Dew Shield for ZWO Seestar S50 Telescope Accessories for ZWO Seestar S50，Only Compatible with TPU Made Cap Cover and Bahtinov Mask Focus Black

Inexpensive and simple addition to a Seestar S50 to reduce lens fogging from dew. The S50 does have a dew heater, but having passive protection is a plus. Obviously, care must be taken when installing or removing the dew shield to avoid any damage to the drive mechanisms that position the telescope, but it slips into place with reasonable ease. It provides the same sized opening as the opening on the telescope, so you could install a filter or mask at on the dew shield just as you would directly on the telescope. The other issue that requires caution is to avoid accidentally trying to close the telescope arm when the dew shield is attached, which could also potentially damage the drive mechanism.

Very good and nice

lots of dew in South Florida. This really does the job, have used for hours with no dew forming on the Seestar s50 lens. Great product.

We live in the 4th largest metro area in the US--light pollution is very bad. This shield does help contain stray light contamination of your images, but of course, does not reduce "sky glow". At least in my hands, so far, the Seestar S50 seemed to struggle a bit more to track/auto-guide with the shield on than when it was off. The 2nd magnitude stars probably restricts access to guide stars in the smaller field of view? Overall, it works and is worth the cost.

I love it for solar add the solar filter and then mount both together for night photography keeps neighbors ligh from leaking into the image prevents unavoidable side lighting

Came scratched up already. Seems to fit ok with the addition of little foamy thing around it. Will test tonight. Worried about reflectiom from the glossy material used.

Real tight, and forgot it was on the first time I used it, but no damage done!

This works great with the Seestar S50. Helps block out the street lights!
