Optec 3" to SBIG STL Adapter for 3" Pyxis & TCFS-3 Focuser
Optec 3" SBIG STL adapter attaches these cameras to the 3" Pyxis Camera Field Rotator and the 3" TCFS Focuser. 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 Optec 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.
