condensation in observatory

[Guest]

Update on dehumidifier that came today.

In just over an hour it has reduced 24% of the moisture ?? wow, with humidity outside at 95% this little machine set on eco is working wonders already.

Dome is bone dry and it's only using 300 watts.

Thanks all for the invaluable advice.

I have one of these Pulsar domes and agree they are a bit of a pain with regards to condensation but that’s fibreglass for you. I don’t use any dehumidifiers but have the telescope covered with a telegizmos 365 cover instead. This works okay for me. There have been times when I have been doing stuff in the observatory during the day (in winter) and discovered the uncovered telescope tube has fogged up. A high wattage light bulb under the tube soon clears this up.
