It is a good choice for anyone who wants to have the Newtonian spikes in their astrophotography images without having to deal with image post-processing.To use the spike mask, simply attach the mask to the front end of the telescope.

Dew is often a problem on clear nights. After a short time, 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.It also keeps out stray light from the side. Stray light, for example from street lamps, reduces contrast and often causes unwanted reflections in photographs. A protective cap prevents stray light from entering the telescope in the first place.

The item is made from PETG using a 3D printing process and is dimensionally stable up to 80°C.
