That's a really good point. I think there's a high chance that the photos were taken from quite different locations because Hubble orbits the earth at 570km, whereas JWST is actually at the L2 Lagrangian point, which is about 1.5 million km away from Earth.

Thanks for the comments! It does look like some stars may be exhibiting stellar drift, I've isolated an example here: https://academo.org/demos/james-webb-vs-hubble-telescope-com... This is from the middle-right side of the deep field. If you look slightly below the two central galaxies, there is what looks to be a foreground star (I say that due to its brightness and the fact it has a starburst effect) and between the two frames, there seems to be a noticeable shift in position that doesn't occur with other objects.

Thanks! My plan is to open source the whole site in the near future, but I'm trying to do a bit of a tidy-up and refactor before then. In the meantime, your very welcome to view the source code for any of the demos, like this file used for the oscilloscope: https://academo.org/demos/virtual-oscilloscope/demo.js

OP here, thanks for the feedback! And that's a really interesting tip about the stereo line-in. That's given me an idea about maybe trying to display some Lissajous figures on the oscilloscope.

Thanks! Listening to the recording, I'm reasonably sure I can distinguish the two different frequencies, but there's no denying they sound very similar. They're so close there's less than a semitone between them.

Ok, no problem, I've uploaded both audio files to my SoundCloud account (https://soundcloud.com/outputchannel) and you can download them by clicking the download button beneath the waveform display.
