The Best Light Pollution Filter Telescope Reviews: Connecting Skies to People<\/span><\/h2>\n
Light pollution is inevitable if you live in an urban area. City lights are no obstacle to seeing stars\u2026 if the star is Charlie Chaplin. In reality, light from numerous sources disperses in the atmosphere, reflecting from microscopic particles, and spoils star watching just like background noise spoils enjoying the music. A good filter, though, effectively cuts the range of the specter where the noise is found and lets you see the sky bright and clear.<\/p>\n
Do light pollution filters work?<\/div>\nHow do you tell a good light pollution filter from a bad one? A good city light filter fits your device and does its job, that\u2019s it. Filters are a too specialized segment to bear too many differences. Still, not all of them are created equal. Now, let\u2019s go through some filters considered the best.

\u201cAstronomer’s favorite brand\u201d; that\u2019s what Svbony claims to be, and it\u2019s mostly true. This brand was founded in China in 2009. What do you know about modern Chinese literature? Me, I only know Liu Cixin, and his The Three-Body Problem (a brilliant sci-fi novel exploring outer space) was published in 2008. Did it influence the founders of Svbony? Did they envision interest in astronomy growing? Or had it already been growing, inspiring both Svbony and Liu Cixin? Anyway, the brand indeed manufactures various astronomy-related products, from telescopes and astronomy cameras to accessories like this filter.<\/p>\n
The filter by SVBONY is a 1.25\u201d one suitable for 1.25\u201d eyepieces, the most commonly seen among amateur telescopes. It comes along with other filters by Svbony, the array including specialized moon filters for reducing glare, linear polarizers, and other filters. Some of these filters are even more expensive than an entry-level telescope by the same brand. However, it\u2019s not the case with this one: the price is slightly above $20.<\/p>\n
If you are new to this, you\u2019ll be fascinated just by the fact that it has a filter at all. A round-shaped metal frame has a changing color, looking violet or green, depending on the angle. The effect becomes even more stunning once you put it on the eyepiece.<\/p>\n
As for parameters, it\u2019s designed to reduce the 400-630 nm emission, except for the range between 465-515 nm, thus filtering the ranges where most of the pollution light lies. The effect of it is seen with the naked eye. The night sky looks darker, and the stars on it appear brighter. It\u2019s exceptionally well seen with nebulae. However, that\u2019s not the case with planets and satellites like the Moon; light pollution will not affect their visibility.<\/p>\n
Not only can you view the Universe with this telescope light pollution filter but also take photographs as well. This diameter is mostly used in telescopes designed to view objects in the sky, like stars, planets, nebulae, etc.
\nLast but not least: this one is made of durable metal and glass and is well protected. The case is filled with foam and does a great job protecting the filter, so you better not dispose of it immediately, especially if you travel a lot with your telescope.
\nPROS:<\/div>\n- \n

- Brand:\u200e Gosky<\/li>\n
- Photo Filter Thread Size: 30 Millimeters<\/li>\n
- Material: Plastic<\/li>\n
- Photo Filter Effect Type: Enhancing<\/li>\n
- Size: 1.25 inch<\/li>\n
- Targets: enhances contrast on reddish planetary detail.<\/li>\n<\/ul>\n
Gosky is also a well-known optics brand, offering a diverse array of devices, including binoculars, microscopes, and telescopes, and accessories for them. According to its website, it\u2019s a \u201ccompany registered in the US,\u201d which reads as \u201cChinese but has a certain quality control for overseas sales.\u201d No wonder a company that manufactures telescopes also has a lot of accessories in store (quite literally). It was established in 2004 in China (the same year in Albuquerque, Mike\u2019s granddaughter watched the sky, and her grandpa watched around for Lalo Salamanca) and has built itself quite a firm reputation.<\/p>\n
Unlike the one by Svbony, the filter by Gosky does not cover two distinct ranges but instead filters the range from 20 to 1000+ nm with varying intensity, focusing on filtering the emission at about 300 nm, 570-620 nm, and at about 800 nm. It is an entirely different decision that results in a distinct impression.<\/p>\n
In terms of design and usability, though, it shares a lot with our top pick. It is also made of metal (though it looks a little ruder) and comes in an easy-to-carry case. For amateurs, it\u2019s great that it has the \u201cLight Pollution Filter\u201d inscription on the ring, which is more comprehensible for perfect strangers to astronomy than the brief \u201cUHC\u201d on the one by Svbony.<\/p>\n
One of the best things about this filter is that it has both male and female threads on its sides. Thus it can be stacked with other filters, which can be a great thing if you know which filters to use. You may even buy those from other brands; as they are designed to fit standard 1.25\u201d eyepieces, they should be compatible with Gosky ones as well unless defective.<\/p>\n
The quality\u2026 Hmm, if the item you got is decent, you will see the difference. Alas, there is a chance you get a defective one. Luckily, you can file for a replacement. But you will have to prove the one you received does not perform well. But given that its price is well under $30, you can give it a try. Especially if you specifically need a stackable one to experiment with multiple filters at once.

- Filters the pollution well;<\/li>\n
