- postalrat 5y agoMaybe two telescopes and a bit of math to use the difference in distance to the satellites vs the asteroids?
- s1artibartfast 5y agoLong exposures can still have a duration censored. This is digital photography, not chemical. If you expose for 1 million seconds, you can edit out 60 seconds where a satellite passes. That data is forever gone, but you still get the rest of the data from that pixel time.
- mhh__ 5y agoGiven that the earth rotates every 1.5 thousand or so minutes something tells me 1 million may not be representative...
- s1artibartfast 5y agoSure, I was being extreme, but multi day or week surveys exits. In fact, they already have to do a lot of filtering to remove transient artifacts
- nieve 5y agoYou're assuming there's only one satellite to worry about per exposure.
