    I was just looking at Orions EF 8mm 60* widefield for $89. Agena has what appears to be identical under BST for $69. Hmmm. Then there is the 7mm X-Cel LX right in the middle at $73. (Agena) I'm leaning to the Celestron X-Xel LX.

    The Celestron X-Cel LX are an improvement over the old X-cels, which I have and like. You may want to consider the Agena Starguider Dual ED at $60 each, which get very good reviews in other forums. I had a couple of the BST eyepieces, marketed under another brand, and didn't like them. My samples had soft views and noticeable scatter.

    I'm pretty sure the StarGuiders are BST (Barsta). My 15mm StarGuider is pretty nice, but faster than about f/6 and there is EOF astigmatism.

    I think I have on of these.
    It is a AstroTech 12mm flat field.

    They might be BST/Barsta flat field.

    I can see it now. It would make sense as Orion source a lot of their eyepieces from Barsta.
