Incredible atmospheric optics this morning
Large & Small Magellan Clouds above the VLT while using adaptive optics - the "guide stars" created by the lasers help compensate for atmospheric turbulence so the observation is as sharp as possible (Juan Carlos Munoz)
An extremely curiferous picture ofskyline of Chicago from nearly 50 mile away. Clearly it's peeking-up from beyond the horizon - ie it's _just totally not_ sitting there on a flat plane - but doing so to such degree as could only be brought-about by extraΓΆrdinary atmospheric optics. np.reddit.com/r/interestiβ¦
Interesting DSP application: Modelling the propagation of laser beam in the presence of atmospheric turbulence and through a Cassegrain telescope for evaluation of an adaptive optics test setup. v.redd.it/r85kpkvtsci61
What is the best sub for those interested in atmospheric optics?
Hi, I'm interested in Free Space Optics (/r/lasercom), and wonder if there's a good hangout for those interested in atmospheric physics as it pertains to electromagnetic transmission?

This was back in 2016 before I knew anything about atmospheric optics. My house was blocking the sun so I didnβt see any parhelions or halos. Can someone take this photo through image processing to see if their was a 46 halo or supralateral arc hidden there somewhere?

ELI5: How do Adaptive Optics know how to correct for atmospheric distortion and give us Hubble-quality images from a telescope on the ground?
The atmosphere is always changing (why stars flicker), so how can AO correct for that in realtime?
Earlier today someone asked what this phenomenon was on the atmospheric optics thread. I had just seen this 45 minutes before reading their post. A pileus cloud with iridescence driving back to Nilaveli from Trinco this eve.

"Crepuscular rays (more commonly known as sunbeams, sun rays, god rays), in atmospheric optics, are rays of sunlight that appear to radiate from the point in the sky where the sun is located." No shortage of these up here in the redwoods during the winter :)
