Good for dew prevention, but…Once this heater has been fitted, it would prevent you from accessing the desiccant tablets for drying them out or replacing them. If you have reason to access the tablets and need to open the front of the camera, you will damage the heater strip and would need to replace it with a new one. Suggestion: ZWO should make it slightly smaller in order that the screws on the front of the camera are not covered by the heater.

Excellent service by FLO

I bought this tape to tidy things up rather than using a dew tape around the nosepiece of the camera , just installed yet to test my only gripe and maybe flo could get lynx Astro to make a better Y lead using silicone cable as the zwo y lead is too thick a cable cable ties are to thick , both male leads are the same size rather than offsetting the lengths just looks untidy and cumbersome , will probably lose the Y lead and use separate cables to plug into my Deepskydad Hub2 , would recommend the dew tape but the Y lead could do with a bit more thought putting into it.

Strip is easy to fit to camera I have only used it once so far and gets warm didnt get any dew
Not sure why the two spacer rings are in picture because they dont come with it but it looks like it will do the job

I bought this add-on for my ASI1600mc-cooled as I had a session that was badly affected by condensation on either the camera window or the sensor. I have fitted it according to the instructions and have had no condensation issues in the next imaging session. However, due to dust getting onto the sensor when I dried the desiccant tablets, I find it very difficult to access the camera front plate screws as they are covered in the self-adhesive anti-dew heater.
So, in conclusion, I'm sure the device works well, but could be designed to allow access to the body screws for all the intended ZWO camera models.

I purchased this after experiencing heavy dewing on my 294mc pro camera front window. It is a great piece of kit. Easy to fit and works a treat. Have had no issues with dew forming since. A very worthwhile investment.

We had a few nights with crazy humidity a couple of weeks ago. I brought the dew heater with the camera, but didn't added on camera. That was a mistake because I ruined one night of imaging because of dew. Yes, the 1600MM Pro still has this issue under certain circumstances.
