I have two Naglers; 17T4 and 9T6.
Until the 10" Newtonian arrived I would have to say that I was rather underwhelmed with them in the 8" LX90. The 9T6 in particular is generally useless in that scope in suburban skies. Too much magnification.
Different story entirely with the Newt. While they are both superb in this scope I have no plans for more Naglers. They are definitely 'warm' as far as viewing goes.
I've been looking for an excuse to try a Pentax but already had most of the focal length range covered. Whilst I have an 11 mm TV Plossl a longer ER ocular in this focal length range would be nice. Ergo, the 12 mm XF Pentax comes to mind. Price seems right -$215 from Frontier Optics (

Daniel handles the Pentax range so you might like to drop him a line.
