Used my XW 7mm for the first time in my Stellarvue sv80ed on the moon and it was just magic,then barlowed it with both the 2x and 2.5x powermates to give 3.5 and 2.8mm with no degredation whatsoever in sharpness,contrast etc,the neutrality of the XW's is second to none and added with the viewing comfort ,awesome.
