The compact size, less than 23° with the lens shade retracted, makes the TSA-102 the perfect airline ready apochromat. The TSA-102S is great for eclipse expeditions or transport to remote sites.

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 360° 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.

The TSA-102S is a compact, high quality, apochromatic, versatile Takahashi, made for the refractor enthusiast who wants a very high quality instrument in a relatively compact package.
