Processing total solar eclipse images

🏗️ This page is a work in progress. 🏗️

This blog post will eventually include a summary of how I processed my images of the April 2024 total solar eclipse (TSE). My goal is to reproduce–at least in part–the methods of Miroslav Druckmüller, Nicolas Lefaudeux, and others using Druckmüller’s pubished methodology… but this is much easier said than done! 😅 For now, this post will simply contain a list resources I found useful.

I imagine the final process will be comprised of the following steps: (these will likely become links to …


Taking images of a total solar eclipse

Taking images of a total solar eclipse can be challenging. Some say the eclipsed Sun is the most difficult astrophotography target.

For the rest of this post, I’ll be assuming you’re using a modern DSLR/mirrorless camera, but the same advice probably applies for dedicated astrophotography cameras and maybe even film cameras. Some hardcore eclipse photographers take photos with multiple different cameras and composite them together, but that’s outside the scope of this post.

(This post is a little bit ~stream of consciousness~, sorry. There are lots of other resources about …


FINESST Stats

NASA generally selects about 130-150 FINESST proposals each year or about 15% of total submissions. The exact selection rate varies from year to year and by division, but Astrophysics typically has the lowest selection rate and Heliophysics the highest. The overall selection rate across all divisions has been fairly stable in recent years.

The 2019 solicitation saw submissions drop by ~20% due to the COVID pandemic, but the volume of submissions has since returned to pre-pandemic levels. During this time, the number of selected proposals also increased, such that the overall selection rate has …


FINESST Tips & Tricks

The FINESST1 program is one of the largest funding programs for US-based graduate students in Earth and Space Sciences. Unlike many other large funding programs, FINESST accepts applications from international students. It encourages submissions from graduate students at any stage in their studies, from newly-admitted to all-but-dissertation. New FINESST proposals are typically due in mid-February, and selections are announced in the summer. The most recent FINESST solictiation can be found here.
