It is on the mount.. 14kg total (10kg concrete, 4kg metal) is enough to balance my 10" Newt.
So, I need to add 6~7kg of concrete to the existing counterweight, that will be 2/3 of the cake box mould (just to cover the reinforcement, visible on the pics). The counterweight will then have to be 6-10cm closer to the OTA than it is now
If I need any more weight on the OTA in the future, I just have to move the counterweight a bit further away from the tube.
The total load on the mount will be ~35kg... a bit heavy but probably within the carrying capacity of the EQ6.
