 In a limited sense, you can just plop the Seestar down, turn it on, and start capturing images—limited in the sense that it will only really work using Stargazing (DSO) mode.  In a limited sense, you can just plop the Seestar down, turn it on, and start capturing images—limited in the sense that it will only really work using Stargazing (DSO) mode. 
  
-The Seestar knows where it is (your mobile device told it), it knows what time it is (ditto), it has a built in compass so it knows where it’s pointed((Initially, and after bouncing around while traveling, you should recalibrate the compass. Tap the picture of the Seestar on the Home Screen or Me button on the right end of tghe bottom menu, then tap the Advanced Feature label, then tap Compass Calibration. Watch the graphic, turn around three times, click your heels twice, and yell “Galileo” when it’s finished. Only takes a few seconds.)), and it will figure out where the horizon is with Horizontal Calibration, no finicky leveling required. If you tell it you want to image, say, the Whirlpool Nebula (M51), the Seestar will slew to where it thinks it should be, take a picture, perform some magic using plate solving so it knows where it actually is looking, do some quick spherical trigonometry calculations to compute where it needs to go, and then repoints the scope. It will keep doing that until M51 is centered in the camera’s view.+The Seestar knows where it is (your mobile device told it), it knows what time it is (ditto), it has a built in compass so it knows where it’s pointed((Initially, and after bouncing around while traveling, you should recalibrate the compass.

 In another case of YMMV, some Seestar owners will insist you have to carefully level the telescope and recalibrate the compass every session. If you want to find the Sun or Moon it does have to be level((You can help the scope find the Sun by slewing it in azimuth until the Sun shines through the crack between the telescope arm and the main body. That crack is also a handy aiming sight when you’re trying to shoot the Moon or something in Scenery Mode. Don’t look through the crack at the Sun!)).  But to capture images of DSOs (deep sky objects), plate solving will do the job. When you’re hunting DSOs, it automatically does a horizontal calibration using a three star plate solve to compensate if your leveling is off, and then it goes to your target.  In another case of YMMV, some Seestar owners will insist you have to carefully level the telescope and recalibrate the compass every session.
