TEYOUYIDew Shield for ZWO Seestar S50 Telescope Accessories for ZWO Seestar S50 not Included SeeStar S50 Telescope Black

Just what the doctor ordered. The dew shield fits snugly to the opening for the telescope lens. Maybe a wee bit too snug, but stays in place and helps keep extraneous light from entering the picture. Worth the money.

It fit like a glove.

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.

If you use masks OR a filter/mask holder for your seeStar, you'll need to file the inside of this dew tube shield.I used a curved file and five times around on the inside of the opening looking at the sky did it, and the mask/filter fits fine now.

It arrived promptly in good condition. It is nothing more than a hollow-plastic tube designed to screw into the SeeStar for dew protection. Have not had a chance, yet, to use it.
