  The canonical observation mode for IACT gamma-ray observations employs four
discrete pointings in the cardinal directions (the "wobble" mode). For the
VERITAS Observatory, the target source is offset by 0.5-0.7 degrees from the
camera center, and the observation lasts 20 minutes. During January/February of
2011, the VERITAS Observatory tested a new "orbit" observation mode, where the
target source is continuously rotated around the camera center at a fixed
radial offset and constant angular velocity. This mode of observation may help
better estimate the cosmic ray background across the field of view, and will
also reduce detector dead-time between the discrete 20 minute runs. In winter
2011, orbit mode observations where taken on the Crab Nebula and Mrk 421. In
this paper we present the analysis of these observations, and describe the
potential applications of orbit mode observations for diffuse (extended)
sources as well as GRBs.
