I seem to be getting a break from Arizona's monsoon season. While it's been clear for the past week, there's also a full moon in the sky. No worries. Time to collect some H alpha data! I can collect the other channels when the moon slims down again, provided I a get another break in the weather.

Fingers crossed.
