Also have some Naglers (bought used too) and they are sharp & work very well, depending on the scopes being used.
L-R: Naglers 9mm (T1), 12mm (T2), 5mm (T6)
The Nagler 5mm does not provide sharp-focus with my 8" SCT/f10 because it yields too much power (400x); it's more suitable for other scopes in the stall like the refractors (2.5", 3", 4", 6").
What focal length is your Nagler? Have you used it on any other scopes (like refractors)? Thanks.
