    Hi all!
    I'm kinda new to photography (I just started, I'm not good), and I'd like to take some shots to the stars as much as it's possible, the goal is to get a star trails(ish) shot.
    This is the first attempt, the plan was to keep the OPO out of the window for about 2 hours taking pictures every 30 secs, with those 30 seconds completely covered by the exposure time.
    Basically every 30 seconds a new picture was taken (and stored, of course), and that picture was taken throughout those 30 seconds.
    Unfortunately I needed to use the phone so I had to stop the process, but here's the result of like 30 shots (out of 200). Any suggestions on how to avoid those gaps between the different shots of the stars? (It should appear as a continuos line).

    I've used Camera FV-5 to take the pictures. It's got a bult-in timer and intevalometer.
    Also I was wondering if any of you knows of a way to turn of the screen during the picture taking?

    Well the maximum time is only 64 seconds shutter time, and i made quite a good picture with 20s shutter time in total darkness (italy)

    I'm italian as well, but here in Turin nights aren't really dark yet, therefore using a longer exposure (given same ISO and of course aprture) would result in an extremely overexposed shot.

    Yes that is true, go to a remote spot somewhere maybe? Far away from cities etc..

    Usually people uses ultra long exposure to capture the moment is stars in the sky hence you see the circular light trails. Not sure how long can u expose on the oneplus though, never tried.

    Oh and I think u might want to find somewhere that is away from light pollution. Means total darkness like @Peanutbrain said.

    Nonetheless great picture still. I doubt I could make it. Esp the time lapse vids

    Nope. It's not a single shot taken with extra-long exposure, otherwise you wouldn't be able to see the "trails", but instead you would more likely see something like a sky. A normal sky.
    I've managed to understand and I'm currently checking my third attempt, see you later!

    And thanks.

    You're doing very well. To get rid of separate dots, one must either synthetically merge the dots in post, OR use a time-lapse that takes more frequent shots.

    tried with ISO 800 and 20 sec exposure, and set the interval up to 20 sec and 1.20 hour capture time..after stacking them I didn't get smooth lines..there are gaps which are noticeable :(
