This is the latest incarnation of the former Fornax 150 mount. The New Fornax 150 comes with much strengthened and improved wormbox that makes it an even more precise mount. The new housing of the worm drive is stronger and it has got an extra unit that holds it in exact position, eliminating any sideway movement that could have occured in earlier versions when changing direction under heavy load.


-No backlash
-Accuare unguided tracking
-Robust body
-120 kg payload capacity

Robust Body 


Fornax Telescope Mounts are a series of German Equatorial mounts for precise positioning and tracking large telescopes. These are available in various payload capacities: 50kg, 100kg, 150 kg and 200 kg (the latter one is coming soon). The Fornax 150 telescope mount is a heavy duty German Equatorial mount for precise positioning and tracking extremely large telescopes up to about 100 kg. Although there are examples of use of even heavier telescopes up to 150 kg, the recommended maximum load is about 100 kg for this telescope mount when used for imaging.

High accurate tracking

The mechanism of this extremely sturdy mount is being made of aluminium alloy, cast aluminium, bronze and stainless steel. The worm and the electric motor are located in an enclosed, sealed space (waterproof and dust-proof), making it less sensitive to dust and temperature fluctuations, and is practically maintenance free. Thanks to the ingenious solution of the inner drive mechanism this telescope mount doesn't suffer from any backlash. Typical periodic error (when not guided) is less than +/- 6 arc seconds (one period on the worm gear is 7.5 minutes long!) When using a TDM (Telescope Drive Master), this can be reduced to below +/-0.5 arc seconds. (TDM is an alternative solution to guiding.) When using auto guiding, the mount reacts immediately, so corrections are very fast and completely free of play. This is the ultimate solution for astrophotography with a high quality/price ratio.

Due to its weight and size this model is designed for observatories, not exactly a transportable model.

URSA MINOR - MC3


This is a versatile telescope controler electronics. This equipment is the optimal choice for all medium to large telescope mounts. It controls the The built-in stepper motors of the mount, allowing the object positioning and tracking. To use this device, you should connect it to a computer, which is running planetarium software (eg, Ursa Minor Pro) or use a hand-held remote control. The device can be easily adapted to most astronomical telescope mounts. With the included (free download) software you can adjust the gear ratio, the current level of the motors and many other parameters. Thanks to the versatile configuration options the motors are running very fine. This capability makes it especially useful for useing at very good atmospheric conditions where the image in the telescope is very sensitive to any kind of small errors.
