I was out again checking set up time and doing another test.- Ten minutes to get all set up.
The rest of the test consisted of checking camera automation plan and the sun drift caused by using a fixed mount.
Automation plan -
Exposure 1/2000 sec, ISO 200
Exposure 1/200 sec, ISO 200
Exposure 1/20 sec, ISO 200
Exposure 1/2 sec, ISO 200
I plan to set this sequence do a continuous loop starting 2 minutes prior to totality until 2 minutes after totality. Total time of 5 or 6 minutes depending on our exact location.
- The Explore Scientific Twilight I mount is very sturdy and able to preform fine adjustments.
- Using a fixed tripod with a 400 mm focal length telescope limits the exposure to 1/2 second. I tried a 1 second exposure and the sun started to look oblong.
- The 4 exposure sequence takes approximately 16 seconds using Backyard EOS saving to the camera.
- The sun is really bright! No kidding Sherlock. Notice the first 3 exposures compared to the 1/2 second exposure. I did not change the size or zoom in, brightness is just that it masks the surface. That's why you need solar filters to look at the sun.
- I may miss Bailey's Beads or the diamond effect as the sun enters totality due to the amount of time it takes for the exposure sequence but I am very familiar with this procedure and it is automated so I can enjoy seeing the eclipse (HOPING NO CLOUDS GET IN THE WAY)!
