They survive OK, but the light from the scope takes its toll.  It is an overhead LED, but light is still light, and black is still black and absorbs light and heats up.  With only 2 degrees F leeway, it is not enough.  Will have to hope for more snow when it gets colder. Here are are a few first attempts.  I had to change background materials as the one I bought was too fibery and you could hardly see the flakes for the fibers.  These are just black matte board, all I could find that was handy.
