Baader Alan Gee Mark II Telecompressor (Flattener / Reducer) has been engineered specifically to work well with SCTs in a wide variety of visual and imaging configurations. The OD of the lens cell and spacers is 37.5 mm, permitting the AGII to insert up inside the baffle tube of 8" and larger SCTs. At last, you can use your SCT to produce stunning wide field views for single or binocular viewing or better still, sharp, wide, flat field photography at a fast focal ratio of f/5.9 (for a C8).
