Tonight I finally obtained an image of C/2011 L4 (PanSTARRS), after all these cloudy evenings. There was a gap in the cloud for about 30 minutes which I exploited. The comet is going behind a nearby fir tree during the course of the exposures, obscuring the frame on the right hand side.
Slightly later I observed it visually from an upstairs window using 10×50 binoculars, but it was only just visible in those, looking much fainter and more diffuse than when I last saw it on March 14. (Click to enlarge)
