Fornax 100
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. |
