OPTIONAL EQUIPMENT

Telescopes wheels kit

Fast coupling wheels with run-flat tyres and handlebars for easy transport of the alt-azimuth telescope.  No socket wrench is nedded.

Telescopes digital circles

The passive pointing system shows telescope´s position with high accuracy directly on the electronic planetarium maps (e.g. Sky Safari), which help the observer to point the telescope at any celestial object extremely quickly and easily. Also very useful when you want to use the telescope for educational purposes, viewing on a tablet or mobile phone allows you to check that the object is centered even when other people are observing. Consisting of 2 encoders with 10,000 steps and a Push-To control system that allows connection via Wi-Fi or Bluetooth to the phone. No visible cables, everything runs inside the telescope. Included in the kit is a pole with quick-release fix to the fork. (Table or phone is not included)
