I would use a better tripod, plus some concrete blocks under it (or make a proper plinth) or it will fall over.
As above - as it is now, that dish will fall over in any sort of "wind" as the tripod legs are too short (and likely to bend /distort), and it will be very difficult to accurately align anyway because the whole setup will "rock" very easily as you try to do that.
Edited: picture below shows my 1.25m Gibertini at the seller's house before I bought it: the NPGM is a rectangular unit (in 3 separate sections, bolted together) and was weighed down with 4x concrete slabs.
It was also located in a very sheltered spot behind the house and between two closely adjacent fences - so not likely to get blown over.
PS: Pity you are not in the UK as you
(or anyone else??) could have that NPGM "very cheaply" as the Gibby is now on a mast!)
