Fast delivery

Fast delivery, builing it was fun. And good support with problems. Testing in the next days.

Sehr gut

Der Astrotracker erfüllt sehr gut seine Bestimmung. Er ist sehr gut gefertigt und läuft völlig geräuschlos (sehr leise). Die Unterstützung der Polausrichten ist sehr hilfreich und einfach durchzuführen.
Leider konnte ich, auf Grund des Wetters noch keine Aufnahmen machen.
Was mir gut gefällt: Er funktioniert auch einwandfrei mit einer 5V Powerbank. Somit bin ich mit einer DSLR und Astrotracker im Feld Netzunabhängig.
Danke an Astrotracker Entwickler !!!! :-))
