I originally wasn’t planning on heating the primary mirror as I read it’s less vulnerable to dew and a fan is sufficient to keep it at bay, but as I got a pack of these 5ohm ceramic resistors for the secondary mirror (they were larger than I thought) I used them on the primary. They are stuck onto the mirror with some thermal silicone just on the sides so they can be removed easy.
