CMOS cameras can thus deliver images like monochrome cameras. This new generation of filters enables amazing astrophotos directly from the heavily light-polluted city with all its artificial light sources.

The L-eXtreme filter is the better choice for fast optical systems at a competitive price. The filter isolates the H-Alpha and O-III emission lines from nebulae so that the contrast and signal-to-noise ratio between the nebula and the background are maximized.

This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.\u003c\/p\u003e\n\u003c!--end tab--\u003e\u003c!--start tab--\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eItem Number\u003c\/span\u003e \u003cspan class=\"speccell\"\u003eEPWP12009–01\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eFocal Length\u003c\/span\u003e \u003cspan class=\"speccell\"\u003e9mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eLength\u003c\/span\u003e \u003cspan class=\"speccell\"\u003e145mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWidth\u003c\/span\u003e \u003cspan class=\"speccell\"\u003e60mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eWeight\u003c\/span\u003e \u003cspan class=\"speccell\"\u003e21.2oz; 602g\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eBarrel Size\u003c\/span\u003e \u003cspan class=\"speccell\"\u003e2.00\"\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eEye Relief\u003c\/span\u003e \u003cspan class=\"speccell\"\u003e12.5mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spanrow\"\u003e\n\u003cspan class=\"speccell speccell-left\"\u003eField Stop Diameter\u003c\/span\u003e \u003cspan class=\"speccell\"\u003e15.7mm\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c!--end tab--\u003e\u003c!--start tab--\u003e\n\u003ch1 id=\"video\"\u003e\u003c\/h1\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/ntg78ZHu93U\"\u003e\u003c\/iframe\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003c!--end tab--\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":67609048809787,"sku":"EPWP12009-01","price":899.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/9185\/9515\/files\/120_9mm.png?v=1790775541"},{"product_id":"nebula-filter-h-alpha-2-inch-7nm","title":"Nebula Filter H-Alpha 2-inch 7nm","description":"\u003c!--start tab--\u003e\n\u003cp\u003eIn addition to the turbulence in the air, the brightening of the night sky is the greatest obstacle to observing faint objects beyond the solar system.

First of all, it allows you to increase the magnification of any eyepiece with the same barrel size that you already own. In other words, 3 eyepieces offer 6 magnification choices with the addition of a focal extender. Secondly, most of the time, lower magnification eyepieces have better eye relief than higher power models. When using a focal extender to increase your magnification, you get to enjoy the generous eye relief of the lower power eyepiece, and that’s quite a bonus, especially for eyeglass wearers or for those with fast telescopes who can really push high magnification eyepieces. Remember, we make focal extenders in 2X, 3X and 5x models, so there is something for every style of telescope.\u003c\/p\u003e\n\u003cp data-end=\"435\" data-start=\"154\"\u003eExplore Scientific focal extenders feature a telecentric optical design, using multiple precision lens elements to deliver light rays that remain parallel to the optical axis.

This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.\u003c\/p\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":67894060155195,"sku":"EPWP8211-01","price":149.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/9185\/9515\/files\/11_2c13f49d-bda1-4c6a-be42-115e1b649881.jpg?v=1793736218"},{"product_id":"100-series-14mm-waterproof-eyepiece","title":"100° Series 14mm Waterproof Eyepiece","description":"\u003c!--start tab--\u003e\n\u003cp\u003eExplore Ultra-Wide Eyepieces - Comfort, Quality, Value.

The visual effect of these eyepieces with their long eye-relief and their 68° apparent field is truly a full-immersion experience. The 68° Series eyepieces are parfocal (meaning they focus at near the same point regardless of the focal length you select) and come with a removable and foldable soft silicone rubber eyecup for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.\u003c\/p\u003e\n\u003cp\u003eProtection from the Outdoors - By making the eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled.\u003c\/p\u003e\n\u003cp\u003eArgon atoms are larger than that of Nitrogen and therefore they are less likely to leak or diffuse their way through the seals over the life of the eyepiece. The atomic radius of Argon is larger than Nitrogen by 0.13 angstroms and has a larger atomic volume by 11.2 cubic centimeters\/molecule. Argon also has superior inertness vs Nitrogen (i.e. forming few or no chemical compounds with other elements) that prevents adverse reactions with eyepiece components and therefore extends the longevity of the internal components, and also prevents chemical reactions with other elemental contaminants that may be introduced through a weakened seal. And, finally because Argon is less conductive of heat than Nitrogen, Argon cools slower thereby buffering the effects of rapid temperature changes of the optics.\u003c\/p\u003e\n\u003cp\u003eThe sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements.
