Air Moisture, Dew, Frost, - Care & Storage

Being new to astronomy, this morning was my first experience with huge amounts of moisture on my equipment once I brought everything inside from the outdoors (temperature around 30 degrees with loads of frost outside).

It's easy enough to wipe off the optical tube case, mount, tripod, etc. with a paper towel, but what does everyone do about lenses and eyepieces? Although they didn't frost up outside when viewing this morning, when I brought all my equipment inside my house, the opticals all fogged up. I know just leaving the moisture on them can't be good for the opticals, but I don't want to scratch or damage the EPs, etc. either. Any suggestions would be appreciated.

Also, on another storage issue, at the present time, I leave my Skyview Pro 120 EQ refractor set up inside my house and when I want to view from my backyard, I first take the tripod and mount outside, then take out the optical tube and assemble the scope. I was giving some thought as to leaving the tripod and EQ mount outside permanently and keeping the tube only in my home when not viewing. I was thinking about keeping it stored in one of those large Rubbermaid sheds that you see at Wal-Mart and Home Depot. I though perhaps placing a large black "Hefty" bag over it, while stored inside the plastic shed would protect it from moisture and dirt. This would certainly make setup a lot easier for me. Does anyone have any thoughts as to this idea for storage? Being outside in Pennsylvania during the winter, it would be exposed to cold temperatures, but I would think moisture wouldn't be much of a problem is covered up (maybe with a blanket, then a plastic bag) while stored in the Rubbermaid shed. I use the scope any night we have clear here in Pennsylvania.

Thanks for all your suggestions.

Bruce,

I make a product called the Opti-Dry for the inside of cases, corrector covers, etc., designed to absorb moisture. Please go to my website AstroProProducts.com (I am an Astromart vendor) and you can get all the details there.

Also, another AM vendor Particle Wave Tech makes a nifty gadget called the Desicap. Used in combination the Opti-Dry unit and Desicap will help tremendously.

Now, here's a question: What if I don't have a case or bag or box to put my scope in when I bring it in side?

I recently got an 8" SCT, and after being out in the cold (New York) it foggs up when I bring it in. I just let it sit on the tripod and let it naturally warm up -- I don't wipe anything, then put the caps on the next day.

Am I running to risk of doing harm?
