Optec 1.44" T-Thread Mounting Plate - SBIG ST-10 and CFW10
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 T-mount has a tube length of 1.44", which is the proper mount when attaching the NGC 316 to an SBIG ST-10 CCD camera and has the CFW10, 0.25" front plate and D-block.
