Filthy bird feeder exposed through digiscoping

Today's bird picture is so much better than previous photos of backyard birds, I can clearly see now that we need to steam-clean the filthy feeder. Probably just replace it.
 

That photo and the photo below were taken with a Nikon Coolpix P300 mounted to a Nikon ED50 fieldscope. The tree was about seventy-five yards away.
    Neither photo is quite optimally sharp1, because I focused the fieldscope looking at the camera's monitor rather than looking through the fieldscope's eyepiece (after swinging the camera platform away from it). I'll do it properly the next time I go digiscoping.


In the course of becoming more familiar with the P300, I discovered that it can also take panorama shots, either 180- or 360-degree. A fluid-motion video tripod lends itself well to this application. Set the vertical plane to stiff and slowly rotate the camera 180 or 360 degrees2. The result is a very wide photo, which displays slowly in the camera monitor with photo height equal to monitor height—displayed from left to right, or right to left, depending on which direction the camera was rotated for the shot.
    Another thing I discovered is that it's easy to lay the P300 down someplace and not be able to find it quickly, it's so small.

  1. A photographer friend (who prefers to use a telephoto lens on his camera) points out how shallow a fieldscope's depth of field is. He thinks I did pretty well getting a focused photo, and suggests that the use of a magnifier loupe (held to the fieldscope's eyepiece) might facilitate the sharpest possible focus.
  2. A vertical panorama shot is also possible, for a tall building or cliff, for example.
