It has an aperture of 100mm and the focal ratio is f\/5.5. Z4 is a sextuplet astrograph with three pieces of lens at the front and three pieces at the back, and two of them are ED glasses. Just like other series of Sharpstar astrographs, Z4 is designed as self-flattened so there is no need to calculate the back focus. You can just make the target stay at the focus, and the optical system is perfect for imaging.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe appearance of Z4 breaks through the previous style of Sharpstar with its matte gray coating. Light gray lens tube plus dark gray focuser and tube ring, make the astrograph looks calm but vibrant. The tube ring has a handle on the top which is easy to carry and assemble. The handle is designed as a slot on which you can mount a finder base, etc. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eZ4 uses a large 3.4” focuser with a 1:10 fine adjustment knob and a 360° rotator for easy focusing and angle adjustment. It has M86, M68, M54, M48 adapters, and the M48 one has an internal thread that can fit 2” filters. And a 300mm Vixen-style dovetail plate, makes it easier to balance on the equatorial mount.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eFocal ratio：F\/5.5\u003cbr\u003eObjective lens：sextuplet fully air-spaced APO (including two ED glasses)\u003cbr\u003eImage circle：36mm\u003cbr\u003eBack focus:55mm（from the M48 thread）\u003cbr\u003eTotal length：482mm\u003cbr\u003eNet weight：4.3kg\u003cbr\u003eGross weight：5.6kg（without the aluminum box）\u003cbr\u003eRear-end thread ：M48×0.75 male thread\u003cbr\u003eTapered adapter:M86×1-M68×1\u003cbr\u003eM68×1-M54×0.75\u003cbr\u003eM54×0.75-M54×0.75\u003cbr\u003eM54×0.75-M48×0.75（with M48×0.75 filter thread）\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eIn the Box\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eSharpStar Z4 APO Astrograph\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eTube Ring\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e300 mm Vixen-Style Dovetail Plate\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eCarry Handle\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e4-Piece Photographical Adapter\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eInstruction Manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/div\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cdiv data-mce-fragment=\"1\"\u003eSharpStar Warranty\u003c\/div\u003e\n\u003c\/div\u003e","brand":"SharpStar","offers":[{"title":"Default Title","offer_id":43628297453797,"sku":"SS-Z4","price":3232.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/sharpstar-z4-apo-astrograph-z4-astronomy-plus.webp?v=1690488369","url":"https:\/\/istronomyplus.com\/products\/sharpstar-z4-apo-astrograph-z4","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
