TS PHOTOLINE (Individual) APO 102 mm f / 7 optical tube with a 3 "extractor and a 1:11 microfocuser, a high-end proposal for both visual observation and advanced astrophotography.
• 102 mm objective lens diameter • focal length of the lens: 714 mm • lighted: f / 7 • hand-figured optical elements of the lens, one ED element • lens edges blackened • oklar lift: 3 "with reductions to 2" and 1.25 " • length: 61.5 cm • weight of the tube with clamps: 5.2 kg • very well corrected lens - ED doublet • perfect color correction makes the equipment appreciated by both planetary observers and people taking pictures of the Deep Sky • all glass / air surfaces covered with MC layers • adjustable lens cell • compact design, retractable urinal • eyepiece extractor with a fine focusing knob with a gear ratio of 1:11 • 3 "extract with large passage - vignetting does not occur for dies up to 24 x 36 mm • 3 "lift has no tendency to bend even under heavy load • large ball bearing for greater stability • 360 ° rotating extractor • 2 "and 1.25" reducers with brass clamp rings included • metal clamps (precisely CNC machined) • front lens cap included • We offer a separate 3 "field collector dedicated to this optical tube Moon planets star clusters nebulae landscapes 2 years
