It now looks like this cloudy, wet spell won't let-up until next Wednesday or Thursday, meaning bright moon time. Planets, double stars, and narrow-band imaging time. An exception to the visual deep-sky washout is planetary nebulae. You can still get some good views of most of them with narrow-band filters, even on full moon nights.
