This means you can also use cameras with full-frame sensors giving you a nice wider field of view of the target you are imaging.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cem\u003eAdaptation of Cameras:\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe generous working distance is between 65mm and 155mm from the M68 thread and to connect a DSLR or an Astrocamera via the M48 thread, you will need the M68A-M48A-30 adapter. Cameras with a T2 (M42x0.75) connection will require a TSM48i-T2A reduction adapter. The adapter itself is only 6mm thick, so you still have enough space for a DSLR camera with T2 adapter or an Astrocamera.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eFeatures and benefits of the TSQ-80APO:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003cul\u003e\n\u003cli\u003eModern 80 mm f\/6 FPL53 triplet lens\u003c\/li\u003e\n\u003cli\u003eIntegrated 2-element field corrector with optimized distance to the lens\u003c\/li\u003e\n\u003cli\u003e2.5\" CNC gear focuser (Rack \u0026amp; Pinion) with ball bearing and 1:10 micro reduction\u003c\/li\u003e\n\u003cli\u003eEach Quadruplet Apo is checked by Teleskop-Service before shipping.\u003c\/li\u003e\n\u003cli\u003eThe moderate aperture ratio of f\/6.8 is well suited for DSLR cameras and Astrocameras.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cstrong\u003eTechnical Details:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003cul\u003e\n\u003cli\u003eAperture: 80 mm\u003c\/li\u003e\n\u003cli\u003eFocal length: 544 mm\u003c\/li\u003e\n\u003cli\u003eAperture ratio: f\/6.8\u003c\/li\u003e\n\u003cli\u003eLens: FPL53 triple lens with air gap\u003c\/li\u003e\n\u003cli\u003eCorrector: 2-element corrector at an optimized distance from the lens\u003c\/li\u003e\n\u003cli\u003eField of view: 45 mm diameter with full correction and illumination\u003c\/li\u003e\n\u003cli\u003eBack focus from 2\" receptacle: 130mm with retracted extension\u003c\/li\u003e\n\u003cli\u003eBack focus from the M68x1 female thread: 148.5mm with retracted pull-out pipe\u003c\/li\u003e\n\u003cli\u003eAdjustment range of the extract: 90mm\u003c\/li\u003e\n\u003cli\u003eTube length with inserted dew cap: 450mm\u003c\/li\u003e\n\u003cli\u003eTube diameter: 89mm\u003c\/li\u003e\n\u003cli\u003eDew cap diameter: 112 mm\u003c\/li\u003e\n\u003cli\u003eCamera-side connection: 2\", 1.25\" and M68x1 female thread\u003c\/li\u003e\n\u003cli\u003eTube weight with tube clamps: 3.5kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eWhats included:\u003c\/em\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e80 mm Quadruplet Apochromat Refractor\u003c\/li\u003e\n\u003cli\u003eCNC pipe clamps\u003c\/li\u003e\n\u003cli\u003eGP\/EQ5 Level dovetail bar with photo tripod connection\u003c\/li\u003e\n\u003cli\u003e2.5\" RPA focuser with 2\" receptacle\u003c\/li\u003e\n\u003cli\u003eReduction from 2\" to 1.25\"\u003c\/li\u003e\n\u003cli\u003eViewfinder shoe\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"TS Optics","offers":[{"title":"Default Title","offer_id":42353498816755,"sku":"TSAPO80Q","price":1342.67,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/TSOpticsFPL5380APORefractorTelescope_4.jpg?v=1642869146","url":"https:\/\/www.horizonastronomy.ie\/en-pl\/products\/ts-optics-fpl53-apo-refractor-80-triplet","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
