The well-corrected optics offer an almost color-pure image due to the moderate aperture ratio and the built-in ED glass making it a superb choice for astrophotography or for impressive visual observations.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cem\u003eThe advantages of the TS ED80 Refractor:\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003col\u003e\n\u003cli\u003eVery well corrected ED optics - Fully Multicoated\u003c\/li\u003e\n\u003cli\u003eStable and accurate 2.5\" focuser - ball-bearing pull-out tube, adjustment by tooth drive.\u003c\/li\u003e\n\u003cli\u003e2\" receptacle with reduction to 1.25\" with ring clamping and additional photo thread M54 x 0.75.\u003c\/li\u003e\n\u003cli\u003eRobustly built tube with fixed dew cap and CNC pipe clamps to guarantee superior mechanical stability\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cem\u003eIdeal for Astrophotography:\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe precise focuser and fast optics make the 80 mm ED refractor a good telescope for astrophotography.
