2" diagonal in FS-78??

Looking hard at a TAK FS-78 OTA. A question came up about whether it would accomodate a 2" diagonal. The details on this scope were vague in this regard at both Anacortes and Astronomics. Todd Gross mentioned the need for additional hardware. Don't want to go buy a premium 1.25" diagonal when there's a 2" MaxBright and a great 40mm Pentax XL waiting to go in.

Have heard this scope is somewhat limited in in-focus travel. If additional hardware IS required, I don't imagine it will improve the in-focus situation any. Does anyone have any experience using 2" diagonals in the FS-78?
Thanks.

The NEW FS 78s are a bit shorter than the ones made about 2 years ago. Contact Texas with your serial # and ask if it is the shorter one. If the serial # is 99#### or lower don't bother. The shorter FS78s will work with "most" eyepieces and the 2" diagonal. The older ones will work with "some" 2" eyepieces.

Thanks
