ZWO ASI1600mm pro dew on sensor.

astroandy

My camera is about 11 months old but just recently when i finish imaging and take my flats i can see that there is a small patch of dew on the camera sensor so i placed the camera in the airing cupboard which seems to remove it after about 24hrs but then the next time i imaged it was back but not quite as bad would the zwo anti dew heater strip help or is this only going to help on the camera glass only that doesn't seem to dew up,temp this time of year is just about freezing or below i run the camera at -20 and allow it to cool down over 15mins so camera doesn't draw much power to keep it at -20 so would i be better running the camera colder to generate more heat to the chip?.

You can follow this guide and redry your camera.

I recommed you not cooling the camera too deep because the effect of cooling is margianlly when you set deeper cooling temperature.
