For maximum contrast, each lens is supplied with the best possible multi-coating offered by the manufacturer.Item: 393442039228 TS-Optics Doublet SD Apo (rifrattore) 72 mm f/6 - FPL53 Obiettivo, TSAPO72F6. The air-spaced objective is adjustable mounted, of course. This high-quality lens offers an image free of false colour even in the high magnification range. The 72 mm FPL53 doublet lensWithout doubt, the heart of the refractor is the multi-coated 72mm f/6 objective with the FPL53 APO element from Ohara (Japan) and lanthanum glass element as second special glass. The 1:11 dual speed transmission offers precise focusing also for astrophotography.Ī female M63x1 thread on the drawtube allows threaded connections. The drawtube is adjusted using a rack which is non-interacting with the bearing itself, thus allowing precise adjustment even at maximum load. Top mechanics through the 2,5" rack and pinion focuserThe focuser holds accessories up to approx. The TS Photoline is a universal telescope for all areas of observation and photography and, of course, for astronomy. The contrast performance of the apo will surprise you in this field, too. The 72 mm APO lens, free from colour aberrations, allows magnifications up to approximately 200x. Observations of animals and the countryside with maximal image brightness even in twilight become possible, also observing extended nebula regions with nebula filters. Thus a gigantic magnification range with high field of view is available to you.īy using a 2" Paragon ED 35 mm eyepice and a 2" star diagonal, a true field of view of 5.7 degrees can be obtained, at 12x magnification. Observing with the Photoline 72 mm f/6 Apo:The generous working distance of the apo allows even using 2" eyepieces at full illumination. The optimal working distance from the T2-thread of the reducer to the sensor is 55 mm.Ĭorrectors and adapters are linked at the accessory recommendations, of course.Īstrophotographic results obtained with this telescope on AstrobinHere you can find some astrophotographs made with this telescope model: Link to Astrobin We recommend the corrector for DSLR cameras up to APS-C sensors and also for astro cameras with medium sized sensors. TSRed08-72 - TS corrector with focal length reduction - The corrector shortens the focal length of the apo from 420 mm to 331 mm and improves the focal ratio to f/4.74. The optimal working distance from the M48 connecting thread to the camera sensor is 55 mm, the working distance is extendable to 71 mm. The corrector offers full correction and a good illumination up to full-frame sensors. TSFLAT72 - Corrector without change of focal length - The corrector leaves the focal length at 432 mm and the focal ratio at f/6. A corrector is always necessary for maintaining good sharpness to the edge. This allows for trouble-free operation of our optional field correctors. Photography with the Photoline 72 mm f/6 apo:The apo has a large back focus of 135 mm from the 2" receptacle of the focuser. Despite very good mechanics, the apo is a true lightweight with only 2.18 kg, and with a length of only about 310 millimetres, the telescope has space even in the hand luggage. For this reason, we have equipped the telescope with a modern 2.5" rack and pinion focuser which can hold even heavy accessories like CCD cameras. The goal was to construct a compact and powerful telescope which is also attractive for the demanding astrophotographer. TS Photoline 72/432 mm Apo - a perfect travel scope for observers and photographersLead-managed by Teleskop Service, this high-quality Photoline apo with an FPL53 element from Ohara (Japan) was created.
