Telecompressor - This adapter allows you to use the Telecompressor (27TVPH) with your Pentax 6x7 camera. Your image circle will be approximately 2" fully illuminated. We suggest that you review the exploded diagram (PDF file) showing the telecompressor with a variety of accessories.

To couple scopes that don't need a field flattener to the Pentax 6x7 - Thread directly onto your Astro-Physics 2.7" focuser, 4" focuser, or any focuser drawtube that measures 2.740" I.D. with 24 TPI in order to use a Pentax 6x7 without a field flattener. This is appropriate for our older 6" f9 and 6" f12 scopes, however, a field flattener is needed for the shorter focal lengths to obtain the best results.

Please note: This adapter uses the Pentax 6x7 INNER bayonet and will only attach to a Pentax 6x7 camera. This adapter can NOT be used with our CCD adapters (A1260, A1261, A1262, A1263, & A1265); with our STL series adapters (ADA671 & ADA672); or with our SLR camera adapters for the field flatteners (67RLEOS, 67RLNIK or 67RTxxx).
