The ZWO Nikon filter drawer allows you to easily connect ASI cooled cameras to Nikon F-mount lenses and has a built-in 2" filter holder.
It is compatible with all ASI cooled cameras with 17.5mm back focus distance (except ASI GT series): 1600/294/183/071/533/2600.
Note: Thread interface is M42 x 0.75 - While the included M54 male to M42 female adapter will in theory allow you to use the filter drawer with full-frame cameras such as the ASI2400/ASI6200, this is not recommended as the free aperture is smaller than the sensor diagonal of 43.3mm.
The spare filter holders for the M42/M54 filter drawers cannot be used with the EOS/Nikon filter drawers. Instead, use the dedicated EOS/Nikon filter holder.
If using non-ZWO filters, make sure they fit the measurements below:
