Welcome to my astronomy blog, I dedicate myself to the simplest form of amateur astronomy which requires only portable equipment. I have two small refractors, two small binoculars, one small GOTO mount and another small equatorial mount, and a small H-alpha solar filter. Originally from a city where the people were proud of their light pollution, that is Hong Kong where I loved. Relocated to the UK since 2021.

The iOptron SmartStar-G on Gitzo G106
On going to the Post Office to send my DMK 31AF03 to the US, I found that there is a very well stocked screw shop near my home. I bought a long M8 screw together with a few washers, and the iOptron is mounted to my Gitzo G106 successfully.
I placed my Ranger there, and it's a very stable setup. On focusing, the vibration would damp out at around 5 seconds, not bad. Slewing around is smooth and accurate, a good sign of excellent backlash compensation. It's cloudy outside so I couldn't really test it. I turned on the tracking and insert a high power eyepiece (185x), slew the scope to a terrestial target, watch it track. Tracking is pretty stable with some very minor vibration, I don't know whether it's induced by my eyes or by the tracking action itself. Focusing is easy since I've a NGF-CM, so focusing induce zero vibration to the setup.
I've yet to try it on solar imaging, but it looks promising right now.
