Product information
The Altair Lightwave TM 9mm Planetary Long Eye Relief Eyepiece delivers high power with a short focal length telescope, such as a small refractor, so it's ideal for high power planetary or lunar observing.
The 7-element, 4 group computer optimized design, a very smooth polish, and fully multi-coated optics deliver exceptional contrast and clarity. The 55° apparent field of view is flat, and well corrected.
20mm of Long Eye Relief means you can position your eye 20mm from the eyepiece rear lens, making this is a very comfortable eyepiece for beginners and experienced observers alike, whether or not you're wearing glasses. This helps you spend more time observing fine details on the planets or moon without fatigue.
Apparent field of view 55° degrees
Focal Length 9mm
Barrel OD 1.25" with filter thread
Fold-down eyecups & rubber grip
Eye relief 20mm
Design 7 elements in 4 groups
Coatings FMC Fully Multi-Coated
Baffled with blackened lens edges
Precision CNC machined barrel with extremely hard anodising.
Divide the telescope focal length in mm by the eyepiece focal length in mm to get the magnification.

Altair staff comment: "We have tested this product extensively, and when you consider the optical quality and the long eye relief feature, this is probably the best value eyepiece set in our range to date. We have been able to keep the cost down by using a simple yet robust barrel, and by incorporating optics which are already a popular proven formula. We recommend them for comfortable enjoyable viewing with all refractors such as the Starwave, Lightwave, Wave Series and Newtonian reflectors. They also perform very well in binoviewers due to the narrow barrel construction and light-weight housing. "
