Completed Pier, Now for the observatory

[mtodman]

After many a hot & hard day's work, I have finally finished my backyard Pier & observing platform for my LX200 (see link)
http://www.astroromp.com/astronomy/permanent_pier.htm

I am currently using a Telegizmos 365 telescope cover to keep things dry & hopefully cool(ish) but my plan is to construct something more permanently to cover the pier / scope. I was thinking that a walk in box about 1 - 1.5M square that is tall enough to cover the scope would do the trick. I'd hinge the top 1 - 2 feet so that it could flip open.

I've been troweling the web for examples of a small obs / scope cover similar to this but haven't been able to find anything. Does anyone know of such a small obs being constructed elsewhere? Does anyone see any major issues with such an approach (ie, heat buildup, etc)?

Cheers,
Matt

In your position, I'd build a small shed/obs' that would cover the whole slab that you have there. That's the only way you'll get it to be a walk-in arrangement, that I can see. Other than that, you could build a clamshell hinged box big enough to cover the scope and leave a bit of room surrounding the scope. It'd have to be waterproof and able to withstand a storm and the occasional southerly buster. But then you'd have heat issues and that would entail installing extractor fans to keep everything cool.

just a idea for your shed, have you looked into the garden sheads, you might be able to modify one for what you need. ive looked at them because they are a good price! you can get one for 500 - 1000 with all the bits you need.

Top job indeed Matt, sounds just about the same as i did mine, even down to the aulminium plates, this should see out for many years to come.

Nice and solid.

Nice Garden, Here in Melbourne mine has just frizzled away.
Looks like a great start.

I actually saw a good idea on the web a while ago, I will let you know if I can find the link but someone had converted a plastic water tank into an obs. The roof hinged of the back and a door was on the blind side. It also had some re-enforcing for the wind added internally. It had the obvious advantage of security - who would think a common backyard tank would contain something so expensive!

With water is getting expensive down here now, and in a year or so may be worth more than a LX series!

Thanks for the creative suggestions.
Unfortunately, due to spousal restrictions I am limited to a "small" obs (you wouldn't believe what I had to do just to get signoff for the pier & paved area). Assuming that I'll be restricted to an area of ~1M x 1.5M for the base of the structure, is anyone aware of a cooling / ventilation system that would work?
We're getting daily temps hitting 40 degrees c at the moment & I hate yo think what that would get to in a small obs without some form of cooling.
Is anyone aware of what a "safe" non operating temperature would be for a setup such as mine? I assume that too high a temp may damage the OTA / electronics.

you would be very serprized by what Colour bond tin will do for cooling, recently Roger Groom (rogerg) posted a thread about this, and that the inside of his obs was 3 - 4 deg cooler than ambient. I think its something to do with Infrared cooling theres a whole science behind it. but keeping your obs all closed up has some advantage! plus you seal it off from the dust!
