The filter drawer was developed by ZWO for Nikon F lenses and cooled ASI cameras with 17.5 mm working distance. You can now use your Nikon lens for astrophotography and use 2" filters for contrast enhancement or for L-RGB and narrow-band photography.

Features

• The drawer is compatible with all cooled ASI cameras with 17.5 mm flange focal length
• The drawer can also be combined with other astro cameras with 17.5 mm flange focal length or less. Shorter working distances must be compensated by the corresponding T2 extension.
• It is compatible with all 2" filters, including duo band filters, narrow band filters, IR cut filters, etc. The maximum height of the cell without the M48 thread must not exceed 7.5 mm.
• One 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.
• The magnetic holder ensures a precise fit of the filters and easy changing.
• The thread of the connector is M42x0.75. You can also use the adapter M42F-M54M to connect the filter drawer to a full format camera.
