As an addition to my collection of telescopic observations of Apollo missions en route to and from the Moon at http://astronomy.ua.edu/keel/space/apollo.html I recently received a before-and-after set of photographs of the Apollo 13 debris cloud from a 0.4m telescope at Mt. Kobau, British Columbia, taken by Frank Younger. It would give nice double-checks on both image scale and (especially) orientation if I could identify the stars in the background. Does anyone know a good way to work out the apparent position of Apollo 13 at the time of the explosion (03:07:53 UT on 14 April 1970) from Mt. Kobau (119d 30m W, 49d 07m N)? The "before" shot would also have been an observation very shortly after sunset so if I can ID the stars I can say something about their magnitudes and the sky brightness.
