IDAS/ZWO Filter Holder Available

Now the adapters are commercially available. The set includes two pieces – a lens adapter and a camera adapter. The key is the total light path is fully optimized for IDAS filter thickness. So this is ready to go without worrying about light path shift by a filter glass thickness.


Clockwise from upper left : M42, M54, Nikon F and Canon EF

You can select one of each combination among followings.

Camera interface : M42(T-thread) for APS-C or smaller,  or M54 for full frame

Lens interface : Canon EF, Nikon F or Pentax K

Filter size : IDAS 52mm or 48mm

The set price : $195.00

If my understanding is correct, ZWO cameras have no IR blocker inside body. So this kind of setup is essential, especially for regular camera lenses. And also today’s high quality lenses are so sensitive to the back focus distance. The right light path is critical to achieve the native optical performance.
