Objective (lens): A critical lens or set of lenses in telescopes and microscopes responsible for forming an image of the viewed object.
Focus (image): Represents the main point of interest in the image, pivotal for clarity in observations.
Eyepiece (lens): This lens serves to magnify the image generated by the objective, enhancing details for the viewer.
Eyepiece Focal Length: Defined as the distance from the principal plane where parallel light rays converge into a single point; crucial for determining magnification.
Objective Focal Length: Similar to eyepiece focal length, it refers to the distance at which parallel rays of light converge for the objective lens, influencing the telescope's overall performance.
