Hi Nils,
I have both a 20mm T2 and 20mm T5 Nagler which I have used with a TV Big Barlow and 2" PowerMate. The quality of image, especially with the PowerMate, is excellent in an NP-127, C9.25, and 12.5" ZOC.
Unfortunately I've never used an AP Barcon with either of these eyepieces. I can only tell you that the PowerMate works well with both these eyepieces. I doubt you'll notice any degree of degradation unless you're using very high quality optics on a great night of seeing.
Clear Skies, Bill

Has anyone ever tried this combination? I'm trying to decide between the barcon and a 2x powermate. The powermate will work, of course, but the lighter weight and lesser magnification of the barcon is appealing. Anyone have any experience here?
thanks,
Nils
