas and Galaxies to appear more defined. It just didn't knock my socks off. I think it's worth the money I spent. If you're new to the hobby, my advise would be to join an astronomy club and see if other members have different types and makes of filters for you to look through.

Maybe I expected too much, living in light-polluted upper Manhattan, but this filter didn't seem to do much, as opposed to the "swan band" filter I purchased which makes certain nebulae like M-42 pop right out of the eyepiece at you!

5.0 out of 5 stars Orion Skyglow Broadband Fliter
Reviewed in the United States on January 15, 2013
Size: 1.25"Verified Purchase
I have the Ultra and the Oxygen-III for Nebula viewing. I purchased this for two reasons:
1.) Some internet articles suggested this filter will help in seeing some Nebula's, and other faint objects independent of light pollution issues from the viewing area.
2.) I'm in a terrible Light Polluted area, and any help is welcome!!

I was able to see M1 (crab Nebula) from my yard using this filter. But the view was very very faint (.5 to1 on a scale of 10). According to articles for Urban viewing, they recommend skipping M1, too faint - need dark skies.

So I'm happy...

I had this filter but returned it to get the sky glow imaging filter but the back ground on this filter is blue. I sure that post processing will fix that but I am not there yet. so that being said the $49 sky glow is better for images to me at this time and I will reorder it. it is good for viewing and imaging , it is worth the money!

He utilizado la lente para astrofotografía en la ciudad, con contaminación luminosa. Funciona muy bien si la contaminación luminosa no es excesiva. Sin embargo, me parece importante señalar que he visto que no filtra bien cuando la iluminación externa proviene de luces LED, lo cual debe ser por la longitud de onda para la cual está diseñada esta lente, por lo cual no lo considero un defecto de este producto.

5.0 out of 5 stars Mejora el contraste en las observaciones utilizándolo correctamente.
Reviewed in Spain on December 30, 2018
Size: 1.25"Verified Purchase
De los tipos de filtros anti contaminación lumínica, yo me decanté por este filtro que no es tan restrictivo con las longitudes de ondas luminosas. Yo tengo un telescopio pequeño (113/450mm) y un filtro más restrictivo (filtro de banda estrecha) solo sería válido, (en mi caso), para exposiciones largas (astrofotografía).

Es muy importante hacer una adaptación de tus ojos a la oscuridad, para poder valorar correctamente el desempeño de este filtro, por ello hay que estar entre 20 a 30 minutos sin exposición directa a ninguna fuente luminosa que pueda reducir el tamaño de la pupila.
En mi caso, si he notado un aumento del contraste. La visualización de las estrellas en un entorno contaminado luminicamente es mejorado (aunque está limitado obviamente por la intensidad de la contaminacion lumínica en el lugar de observación)
En la documentación de mi filtro venía incluido un informe de exploración de longitud de onda realizada con espectrofotómetro, donde aparece la gráfica y valores resultantes específicos de mi filtro. Ese test fué realizado 20 días antes de mi compra.
Algo realmente inesperado para mí y que aunque no tiene una aplicación práctica en mi caso, si que es de agradecer el control de calidad de este producto.
Como aficionado a la astronomía, estoy muy contento con el material que he adquirido de la marca Orion.

Ottimo filtro, banda passante abbastanza ampia da poter essere usato anche in visuale. Con reflex permette di aumentare notevolmente il segnale catturato dalla nebulosa, e l'elaborazione dell'immagine diventa molto più semplice. Chiaramente se avete la fortuna di osservare/riprendere da siti buii non vi serve a niente :).
