I'd recommend a remote temp/humidity monitor. I've got one like this with a remote under my TeleGizmo 365.

I have a light bulb for humidity control. I'd like to hear how the dri stick performs.

The corner bolts are actually 3/4" threaded rod cut to lenght with a hacksaw. The rod and the nuts were bought from Lowes. They are standard zinc plated hardware. I will be keeping the pier covered with a Telegizmo continuus exposure cover and a dry stick (both on order from Scopestuff). Hoping that will keep any corrosion at bay for a long while...John




The dry stick is called "Dri-Rod Dehumidifying Heater Rod" on the Scope Stuff website.

Thanks JJK. I should have been more accurate in my wording. I thought about using a light bulb but was a little concerned about their fragility. The Dri-Rod is more robust and not too exepensive so I'm giving it a try. The one thing I'm not sure about is whether to leave the bottom of the cover open to allow air circulation or whether to try and seal it off around the base. Any thoughts on that? Thanks...John

No problem. I added the real name & link, because the ScopeStuff website isn't fun to navigate.

The Dri-Rod makes more sense than a bulb for several reasons.

I'd first try out the Dri-Rod with the bottom of the cover somewhat open, and check to see if the equipment is sufficiently dry. It would likely depend on whether the equipment has dew/frost on it at the end of the observing session.

Yrs, if it performs well enough, it probably does. Early on I looked at Dri-Rods but was a bit concerned they didn't really have the wattage needed to quickly dry out the area I needed. I beleive they where made to keep the inside of a closed gun safe dry. My target area is under a Telegizmo 365 cover that is not sealed and is fully exposed. That's why I asked for info on how it performed. I might switch over from by 60W bulb to a Dri-Rod, but I'd like to get a first hand report first. Right now it's been raining off and on all day here. I have my light buld on under the Telegizmo cover and my remote sensor is reporting 58% humidity. If the rain stops it will be around 40% in the morning. I think that's pretty good. If a Dri-Rod will do as good or better I'll switch. If it can't then I'm happy with the light bulb I've been using for 2 years now.
