The ZWO T2-1.25″ Filter Adapter is an accessory designed to integrate 1.25″ astronomical filters into imaging systems equipped with a T2 connection. It is suitable for astrophotography setups using ZWO ASI cameras, allowing the filter to be positioned directly in front of the sensor.
The adapter features an external M42×0.75 (T2) male thread and an internal M28.5×0.6 female thread, compatible with the standard thread used on mounted 1.25″ filters. The filter can therefore be screwed directly into the adapter, providing a simple and secure solution for using UV/IR Cut, light pollution, narrowband, or other 1.25″ astronomical filters.
