Ensure Proper Desiccant Drying
When drying the desiccant tablets, make sure you bake them at 200°C (392°F) for at least 2 hours.
After drying, quickly install them back into the camera while still warm to prevent moisture absorption from the air.
Let the camera sit for at least 24 hours before use.
Use the Camera's Anti-Dew Heater
The ASI6200MM has a built-in anti-dew heater. Ensure it is enabled in your imaging software.
If it’s not sufficient, consider using an external dew heater strip around the camera.
Adjust Cooling Strategy
Instead of cooling the camera rapidly to -5°C, try a gradual cooldown (e.g., step down by 5°C increments over a few minutes).
Sudden cooling can cause condensation inside the sensor chamber.
