Last but not least TS offers a free test on their optical bench before shipping each refractor very carefully packed to the customers.Ī large refractor needs an intelligent dimensioned focuser. Finally, the TS 130 APO uses an air-spaced triplet configuration for full color correction. A good possibility as most TS modern Photoline APOs are based on FPL-51 & 53 Ohara glass. ![]() The glass material used for the other mating element lenses is not specified.įorum-members claim the scope has the same specifications as if it used FPL-51 glass manufactured by Ohara GmbH in Japan (Sales offices in USA & Germany). One of the TS 130 mm high-quality lenses is made of Extra-low Dispersion (ED) FK-61 glass. This refractor has an aperture of 130 mm, combined with a 910 mm focal length, which gives an f 7.0 ration so it can be used for both planetary and deepsky imaging. longer focuser).īasically, the quality of any apochromatic refractor depends on three items: (1) aperture, (2) glass quality and (3) lens configuration. An aluminium storage/transport case is included, which is replaced by a quilt padded bag whenever the APO doesn’t fit due to custom accessories (e.g. The OTA comes with CNC machined tube rings (Computer Numerical Control refers to the automatic operation of machine tools) which have a base to put a finder of guiding scope in place. Of course it’s a well designed tube with internal baffles prevent straylight. ![]() The metal tube doesn’t look a fancy as carbon-fiber OTAs but allows a faster cool-down time, important for this size refractors. Transport dimensions are 68 cm tube length (dewcap retracted). The white robust tube weighs 10.5 kilograms and the dew cap screws in a retractable metal dew cover with large locking screw. First impression shows a high quality well manufactured refractor with a tough look & feel. The TS 130 mm f 7.0 APO-refractor sits in TS’ new photoline telescope series, aimed at both beginner & advanced amateur-astronomers doing AP. With a growing urge to perform some Astro-Photography (AP) I decided to go for an Apochromatic refractor with minimum aperture of 130 mm in order to use it on a Celestron German Equatorial Mount (CGEM) capable of carrying 18 kilograms.Īlthough the Celestron CGEM (capacity 18 kilograms) worked fine on the Moon, astro-photography of Deep Sky Objects requires a more sturdy mount, so nowadays the TS 130/910 sits on a CGE mount (capacity 45 kilo). I have a keen interest in astronomy for almost 40 years and have mainly been “visually” observing the Moon & planets using refractors. As a new Stargazers lounge use I would like to share my review of the TS 130/910 Apo-Refractor (with 3” linear power focuser)
