Buongiorno a tutti.
Ho cercato informazioni su quest'ottica, ma non ho trovato granché.
Dal sito di TS:
The new Quadruplet SDQ APO with an aperture of 86mm and fast f/5.4 is an ideal Astrograph for mobile astrophotography with large sensors.
♦ 86 mm aperture - 464 mm focal length - f/5,4 f-ratio
♦ Modified Petzval Quadruplet design - the 2-element corrector is integrated.
♦ Image circle diameter: illuminated and corrected image field with 60mm diameter.
♦ No chromatic aberration across the entire field
♦ Free of reflexes due to optimized lens positioning and best possible lens coating
♦ The corrector is fixedly integrated - simply focus and you attain the ideal working distance
♦ High quality 3" Rack&Pinion focuser with micro gear reduction; suitable even for heavy cameras
♦ Precise fine focus for exact focusing - motor focus can be added later.´
♦ Camera-sided connection via M82x1 male thread and 2" extension tube
♦ 360° rotation and tilting mechanism are implemented
♦ Long backfokus of 95mm permits the use of diagonals for observing or exotical equipment
♦ We test each TS86SDQ on our optical banch. So you will have a tested telescope for maximum power under the stars.
Sembrerebbe carino, e personalmente lo vedrei come un possibile candidato all'upgrade (sostituzione) del mio TS65q.
Voi che ne pensate?
