Scope/accessory storage guidelines
« on: December 29, 2017, 10:48:19 PM »
I recently finished building the first telescope that I have ever owned, a 4.5 inch f/8 Newtonian. Now that I have been taking it out for observing on clear nights, it matters more to me where and how I store it. I have a few questions that I would like to get the voice of experience on.

For context, I live in rural Northeast Iowa where it gets very cold in winter (-20F worst case) and hot and humid in the summer (90F and thunderstorms).

Can I store my scope outside on a large covered porch? This seems like it would give me the best thermal adaptation and I could carry the scope down into the yard easily. (I can lift the scope and mount in one arm.)

Can I also store eyepieces outside or do I need to keep them indoors and only take them out for observing?

How thoroughly do I need to cover the aperture and the rear end of the tube? Do I need to be concerned about sealing it TOO tight and causing moisture problems?

Thanks in advance for any suggestions you can offer.

-Neil

I like to keep my eyepieces inside, especially in the cool months, so that they are warmer than the air. Keeps them from fogging up as easily.
Dry is the big key tho, last thing you want is mold growing on your optics.

I also keep my optics inside. My EQ mount, tripod and other hardware can go in the garage.

Depending on your scope, you could get something like this to plug up the eyepiece end during storage-

I have similar end caps with desiccant packs in both of my scopes.

For the eyepieces, I would keep them inside in a nice case for long term storage. On a night where you plan on getting the scope out, set the eyepiece case out next to the scope on thecovered porch so all the temps can equalize.

Good advice above...Pelican makes a variety of great cases that can secure your eyepieces. Not the least expensive option but a good long-term investment to protect your eyepiece collection. As for your scope, a dry and secure location with a good cover (for dust/dirt/bugs and moisture) with some ventilation would be my approach if I were in a similar cold and high-humidity location.

Best,
Ed

Assuming that it's genuinely rainproof and that you're not worried about the scope being stolen, a covered porch seems absolutely ideal.

Seeing as wind-driven rain can get just about anywhere, I for one would feel more comfortable with a tarp over the telescope.

Like everyone else, I would store my eyepieces inside. There's no reason not to.

I keep 3 telescopes and all my accesories in an unheated garage. Quick and easy to deploy and alway at or near ambient temperature. Anywhere that is well protected from rain, snow dirt and dust should be fine. Typical backyard observatories are not heated or air conditioned.

I don't have the space to store my scopes in the garage (we're one of those crazy families that keeps our cars in there rather than using it as a storage locker) but even if I did, I'm not sure "ambient" is a word I would use.
In winter, it always seems to be at least 5°C warmer than outside, and in really cold weather the delta can be 10°C or more. In summer, the west-facing double doors pick up a ton of heat in the afternoon and the inside of the garage can get really hot.
Come to think of it, I should probably spend a bit of time pondering both those problems because that's gotta be impacting my home heating/cooling bills.

http://www.dictionar.../browse/ambientI said at or near ambient temperature. Within 5 degrees of where you will observe s a LOT closer than the interior of your house. Warm up or cool down will take a very very very short time compared to bringing the scope from the house.

Mine is well ventilated so it does not get crazy hot like a metal storage shed sitting in the sun.

If you want to think about thermal shock, mine rises and falls slowly with the weather and is always ready to go. You take yours from something inside to something outside and want it to acclimate in an hour. Big thermal change in a short time.

Remember, backyard observatories are rarely heated or cooled. And I expect the same can be said for the major observatories too.

Andwhat with moisture,it does not damage the telescope? I have unheated garage too, but I keep my instruments inside the house. Temperature different inside/outsidein winter-20º,in summer-0º.But we have a lot of rain by us in Netherlands.

All those people who have backyard observatories seem to do pretty well. Unless you think they are all running heaters in their observatories 24 hours a day.

My garage is dry enough. If I lived in an unairconditioned house it would be not be significanlty different from keeping things in the garage. And in the winter the air is naturally dry.

I would think the optics go through a lot more thermal shock going form a 70 degree F house to a 20 degree F telescope than if they were at ambient temperature already and all the time.

Whatdo you think the humidity range is OKtokeep telescope stored in a garage?(Dob and MAK)
I have to measurehumidity in my garage..

Again I point out that if your house were not air conditioned then your house and your garage would be at similar humidity levels in the summer. The Garage is likely dryer in the winter.

If you don't have mold growing in the garage you should be fine. If you don't have rain dripping in, you should be fine.

If your garage is wet, you need to fix your garage anyway.

No,no,no,there is no mold at all, thank you for your advise. I amjust worry, because the air outside/inside the garageis the same, and outside we (a lot of rainin Netherlands)have high humidity. Need to figure out with telescope maker I think..

Yes, a lot of tools, boat electric motor, no problem yet with it, probably I'm paranoid..
