Hence, if one had a 12th magnitude object (normally an easy target for the HUT TV), but it unfortunately had a 5th magnitude star within a few arcmin, one would have to set the camera for the brighter object, and use a "guide star locate" to blindly place the object in the slit. On the other hand, if a field contained a 9th magnitude star, and the object and/or several potential guide stars in the 13-14th magnitude range, one could set up for the fainter targets. (In this case, the bright star would "bloom" somewhat on the camera, and could not be chosen as a guide star because it would be saturated, but it would not cause a "camera safety" concern.)
