Sky Shed Ransu

[Gina]

And thank you for posting all your interesting photos and explanation. We have really enjoyed your thread

[spaceboy]

Looks lovely, but when I see the inside I keep thinking "sauna"

LOL I was thinking the same. As much as I like astronomy I like saunas more. Just keep on using your scope on it's tripod and turn the obsy into a sauna

I think you have done a very professional job of this build Rauno and you should be proud of your accomplishment.

On another note do you see much of auroras over your way?

Very impressive build Ransu. I'm sure it will give you lots of pleasure when the dark nights return.

Don't joke about sauna's- my wife wants a hot tub & sauna IN my warmroom. I think think she may have got he wrong end of the stick when called it a 'warmroom'. Still- it's not a totally insane idea......stargazing from a hot tub.

Auroras have been rare last years, and i haven't seen good one at long time. Maybe raising solar activity will bring them back. I think ihave seen my best auroras at early -80:s when i was teenager and beginning this hobby.

Very enjoyable project, looks great Ransu. Looking forward to seeing some results from Finnish observatory now that its almost "Finnished" lol

Laser has a good idea. I think a Hot tub build is next on the to do list now Ransu. You can then sit back in the tub and look out for auroras and meteor showers

[Essex Stargazer]

A very professional build

The end result looks very stylish

I hope you enjoy many happy hours in your new observatory

Thanks for showing us

[Ransu]

Todays progress:

Outside white painting work done now. I have to say i dont like to do painting.

Inside floor done with Osmo color natural based wood wax. Colour is Cherry.

I think i will continue inside walls with Osmocolor too, but different colour.. maybe blue could be ok

So.. bye bye Sauna look, sorry for that:D

Outside 25.6

And inside floor:

Looking great Rauno!!

I'm sure it will make a better obsy than a sauna in the end anyway

Are you boarding the Walls inside or leaving them as they are ?

BTW you have a beautiful house.

[Gina]

Looks lovely

[Ransu]

Thanks spaceboy, house has been build 1952 and window frames need repainting this summer. I think i will leave the walls as they are, not adding any boarding, just colour.

edit..thinking spaceboys question more, it would be better to add boarding, it is easier to hang something and looks better too.

[spaceboy]

May also add that little bit more weatherproofing ??? water & wind has a knack of finding it's way in places

[Ransu]

Yes, you are right in that too, i have also think of winter. Snow can also find its way in . And roll off roof needs also sealing system for wintertime.

[m.tweedy]

have you considered insulating the walls with something like this

Jablite Classic Board | House Insulation | Jabite UK

and then covering with pine wood cladding.

I have used this for my shed and it really does insulate well. It can also be used to insulate the underside of the roof.

Excellent stuff... used it for the floor in my build

What would the general consensus be on insulating walls causing the indoor temperature of the obsy after a day in the sun to be warmer than the outside temperature? I can understand imagers wanting a warm room and so creating a more comfortable and warm environment through insulation the extra expense could be justified but would it be worth it just for visual observing giving it may increase cool down times?

[yeti monster]

Excellent work Ransu, you make me want to do some woodwork when I get home!

[mag10]

I think spaceboy is absolutely right: In my opinion insulation on the walls and/or roof would be wasted ressources and energy, and ultimately unproductive. The shed is made to be used with the roof off. Insulation would trap heat in the daytime and just necessitate a longer cooling off period before the telescope could be used.

Mr Ransu, your observatory is a thing of sweet beauty. Well tought-out, solid, and built with great care and dedication.

I think it's marvelous.

Congratulations.

To a degree (pardon the punn) - it's the insulation in your house that keeps keep it cool in summer and warm in winter, so it could do the same in this situation, but given the thickness of the walls in a "shed" type building the insulation would not be thick enough to provide much advantage over not using any insulation at all.

[Ransu]

I think i will not add any insulation, there is no reason for adding. Shed and equipment can follow better outside temperature. At summertime when we have warm days, we can't see stars because of nothern countries ligt summer nights.

I was wondering also if my obsy needed any insulation- after all you want the telscope to be as close to ambeint temperature as quickly as possible?

[Gina]

IMO the observatory area does not want insulating. If you have a warm room, you may want to insulate that for the winter. If you do, don't forget the dividing wall.

Please do not take this as a knock at you as your's is not the first build I've seen insulated, but this is why I asked the question. You wouldn't really want it cool in the summer and warm in the winter (unless it's a separate warm room away from the scope). In the ideal world you want an equilibrium between the indoor and out door temperatures to minimize down time and increase observation/imaging time. Going of what you are saying if the insulation isn't going to be thick enough to provide much advantage why run the costs up by adding any at all?? I would rather my money spent on good winter clothing that can be used at dark sites or star parties when not in my obsy. Dose that make any sense or am I just rambling

[mag10]

Insulate the warm room by all means (and the more insulation the better).The only insulation used by Mr. Ransu was for the below-ground concrete base of his obsy because at 59 degrees North, the freeze-thaw cycles can heave up such structures.

As for the obsy itself, not only are professional observatories not insulated, the newer ones actually have a wide open concept (see photo of Gemini North at Hawaii) to minimize cool-down periods. They are also painted white or silver to reflect as much of the heating rays of the sun as possible. Mr. Ransu's obsy has a nice corrugated tin roof, and the exterior walls are of a light colour that not only match his house, but are perfect for reflecting sunlight.

All in all, a very nice project.
