Have an issue with humidity - the interior of the obs gets dripping wet with dew some nights and when the lid is closed and the sun comes up, all that water evaporates and then condenses on the mount and mirror (which remain at night temps). Still working on that one - a vent did not help much and next trick will be to run the aircon again in the mornings to dehumidify the air as the sun comes up.
Long term, the disposable chloride laundry dehumidifiers seem to work OK when the lid is closed, provided there is not too much outside air making its way in.

Thanks for that Ray, i am thinking i will have to run a dehumidifier and maybe an aircon. i do have silver insulated wrapping on the ob walls and roof so i might just need ventilation for to maintain a decent temperature, but the dew has been bad recently. test and learn i guess
