ISO 100; 1/100th sec.; prime focus.
Attempts to do eyepiece projection reminded me that I need to use the Scheiner mask to get a sharp focus, which was not worth the effort in such cold weather.
25mm eyepiece projection; ISO 100; 1/4 second. As the magnification increases, of course, light available drops and longer exposures are required.
12.5mm eyepiece projection; ISO 100; 1/6 second.
Ever considered using a glove with the tips of the fingers cut off? You can buy such gloves commercially made or make your own. Get a sweatshirt with a built in pocket over the stomach area (like a woman's muffler?? In olden times). Keep a hand warmer in there too. You sometimes see quarterbacks using this type of clothing when playing in extreme weather.
ReplyDeleteI also recommend the heated vests. (Motorcycle riders use them, but so do friends who work outdoors.) They aren't cheap, but a charge will keep the vest warm for about 8 hours on low.
