Complete TSA-102 system. Package includes TSA-102 refractor, EM-11 Temma-2 Jr. GOTO mount, tube holder, 7x50 finder, finder bracket, tripod, 18mm LE ocular and 1.25" Takahashi diagonal with compression ring.

Not only is the TSA-102S a great visual instrument, it can be converted into a flat field f/7.84 or an f/5.98 wide field imaging platform for a CCD camera or digital SLR. The addition of the optional camera angle adjuster allows the image to be rotated 360ý without loss of focus. The camera angle adjuster is also very handy for visual applications to position the ocular or bino viewer in the best most comfortable position.
