ZWO Filter Drawer for manual filter change in seconds
ZWO offers with the M54 filter holder a very advanced drawer with many useful product features. Especially astrophotographers, who do not want a big and partly heavy filter wheel, find an exciting alternative with this filter drawer. Despite the compact and above all lightweight design, this filter holder does not have to sacrifice stability and accuracy.

ZWO has developed the filter drawer for the full frame cameras ASI6200MM and ASI6200MC Pro. The drawer can also be combined with other cameras with M54x0.75 connection.

A reduction adapter to M48x0.75 is also included. This allows the filter drawer to be adapted to the corresponding connections.
The optical path length is only 20 mm. The adaptation is easy and can be done with standard adapters.
The filter holder snaps magnetically into place, thus guaranteeing exact positioning of the filter.
A "Lock Screw" additionally fixes the position of the drawer for fixed adaptations where no filter change is planned.
Thanks to the open design of the drawer, the filter can be easily inserted or removed.
The drawer is round and very compact, so it can also be used in front of the optics, for example in Hyperstar systems or Celestron RASA.
A filter holder for 2" filters is included.
Important for the purchase of further filter holders: Only the linked filter holder fits, older versions are not compatible.

"Der Filterschieber verfügt über eine magnetische und mechanische Fixierung. Die magnetische Halterung fixiert ohne Frage den Schieber im Halter, jedoch nicht in Richtung der optischen Achse. Ein Kippeln des Filters bewirkt jedoch eine Verschiebung des Bildes wie bei einer adaptiven Optik. Die zusätzliche mechanische Kugelrastung könnte das Problem entschärfen, wirft aber neue Probleme auf: -Werkseitig so locker, dass die Schraube fast rausfällt. Keinerlei Schraubensicherung oder Justage -Bei dem Versuch, die Kugle-Vorspannung optimal einzustellen kommt man schnell an Grenzen. Stabiler Sitz bedeutet leider auch große Auszugkraft beim Filterwechsel. Das Problem hat ZWO bei seinem alternativen Filterhaltern besser gelöst. Leider mit anderem Gewinde."
