Go to a star party try a 5mm Nagler and compare it someone's 10mm Radian in
a 2x Barlow. No wait. You actually have this stuff. I know, try using
them first, then decide.

In the end, unless you need money for food, you can't accumulate enough
astro stuff...

I may have too many eyepieces for my XT-12, 1500mm focal length, f4.9.

Included in my eyepieces are a 10mm Radian and a 5mm Nagler Type 6, and, a
TV 2X Barlow.

Do I need the 5mm, or, will the 10mm with Barlow provide the same results?
Views through the 5mm are really crisp and bright -- will I lose anything
with the Barlow?

Thanks.
