An interesting combination of a classic dew cap with stray light protection, enhanced with the function of a spike mask. Dew is often a real problem on clear nights. After just a few hours, the optics start to fog up, making observation or photography impossible. A good dew cap reduces the risk of fogging and thus extends the observation time.
The Spike Mask is a simple and effective tool that can add a dramatic effect to images. It is a good choice for those who want to have the Newtonian spikes in their astrophotography images without having to deal with image post-processing.
Lateral stray light is also kept out. Stray light, for example from street lamps, reduces the contrast and often causes unwanted reflections in photographs. Replacement caps are really black on the inside. Stray light cannot penetrate the telescope in the first place.
ATTENTION: The TauSpike mask is intentionally very tight to prevent movement of the mask during photography, which can lead to double spikes in the images. Always remove the mask from the lens before switching off the Seestar.This dew cap fits the Seestar S50 from ZWO.
