CCD images of Makemake (2005 FY9), the second largest Kuiper Belt Object (KBO), were taken with a 14-inch telescope during the summer of 2008. The position of Makemake was found by comparing its position on the frames to UCAC2 stars in the frame. Observations were limited by the tracking capabilities of the telescopes and atmospheric limitations. The average right ascension offset from the ephemeris was found to be 0.0134 0.3394 arcseconds, and the average declination offset was found to be -0.3855 0.4634 arcseconds. It is possible to do KBO astrometry with small telescopes, however several hundred frames are required to equal the quality of observations on larger telescopes.
