MOUNTING ADAPTERS for TCF-S3
#17807 - 3-inch to AstroPhysics 2.7-inch mount. This mounting adapter offers
the popular female side of the AP thread to attach accessories.
#17804 - 3-inch to 2-inch reducer bushing. This adapter allows all of the 2-inch
size camera mounts and other 2-inch adapters to fit the TCF-S3.
#17805 - 3-inch to Optec 2.4" mount. 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.
#17806 - 3-inch to STL camera mount. The STL line of cameras from SBIG support
some of the largest CCD chips available. The usual T-thread mount adapter does
not have enough clear aperture to accommodate these chips without vignetting.
This adapter uses the 4-bolt holes in the front plate of the STL to secure the
mount giving a full 2 inches I.D. close to the CCD.
#17813 - 3-inch to Starlight 3.5-inch focuser model 3545 adapter mount with
male thread. Allows accessories designed to scew on the back of the Starlight
focuser to fit the TCF-S3.
#17816 - 3-inch to 3-inch extender tube allows cameras and other accessories
to be mounted past the limited 1-inch focus travel of the TCF-S3. Grooves are
cut every 0.3 inches into the extender to engage the three locking screws in
the TCF-S3 drawtube. Extension range is from 1.0 to 3.1 inches in 0.3 inch steps.
#17811 - 3-inch to Optec 3.6-inch mount. This mount has a 3-inch O.D. barrel
on one side and a 3.6-inch diameter with dovetail on the other. It will allow
any of the 3-inch line Optec instruments to fit the 3-inch I.D. drawtube.
