Product information "EXPLORE SCIENTIFIC 52° LER Eyepiece 25mm Ar (Refurbished)"
Solidly in the mid-magnification range for most amateur telescopes, the 25mm is a true workhorse for visual observers. If you love deep sky observing, eyepieces in this focal length range not only give healthy increases in magnification, but the contrast enhancement of giving a darker background sky can make all the difference of how galaxies and nebulae appear under suburban skies.
Comfort, Quality, Value. The Explore Scientific 52° LER Series mid-range focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.
These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. The rubber inlet and the foldable eyecups make handling and using in the field easy. The patented EMD-coating produces high contrast images and prevents reflexes and ghosting. The argon purging effectively prevents internal fogging, and you don´t have to deal with dirt, fungus or cleansing fluids getting between the lenses. The eyepieces are sealed - this makes sure you will be able to enjoy these eyepieces for many years to come.

- General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device especially the lenses to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not expose the device to high temperatures.
