The TSA-120 is the second triplet apochromat in the TSA Series. Its superb color correction will provide high contrast images with pin point stars across the field. The compact size of 28 inches allows the TSA-120 to be easily transported to remote sites. The TSA-120 is a great scope for imaging. The TOA 35 flattener converts the 120 into an f/7.3 882mm flat field 2.6° instrument and the reducer changes it to an f/5.6 672mm
