The motorized grating allows you to remotely select the central wavelength of your spectrum, making it possible to study different spectral features of a target in a single session.

The Uvex Motors module allows you to control the spectrograph's grating (central wavelength) and focus from a computer, eliminating the need to be physically at the telescope.

This feature allows you to automate your entire data acquisition sequence, from capturing the target's spectrum (Sky) to taking Flat, Dark, and reference lamp (Calibration) frames.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I control the Uvex Motors module with software other than DEMETRA?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. While it is designed for seamless integration with Shelyak's DEMETRA software, the module uses an open communication protocol called \u003cstrong\u003eUSIS\u003c\/strong\u003e. Shelyak provides documentation for this protocol, allowing advanced users to write their own scripts or integrate control into third-party observatory software like N.I.N.A. or SGP via custom drivers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the Uvex Motors module help when observing a Be star like Gamma Cassiopeiae?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eBe stars like Gamma Cassiopeiae (gamma Cas) have dynamic emission lines (like H-alpha) that change over time. The Uvex Motors module allows you to precisely and repeatedly center your grating on these specific lines night after night. You can also remotely check focus to ensure you achieve the highest possible resolution to measure subtle changes in the line profiles, which is crucial for this type of scientific work.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill I need to rebalance my telescope after installing the 1.46 kg Uvex Motors module?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eMost likely, yes. The module and the UVEX spectrograph together weigh 1.46 kg (without a camera). This additional weight will almost certainly require you to rebalance your mount in both axes to ensure accurate tracking and guiding.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eI use an 8\" SCT at f\/10.

The motorized focus control of the Uvex Motors module is a major advantage. It allows you to make tiny, precise adjustments to the spectrograph's internal focus remotely throughout the night, ensuring your spectral lines remain sharp and narrow without having to touch the telescope's primary focuser, which can introduce mirror shift.\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\u003eMotorized Grating Control\u003c\/td\u003e\n\u003ctd\u003eAllows remote selection of the central observation wavelength.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotorized Focus Control\u003c\/td\u003e\n\u003ctd\u003eAllows remote fine-tuning of focus for optimal optical quality.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibration Module Control\u003c\/td\u003e\n\u003ctd\u003eRemotely controls an external calibration unit, switching between Sky, Dark, Flat, and Calibration light sources.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (with UVEX)\u003c\/td\u003e\n\u003ctd\u003e153 x 154 mm, Height: 133 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (with UVEX, no camera)\u003c\/td\u003e\n\u003ctd\u003e1.46 kg\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\"\u003eUvex Motors Module\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\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/Shelyak_UVEX_Motors_Module_Manual.pdf\" target=\"_blank\"\u003e\u003csvg class=\"DAV-img-box\" viewbox=\"0 0 512 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"\u003e\u003cpath d=\"M0 64C0 28.7 28.7 0 64 0L224 0l0 128c0 17.7 14.3 32 32 32l128 0 0 144-208 0c-35.3 0-64 28.7-64 64l0 144-48 0c-35.3 0-64-28.7-64-64L0 64zm384 64l-128 0L256 0 384 128zM176 352l32 0c30.9 0 56 25.1 56 56s-25.1 56-56 56l-16 0 0 32c0 8.8-7.2 16-16 16s-16-7.2-16-16l0-48 0-80c0-8.8 7.2-16 16-16zm32 80c13.3 0 24-10.7 24-24s-10.7-24-24-24l-16 0 0 48 16 0zm96-80l32 0c26.5 0 48 21.5 48 48l0 64c0 26.5-21.5 48-48 48l-32 0c-8.8 0-16-7.2-16-16l0-128c0-8.8 7.2-16 16-16zm32 128c8.8 0 16-7.2 16-16l0-64c0-8.8-7.2-16-16-16l-16 0 0 96 16 0zm80-112c0-8.8 7.2-16 16-16l48 0c8.8 0 16 7.2 16 16s-7.2 16-16 16l-32 0 0 32 32 0c8.8 0 16 7.2 16 16s-7.2 16-16 16l-32 0 0 48c0 8.8-7.2 16-16 16s-16-7.2-16-16l0-64 0-64z\" fill=\"#0047a7\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eShelyak UVEX Motors Module Manual\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/shelyak-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eShelyak 1-Year Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shelyak","offers":[{"title":"Default Title","offer_id":52943040053533,"sku":"SHK-PF0074","price":2453.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/Shelyak-Uvex-Motors-module-1_d2d12418-d094-4058-ae73-21a70450c813.jpg?v=1789616127","url":"https:\/\/davidastro.com\/fr\/products\/shelyak-pf0074","provider":"David Astro","version":"1.0","type":"link"}
