Spike mask with dew shield for ZWO Seestar S50: star spikes and dew protection in one
This accessory combines two functions for the ZWO Seestar S50. The bahtinov mask creates striking diffraction spikes around bright stars, giving your photos a classic and professional character without post-processing. At the same time, the built-in dew shield keeps moisture, dust, and stray light away from the lens, even during long sessions on humid nights.
You mount the sturdy metal construction via the M62 thread, for example on an M62 base such as the Omegon Dust and Dew Cap. At 75 grams (2.6 oz), the whole setup remains light and manageable.
