My first thought looking at it was how many spiders would be living in it within a week?
Too open. In the last year with those hot days with high winds whipping up inland red dust I was amazed at how much red dust got on everything.
It needs to be covered properly to be weather tight at least against dust.
The Fornax Lightrack 11 is a nice nightscape tracker that uses a friction drive.
It has very low PE but with trackers its more about achieving a decent polar alignment than it is PE unless you start imaging at 300mm.
