[Aavso-photometry] Short-Exposure Photometry

[Dan Kaiser]

This discussion comes at an opportune time.  I have been giving much
thought to observing a transit of exoplanet HD 209458b.  With my 14" SCT
it is almost too bright.  I have concluded I will try with a B filter,
which will cut down a lot of light and hopefully allow exposures longer
than say 8 seconds.  It will also dim my guide star which could be a
problem.

A heads up to anyone in the eastern  and midwestern americas wanting to
attempt this challenge.  HD 209458b will be well placed this friday
night/saturday morning with a transit beginning at 5 hrs UT.  Weather
permitting I will be there.

I'm also looking forward to Tim Castellano's Transitsearch talk at the
meeting next week.
