Optec 1.67" STL Mounting Plate - SBIG STL without Filters
The NextGen 3" CCD Camera Mounting Plates fit onto the male Optec-3100 dovetail (3.1" diameter) on the camera side of the NGC 316 NextGEN 3" telecompressor lens system. The tube length of each mount is cut to match the proper back-focus for a particular camera/filter wheel combination.
This STL mount has a tube length of 1.67", which is the proper mount when attaching the NGC 316 to an SBIG STL camera without filters using the 4-bolt mount.
