TS 94EDPH 7-Element Flatfield Apochromat
The TS-Optics 94EDPH is aimed at astrophotographers and nature photographers who also like to observe through a high-class apochromat. The refractor convinces by its solid mechanical construction and its high-quality 3-element APO lens. The image is free of disturbing chromatic aberrations. The 4-element corrector has been specially developed for this Apo and produces a color-corrected image field with a diameter of 50 mm, ideal for full-frame cameras. The fast focal ratio of f/4.4 allows short exposure times. The 94PH is a fast apo for astrophotography and observation.

Camera connection to the apo:
Simply screw the 2.5" 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. Suitable T-rings can be found in the accessories section. The corrector also offers a 2" filter thread in front of the camera mount.
Attachment of TS 94EDPH on mounts and photo tripods
The CNC tube ring has a GP and EQ5 style dovetail bar at the base. You can attach the telescope to the corresponding saddles of mounts and travel mounts like the Skywatcher Star Adventurer. Suitable dovetail clamps can be found in the accessories section. Furthermore, the dovetail also has a 1/4" photo tripod thread.
The carrying handle is a real multi-functional part
The handle not only facilitates mounting on the photo tripod, but it is also the basis for further adaptations. The handle has a slotted hole and a 1/4" photo thread. You can attach a ball head to it and mount a second camera in parallel, for example. Next to the carrying handle is a finder shoe for finder telescopes, mini guide scopes or sights.
Observation through the TS 94EDPH
Of course, the pure color triplet lens also provides an excellent basis for observation. The high-contrast image also ensures a clear image at daytime when observing birds, for example. The aperture of 94 mm also shows the crater landscape on the moon or exciting details on the planets of the solar system during the night. Many thousands of deep-sky objects are also within the range of the apo. You can use 1.25" and 2" accessories, such as 2" star diagonals.
