It threads directly into any standard 1.25\" eyepiece with its M28.5x0.6 threads, dimming the overwhelming glare of the Moon to reveal subtle surface detail. This filter improves contrast not just on the Moon, but on bright planets as well.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eReduce Glare with a 1.85mm Contrast-Boosting Filter\u003c\/h3\u003e\n\u003cp\u003eViewing the Moon, especially during its brighter phases, can be uncomfortably dazzling and wash out fine details. This filter reduces the overall brightness, acting like sunglasses for your telescope, which allows your eye to relax and perceive more subtle features like crater rays, rilles, and variations in mare composition. The 1.85mm thick optical glass is designed as a multi-bandpass filter that also helps darken the sky background, increasing the contrast between your target and the surrounding space.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUniversal Fit: M28.5x0.6 Threads for 1.25\" Eyepieces\u003c\/h3\u003e\n\u003cp\u003eEngineered for maximum compatibility, the SVBONY Moon Filter features standard M28.5x0.6 threads. This ensures it can be screwed directly onto the barrel of any 1.25\" eyepiece, diagonal, or camera nosepiece. The durable, anodized metal housing protects the glass element, and its low-profile design allows it to be stacked with other filters, such as a color filter for planetary observation, to further isolate specific details.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the primary purpose of the SVBONY 1.25\" Moon Filter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe primary purpose of the SVBONY 1.25\" Moon Filter is to reduce the intense glare from the Moon, making observation more comfortable and revealing finer surface details that are otherwise washed out by the brightness.

While designed for the Moon, the SVBONY 1.25\" filter's glare-reducing properties are also effective for observing bright planets. It can help cut through the brightness of Jupiter and Venus, making it easier to see subtle cloud bands or phase details.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I attach the SVBONY 1.25\" Moon Filter to my telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe filter is not attached to the telescope itself, but to your 1.25\" eyepiece or accessory.

While it is not a dedicated deep-sky light pollution filter (like a UHC or CLS), it can provide a modest improvement in contrast on brighter objects observed from suburban skies.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs this SVBONY filter compatible with a 2\" eyepiece?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo, this specific model is the 1.25\" version with M28.5x0.6 threads and will not fit a 2\" eyepiece. SVBONY also manufactures a 2\" version (with M48x0.75 threads) for observers using larger format eyepieces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the SVBONY 1.25\" Moon Filter for imaging the Moon with my 8\" SCT?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, it's very useful for lunar imaging. The Moon is bright enough to saturate camera sensors with very short exposures. Using the SVBONY 1.25\" Moon Filter allows you to use longer, more manageable exposure times, which can reduce noise and prevent blowing out highlights in bright areas like the crater Tycho.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSVBONY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilter Size\u003c\/td\u003e\n\u003ctd\u003e1.25\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAvailable Models\u003c\/td\u003e\n\u003ctd\u003eF9114A (1.25\"), F9114L (2\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Type\u003c\/td\u003e\n\u003ctd\u003eM28.5x0.6 (1.25\"), M48x0.75 (2\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSubstrate Thickness\u003c\/td\u003e\n\u003ctd\u003e1.85mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eSVBONY 1.25\" Moon Filter\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003ePlastic Protective Case\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/svbony-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eSVBONY 1-Year Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SVBONY","offers":[{"title":"1.25\" Round Mounted","offer_id":52861233299741,"sku":"SV-F9114L","price":16.0,"currency_code":"CAD","in_stock":true},{"title":"2\" Round Mounted","offer_id":52861233332509,"sku":"SV-F9114A","price":20.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/SVBONY-1-25-Moon-Filter-Reduce-Glare-Optical-Glass-for-Telescope-1_d0fe9cfa-567e-4225-93aa-85aa17ec3b02.jpg?v=1788659999","url":"https:\/\/davidastro.com\/fr\/products\/svbony-moon-filter","provider":"David Astro","version":"1.0","type":"link"}
