I've owned the 16 t6,13t6,14 xw
The 16 is /was a great eyepiece really flat in my 12"5 but the eye relief is very tight sold it at a fair loss as I rarely reached for it in time ,The 13 t6
is a nice piece of glass ,small ,compact and that wide view .Not long after I bought the 13 I had the opportunity to compare it to a 14 xw , no paracor , I had owned a pretoria for a number of years then , I guess its down to personal preferences a lot of the time and for me at that time I instantly thought the 14 was the better of the two , still remember that sinking feeling I'd backed the wrong horse
what did u buy ?
