We have observed a sample of FIRST radio sources selected for being within an 15'' < r < 25'' annulus surrounding a 11 < V < 12 magnitude guide star with Tonry's OPTIC orthogonal transfer CCD camera. This device provides an effective tip/tilt capability by actively shifting the charge on the CCD during an integration rather than actively moving a mirror. In the best conditions we obtained 300 second R band images whose psf's had FWHM of 0.4'' on the UH 88 inch telescope. We will present detections down to R=23.7, images, and VLA radio maps of the sample. The sample provides excellent candidates for AO studies on large aperture telescopes. This work is partially supported by NSF grant AST-0098349.
