I found with these Dob's that if i was set up on unstable ground or grass, the mount was wobbly.
So I went to the local garden supply shop and brought a 600mm round 2" thick concreate paver.
I have put that in the ground and leveled it. The scope is a lot better on the paver, a lot more stable
Mind you i can't take the paver when I'm observing in other locations.
I'm not that strong
