NOVAStar LER Long Eye Relief 5mm Planetary Eyepiece 1.25" 55°

These high quality long eye relief eyepieces offer a suitable solution for those who wear glasses for observations.

The internally fully blackened construction and blackened edges of optical surfaces, together with the high quality, fully multi coated optical elements provide well corrected field and colour management.

Warmly recommended for our own NOVAStar Emerald ED80D and Emperor ED110D telescopes, but of course these eyepieces will work well in any high quality telescope. Remember, the image quality will always depend on the weakest quality optical element in an optical system.

On many (cheaper) eyepieces the foldable rubber eyecap is made from very thin material and would split after a few years of usage, but these eyepieces from Taiwan have a comparativel thick rubber eyecap, so the expectation is that these will surve much longer.

Depending on the actual focal length of you telescope, these shorter eyepieces (3mm, 5mm and 6mm) would usually offer high magnification for seeing planets and the Moon when used with telescopes within a range of focal length appr 500 to 1200mm. The longer focal length eyepieces (from 9mm till 18mm) would be similarly usable in larger telescopes, i.e. 10, 12, 14 or 16" Meade, 9.25, 11 and 14" Celestron SCTs and similarly sized Newtonians.

Above are just general ideas for usage, but we'd recommend to do some calculations for your own telescope(s), consider the maximum useful magnification, the conditions of the sky (seeing) and what you want to see with it. You can always call us if you need help with advice.
