About

A four-element telecompressor corrector designed specifically for the 155 mm f/7 StarFire — not the same optical design as the other QUADTCCs — giving pinpoint stars to the corners of a full-frame 35 mm sensor. It needs a 3.5-inch connection to the telescope, so an EDF's 4-inch focuser takes the ADA435 adapter and an EDFS's 2.7-inch focuser must be upgraded.
