There is no wide-angle lens, only a SLR camera. Can you shoot the star track?

Yes, you can. You need the following tools.

SLR camera

stitch

Cable releaser with self-locking function

tripod

Because it takes 30 minutes or more exposure time to shoot the orbit of a star, it is impossible to shake off the camera in your hand at this time, and the longest exposure time of a general camera is only 30 seconds, so you need to use a cable.

First find the shooting point, then set up the tripod, install the camera, adjust the angle, and then connect cable release to set the parameters (thousands of seconds). Then press the shutter button on the shutter line and start shooting.

Be careful not to move the camera when shooting, otherwise the photo will be blurred.
