Any amatuer (or professional) astrophotographers capture the annular solar eclipse today?
I was only able to see ~70% coverage in my area, and was hoping to see some posts here on Tildes about the eclipse. I'd love to see anyone's work they managed to capture today.

This random late-night thought that hopefully someone can quickly point me to (my Google-fu is weak tonight). I'd like to see some pictures of space from the ISS that don't include Earth. I live in an area that is heavily light polluted so my nightsky view is terrible and I've seen amazing images from other places on Earth that look stunning - I figured a view from the ISS would be even more amazing.
Some of the ones I've quickly found on google appear to be photoshopped - as I'll find the same scene with only a few stars, another seemingly showing the entire Milky Way and then another plain black highlighting the earth.
Many Thanks!

Quasar hunting in amateur astrophotography

I'm not sure how big the astrophotography community, if any, is on ~tildes but I'd figure I'd open a topic up and see! Astrophotography is one of my hobbies, and it was brought to my attention (see link for two quasars near the M3 globular cluster) that it's actually pretty easy to photograph quasars. The same are visible in my attempt at photographing M3. Anyway, my question here is does anybody know of any particular interesting or distant quasars to photograph? I assume most will just be "dots" but it still sounds like fun since they're among the most distant objects you can see. I assume most quasars would be broad spectrum, so no filters are really needed, but I'm also curious if there's any bright yet redshifted objects you'd need infrared to capture.
My setup is an Astro-Tech AT80EDT 80mm Refractor f/6. I just got the f/0.8 reducer which I'm excited to take for a spin. It's a chonky piece of glass. My camera is a ZWO ASI585MC which does decent enough for deep sky.
Edit: To add, using something like http://simbad.u-strasbg.fr/simbad/ is great for finding interesting objects once I've already taken a photo, but it's less helpful to plan my shots.
