Zoom Eyepieces & Kits

A zoom eyepiece covers a range of focal lengths, typically 8 to 24 mm, in one barrel. Turning the ring changes the magnification without swapping eyepieces, which is ideal for planets, where you want to find the highest magnification the night's seeing will allow, and for outreach, where you do not want to hand someone a dark telescope while you change parts. Eyepiece kits bundle several matched eyepieces, sometimes with filters and a Barlow, for a complete start.

We carry the Baader Hyperion Universal Zoom Mark IV, Celestron 8-24 mm zoom, SVBONY SV135, SV191, SV230 and SV245, Lunt zooms and flat-field sets, Tele Vue accessory packages and Celestron eyepiece and filter kits.

Zoom Strengths and Limits

  • Narrower field at low power: Most zooms show about 40° at the long end and 60° or more at the short end.
  • Convenience: Perfect for planets, the Moon, solar observing and public events.
  • Barlow combination: A zoom with a 2x Barlow covers a very wide range of powers with two items.
  • Kits: Good value when starting out, though one premium eyepiece often outperforms a full budget set.

Zoom Eyepieces: Frequently Asked Questions

Is a zoom as sharp as fixed eyepieces?

A quality zoom like the Baader Hyperion comes close in the centre. Fixed eyepieces still win on field width and edge sharpness.

Can I use a zoom for solar observing?

Yes, behind a proper solar filter or a dedicated solar telescope. Zooms are popular for H-alpha observing.
