TS-Optics 94 mm f/5.5 Triplet Apo Refractor Telescope

TS 94 mm f/5.5 Triplet Apochromat

The 94 mm apo with the fast focal ratio of f/5.5 is aimed at all amateur astronomers who are interested in a compact, pure color and fast apo. The triplet lens design includes two special ED elements. This provides an image that is free of disturbing chromatic aberrations even at higher magnifications. The optical performance of this newly developed lens corresponds to that of an FPL53 triplet. This lens is held in a CNC-milled mount, which is, of course, adjustable.

The refractor also convinces by its solid mechanics. The telescope is delivered with a 3" dual-speed rack and pinion focuser. Adjustment and bearing are separated from each other. This prevents tilting of the draw-tube when clamping and allows precise adjustment even with heavy loads.

Attaching the TS 94 mm apo to 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 saddle plates of mounts. We recommend an EQ5 class mount for the apo. Suitable dovetail clamps can be found in the accessories section. Furthermore, the dovetail also has a 1/4" photo thread.

The carrying handle is a truly multi-functional part

The handle not only makes mounting on a photo tripod easier, but 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 scopes, mini telescopes or red-dot finders.

Observation through the TS 94 mm f/5.5 apo
The pure color triplet lens naturally also provides an excellent basis for observation. The high-contrast image ensures a clear image even at daytime, for example when observing birds. The aperture of 94 mm also shows the crater landscape on the moon during the night or exciting details on the planets of the solar system. 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 diagonal mirrors.

Recommended correctors for astrophotography:

  • TSRED25DEL - the reducer fits directly to the M74x1 internal thread of the focuser. It reduces the focal length to 414 mm and improves the focal ratio to f/4.4. The working distance from the M48 thread is 55 mm.
  • TSFLAT2 - the corrector can be screwed (we will be happy to advise you) or it can be pushed in. The focal length is not changed. The working distance from the M48 thread of the corrector is 118 mm. The corrector is ideal for astrophotographers who like to use long accessories and who cannot manage with 55 mm distance.
  • WiflatM48 - the corrector is simply pushed into the 2" receptacle. The focal length is not changed. The working distance from the M48 thread is 55 mm.
