Click For Summary
To calculate the intensity of light in different sections of a 2D Airy disk from a point source, one must utilize Bessel functions. Online calculators for Bessel functions are available and can assist in these calculations. The discussion highlights the importance of understanding the mathematical details provided in resources like Wikipedia. Users are encouraged to search for Bessel function calculators to facilitate their calculations. This approach is essential for accurately determining light intensity in the Airy disk pattern.

You need to be able to calculate values of Bessel functions. I've seen online Bessel function calculators... try a Google search for them.

Thanks Jtbell. I actually found that about an hour or so after I posted lol.
I'll look up that Bessel Function calculator, thanks for suggesting it.
 

Thread 'Looking for info about the Sombrero Galaxy'

Hi, I saw someone with an avatar on a different forum that turns out to be the sombrero galaxy. AI says, too distant to know much about, aside from billions of starts, potentially tons of planets, and a supermassive black hole in the center. I find that setup fascinating, despite knowing close to nothing about the universe. So I ask: could anyone point me in the direction of, or provide information about this galaxy? I do not trust AI beyond general information, and I like to go pretty...
