Great shot....must have a good sturdy tripod or a low resting pulse, did you mirror up or not ?
I have a Manfrotto 190CX tripod... but the main improvement I found was the DIY bracket I put together to help brace the lens/body and move the pivot point to get the setup balanced and more stable..
I normally shoot tethered either off my Android tablet with DSLR Controller or my Mac Air so mirror is up anyway...
The setup I use...
...biggest issue is how quick the moon moves at what is effectively just over 1200mm focal length...
Planning on getting a tracking mount this year and try some deep sky objects as well..
There's a guy on a photography forum I am on, uses a tracker mount and a Schmidt-Cassegrain telescope... his results are astounding... one day I might get that involved but its a fair trek to a dark site for me so won't happen just yet.
Have managed to get a decent milky way shot though considering the light pollution in the area I took it
