The difference nobody shows you
Same sky. Two telescopes.
Magnification claims on the box mean nothing without context. Pick a target and see what each scope actually puts in the eyepiece — framing, detail and reach.

Why you can trust it
Every scope earns a Polaris Score.
One transparent number from 0–100, broken down into the things that decide how a telescope actually performs — not a single opaque star rating, and never pay-to-play.
Scored on what matters
Performance, ease of use, portability, and upgrade potential — weighted for the way real people observe.
Every score breaks down
See the sub-scores behind the number — no black box, no single mystery star rating to take on faith.
No brand pays for placement
Reader-funded through affiliate links. Manufacturers can’t buy a ranking, edit a score, or remove a review.

Fast, Slow, and f/Numbers: What Focal Ratio Actually Tells You
f/4 is the fast one and f/10 is the slow one, and nothing about the notation tells you why. Here is what the number actually measures, and what changes when you put your eye to it instead of a camera.

Why Do People Put Filters on Telescopes?
