I broke out the gear from the 2024 eclipse just to see if I remembered how to set it up. I did.

Our eclipse adventure on April 8th resulted in around 750 images, of which 650 to 700 are of the sun/moon/eclipse. The images in totality number just under a hundred from one camera. I’ve been slowly going through the images, some of which were shot in bursts.
This wasn’t our first rodeo. Still, there’s a lot to cram into four minutes and a lot which can go wrong. I estimate I only got 20% of my planned shots.
This may be the one.

Mother Nature giveth and Mother Nature taketh away.
On Monday, April 8, 2024 there will be a total solar eclipse across North America from Mexico, across Texas, Oklahoma, Arkansas, Missouri, through to Canada.
At this point there’s good news and bad news. The bad news is that the weather forecasts are predicting cloud cover and rain for a significant radius from us. The good news is that weather forecasts this far out aren’t very accurate. We’re crossing our fingers.
Meanwhile, we practice. The Sun this afternoon:

Peace and calm. From a distance.
NASA:
As of June 2020, NASA’s Solar Dynamics Observatory — SDO — has now been watching the Sun non-stop for over a full decade. From its orbit in space around the Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system.
With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer — the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled “Solar Observer,” was composed by musician Lars Leonhard [….].
While SDO has kept an unblinking eye pointed towards the Sun, there have been a few moments it missed. The dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. A longer blackout in 2016 was caused by a temporary issue with the AIA instrument that was successfully resolved after a week. The images where the Sun is off-center were observed when SDO was calibrating its instruments…
