Does ZWO have an opinion about powering 12V dew heaters (2 units simultaneously) into the ASIAIR? I have been advised against it by some users, but others say it works fine. What is the opinion of ZWO? Is there a risk to the integrity of the unit if the dew heaters draw too much power? My dew heaters are fairly small - for a 30mm guide-scope and an 80mm OTA.
