Observations

Nov. 25, 2010, am

  • 100% clear, 2/5 transparency, 3/5 seeing

  • ED80 & LX10 mounted on Orion Atlas EQ-G (hand paddle)

  • backyard, Ottawa, Canada

  • terminator ~ 41 E

The forecast was for so-so seeing in the early evening, so I setup and went to bed with the intention of getting up around 3am when the moon was near the meridian and the seeing had improved.  The seeing was indeed much better at 3am, and so I proceeded to take the standard series of images.  I am finding that the single line polarizing filter should maybe only be used for  shots through the ED80 where the brightness is high.  Lately my zoomed in shots (ie. LX10) have been kind of dark, especially for phases far from full moon.  As a result, longer exposure times are required that in turn results in blurrier images.  I think I will try using no filter for future LX10 shots and all crescent phase shots through the ED80.

  • 100% clear, 3/5 transparency, 1/5 seeing

  • ED80 & LX10 mounted on Orion Atlas EQ-G (PC)

  • backyard, Ottawa, Canada

  • terminator ~ 35 E

A night of DSOs with the Mallincam, then wake up at 3:30am to get Moon with Toshiba.  Forecast looks like I should be able to get several nights of Moon in a row.  Tonight was so-so, with overall poor conditions but the occasional nice frame in there.  Posidonius and Theophilius were very prominent tonight.
