It is probably a bit early for the 6mm, but the 8mm has been out for a while and I would be interested in any comments by those who have tried it.

Hi Michael,
So far I find the 8mm to be as good as the others. Nothing particularly distinguishing about it, just another of the series. Works well, good details and is quite light.

I find it to be an excellent performer, like the others I have (4, 5, 7, 9). Actually the 5 has a little CA off-axis for me that the others do not for me at f/4.7.
Performs very well at f/4.7 staying clean to all but the extreme edge as I recall - a little soft the last 5% I believe. Yesterday had it out observing Moon with f/11 refractor and was astonishingly crisp to the very edge.
