    At least it's something

    We had heavy cloud cover form over us about 1 1/2 hours before the eclipse but finally they opened just long enough to see this and another glimpse a few minutes earlier. It was all razor sharp looking through the eyepiece in my solar telescope but I just can't get the camera to focus or capture it as well. My scope sees sunlight in the H-alpha range which is deep red. I wish I'd taken more practice shots before today as I didn't realize how differently the camera saw it than the eyepiece did but the surface detail is amazing with a regular 20mm eyepiece. I shot quite a few different shutter speeds and played with different ISO, then just set that to auto. Note the lens opening shows f/0 since the camera body was thinking "what the heck is this thing?".

    RE Survey Sections

    Positioning for guns and missiles using MX1502 satellite doppler equipment.

    From DARPA website: ARPA launched the first satellite in what would become the world's first global satellite navigation system. Known as Transit, the system provided accurate, all-weather navigation to both military and commercial vessels, including most importantly the Navy’s ballistic missile submarine force. Transit, whose concept and technology were developed by Johns Hopkins University Applied Physics Laboratory, established the basis for wide acceptance of satellite navigation systems. The system's surveying capabilities, generally allowing for accuracy in the tens of meters range, contributed to an improvement of nearly two orders of magnitude in the accuracy of maps of the Earth's land areas. ARPA started the Transit program in 1958 and transitioned the technology to the Navy in the mid-1960s. By 1968, a fully operational constellation of 36 satellites was in place. Transit operated for 28 years until 1996, when the Defense Department replaced it with the current Global Positioning System.
