Product description
Fornax 105 GoTo Mount with Absolute Encoderfor telescopes up to 90 kg weight

The mounts are manufactured in Hungary by experienced amateur astronomers and professional precision mechanics. The result are stable mounts with precise mechanics for astrophotography.

The mounts are now CNC machined , the worm and gear are made of bronze and stainless steel. The sensitive parts, such as worm, worm wheel and of course the motors, are sealed watertight and dustproof in the robust housing. This guarantees a long service life. The mounts can also be used well in observatories. The mounts do not react to temperature fluctuations and are practically maintenance-free.

The typical periodic error without autoguiding is very small at +/-0.5 arc seconds. It also occurs very slowly. A period is 7.5 minutes long. Any standard autoguider can guide the mount without any problems. Of course, the MC3 Goto control also offers the autoguiding interface.

"The Fornax 105 is a good mount, it has a great value for the money. It has no backlash, and reacts immediately to guiding corrections on both axes."

The MC5 GoTo controller with hand box
The control was developed by Ursa Minor for large mounts and is ideal for Fornax mounts. Of course, the control unit is delivered readily adjusted with the mount. About 50,000 objects are already contained in the database.
