![]() 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)
