OK., I concede that maybe the non-parallel shadow property is an illusion resulting from the pixel aliasing in the upper parts of the image. If you enlarge the image, the shadows become aliased after around the second, structural rail. This aliasing might make it appear that the shadows are not...

That might rule out AI. But Photoshop (or similar) and ray tracing have been around for decades. It may be a real bridge, but with the shadows in the image manipulated in a Photoshop (or Photoshop-like) program, such that the actual shadows were replaced (via "Clone Stamp" and "Free Transform"...

I'm guessing the shaded side is to reduce the visibility of one of the doubles, to help compensate for the Jameson.

I suspect the image isn't real. As in, I think it's most likely photoshopped or ray traced or maybe AI generated. Here's my logic, in two parts: (1) The vertical posts are vertically parallel. When illuminated by a very distant light source (like the sun) they should produce parallel shadows...

Yep. There's truth to this. I've known about this for about a month now, being as I try to keep up on such things since I build my own computers. It's worse than causing "crashes," though: it places the CPU (and indirectly the associated cooling systems) at a too aggressive operating point that...

Does the app use GPS to track her route? If so, I would expect it would be pretty accurate (i.e., the 0.698 m/step would have been calculated based on the GPS measured length of the route*, and not the other way around). * Edit: and the number of steps, which can be recorded and counted based...

That's an important question worthy of discussion. The answer isn't simple. If I had to give a short answer it's this: the color saturation that I used in this image is higher than what would normally be used in a terrestrial photograph. And the color saturation that I used in my photo is...

I've got more data! :smile: Here's M100 (a.k.a., NGC 4321, "The Blowdryer Galaxy," "The Mirror Galaxy") with about 37 hours of data and a lot more care with post-processing. (It's the same target as before, just with more data and more care.) Not only did I gather more L, R, G, B data, but I...

The Blowdryer Galaxy (a.k.a., M100, NGC 4321, Mirror Galaxy), imaged from my back patio, March-April 2024. The galaxy is about 56 million light-years away and can be found in the constellation Coma Berenices. Figure 1. M100. I understand the "Mirror Galaxy," nickname, due to its symmetry I...

Tell me about it. It's been this way for awhile now. (We might have a clear night next week though. Maybe. But the comet will be too close to the horizon for my setup though.) Regarding 12P/Pons-Brooks (the "Devil's Comet"), Over a month ago I did attempt to plan out (using Stellarium) a good...

There's definitely some truth there. The first half of my life I spent in America's heartland. I've been in both situations more than I can count. While I wouldn't necessarily recommend the second, cracking open a beer and sitting on the front steps looking around the sky for wall clouds is a thing.

Forgive me, but I was sort of pulled into this thread by accident when my post from a different thread got moved here. So when I started commenting it was without the context of the whole first part of this thread. But now I do have a question. I'm led to believe that the bosonic creation and...

Yes, of course. They only measure discrete detection events. The same is true of the pixel elements in the sensor of my digital camera.

Here's a few. Wavefront sensing with prisms for astronomical imaging with adaptive optics "A scenario where a read out noise of 5 electrons is also evaluated and the 3-sided prism WFS is found to have a Strehl ratio 12% higher than that of the pyramid WFS with a photon flux of 5...

Although I was about 10 years old, that was my reaction when I first got glasses.
