Abstract
We observed the corona with the potential for unprecedented spatial resolution afforded by a large stellar instrument at a prime site. An ambitious experiment involving the recording of 5 narrow-band 1024×1024 CCD images failed because of a last minute software change. Eclipses are unforgiving in this regard. However, a simple video camera was also fed by a beam-splitter pickoff with excellent results. This video tape, shown at the workshop,indicates how the field of interest was selected, concentrating on a large prominence at the NW limb. The role of seeing is evident; the smallest features detected were 0.6 arc-sec in size.
