Excellent quality at an extremely good price Primarily bought this for use with my Lunt50/350 bp 400. It is identical to the Lunt eyepiece n all but name. However it is significantly cheaper. Well made, smooth operation and crystal clear viewing at all settings. Very comfortable on the eyes. (29/03/2019) David - Swindon
