This patented corrector system replaces your secondary mirror, transforming your telescope's optical geometry to gather light more than 22 times faster than at its native focal ratio. For the SCT owner who wants to image large targets like the Andromeda Galaxy or the Veil Nebula complex without guiding for hours, the Hyperstar is the most direct path to acquiring deep, high-quality data.\u003c\/p\u003e\n\u003cp\u003eThe core advantage of this speed is the radical reduction in exposure time. An image that would require a 25-minute guided sub-exposure at f\/10 can be captured with equivalent signal in just 60 seconds at f\/2.1. This change makes unguided imaging not only possible, but practical. The demands on your equatorial mount's tracking accuracy are significantly reduced, and the risk of a passing cloud or satellite ruining a long sub-exposure is minimized. This workflow opens up serious deep-sky imaging to observers with lighter-duty mounts or those who prefer a simpler, more portable setup.\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\u003eThe Patented f\/2.1 Corrector Lens System\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the Hyperstar is a multi-element optical corrector. When placed at the front of the telescope, it intercepts the light cone from the primary mirror and corrects for the severe coma and field curvature that would otherwise make imaging at this focal ratio impossible. The result is a 425mm focal length system that produces a wide, flat, and sharp field of view, delivering pinpoint stars across a 27mm image circle, fully illuminating sensors like the popular ASI294MC Pro.\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\u003ePrecise Collimation for Sharp Stars\u003c\/h3\u003e\n\u003cp\u003eBecause the Hyperstar becomes the primary optical element after the main mirror, its alignment is critical. The housing features an integrated collimation system with adjustment screws that allow you to precisely tilt the lens group. This ensures the optical axis of the Hyperstar is perfectly centered on your primary mirror's axis, a requirement for achieving sharp, symmetrical stars across the entire imaging field.\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\u003eIndependent Camera Rotation for Easy Framing\u003c\/h3\u003e\n\u003cp\u003eOnce you have achieved perfect focus and collimation, the last thing you want to do is disturb it.

This means it uses a slower primary mirror (f\/2.2 versus the f\/2 mirror in other SCTs). This means the HyperStar has to be slightly slower to retain its excellent optical performance. The difference between f\/2.2 and f\/2 is negligible.\u003c\/p\u003e\n\u003cbr\u003e\u003cbr\u003eWatch a HyperStar demo under light polluted skies using an Alt-Az mount. \u003cdiv class=\"fluid-width-video-wrapper\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/z4gj985zRns?rel=0\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\" data-mce-fragment=\"1\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/article\u003e\u003c\/section\u003e\u003c\/div\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Starizona","offers":[{"title":"No Filter Slider","offer_id":44968007663901,"sku":"STZ-HS4-C9.25","price":1679.0,"currency_code":"CAD","in_stock":true},{"title":"Add Filter Slider","offer_id":44968007696669,"sku":"STZ-HS4-C9.25-FS","price":1859.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/products\/Starizona-Hyperstar-Celestron-9-25__40693.1653511350.1280.1280.jpg?v=1684347781"},{"product_id":"starizona-hyperstar-v4-for-celestron-11","title":"Starizona HyperStar V4 for Celestron 11\"","description":"\u003c!-- more --\u003e\n\u003cdiv id=\"shopify-section-static-product\" class=\"shopify-section product--section\"\u003e\n\u003csection class=\"product--container layout--two-col\" data-product-wrapper=\"\"\u003e\n\u003carticle class=\"prod-description\"\u003e\n\u003cdiv class=\"product-description rte\" data-product-description=\"\"\u003e\n\u003cb\u003eFeatures\u003c\/b\u003e\u003cbr\u003e\n\u003cp\u003eThe HyperStar C11 lens converts a standard Celestron 11\" SCT from f\/10 to f\/1.9, making the system 25 times faster. That means 25-times shorter exposures! Now you can capture deep-sky images without guiding and without an equatorial wedge (in alt-az configuration). The HyperStar lens shortens the focal length of the telescope, giving a much wider field of view, and giving a greater tolerance of tracking errors, allowing for unguided, alt-az imaging.\u003c\/p\u003e\n\u003cp\u003eThe HyperStar 11 is compatible with a variety of cameras, including CCD, CMOS and DSLRs.
