nouvelle Fornax ONE50

[vigon 187]

une nouvelle venue :

No meridian flip

 

*Built in absolute encoder (Haidenhein 25 bit)

 

*Built in MC5 controller:
MAIN FEATURES OF THE MC5

MC5 knows everything as the MC3, and has the following extra features:

Improved resolution: MC3 does 32x microstepping, MC5 does 256x microstepping.

Absolute encoders: MC5 can handle absolute encoders on both axis. The supported encoders are:

Heidenhain 25 bit / revolution models

Renishaw 32 bit / revolution models

Thanks to the encoders, the system is completely failsafe: It can know the exact position of the telescope even after a software problem or accidential restart. It prevents the accidential pier-hit.

MC5 can do closed loop tracking control. It gives you exceptional accuracy:

Tracking error within +/-0.5 arcsecond with Heidenhain 25 bit encoder

Tracking error within +/- 0.2 arcsecond with Renishaw 32 bit encoder

MC5 compatible with Ursa Minor Hand Controller: It has a 128 x 64 pixel graphic display with user friendly menu and an astronomical database with aprox. 50000 objects.

Firmware can be upgraded by the end user.

Astronomical database of the hand controller also can be upgraded.

Compatibility with most of the planetarium programs: MC5 has a dedicated ASCOM driver with parking and Meridian flip support.

Ursa Minor Pro planetarium program developed directly to fully support MC3 and MC5 controllers.

vous en pensez quoi?

C'est pas loud 30 kg pour cette grosse monture!

[Beagle 672]

Elle est beaucoup trop onéreuse pour 30kg de charge ...

[Pascal C03 4 055]

C'est beau ! Un vrai demi diapason...

 

On doit pouvoir assez facilement calculer le fondamental des modes propres de vibrations.

A utiliser à l'écart de tout souffle de vent, 4 voies...

à ce prix, je préfère la FORNAX 150 à environ 10000€ TTC pour 90kg de charge; et en plus elle est belle:

Hello,

 

Pour un truc aussi mastoc, j'aurais tablé pour un support de charge 2x plus élevé. C'est un avantage que de pouvoir éviter le retournement mais je la trouve pas bien positionnée au niveau des tarifs. Reste à voir sa réelle précision et sa fiabilité.
