This item is out of stock but you can place an order now and we’ll ship when it becomes available.


The anti-dew heater strip is an accessory that is user installed on the front of ASI cameras to prevent the collection of dew on the front cover of the cameras.

This  kit includes a zip-tie, the anti-dew heater strip , a Y-power cord and two spacers.

The “Y” power cord is designed to connect in-line with the cooler power supply cord, so the addition of the anti-dew heater does not add an additional cord to your imaging system. It connects very close to the back of the camera.

The thickness of the spacers is 0.3mm and 0.5mm. They are used for aligning the camera and ZWO's electronic filter whee..

We recommend supplying the anti-dew strip with 12V at 0.35A  DC power. The heating power on the strip is ~4.2 watts. You can use the same power cord to supply power to the anti-dew heater and the on-camera cooler, but make sure not to exceed recommended amount of Amps
