Hi, We've got a SBIG STX 16803 and paramount MEII setup. We've noticed consistent issues with condensation in the observatory over summer months and failure of our equipment during these months. It is bad enough that the equipment gets visibly wet. Just wondering if there are any limits on the amount of moisture the equipment can handle (recommended humidity / temperature ranges)? Thanks,
No specific limits, but for the camera I can make some simple recommendations. When not using the camera, shut down the cooler, but leave the camera powered up. This will keep the camera slightly warm, which should help reduce condensation. I'd also recommend recharging the desiccant annually.
Unofficially, temperature and humidity should not exceed about 30-35C operating, and ideally 10% to 85% relative humidity (non-condensing). Water in and around a camera body is a bad thing - and expensive for any electronics. Some tips from other customers: - keep a 40W incandescent light bulb under their scope and mount when it is covered, to keep the air a bit warmer. - dew strap on camera body, focuser, and mount electronics box which is set to keep them about +5C above ambient - air conditioner / dehumidify in observatory structure
