In this context, the 'off-axis' refers to a point that is not on the central axis of the optical system, like a star situated at the edge of the telescope's field of view.

Possible solutions include employing an optical design with a narrow field of view, inserting a field corrector or coma corrector in the optical path, and using a mirror with a parabolic, rather than spherical, surface profile.

Imagine you're looking at a dot in the center of an optical device like a microscope. Because this dot is right in the middle, it appears as it should. But as this dot moves towards the edge of the view, it starts to stretch out and blur, finally resembling a smudgy comet. That's coma aberration at play!

Coma aberration can greatly distort the perception of light through an optical system. It is more pronounced for object points farther from the optical axis and for rays farther from the lens axis. In complex systems like telescopes, the cumulative effect could cause substantial distortion.

Coma aberration is an optical defect where an off-axis image point appears distorted and comet-like, instead of a point. It occurs when light rays from an object point don't reconvene in a single point after refraction by a lens or reflection by a mirror.

'Coma' in coma aberration comes from the Greek word koma, meaning "hair". It refers to the fuzzy, comet-like appearance of the distorted image caused by this optical defect.

It causes point sources, like stars or distant city lights, to appear with a tail or 'coma', especially towards the edges of the photograph, affecting sharpness, resolution, and contrast.

Coma aberration can cause off-axis stars to appear as elongated streaks or comets in telescopes, leading to mistaken interpretations of celestial data.

The influence can be compounding in more complex systems like telescopes that have more than one lens or mirror. While each optical element in the system may not generate significant coma, their cumulative effect could cause substantial distortion to the final image.

Coma aberration refers to an optical defect that results in an off-axis image point appearing distorted and comet-like, rather than a point. It's pretty much an observational phenomenon in object-point imbalances.
