How long will it take for Nubian calf 3 nebula mode to capture the stars?

Hello, Nubia is known as the SLR camera in mobile phones. Nubia initially added functions unique to SLR cameras, such as electronic aperture, slow door, manual white balance, manual focusing, etc., using electronic aperture to achieve long exposure time of several hours, using manual white balance to show the blue night sky, and using manual price adjustment to aim at the stars in the dark night sky. The optimization of these softwares has created a Nubian mobile phone that can shoot stars.

Shooting the orbit of the nebula needs to be in the pure dark sky without light pollution. The shooting track needs a tripod to fix the position of the mobile phone, and it takes at least 2 minutes to become a piece. When shooting the nebula mode, you need to use the equatorial camera (SLR camera is also necessary) to offset the displacement effect caused by the earth's rotation (if you don't use the equatorial camera, the photos you take will still be the star orbit map).

Thank you for your concern and support for Nubian products. I wish you a happy life. Thank you.
