Thanks a lot for sharing your experience with us.
replyI worked adjacent to this area from the 1990s-2010s when the topic is solar physics is definitely why this forum is one of the last "places" of the internet.
Sure thing.
replyRemote sensing of the Sun is different from anything else, because you have so many photons. The idea of binning it down so fine (20x20km, 740Hz, a single nm of spectrum around a band center) is unheard of for any other target.

replySilly question but how does a 4m aperture focused onto a smaller area not concentrate the heat and melt the instruments?
replyIt's highly filtered, you are only getting a small slice of all of the wavelengths. Only a tiny fraction of all that energy hits the photo collector. I believe the collector is also actively cooled, but I might be wrong there.
reply> The subject has been very qualitative
replyWhat does this mean?
"Qualitative" means that the field had good conceptual theories, but didn't have sufficient observational and computational resolution to determine the detailed numerical values
replyWell put. And to round out the nomenclature for those that are curious, the corollary here is that it can now become much more quantitative.
replyquality vs quantity
