I'm in the process of working out what backyard observatory I'd like to set up as I've reached the stage that I'm like something more permanent that I can use more quickly during fickle weather conditions like we've got now.

I'm currently thinking of a roll off shed design, mostly because it's likely to be significantly cheaper than a dome.

I am concerned though about what I need to consider for this given Brisbane conditions - hot and very humid - plus (the possibility of) tropical storms/winds.

Will I need to insulate the walls/roof to reduce internal heat during the day? If I do that, am I likely to be affected by the insulation at night?

What's the best way to handle the humidity?

Any tips or thoughts appreciated. I'd especially like to hear from people in a similar environment to myself what challenges they've encountered / overcome. Thanks.
