SCT Carbon Fiber OTA Specs

I am looking for a light bucket to do spectrometry. Because the SBIG
SGS is designed for the Meade/Celestron SCT, I am restricted to these
options. My highest priority is aperture vs weight. I have an APO
for visual observing, so quality of optics is a low priority.

I am strongly considering a Celestron carbon fiber OTA. From what I
can gather, they are significantly lighter than Meades, although I
can't find the spec for the 9.25". Does anyone know the weight of the
9.25" Celestron carbon fiber OTA? Does anyone have experience with
any of the other Celestron (8", 11") carbon fiber OTA's?

Thanks,

Daniel Cervantes
