I've had the 14mm for a while Eric, and report that it is my favourite eyepiece in my Mewlon 210 by far. The views are identical to a friends Ethos 13 in the same telescope. No aberrations that I can easily detect (Mewlon DK design aside) and comparable in every way to the Ethos for day to day viewing. When used with my Tak refractors it's just fantastic as well. Sharp to the edge.
Whilst I run a 2" heater strap it's rarely needed - it just doesn't seem to dew up much.
I've heard how to wash it down, and will give it a go shortly as there is a little eyelash grease left on it after a public night recently. Should be fun.
