Star spike generators
Star spike generators for refractors. A star spike generator fits over the end of the dew shield. It adds four diffraction spikes to bright stars, like those from the vanes of a Newtonian. We make each one in Shropshire to fit your telescope.
Getting the right fit
Choose your telescope from the list, or enter your dew shield’s outside diameter. How to measure your dew shield shows how to get it right.
We’ll help
If your telescope isn’t listed, or its dew shield is over 200 mm, call 01743 224 180 or get in touch and we’ll make one to fit.
