Product description

High-performance flattener and reducer for the large William Apo refractors GranTurismo GT102 (only with 3" focuser), FluoroStar FLT132 and GranTurismo GT153. The flattener has a triplet APO design and is equipped with Ohara glass surfaces. It flattens the image field even for full-frame sensors and also acts as a reducer with a focal length reduction of 0.72x. This shortens exposure times and allows the image field to be illuminated up to full frame. By rotating it, the flattener can even be adjusted to the respective focus position. It is therefore suitable for various camera types, from (full-frame) DSLRs to CCD and CMOS.

Additional accessories such as filters, extension tubes or filter wheels can be easily combined with the William Optics flattener. It has a recessed M48 filter thread for mounting 2" filters.

The respective back focus is:

FLT132 = 63.4 mm

FLT156 = 60.8 mm

GT102 = 67.1 mm

GT153 = 60.4 mm

This corrects and illuminates an image field with a diameter of 44.4 mm.
