  This eyepiece has good optics and a nice quality finish. Using this with my ED80 and it gives a very crisp image. Works very well on the moon with the 3x barlow. The 14 is also very good and amazing on clusters. I think Altair should offer a price for a complete set with a Barlow.

  This is now the eyepiece of choice for the moon and clusters for my 5" refractor and binoviewers. The on-axis sharpness is particularly good without the expense of losing details at the field edge. I can easily pick out the smaller features such as small craters and subtle details on the Lunar mare. A lot of my enjoyment has to do with both the eye relief, and fact that this eyepiece is very tolerant of one's eye placement, so viewing is less fatiguing. The field is flat, carrying detail rather well to the edge. At almost 70 degrees, the field more than large enough for most observation.

  The performance of the 14mm version in my Wave 102mm Triplet is superb. Contrast, flatness and colour are very well controlled across most of the field just as described. There is no flaring or internal reflection. The bright limb of the moon doesn't wash out views of the dark side, which is subtly illuminated by earth-shine. I live in London, and haven't had a chance to test this eyepiece on deep sky objects yet. That such a complex optical device can be manufactured for such a low price never ceases to amaze me, and I believe the premium designation is very well deserved. I will probably have the complete set quite soon. Well done to Ian and Nick at Altair for launching this new range to complement their refractors, and thanks for providing such excellent astronomical equipment at such a reasonable price.
