Question for N.I.N.A. Users

How much dew you do or don't get fully depends on your climate. As an area gets near the dew point thats when you can expect it to form. Dew heaters are the most common way of dealing with dew and if you use something like a Pegasus Powerbox you can have it monitor the dew point for you and automatically control the heaters.

Dew shields are another common way of passively controlling dew but YMMV depending on how bad the dew gets. You also have to keep in mind that dew shields add a notable about of size and weight to your setup which can effect guiding performance if any wind is present.

You can keep your control PC in some kind of enclosure to keep dew out. I wouldn't worry too much about the ports on the mount that have a cable plugged into them. For any open ports you can always cap or otherwise cover them to help keep moisture out.

Like reg said, keep power supply, PC etc…in some sort of cabinet or container. I find the rest will be fine. In saying that,  my roof is automated to close at dawn with a small hoist motor and rack / pinion …diy job.
On occasions, some mornings there would be heavy dew on equipment but generally on those mornings are nice and sunny, so I open the roof for a couple of hours to dry out. 
if I was to do it again I’d use a sliding gate motor, relatively easy setup.


note to above: it’s the first thing I check in morning be it Remote Desktop or look out the window 😉

Agree with the above. I just put towels over my boxes and electrical connections that I'm concerned about. Let the dew settle on the towel(and it will!)

Or, I have purchased two mini USB fans that I set up near the electrical and let the air move over them. The oh so small amount of air current keeps the moisture off.

I also have a small foldable laptop tent that the laptop sits in. That way dew settles on the fabric.
