A lot of modern smartphones support long (~30s) exposures, with compensation for motion during the exposure. Under the right conditions, they can take some very nice night sky photos -- and I suspect they'd do very well on the end of a telescope, too.
- dekhn 4y agoin 30s, the stars have moved. Do the phones somehow derotate?
- duskwuff 4y agoI believe so. The phone can compensate for its own physical motion during an exposure (e.g. when being held in shaky hands); proper motion should be no different. If anything, it's easier, because it's so smooth. :)
