The K10D and K20D didn't have sensor rotation as part of the SR system, so it wouldn't have worked as well for astrophotography on those cameras. (The motion of the stars on the sky varies from pure rotation at the celestial poles to pure translation at the celestial equator.) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
