Vixen SLV Eyepieces: 20mm, 12mm and 6mm Firstly I ought to apologise for the fact that i) this report has been some time coming and ii) that it’s not as long and thorough as some of the excellent reviews that have been posted by others recently. Nevertheless I hope it’s of some interest for anybody interested in these new Vixen eyepieces. I also hope I've got the history of these eyepieces correct - please let me know if you spot any bloopers and I'll gladly amend the piece  Around about 1994 V
