Dovetail-bars and -clamps - the “Missing Link” for your equipment

schiene_v Modell V (EQ) – Celestron, Skywatcher

Mounting accessories connect telescope and mount - be it for a permanent setup or to make quick changes from one instrument to the next possible. We can offer several bars and plates, so that you can adapt almost every telescope:

  1. Modell V (EQ) bars and clamps - for Vixen / Celestron / Sky-Watcher / Synta and many more. (Base width of the bar's prism: 44 mm. Bar width of the side facing the telescope: 70 mm)
  2. Modell Z bars and clamps - for Zeiss / Astro Physics (Base width of the bar's prism: 40 mm. Bar width of the side facing the telescope: 70 mm)
  3. Modell 3" bars and clamps - for Losmandy / Astro Physics (large) / Celestron (large) (Base width of the bar's prism: 76 mm, equals 3". Bar width of the side facing the telescope: 105 mm)
  4. Special lengths up to 6.000 mm long V, Z and 3" bars

The matching accessories

All of our dovetail bars do have integrated, deepened marking lines over the whole length of the bar. They mark the exact center line of the bar, as well as the seperation of the screw holes of Celestron telescopes and Astro-Physics mounting rings, so that you can easily drill the matching holes. The V and Z bars do have integrated offsets for the bases of most chinese mounting rings, so that they match the bars perfectly. Nevertheless, the bearing surface is hyperbolic on the telescope side, so that the bar will fit tightly for all telescope diameters between 120 and 450 mm.

schiene_z Modell Z – Zeiss, Astro Physics

The 3" bars provide three of these offsets, so that they match the base widths of the most common mounting rings. Nevertheless, the bearing surface is hyperbolic on the telescope side, so that the bar will fit tightly for all telescope diameters between 160 and 600mm.

All three bars have got a central, 10.5mm wide pit on the upper and lower side. Here a screw head with up to 10mm wide fits into it, so that the head's surface is not visible above or below the bar (Only exception: The 3" bar is flatter on the upper side, so that a screw's head would poke out of the central pit. This was done to keep the bar's profile as flat as possible, for a short distance between telescope and mount.


Special lengths up to 6000mm length

We offer all of our V, Z and 3" bars also in custom lengths of up to 6000mm, optionally also with black anodizing. At an additional cost, we can also provide up to four additional, simple boreholes, as long as our workshop has got the time to do it and the holes are placed outside of the central pit. To do so, we need a precise drawing including the desired diameters of the holes (better too large than too small), or a contact print. For this, you simply press a piece of thick packaging paper against the telescope's tube and trace the holes through the paper.
