Hi Geert, Very nice set-up indeed!

What make mount is this again? I don't think I've ever heard of this one!. Tell us a bit about it please?

From what I can see in the pic, your set-up uses tube rings, instead of what most people I see use, the Losmandy Dovetail Plate. Mark

Hello,

after a few months of negotiation with the former owner and thinking,
I got the second-hand C-14. It checks out good mechanically and
optically as far as I can see after just a few nights use and
startesting. You can see a picture in the Photos section in my
album. The OTA is a black one, about 6 years old. I think I'm gonna
like this telescope!

Clear Skies,

Geert Vandenbulcke

Hi bruce,
Very nice pictures!

Do you got any pictures the c-14 rear focus gear-mecanick, so it
possible to see how it works close to the back of the mirrow..?
It would be nice, if you could download here too.

regards

Hi Mark,

I picked up a new C-14 a couple of months ago. In addition to the
newer color it does seem to be lighter and flop is surprisingly

good

although I have not peeked inside.

Pictures are here..



Regards,

Bruce

Hi Folks, It is my understanding that a few years back,

Celestron

had changed some things on the C-14 OTA. These being in

particular,

the Rear Cell, and the scope was evidently put on a diet, shedding
some weight in the process.

I don't beleive I have ever seen one, and I'm interested in

seeing

what these new C-14's look like, especially the back, and side

views

of the scope.

Can someone please post some pics in the file section of their

scope if it is a newer one? It would be greatly appreciated.
Thanks, Mark

Bruce, Thank you very much for the pics of your scope. Mark

Hi All,
Those Lumicon UHC filters just became collector's items.

I completely modeled a late model C14 using SolidWorks 2000 in
preparation for installing my patented moving mirror focuser
assembly. I plan to post some illustrations of the C14 workings on a
web page.

Hello,

I may acquire a second hand C14 and that is why I joined this group.
I would welcome advice, experience (good or bad) and any other
practical info you would like to share about this big SCT.

Thanks,

Geert

....planetary work. What have you folks done....

For planetary I use a Televue 2.4x powermate. That's about all the
magnification the planets can take.

what i do is i added counterweights into it. it is still not perfect

How did you attach the handle to the front? Just screwed it into existing
holes?

Also, though we have a full aperture Thousand Oaks solar filter, the
F-ration is too short for decent solar or even planetary work. What have you
folks done as far as creating stops to increase the F ratio?

Balancing the tube on the paramount. The RA axis is no problem thanks to the
counterweights on the other end. What have people done as far as adding
counterweights to the tube itself to balance out the
camera/filterwheel/reducer, etc. on the other end? I have the tube slid as
far forward as possible in the mounting rings, and it's still way
overbalanced on the rear end.

Good question! I don't use tube rings. I have mine on a Losmandy dovetail.
I have the OTA pretty far forward on the dovetail. Hanging off the corrector
end of the dovetail I have placed a Losmandy dovetail weight set. At ten
pounds, it's still not enough. I'm looking for ideas here as well.

Also, what are people using for pointers/guidescopes, and how do you have
them mounted?

As a "finder scope" I have an Orion Short tube 80 (80mm f/5 refractor) with
a PC-23 video camera hanging off the back. I obtained the ST80 used for $100.
A finder scope doesn't need fine optics.

My experience with unattended remote operation is that it is considerably
overhyped. Sure you can operate the telescope remotely with The Sky, CCDsoft,
kitchen sink, etc., but a local operator is still needed to do setup, make

it, I constantly find myself wanting to or needing to be at the telescope.

I agree. The fellow who built the observatory I now direct built it on the
foundation of remote unattended operation, but even watching him from a
distance over the last few years, it was clear that he wasn't going to
achieve that goal. My objective for the current school year is to get the
facility tweaked and running as much as possible on a turnkey status, and
get students and teachers out there using it.

A few issues I've run into:

I'll post more soon. I hope you guys don't mind my leaning heavily on your

You're not alone. :-)

I'm here and will be asking for some advice soon. I am the new director of
the Madison Metropolitan School District's observatory. We have a CM-1400 on
a Bisque Paramount 1100 in a Prodome. SBIG ST7 CCD and CFW-8. It was
originally designed to be used remotely from the internet. There are some
problems (understatement) with that type of operation and I'm strongly
leaning toward exclusive on-site use until I have a much better
understanding of all the hardware/software issues in remote use.

I'm a long-time amateur astronomer who was lucky enough to already work for
the school district (a school psychologist, believe it or not), so I got the
nod when the previous director (and observatory founder) decided to go back
to the classroom.

I'll post more soon. I hope you guys don't mind my leaning heavily on your

After I purchased the Losmandy dovetail I didn't get a chance to do any
shimming before...

Unfortunately, I now don't have my C-14 in my posession at this time.
It's been out of my hands for almost three months now. Another
member of this mailing list has it. I'd very much like to get it
back too. By this time now, I'm honestly and sincerely feeling
quite frustrated. I hope I get my scope back soon. It's a private
matter though, so other than mentioning the above, I won't go into
the details.

My dovetail is OK, I guess, but I've thought about getting the
Losmandy. Sometimes after tightening my screws, I find that I

can go

back and tighten them further, like the dovetail flexed or
something. Why did you get the Losmandy and how much better is

it;

what mount do you use it on? Thanks.

I purchased the Losmandy dovetail so that I would have somewhere to
insert shims needed to make the OTA orthogonal with the mount. I'll
be getting another dovetail for the topside so that I can mount

aother

equipment on top of the OTA. I'm using a Paramount GT-1100S.
