TS 76EDPH 6 element flat field apochromat
The TS-Optics 76EDPH is aimed at astrophotographers and nature photographers who also like to observe through a high-quality apophoto. The refractor convinces with its robust mechanical processing and its high-quality 3-element lens. The 3-element corrector has been specially developed for this apo and creates a well-corrected field of view with a diameter of 44mm, ideal for full-frame cameras. The fast f/4.5 aperture ratio allows for short exposure times. The 76EDPH is a portable, fast travel apochromat for astrophotography and observing.
Connecting cameras to the apo:
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. Matching T-rings can be found in the accessories section. The corrector also offers a 2" filter thread on the front of the camera mount. camera.
Attaching the TS 76EDPH to photographic mounts and tripods
The CNC clamp has a GP and EQ5 style dovetail bar at the base. You can attach the telescope to suitable quick-disconnect mounts and travel mounts, such as the Skywatcher Star Adventurer. Matching dovetail clamps can be found in the accessories section. In addition, the rail also has a 1/4" photo tripod thread. Therefore, the apo fits directly on any photo tripod, such as a telephoto lens.
The carrying handle is a true multifunctional piece.
The handle not only makes it easy to mount on the photo tripod, but is also the basis for future adaptations. The handle has a slot and a 1/4" photo tripod thread. You can attach a ball head to it, for example, and mount a second camera in parallel. Next to the carrying handle is a finder shoe for finder scopes, mini scopes guide or direction finders.
Observation by the TS 76EDPH
Of course, the colorless triple lens also offers an excellent base for observation. The high contrast image also ensures a clear image underground, for example when bird watching. The 76mm aperture also shows the crater landscape on the moon or exciting details on the planets of the solar system at night. Many thousands of deep sky objects are also within range of apos. You can use 1.25" and 2" accessories, such as 2" star diagonals.
