My then ror observatory was broken into around 2001 and my 12inch GPS stolen, it was obviously a targeted thing, bolt cutters were used to gain entry while we were on holiday. Thankfully it was all insured and had a quick settlement for new for old policy that I had. I've since moved years ago from there and now have a pulsar dome in my current situation. Last year our neighbour lit up there's and our back fence, conifer tree's. It was a huge blaze from their bbq, fire engine's the lot. We were out there hosepipe on the sheds and fibreglass observatory, they were steaming with the heat. The plus side is I now have a good easterly view where huge conifers used to be. Still glad I'm insured though. My dome is also alarmed.
Moral of the story is get insurance. It's sometimes covered under outbuildings and contents but check the values as you might need to up that.
