What are the key differences between a refractor and a Newtonian telescope, and which one would be more suitable for observing celestial objects?

Alright, buckle up buttercup. A refractor telescope uses lenses to gather and focus light, while a Newtonian telescope uses mirrors to do the same job. Refractors are great for sharp, high-contrast images but can be a pain in the celestial behind to keep chromatic aberration in check. Newtonian scopes are more budget-friendly and better suited for observing faint objects in the sky. Ultimately, the best telescope for you depends on your preferences, budget, and how often you want to throw down with maintenance.
