NGC253 also known as the Silver Coin, Silver Dollar Galaxy is an intermediate spiral galaxy in the constellation Sculptor.
My first time using the new harmonic mount to shoot after a few times testing.
The guide is better and better but still has trouble when ASI Autorun finished in the morning.
The mount didn’t goto the right home position instead of goto 180 degree.
