Description

It's a long time since I prepared for this.I bought Skywatcher 10'' newt、GEM45 mount in Aug. 2021,and kept waiting for the carbon fiber tube for many months. 
The total weight of newt and other equipments on it(camera,OAG,ZWO EAF,etc)was about 14kg,but GEM45 can handle it stably. I got 0.5-0.7'' RMS error usually,and 1.0-1.2'' when there was a bit wind.

This is also the first time for me to use a Mono camera,it's really a challenge to deal with so many channels.
