Astronomy for Beginners
A Glossary of Terms from Celestron 🚀
Aberration – defects in images produced by a telescope (or optical system). They are caused by limitations in the design and manufacture of the optics. Find out more about aberrations here.
Astigmatism – an off-axis effect that causes rays from a star to come to different focal points in the vertical and horizontal plane.
Coma – a spherical aberration caused by photons striking a plane off-axis. When an image suffers from coma, stars appear as little, off-axis, comet-shaped blob
s that point inwards towards the center of the field and get bigger as you look towards the edge of the field of view.
