The Tecnosky 102/700 FPL-53 Doublet represents something of a bargain in the 4" refractor class. The entry level FPL-51 version has always proved itself a popular beginners scope. With superior glass types and a quality 2.5" focuser, the 102 FPL-53 Doublet offers near perfect colour correction and is suited to to both observing and a wide range of imaging tasks. Its F7 focal ratio make it suitable for use as a solar scope when fitted with a suitable ERF and rear mounted etalon. The aluminium tube is fully baffled and fitted with a 2.5" Rack and Pinion focuser with 1:10 fine focusing.
The Tecnosky 102 represents an outstanding value scope for beginners or even seasoned astronomers. Its compact dimensions make it easy to transport. Its light weight does not place heavy demands on a mount. Its 102mm aperture minimises the effects of seeing yet it is large enough to gather significant light to see all but the faintest of objects. Its excellent colour correction also make it usuable at higher magnifications for planetary observing. It is truly an excellent multi-purpose scope at a very appealing price.
For imaging use we recommend use with either the 2.5" Flat FIeld Corrector or the APM M63 Reducer. The latter turns the scope into 525mm FL, F5.25 Astrograph. Our UXF motorised focuser kit is an ideal way to complete the imaging package.
Thanks to its compact size and low weight, the 102 works well with small manual mounts and medium sized EQ mounts.
As with all telescopes supplied by Astrograph, the 102 is supplied only after careful inspection.
