A great deal smaller and dimmer

I have managed to get readings for
seven nights in a row.
Most unusual weather

shot of M101. Unfortunately the warm temperature
today with rain in the
afternoon has caused condensation somewhere in the equipment!

My previous magnitude estimates were
very different from the AAVSO values, so I refined my technique.

the stars. Previously I had left them at the default settings.
