Storing my mak?
« on: December 24, 2017, 04:53:53 AM »
So I've been maintaining my 127 mak in my garage so it's quicker to acclimate in chicago's beautiful winter weather.   Is it secure to do so, caps on and such?  Is this a bad idea in the summer when it becomes hot?  I am a bit worried about heating coming in and outside in the wintermonths,  but is this a good idea?  I believe that the cold will be OK, and I believe I should bring it inside for the summertime, but any guidance would sure be appreciated!  As always, thanks in advance!

<p>Yes, bring it in to Your summer for 2 reasons:
</p>

Heating and Humidity may cause Mold to develop on the inner surfaces.

The mirror is occasionally cemented to the corrector/meniscus plate, and the heat can cause the adhesive to fail.  Additionally, always store a Mak at the vertical position, together with front (notice that this is the way the expensive Questar Maks are stored in their cases), therefore there is not any strain on the secondary adhesive.  I looked at buying a used Meade etx90 that had such a collapse of the secondary adhesive.

Additionally, I would suggest getting some desiccant packs to store in any scope that's stored in storage for extended periods, in non climate controlled surroundings. .

If you're moving your scope from outside to the garage and the garage is the same temperature as outside, you won't get any condensation. That only happens if you move your scope from a cold place to a warm place. Now, if you've been outside for a while and dew has collected on your gear, let it dry before you pack it up and store it. When storing your gear outside, keep it in some kind of closed case or bag to keep dust and bugs away. Better if the case or bag is breathable.Don't worry about dew in the garage, either. The roof will keep dew from falling on your gear, and the dry floor will keep dew from evaporating and rising to collect on your gear.Keeping your scope in the garage in the summer will also help by making sure it's as warm as your yard when you want to observe. Image stability is ruined equally by a scope warming up to ambient conditions as it is by the scope cooling to ambient conditions. In the summer you'd have the added aggravation of condensation collecting on your scope when you brought outside from your air conditioned house.I'll bet your Mak is a Gregory design, with the secondary mirror being an aluminized spot on the inside surface of the meniscus corrector. No glue to fail, so I wouldn't worry about that. I stored my SCT vertically, but with the primary down. I transported it horizontally.I've stored my gear in my non-climate-controlled garage for six years without a problem. Other gear is now in my observatory, no problem there, either. Remember, even the Keck scopes are stored in non-climate-controlled buildings.

That's what I kind of figured, but it's always good to ask someone who knows. Is it a problem having my goto mount out there? Cold won't hurt the tripod, but the electronics might be a different story.  It's been so cold and/or cloudy that I haven't got out much, but this too shall pass. Thanks for the advice!

I have purchased stuff used off of flea bay and stuff in the south sometimes has mold, or haze on in the objective (s).
why is this?

What about going from warm to cold in a matter of hours. Could that cause condensation to form in the scope?
Is that worse than taking the scope inside an air conditioned house after a night of humid observing?

i keep mine inside my house when iam not using it its a show piece item, every house has something they show pc, like art, paintaings, ststues, coins, stamps, why not show pc your scope and just take it out to cool 1.5 hrs b4 viewing?
just my thoughts

Would love to do that, but my wife does not see the aesthetic appeal of astronomy gear.

Leaving electronics outside can be a problem. I have stored my go-to mounts in the garage and observatory for years without a problem so far. I don't think the temperatures will harm them. The moisture in un-air conditioned air can, and does, corrode the contacts where cables (like for hand controllers) plug in, though. Also, if any of your gear is battery powered, storage in cold conditions may mean it won't start-up when you want it to. Cold batteries are pretty useless.

The problem is even more pronounced if you leave your electronics outside under some sort of cover. There are several members here who leave their gear set-up in a yard, under a tough cover like the TeleGizmos 365. But they take measures to be sure moisture doesn't get under those covers: closing the cover around the bottom of their pier, installing low wattage heaters (20W light bulbs, etc.) or dehumidifiers under the covers, etc.

Regarding "warm to cold in a matter of hours":I haven't had a problem with that. I make sure my gear is dry when I put it away and I keep all covers, caps and plugs installed when storing. That way the OTA doesn't "breathe" very well while on the shelf. So even as the temperature rises and falls, the OTA isn't taking in new, humid air that will condense as the temperature falls. Keeping a desiccant pack inside the OTA (perhaps in the focuser), like pallikas suggests, is an extra layer of protection.

Taking cold gear into a warm, humid room will trigger condensation, so let your gear warm-up and dry before putting it away.

ok i see your point, your wife doesnt have her collection in the living room its probably in the walk in closet, so you cant have her items on display, unless you bribe her with an new pair of shoes or 2 if you can put them in the living room. Ok all joking aside if you cant then you cant that ok

My astronomy equipment all lives in the unheated garage so there is no warm up, no cool down and less tendency to fog up or to draw condenstation or dew during observatoin sessions. I don't think cold is going to bother the electronics as long as they are dry.

People who live in non-airconditioned houses have the windows open in the summer. Not much different than keeping stuff in an unheated, well ventilated garage.

People who have their own backyard observatories don't generally heat or cool them. They just keep them dry and well ventilated.

Having a case for telescope makes the temperature adjustment more gradual when coming in from the cold.

I store my Mak vertical so dust doesn't collect on primary or meniscus.

Oops I meant horizontal.

I would also be afraid of grease dripping onto the primary if stored face down.  I keep mine horizontal in a closet. If I bring it in from the cold I put it in a case so it heats up gradually. If there is no frost on the scope, I put the caps back on outside. Cold air (i..e freezing) is much dryer that warm air so I am not concerned about trapping moisture.
