can somebody confirm that what im looking at are craters on the moon? This was taken during the 2024 eclipse from illinois with my S24 ultra iso250 115mm -2.0ev F3.4 speed 1/10000. thanks

  • $\begingroup$ Beautiful photo! I can't confirm it myself but it certainly looks that way. Since the Moon is not a polished sphere but instgead quite rough, certainly some areas very close to the limb will still be at least very obliquely illuminated so it's geometrically possible. For confirmation all that's needed is for someone to run a simulator like Wtellarium to first see the exact topography near the lunar limb at that time, and then (if the software supports this) use realistic solar illumination to see if you can reproduce the same pattern. $\endgroup$

    $\begingroup$ those are likely either lens/filter issues, or poor seeing conditions, exaggerated by the overexposure. They are not craters $\endgroup$

  • $\begingroup$ @Topcode what factor so completely rules out any possibility that they could be reflections from topography? $\endgroup$

    $\begingroup$ @uhoh Well, there are a few. For one, the moons illumination was roughly the same size as would be depicted in the image, a day after the eclipse, there is zero possibility that level of illumination could occur during the eclipse. And even if it did, the moon has a surface brightness about 400000 times less than the sun. there is most likely not a lens in existence, which can capture that level of difference directly adjacent, with no bloom. $\endgroup$

    $\begingroup$ The best evidence they are not craters is that other people's photos don't show them. $\endgroup$

Eclipse april 8 1:57 p.m. from springfield,Ill

OK So yeah from this pic, exact time and date, I'm certainly not seeing the craters that I was hoping to see as in my pic. Was cool to think so anyway. Thank everyone for the help!

    $\begingroup$ Can you please consolidate your answers into one? They make sense combined, but dont answer the question alone $\endgroup$
