Through the integrated corrector the field is also perfectly flattened and you will get perfect stars in the field right to the edge.\u003cbr\u003e\u003cbr\u003eAlthough this APO is optimized for Astrophotography, it also offers very good performance visually. The stars are pinpoint and are visible without any chromatic correction. The image stays sharp with exceptional contrast right up to 300x magnification.\u003cbr\u003e\u003cbr\u003eThe photographic 4\" Rack \u0026amp; Pinion focuser:\u003cbr\u003eThe CNC focuser is optimized for astrophotography and can handle a payload of up to 6kg and the travel of the focuser tube is carried out via rack and pinion. The construction of the drawer is similar to the Starlight Feather Touch and the mechanical stability comes very close to that of the Starlight Feather Touch as well. In addition to 2\" and 1.25\" receptacles, an M78x1 thread is also available for screw adaptations.\u003cbr\u003e\u003cbr\u003e\u003cem\u003eFeatures and advantages:\u003c\/em\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExcellent FPL53 triplet objective (glass from Ohara, Japan)\u003c\/li\u003e\n\u003cli\u003eIntegrated flattener with factory-set optimized distance to the objective for optimal sharpness in the field\u003c\/li\u003e\n\u003cli\u003e4\" CNC rack and pinion focuser with male M82x1 Connection thread - payload up to 6kg\u003c\/li\u003e\n\u003cli\u003eThe system is free from annoying reflections\u003c\/li\u003e\n\u003cli\u003eObjective and corrector are adjustable - but are already delivered optimally factory adjusted\u003c\/li\u003e\n\u003cli\u003eEach quadruplet APO is also checked by engineers before shipping and the optical system is also tested\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cem\u003eBefore you receive your TS Imaging Star 100 APO:\u003c\/em\u003e\u003cbr\u003eEvery single TS Imaging Star 100 APO is checked in the TS Optics technical department before its put into storage, in order to guarantee a consistently high product quality.\u003cbr\u003e\n\u003col\u003e\n\u003cli\u003eThe mechanics are tested, the focuser is optimally adjusted.\u003c\/li\u003e\n\u003cli\u003eThe objective is cosmetically checked and cleaned.
