Optec 3" to IFW Front Mount for the TCF-S3 & Pyxis 3"

In order to accommodate the IFW filter wheel system, this short adapter will rigidly attach the IFW to the 3-inch port of the TCF-S3. Since the IFW uses 2-inch or 50 mm filters, it cannot be attached in front of the TCF-S3 as it does for the 2-inch TCF-S.
