Thank you!! It is crazy standing next to this and thinking "wow this is the biggest thing I've ever seen" meanwhile there's a 10m telescope on the next mountain over!

Merci beaucoup!!

This particular night I was observing several different metal-poor stars in the disk of our Galaxy, looking for heavy elements (like Uranium and Thorium)
