The entire focuser can be rotated through 360 degrees as an aid to finding a comfortable eyepiece position or camera orientation during photographic compositions. The drawtube has an engraved millimetre scale which is extremely useful for reproducing approximate visual and photographic foci.

The superb brass helically-cut rack-and-pinion focuser has zero backlash, and one full rotation of the 2:15 ratio fine focusing wheel advances the drawtube 2.2mm over a total travel of 60mm. It looks and feels like robust travel-mate - first impressions subsequently confirmed during my recent round-the-world trip. The machining and anodising is first rate, quality fittings are used throughout and the whole instrument exudes an air of refinement. Telescope Service has garnered a well-deserved reputation for the build quality and optical performance of its ED doublet and triplet refractors, and the TSAPO60 is no exception. Sans star diagonal, the instrument with tube ring, finder base, dovetail and a 2-inch to 1.25-inch adapter tips the scales at a very modest 1.75 kg. The tube collar has two opposing faces machined flat with three threaded mounting points on each face, so the supplied 10cm Vixen-style dovetail bar can be attached to either side. However, one could use a much smaller bag (such as a large DSLR camera case) for a minimalist TSAPO60 setup.īeing so short, the TSAPO60 eschews conventional tube rings in favour of a 5cm-wide CNC tube collar with a Vixen-style finder base.
However, one could use a much smaller bag (such as a large DSLR camera case) for a minimalist TSAPO60 setup.As befits a grab-and-go instrument, the TS Photoline 60mm f/5.5 FPL53 apo (to give it its full name) is supplied in a padded soft case measuring 47cm x 29cm x 15cm that contains ample foam cut-outs for additional accessories like star diagonals, field flatteners and eyepieces. But when total luggage allowances rarely exceed 23 kg, how does one choose a suitable telescope to take to far-flung dark skies? Fortunately for globe-trotters concerned about optical size and weight, Telescope Service in Germany has made that decision a whole lot easier with the introduction of the TSAPO60 - a compact and very versatile photo-visual 60mm f/5.5 (330mm focal length) ED refractor.Īs befits a grab-and-go instrument, the TS Photoline 60mm f/5.5 FPL53 apo (to give it its full name) is supplied in a padded soft case measuring 47cm × 29cm × 15cm that contains ample foam cut-outs for additional accessories like star diagonals, field flatteners and eyepieces.

A 5cm-wide CNC tube clamp with a Vixen-style finder base has three threaded mounting points on each opposing face, so the supplied 10cm Vixen-style dovetail bar can be attached to either side. Its 2-inch push-fit drawtube rack-and-pinion focuser has a 2:15 reduction gearing for precise focusing. With its dewshield retracted and threaded 35mm tube extension removed, the 60mm aperture, 330mm focal length TSAPO60 refractor is just 23cm long.
