That's right, you do not need to add an expensive flattener to the Askar 65PHQ, it is already ready to go for full frame imaging! The optical design is air-spaced and produces a 44mm image circle so you can use larger full frame sensors without vignetting. Of course, the Askar 65PHQ is also great for smaller APS sensors as well, and it even performs well visually with the addition of a diagonal. Not all astrographs on the market can come to focus when used visually, so this is a real bonus! Use your 65PHQ as a spotting scope, a long lens for terrestrial photography, solar work (with the proper filters in place), nighttime visual work, or astrophotography!\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eAbout the Focuser, OTA \u0026amp; Accessories\u003c\/h3\u003e\n\u003cp\u003eThe Askar 65PHQ comes with a nice big 2.5\" dual speed rack \u0026amp; pinion focuser with 1:10 fine focus adjustment. The focuser is capable of rotating 360-degrees so you can frame your image as you like, and there is a scale on the drawtube so you can achieve repeatable focus. This refractor telescope has a focal length of 416 mm and a focal ratio of f\/6.4. The OTA is CNC-machined, painted white, and has green trim...it is a very nice looking optical instrument!\u003c\/p\u003e\n\u003cp\u003eAlso included in the 65PHQ package is a pair of tube rings, a handle for easy transport and mounting, a 300 mm Vixen-style dovetail, a set of three photographic adapters, a finder base (finder and bracket sold separately) and an instruction manual.\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003e65PHQ Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAperture: 65 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eFocal Length: 416 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eFocal Ratio: f\/6.4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eObjective Lens: Quintuplet air-spaced APO\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eImage Circle: 44 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eLength with Dew Shield Retracted \u0026amp; Eyepiece Holder: 328 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eLength with Dew Shield Extended \u0026amp; Eyepiece Holder: 388 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eLength with Dew Shield Retracted \u0026amp; 3-Piece Adapter: 360 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eLength with Dew Shield Extended \u0026amp; 3-Piee Adapter: 420 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eOTA Weight: 2kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eOTA \u0026amp; Included Accessories Weight: 2.8kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eRear End Thread Type: M68x1 - M54x0.75, M54x0.75 - M54x0.75, and M54x0.75 - M48x0.75 (with 2\" filter thread inside)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eRear End of 3-Piece Photographic Adapters: M48x0.75\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: center;\"\u003eMaximum Additional Accessory Length for Imaging\u003cbr\u003ewith Focuser Fully Retracted\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFrom base of M48x0.75 Male Thread: 76 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eFrom base of M54x0.75 Male Thread: 105 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eFrom base of M68x1 Male Thread: 130 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: center;\"\u003eMaximum Additional Accessory Length for Observing\u003cbr\u003ewith Focuser Fully Retracted\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFrom base of 2\" Eyepiece Holder: 121 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Askar","offers":[{"title":"Default Title","offer_id":40117659172977,"sku":"ASK-65PHQ","price":807.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/Askar_65PHQ_Green_Main.png?v=1776459194","url":"https:\/\/khanscope.com\/en-fr\/products\/askar-65phq-f6-4-quintuplet-air-spaced-astrograph-with-green-trim-65phq-grn","provider":"Khan Scope Centre","version":"1.0","type":"link"}
