Hi John I was with Dave observing one night when we did a bit of a comparison between his 12t4 vs his 22mm panoptic barlowed. This was in a 10" f5 dob.
The nagler didn't look bad until we compared with the barlowed panoptic, which was much much sharper.

I have mentioned this over on CN and some others have noted that they didnt think the t4's were as sharp as some others. Others of course said there is nothing wrong with a t4. I guess its not wise to draw conclusions on a sample size of one, but I'd love to repeat that test with another 12t4.
