Q1. How do I choose the right eyepiece for an object?
Generally, choose a low-power eyepieces (e.g., 25–40mm) for wide views of star clusters or to locate objects. Mid-range (10–20mm) is great for planets and the Moon. High-power eyepieces (below 10mm) are for close-up detail but may be affected by atmospheric conditions. These numbers may require an additional barlow lens for low focal length telescopes.
Tip! Use our Telescope Field of View Calculator to work out the relative field of view of an eyepiece through a telescope.
Q2. How do I clean telescope eyepieces?
Great question! Avoid cleaning unless necessary. If you notice smudges or dust affecting your view, blow off loose dust with a soft air blower. Use a lens brush for stuck particles. For smudges, use a few drops of lens cleaning fluid on a microfibre cloth or lens tissue, gently wiping in a circular motion from the centre outward. We recommend the saxon Optical Lens Cleaning Kit.
Q3. How should I store eyepieces when not in use?
Keep eyepieces in a protective case or pouch to prevent dust, scratches, and moisture. Always replace caps after use, and avoid storing them in humid environments to prevent fungal growth.
Q4. Can I use filters with eyepieces?
Yes. Most 1.25" and 2" eyepieces accept threaded filters at the base. Screw them on gently and make sure they are clean and scratch-free before use.
