Notes Seeing and transparency average (4.1 FWHM).  Clouds rolled in after only an hour or so, limiting my total exposure.  Not as smooth as I would have liked.  I tried string over the dew shield, to make the spikes.  I think I will go with thinner fishing line next time, as these were a little too thick.
