This custom-fit cover, made from a specialized black, light-proof material, blocks stray light and stabilizes air currents within the optical path of your 10″ instrument, directly improving views of faint deep-sky objects.\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\u003eMaximize Contrast for Your 10\" Truss Telescope\u003c\/h3\u003e\n\u003cp\u003eAn open truss design is excellent for portability and rapid cooling, but it leaves the optical path vulnerable. Stray light from streetlights, yard lights, or even the Moon can enter the tube and wash out faint nebulosity and galaxy details. This shroud creates a dark optical tunnel, restoring the high-contrast background needed to see the most delicate structures.\u003c\/p\u003e\n\u003cp\u003eThe material also helps manage thermal currents inside the tube. By preventing disruptive breezes from crossing the light path and containing the boundary layer of air, it stabilizes the image and minimizes local seeing effects, leading to sharper, more detailed views of planets and double stars.\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\u003eCustom-Fit Design for Unobstructed Operation\u003c\/h3\u003e\n\u003cp\u003eThis is not a simple, shapeless bag. The Truss Shroud is made from a flexible, latex-type material that can be manipulated to achieve a snug fit on almost any 10\" truss-tube configuration. It is designed to accommodate the realities of an imaging or observing setup.\u003c\/p\u003e\n\u003cp\u003eYou can easily shape the shroud around your focuser, finder scope, and dovetail plates without impeding access or function.

The shroud prevents stray light from washing out the faint outer loops of nebulosity, making them more visible against a blacker sky. It also helps stabilize the view, allowing for higher-magnification study of the Trapezium star cluster at the nebula's core.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill this shroud fit my 10\" Dobsonian if it has a truss design?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this shroud is designed for 10\" truss-tube telescopes, which includes many popular truss-tube Dobsonian models.

While it protects the optics from disruptive breezes, the shroud itself presents a larger surface area and can act like a sail in gusty conditions. On very windy nights, this can cause vibrations in the telescope structure, so it's best used in calm to moderately breezy conditions.\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\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003e10″ Truss-Tube Telescopes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eBlack, light-proof, flexible fabric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Function\u003c\/td\u003e\n\u003ctd\u003eStray light and airflow control\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\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/davidastro.com\/pages\/orion-optics-uk-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eOrion Optics UK 1-Year Warranty\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Orion Optics UK","offers":[{"title":"Default Title","offer_id":52942369095965,"sku":"OOUK-ODK10TR-MS","price":852.14,"currency_code":"USD","in_stock":true}],"url":"https:\/\/davidastro.com\/fr-us\/products\/orion-optics-uk-odk10tr-ms","provider":"David Astro","version":"1.0","type":"link"}
