I am looking for a light bucket to do spectrometry.

If the [stellar] image is not pin sharp onto the spectrograph slit
then energy is wasted and exposures become exceptionally long. Sharp
optics are needed and an efficient blazed grating producing a bright
1st order spectrum.

Maurice,

I am assuming that Celestron/Meade optics are reasonably sharp. To
keep my tracking errors to a minimum, I want to keep the weight down.
I have emailed some of the distributors of the Celestron products, but
have received varying numbers for the weight of the Carbon fiber
OTA's. Many of the websites also give conflicting numbers for the
Carbon fiber OTA's. I was hoping to hear from some Celestron owners
(or previous owners) to get the actual numbers.
