In addition, there are screws for adjusting the focus of the focuser, but I did not need to touch them - the focuser walked well, leaving the center of the field of view from the axis was not observed, and the helical gear / rack provided accurate positioning of the receiver (eyepiece), without backlash, delay and lateral displacements. On the focuser case (white) there are two pairs of plugs for attaching the finder and / or guide shoes. Measured aperture 102 mm - without internal cuts. Interestingly, the laser beam test showed that the light scattering is greater on the second (inner) lens, that is, the quality of the ED glass of the front component is really high. ![]() Review from an happy customer - TSAPO102f7The first lens is positive made of ED (FPL53) glass. Astrophotographic results obtained with this telescope on AstrobinHere you can find some astrophotographs made with this telescope model: Link to Astrobin Technical InformationTeleskop-Service has collected a lot of helpful information about refractors and provided it in English as a PDF file: Infos and Manual for Refractors The illumination and correction is suitable for all sensors up to full format.Īstrophotographic results obtained with this telescope on AstrobinHere you can find some astrophotographs made with this telescope model: Link to Astrobin ![]() The corrector is screwed to the M68 connection thread. For a camera with 55mm flange focal length, simply use an M48 tuning ring with 1mm height. The working distance from the M48 thread is 56mm. ♦ TSRed379 - 3" photoline reducer and corrector: This 0.79x corrector reduces the focal length to 564mm and increases the speed to f/5.53. We are happy to help you with the adaptation. The working distance from the M48 camera thread is 55mm. It is screwed directly to the M68x1 female thread of the focuser with the adapter # M68a-M63i. This corrector does not change the focal length. For this, we offer the following choices, the correctors are linked in the accessories section. ♦ CNC tube rings and GP style dovetail bar in the scope of deliveryĪstrophotography with the TSAPO102F7:The Photoline SD-Apo 102mm f/7 is fully suitable for astrophotography, however, like with any fast refractor, the field has to be corrected so that even the stars at the edge are nicely round. ♦ Internal baffles and very good internal blackening for contrasty images ♦ M68x1 thread (female) for threaded adaptions and 2" / 1.25" for pushed adaptions ♦ 1:10 speed reduction for precise focusing. ♦ Overdimensioned draw tube for full illumination even with full-frame format. The support is decoupled from the adjustment of the draw tube. ♦ Ball bearing supported focuser with rack & pinion adjustment. ♦ 102 mm f/7 FPL53/lanthanum glass lens for an image free of chromatic aberration Thereby the performance of the lens can be fully implemented photographically or visually.Īdvantages and features of the PhotoLine 102 mm f/7 apo: Very fine mechanics guarantees joy with the telescope and universal application capabilitiesThe new PhotoLine 102 mm apo offers, besides a lens of the latest generation, also a mechanical equipment which leaves nothing to be desired. ![]() This means that the fast refractor is not only very well suited for astrophotography and wide-field observation, but also for moon and planets. Even at highest magnification, the image remains free from distracting chromatic aberration. By combining FPL53 (Ohara, Japan) and a lanthanum glass element, a chromatic correction is achieved which matches the one of an FPL53 triplet - with significantly quicker cooling down. TS-Optics PhotoLine 102mm f/7 Dublet FPL53 ApoThis apochromat from the PhotoLine series from Teleskop Service offers very good performance in any application area. ♦ CNC tube rings and GP style dovetail bar are supplied ♦ M68x1 thread (female), 2" and 1.25" receptacle are available ![]() ♦ One of the best 2.5" focusers in its class, with 360° rotation, ball bearings - adjustment via pinion - with dual speed gear - motor focus can be retrofitted ♦ Internal baffles for a more contrasty image ♦ Shorter cooling time than with triplet lenses, thus quicker operation possible ♦ Image free of chromatic error due to "Extra-Low-Dispersion" FPL53 apo element from Ohara (Japan) and Lanthanum element - with this, we achieve a better chromatic correction than comparable apochromats with doublet lenses. ♦ Adjustable doublet in temperature compensated cell ♦ Aperture 102 mm / focal length 714 mm / focal ratio f/7 This Photoline 102/714 mm apochromat has a great FPL53 / Lanthan objective for very good color correction and one of the best 2.5" R&P focuser in this class.
