Description: | A triplet design made to the specifications of GCS Astronomical. Scope cosists of a triplet cell comprised of high quality OK4 or OK6 extra low disspersion glasses in an air-spaced fashion. The optics are outstanding performers with strhl ratios in the high 90's and ptv wave errors generally in the 1/7th -1/8th wave. The scopes made for GCS include rotating focusrs and finders, a real convenience touch. Fit and finish is superb and the apochromatic optics are unsurpassed in their class, Flat field and tremendous contrast, this is a winner. Thanks, John. |
