Guide rates are often set at 0.5x sidereal rate because that ensures that the mount won't move fast while you are exposing. However, we only ever adjust via guiding between exposures so it seems like we shouldn't need to worry about this and instead could guide at 0.9x (the maximum IIRC).

Not uncommonly seeing differences of ~20-30 arcseconds, which can be 2-3 seconds of adjusting at 0.5x rate. Looking to get this lower.

@joshwalawender any practical reason we shouldn't adjust guiding at the maximum allowable?
