Say it ain't so...
So far, the only solution I've found is to order the OTA and GT-5 Goto mount separately. Why would Celestron make such a choice? Considering how durable Carbon Fiber is compared to Aluminum tubes, for ~$100 more, it seems nuts not to go with CF. Any word on this? Orion --- Outgoing mail is certified Virus Free.

Any word on this? Orion Hi: They've had problems finding a steady supply of carbon fiber tubes, I know that.

Have you heard anything about internal condensation problems with
the carbon fibre tubes? Possibly due to its insulating properties leaving internal humidity only the optical elements left to condense on? HI Chris: I certainly have not had this problem with my carbon fiber C11, despite using it in some _really_ humid environments. I also haven't heard anything of this kind reported on the NS11 Yahoo group... Peace, Rod Mollise Author of _Choosing and Using a Schmidt Cassegrain Telescope_ Like SCTs and MCTs?

Considering how durable Carbon Fiber is compared to Aluminum tubes, for ~$100 more, it seems nuts not to go with CF. Any word on this? The NexStar 9.25GPS that I am currently reviewing has a Carbon-fiber tube. I worry about a sharp object hard impact which, on an aluminum tube, would only dent things and remove some paint, but with a Carbon fiber tube, might actually punch a hole in things. If I had been Celestron, the aluminum tube would have been my choice, despite the mechanical considerations. Clear skies to you. -- David W.

worry about a sharp object hard impact which, on an aluminum tube Hi David: Maybe this could be a problem. But I've yet to hear of anybody sustaining tube damage of this kind over the--what?--three plus years the scope's been around. I really can't see a downside to the carbon fiber tube. 'Course, the jury is out on how it will hold up over the long run...but I suspect "very well." Peace, Rod Mollise Author of _Choosing and Using a Schmidt Cassegrain Telescope_ Like SCTs and MCTs?
