ASIAIRでガイドに使うのに最適なカメラと思います。カメラの性能を引き出すのにはそれなりのガイドスコープを用意するほうが結果的に良いガイド精度になる感じがします。Evoguide 50EDで使用中。

Quick delivery, good quality and small guider.

Es bastante ligera, por lo que va perfecta con un setup ligero, como la Sky Watcher Star Adventurer que solo soporta hasta 5kg. El guiado es muy preciso incluso en condiciones difíciles (a veces tomó fotografías en la azotea de un edificio que vibra ligeramente con El Paso de camiones, pero el guiado se mantiene dentro de lo aceptable). Excelente para equipo inicial-intermedio.

Everything in the ASI line usually just works and this one is no exception. Set up the same as all other ASI guide scopes. Works well in the ASI ecosystem and with the ASIAIR plus unit. Plug and go.
