>>I have a couple of Pentax orthos, 7mm & 9mm, that are just stunning in my f8, 4 inch Tak. How do these ep's do in a faster scope like the AP?>>
I have looked through these two eyepieces with an F6, and they do indeed work extremely well - very sharp eyepieces. They are not really short enough for good planetery views (you need about 200X for planetary detail) but they could be barlowed. In that case, they would be working at F12.
