What is ACF telescope?
ACF (Advanced Coma-Free) is an altered version of the Meade’s previous schmidt-cassegrain telescopes that replaces the traditional spherical schmidt-cassegrain secondary mirror with a hyperbolic secondary mirror.
What is coma in telescopes?
Coma is an aberration that occurs predominately in reflectors and manifests itself in the appearance of ‘comet-shaped’ stars with their brightest portion pointing towards the centre of the field of view. Coma increases with distance from the centre of the mirror, which means that the aberration affects off-axis light.
