Looks pretty Good Darren. I like the recycled use of the old shed, well done. The running track looks pretty good too. I do have some small suggestions for you which will help later.

1. to prevent water entering the observatory at ground level you should use a bead of silicone around the junction between the walls and the concrete. I would use Selleys All Clear.

2. Consider putting gutters on the shed roof. It will make a huge difference to how the water is directed away from the observatory. Any water entering in the floor level will lead to mould.

3. If you have not done so already, consider cutting an isolated pier support for your pier. If you bolted the pier onto the concrete you will get vibrations even just walking around outside. A concrete saw and digging a hole for a pier support is the best solution. Forgive me if you have already addressed this. I don't know what you did with the pier.

4. Pay some thought to vermin. I have sealed my observatory pretty well now after several instances of vermin entering and setting up home. Birds can be a pain as well as mice. Spiders will always find a way in, but thankfully baygon makes a huge difference. I once took the cover off the scope and a mouse lept at me. The killer mouse was later trapped and delivered. It had peed all over the scope and mount. Mice can be particularly persistent and cause lots of damage. They love to chew on things.

Well done on the job and I hope you get years of enjoyment from the observatory.
