TS Optics 85 mm f/5.8 Imaging Star Quadruplet Apo with corrected image field
The astro community has been waiting a long time for an affordable apo astrograph for mobile use even with larger camera sensors. The great success of the TS-Optics Imaging Star 100 mm Quadruplet has encouraged us to develop a telescope with the same properties for mobile use. The Imaging Star 85 Quadruplet was recalculated and designed entirely new. the result is a very light and portable astrograph which illuminates and also excellently corrects an image circle of about 50 mm.

With only 4 kg weight and a transport length of only 36 centimetres (dew cap retracted), the apochromat is well suited for air travel.

Despite the apo is optimized for astrophotography, it can also be used for observations with 2" star diagonal mirrors, due to the generous back-focus. The very fine chromatic correction of the FPL53 triplett lens allows magnifications up to approximately 200x without annoying chromatic aberration.
