We present a survey for bright Kuiper Belt objects (KBOs) and Centaurs, conducted at the Kitt Peak National Observatory (KPNO) 0.9 m telescope with the KPNO 8K Mosaic CCD. The survey imaged 164 deg2 near opposition to a limiting red magnitude of 21.1. Three bright KBOs and one Centaur were found, the brightest KBO having red magnitude 19.7, about 700 km in diameter, assuming a dark Centaur-like 4 % albedo. We estimate the power-law dierential size distribution of the classical KBOs to have index with the total number of classical KBOs with diameters larger than 100 kmq \ 4.2~0.3`0.4,equal to Additionally, we Ðnd that if there is a maximum object size in the Kuiper Belt, it4.7~1.0`1.6] 104.must be larger than 1000 km in diameter. By extending our model to larger size bodies, we estimate that Charon-sized and Pluto-sized classical KBOs remain undiscovered.30~12`16 3.2~1.7`2.8 Key words: comets: general È Kuiper belt È Oort cloud È solar system: formation On-line material: machine-readable table 1
