Picking a first telescope can feel overwhelming. Aperture, focal length, focal ratio, reflector vs. refractor—what matters most? This guide cuts through the jargon and helps you buy with confidence.

Aperture is king

Aperture (the diameter of the main lens or mirror) determines how much light your telescope gathers. More light means brighter, more detailed views. If you can, prioritize aperture within a manageable size and weight.

Choose the right mount

Alt-azimuth mounts are intuitive for visual use. Equatorial mounts track the sky’s rotation and shine for long-exposure astrophotography. If imaging interests you, start with a solid equatorial mount.

Reflector vs. refractor vs. catadioptric

  • Reflectors: best value per inch of aperture; require occasional collimation.
  • Refractors: sharp, low-maintenance optics; great for Moon and planets.
  • Catadioptric: compact, versatile; excellent for small spaces and travel.

Our top beginner picks

For a versatile start, consider the LunaView 90 AZ for lunar/planetary viewing or the Aperture Pro 200 EQ if deep-sky objects captivate you.

Try before you buy
