The TS-Optics 76EDPH is intended for astrophotographers and nature photographers who also like to observe through a high-class apo. The refractor convinces by its solid mechanical workmanship and by its high-quality 3-element FPL53 lens. The image is free of annoying chromatic aberration. The 3-element corrector has been specially developed for this apo and produces a purecolor, corrected image field with 44 mm diameter, ideal for full-frame cameras. The fast focal ratio of f/4.5 allows short exposure times. The 76EDPH is a powerful and portable travel apo for astrophotography and observation.
Simply screw the 2.5″ image field corrector into the focuser. An M48x0.75 thread is available on the camera side of the corrector. The working distance from this thread to the camera sensor is exactly 55 mm. This is ideal for all astro cameras and DSLR / SLR cameras. The corrector also has a 2″ filter thread in front of the camera mount.
