distinction of being the most often viewed celestial object through backyard telescopes. It is undoubtedly beautiful and mysterious, and is one of those constants in our lives that connects us to every other being on our planet. Regardless of who we are or where we live or travel, we all look at the same moon. It is difficult to look at the Moon through a telescope and see all of the details due to its brightness. Our eyes are not ready for the bright beam of light that emits from the eyepiece, and they “stop down”, just as they would when you step out into the sunlight on a bright summer’s day. When we’re in the sunlight, we often wear sunglasses. They help us relax our eyes, protect us from glare, and help us see things more clearly. When amateur astronomers observe the Moon, we use a moon filter. A SVBONY Moon Filter provides similar benefits to those of sunglasses our eye relaxes and opens up to let us see more detail.\u003cbr\u003eSVBONY 1.25\" Moon filter for telescope eyepiece\u003cbr\u003ePremium Quality Metal Rim and Glass Lens\u003cbr\u003eFit standard sized 1.25\" eyepieces and accessories\u003cbr\u003eMounted in a nicely anodized housing\u003cbr\u003eThe filter has a mild effect of darkening the background of the night sky so that the fainter objects are more clearly seen contrasted against the blackness of space\u003cbr\u003eEffectively filters out selective wavelengths of low-pressure sodium and other man-made sources\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"detailmodule_text\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eFeatures:\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003e1.Lens material: pure optical glass lens\u003cbr\u003e2.Sleeve material: metal\u003cbr\u003e3.Caliber: 1.25\"\/31.7mm\u003cbr\u003e4.Filter thread: M28.5x0.6.\u003cbr\u003e5.Comes with a plastic box to keep it safe and clean when not in use\u003cimg style=\"margin-bottom:10px\" class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/H022c98b6471346ae861192be15a38aa4t.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eMulti-coated Glass with an lon-assisted Deposition Technology\/Standard 1.25 inch\/M28.5*0.6\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/Hdadd34320b844859a7fcc0cafa9c55d3v.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eA gentle effect that darkens the background of the night sky\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/H3e129629ee384b7f95b89063e4779502M.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eHow to use it?\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/H6ab4144e065446edac5722db9d55044fc.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eHow to Use a Moon Filter on a Telescope\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003eYou may be a little anxious about whether your telescope will take a filter for the moon if you’ve never used one before.\u003cbr\u003e\u003cbr\u003eWell, you should not fear!\u003cbr\u003e\u003cbr\u003ePretty much all telescope eyepieces come threaded at the bottom.

A 25% filter is fine up to around a 4” or 5” aperture. Anything bigger than that and you should be choosing a 13% filter.\u003cbr\u003e\u003cbr\u003e2) Variable Moon Filter\u003cbr\u003eAs its name suggests, this kind of filter lets you choose how much light to let through.\u003cbr\u003e\u003cbr\u003eIt consists two pieces of polarised glass which change how much light comes through, when turned relative to each other.\u003cbr\u003e\u003cbr\u003eThese are particularly useful if you're a keen moon observer.

You need a dedicated sun filter that fits over the telescope lens, not the eyepiece. Sun filters reject something like 99.9999% of the sunlight before it enters the telescope.\u003cbr\u003e\u003cbr\u003eQuestion:Why does this moon filter look green?\u003cbr\u003eAnswer:The filter reduces glare so that you can comfortably view the moon in more detail.
