this is unbelievably amazing, how does 12 hours of exposure not having any star trail? sorry for being a newbie.

Sid, in deep space imaging we use Computerized German Equatorial Mounts (CGEM) to track objects across the night sky. It has two axes: Right Ascension and Declination. This enables a photographer to shoot extremely long exposures and also eliminates field rotation associated with Alt/Az mounts. Hope this helped.

thank you for the explanation.
