C14 OTA question


aa6ww
 

I currently own a CG-11 with an immaculate G11 mount. I have been
getting some aperature fever and have been considering selling my C11
OTA and purchasing a new C14 OTA.
Can anyone tell me if the c14 OTA would be pushing the limits on the
G11? I'll mount a Telrad on top with 2" nagler eyepieces and
2" diagonal off the back.
How much more shake or vibration would I see. I currently have no
noticible vibration what so ever and my scope seems increadly sharp
and solid.
Finally, can someone tell me the dementions of the trunk the C14 OTA
comes in, since storage is always an issue.
Would buying the OTA from Anacortes or similar places be ok or is it
wise to go thru company 7 and let them fully test out the OTA first
hand?

Thanks in advance for any help, Ralph

Hello Ralph,

I have a CM1400...the storage case is approximately 36 x 22 x 22
inches, considering the latches. For my two cents worth, I've heard
you'd be pushing the envelope by placing a C14 on a G11. I have the
CI700 mount and am having it retrofitted for better performance.
Others have mentioned that the C14 works best with a quality
mounting such as an AP1200, GM200, Paramount, and the like. However,
some of us (myself included) simply can't afford to buy one.

Vibration could be an issue for open field use dependng on
atmospheric conditions, A.K.A. wind (I have my CI700 in an
observatory).

I've bought a few scopes from Astronomics, with a few returns due to
factory defects. I think I read here or elso where that Celestron
doesn't sell as many C14's as their other models, which means they
take more time and care in their construction, resulting in higher
quality going out the door from the get go for the C14's. I can say
that the C14 I bought new from Astronomics was, and still is a
superior OTA. They'll have to pry my C14 from my cold dead hands!

If it cost more money to have a reseller "check - out" the scope
before buying it, I'd pass on it....that's what OEM customer service
is for.

Hi Ralph. I have used the C14 with the G11 for two years. I think
the G11 is really excellent, but it is pushing the limit. It is
really good for visual use. Damping times are very short, and
tracking after alignment with the polar scope is excellent. However,
it is not good for CCD imaging. I have done some (see Ken's pix in
the files area) in Fastar mode, and with a 3.3 reducer. I generally
stack 30 second exposures which works OK. Exposures at longer focal
lengths or longer than 30 seconds are almost impossible. Of course I
use the scope in the open with no protection from the breezes. If it
were used in an observatory it might be OK.

This sounds great! I was considering purchasing a C14 optical tube for
visual use only. Ive never had an interest in astrophotography and
specifically, the C14 would be for visual use either on my patio in my
back yard or at the dark skys of my star party location.
I would just have a telrad attached to the optical tube, in addition
to my 2" diagonal and nagler eyepieces.
Is the Optical tube really 50 lbs or 45, as I have read in some
literature?
Thanks again for your help.

Id like to also hear from other C14 owners using a G11 mount!
