With these hi-res images I'm always curious which of the stars actually belong to the galaxy and which ones are "noise", i.e., stars that are from our own galaxy "blurring" the view.
I think filtering out "local" stars should be very doable given ML/CV progress.
- Moru 8y agoThere is probably some easier way of doing this but if your favourite tool is a hammer, everything starts looking like nails I'm sure :-)
- NickNameNick 8y agoWith images taken 6 months apart, spanning earths orbit of the sun, you might be able to detect some parallax motion of the nearest stars.
