Removing star spikes with Cuiv the Lazy Geek

Thursday, May 16, 2024 by Richard Harris

Star spikes, also known as diffraction spikes, are lines radiating from bright stars in images taken with Newtonian telescopes. They occur because of diffraction of light around the secondary mirror's support vanes, also known as the spider vanes. Refracting telescopes, which lack any central obstruction, do not suffer from star spikes and generally offer higher ...
