Infrared New Hampshire
I brought my small telescope with me (as I always do) on vacation to New Hampshire earlier this month. Alas, very little rainfree time to point it overhead this year... but I did bring it down to the boathouse to experiment with a little infrared photography. The small filter I use is centered at 780nm in the near IR. The eye is almost completely insensitive at this wavelength, but digital cameras for astronomy (I use a scientific webcam for this) which have no IR blocking filter are quite sensitive to this light. These images are made using single frames from short movies, shot at a focal length of 480mm across the lake. There is only one hat visible. Hope you enjoy them anyway!
