The moon when I want to do some imaging.
Light pollution (from street lights and from Charlestown which is out of my direct line of sight but still spoils my sky ,,, only 2 km away).
Dills with headlights who shine them right in my eyes when at the Valentine park.
My neighbour's back light (.... not been on lately as he's back in the loonybin).
Clouds.
Wind.
