The huge 110° field of view offered by the Lunt Engineering 5mm HDC eyepiece, together with excellent contrast will leave you more than impressed after first light. The excellent engineering and fully multi-coated lens surfaces are suggestive of eyepieces costing much more. Features of the eyepiece are low chromatic aberration and excellent contrast. The lens edges and internal spacers are fully blackened allowing flaring and ghosting on high-contrast objects to be eliminated.

The Lunt Engineering HDC range of eyepieces are Nitrogen filled and waterproof. The 5mm features a 1.25" Nose with optional 2" filter sleeve allowing use in either 1.25" or 2" diagonals. Both size options are threaded for filters and it is possible to use the 2" nose together with a 1.25" filter. The rubber eye cup may be removed to reveal an M44.5 x 0.75 thread. This allows the eyepiece to be used for Afocal photography.

We feel this 5mm Eyepiece is well suited to use with all telescopes where high magnification views and wide fields of view are required.
