Hi, I have just joined this group. I use CG-5 (new wersion with ball
bearings). I have already cleaned the mount internally and polished
aluminum bearing surfaces as described on the Jeff de Tray web page
(AstronomyBoy). I am planning to replace clear plastic washers with
ones custom-made from 0,5 mm Teflon tape - lets see the improvement!
I am also fiddling with the drive electronics - will post some
details in the future!

Hope there are some other users... to talk to :-).

Regards,

Pawel Lancucki

yup ..
are you talking about the G5 from celestron? if not, can you
please explain which telescope you are using? for me, i have
terrible experiences with the G5s CG-4 mount. Whenever i track,
the counterweight has a tendency of hitting the tripod .. thats
why i change the latitude adjuster to a higher latitude

No, I mean CG-5 mount, which is a "next step" from CG-4, but all the
same rules apply. I may not experience your problem because:

1) CG-5 may be different
2) I live at 52 deg North.

I am not sure what exactly is your problem, using GEM (German
Equatorial Mount) you will always hit the tripod with tube, but not
always with counterweight.

If it is the shaft, than probably the mount was not designed to be
operated at your latitude :-(. If it is the counterweight, you could
try to swap it for a lighter one, which will be located further from
the mount head (although moving conterweight further makes the scope
more sensitive to vibrations).

Let me know more details, so I may be able to help.

Pawel

icic ... is it fun living at such a high latitude?
is the cg-5 good? does it have a pier? mine doesnt, maybe thats
why mine will hit the tripod. i also think mine is not designed
for use at lower latitudes

Difficult to say, the Polaris is quite high and there are many
circumpolar constelations. On the other hand, some nice sights (like
Scorpio and Sagittarius) are always low in the south, and are
difficult to catch. Based on my experience from holidays, I would
prefer to observe being around 30 - 40 north :-).

In terms of CG-5 - it is not bad, can carry up to 8 - 10 kg but you
need to spend at least a number of evenings to make it usable - check
the AstronomyBoy web page. Factory purchased, it is equipped with a
flimsy and poor alu tripod which should be replaced by wooden or
pier. For good piers, check Orion Telescopes from UK (there is
another group regarding Orion telescopes) - there are descriptions of
original Vixen mounts and various Orion - made accesories. On the
orion telescopes group there is a lot of discussion about these
mounts.

If you are tight on budget, go for CG-5 (new wersion with ball
bearings) but be prepared to spend some time with it! Otherwise, I
would recommend Vixen GP (up to 7kg) or GP-DX (up to 10kg) - they are
more expensive but better build and smoother in use.

Regards,

Pawel

is it fun having circumpolar constellations? wont you get to
master the constellations that way and you can know them by
heart more easily that way right?

Well, while "below" Polaris the visibility may not be good due to the haze
near horizon. Anyway, Southern sky seems more interesting - there are not
that many interesting objects near the North Celestial Pole. Where do you
live?

Well,

I live in Poland, Europe. Not a dream place for astronomers - dense
population, too much light pollution, high percentage of cloudy
nights (well, otherwise I would have to guit my job ... ;-) ).

Business consultant - not much time left for observations - instead, a lot
of "armchair" astronomy (reading books and magazines). Still at least 2
nights a month are a must!

Just completed a number of modifications and they seem to work:
1. The flimsy aluminium tripod was replaced with an extra stable ex-
theodolite hardwood tripod - this beast is dam heavy but vibrations
dampen in 1 second on concrete and may be even better on grass.
2. The original dual-axis drive was modified. I have added a hand-
controller unit with diamond-pattern direction buttons and direction
reverse switches as well as both red and white map lights. Also, it
can now be powered from AC or 12V. Of course, I cannot cure backlash
in the gearbox but at least the use of the drive is as convenient as
it should be!
Will post details with pictures and diagrams in some time.

Regards to all brother souls using the "could-perform-better" mount!

Hi every1.

It seems very likely that I'll soon be a G5 owner, but I still have
some questions:
1) How long does this scope take to cool down?
2) Will I need an adapter to mount the G5 on a vixen GP?
3) Is a moon filter necessary to watch the moon or isn't it that
bright in a 5" scope?
4) I've heard stories about the supplied diagonal not being very good.
Is that true and if so, what is a good alternative?

I hope you're not bothered by all these questions. If you are, just
tell me and I'll go bother someone else. ;-)

Jarno (another European 52 North observer)

As the new owner of a G5, I've taken my time in learning the various
features, polar alignment, etc. But the manual does a poor job
explaining the proper use of the setting circles. I kind of know that
they are for, but is there a proper way of setting them up. For
example, polar align the telescope and then set the R.A. wheel to "X".

Thanks much for the info. Really love this scope so far, Was going to
get a 8" Celestron, but the 5" is really nice to haul around, allowing
MORE viewing time.

Depends on indoor outdoor temperature change.  45-minutes is ballpark.

Don't know.

On the full Moon I can't even get my eye near the eyepiece.  Use moon
filter or better yet a variable polarizer.

Yes, plastic diagonals are often out of line.  You can test: lock
scope on polaris.  Put 25-mm eyepiece into diagonal.  Loosen diagonal
and swing it 180-degrees around the visual back.  Look through -- if
Polaris is gone that diagonal is junk.  Any metal diagonal is
probably better -- get something from a name brand store like Orion.

Polar align.  Point to known star.  Set RA circle to coords of star.

*Announcement of NexStar-5, G5, C5, C5+, & C5 Spotter Stolen
Telescope Database

Unlike a lot of stolen scope listings on the web, this one is
targeted toward the Celestron 5" SCT series.  The listing is part of
*The Unofficial Home for Celestron 5" SCTs* web page and draws
traffic from the *Celestron 5" SCT Webring*. Visitors to these pages
have a specific interest in the types of telescopes listed in the
database.  A listing placed here *will* reach a set-of-eyes on the
lookout for your scope.

The page with the listing also has advice on record keeping, dealing
with the police, and recovering the scope yourself.  If you've had a
5" SCT made by Celestron stolen from you, go to the URL at the bottom
and submit to the database.  Even if nothing turns up it can't hurt.

Don't rule out listing a long-ago stolen scope on this database.
Interested persons are drawn to the *Unofficial Home* and *Celestron
5"* Webring when considering used as well as new purchases of
Celestron 5" SCT telescopes and accessory items.  So even if a scope
was stolen 10-years ago, it may be up for sale (Internet auction
site, tag sale, etc.), leading prospective buyers to the page hosting
the database in search for information.  It is also possible that a
long-ago theft is now in "honest hands," that person may see the
listing and contact you.

For the complete database, check-out the listing on the *Unofficial

It will be interesting down the road to see how the new 127mm Orion
Apex Mak compares optically to the C-5.  The initial reports look
very good.

Hi All,
      I'm a new member here, and I've had the trouble you're talking
about with the star diagonal  on my scope(C5+).  It's out of
collimation, and the Antaries mirror SD I got to replace it with is
mis-aligned.  Last week I ordered a Lumicon mirror diagonal
that, I expect, will solve the problem.  I'll keep you posted.
Does anybody have any opinion about the Reducer/corrector that
is available?  Does it help for visual?       Thanks.        DavidT

I did a test recording eyepiece field-of-view with and without the
R/C.  I also did a report that diagrams the fov when the R/C is used
for prime-focus 35-mm photography.  Both reports are on the
Unofficial Celestron 5" SCT page:
http://www.pietro.org/Astro_C5/c5_&_nexstar.htm


Anyone have comments on the Celestron vibration suppression pads and
the C5 class scope?  Seems since I embedded E-bay's auction of
Celestron accessories on my site, there is always a set of
suppression pads on auction.  If they are so good -- why are people
getting rid of them?

Thanks for answering, Pietro.  I couldn't find the article on the
Red. Cor. on the web site.  There's SO much information!  I
heard the corrector vingnettes when used for photography ,
leaving a circular
image,but I don't know if it is noticable while viewing, since the
eyepiece view is circular anyway.
The pads are used by a guy in my astronomy club for
photography and he says they make the scope settle down very
fast after you touch it, but I would think, just for viewing, that
they
would just be one more thing to carry, and forget, when you
leave.  He also said they dampen the vibration when you're
walking around the scope, while shooting,on a concrete pad,
although I didn't
know that would happen.  He must be shooting at very high
powers.
Do you know of any knobs available to attach the C5+ wedge to a
tripod?   I have a tripod for a nextar but the bolts holes are the
same as the wedge, and it works for the C5+ too. I've just been
using bolts and a wrench.  I got the lightweight field tripod, and
for photography, it really needs to be tightned up as much as
possible and transported assembled because normally it's
pretty shaky.  Afteh wrenching it down, and weighting it down, I
think it will work, but it would help to hand tighten the bolts on
the wedge with knobs after polar aligning.  The ones for
attaching the telescope base to the wedge are too thick for the
holes in the wedge to tripod attachment.  Could it use the same
one's as for the C8?
I hope everybody is having a great Labor Day holiday here in the
states. Just two more weeks till new moon!

I am considering the purchase of a G-5 and I am comparing it to
Stellar Vue 80mm f6 refractor. Can anybody let me know how your G-5
works regarding 1)planetary and 2) deep sky. I am interested in
observations - not tests tests tests star tests etc. Real observing -
and not the moon!!

Want to know:

1) Saturn and Jupiter observations - can you see division in rings??
Bands on Jupiter? Red Spot? Moon shadow transits on Jupiter?
2) Deep sky. What does Andromeda, Orion nebulae, and Ring nebulae
actually look like in a G-5??

Thanks -

Hello Mark.


I'll take that your referring to the Celestron SCT 5 "
scope, If this is correct I can inform you that I have
one which I purchased last year at the PSSG  start
party from Astro Stuff(Rex). i have good results from
it in looking at Saturn, Jupiter M13, M31. i do not
have any pictures of them due to was doing just
visual.

I used the scope few times due to I have a C11 scope,
However very portable and as far as eye pieces and
what you will see will depend on what eye piece you
will be using. Even due I'm selling it now due to be
purchasing a small refractor Tak FSQ 106, I still can
say it is a good scope and have not had any problems
with it.

The 2 web sites that convince me to purchase it were
these: http//astro.isi.edu/c5plus/ and
http://www.asahi-net.or.jp/~RT6K-OKN/c5e.htm

Go to them and see for yourself, Hope this helps you.

Yes - the Celestron G-5  5" CST.

What did these objects look like - how bright/ contrast/ - what is your
description of the deep sky objects and the planets???

Hello Mark.

As Far as the Magnitude, I would have to guess on this
with some of the deep sjky and don't want to guess.
the few times when on a very clear night M13 you would
see it very bright. This past July when mars was at
its close distant, even with the haze I could see very
good image mars when compare to a Tak FS 102 refractor
with a 9mm nagler next to me.

When looked thru. the refractor and thru. my G-5 there
was a diference however not a really big spectacular
diference.I was using a regular 25mm Plossal eyepice
on my scope at the time. On saturn and Jupiter you can
see good images also  and the Moon very good. This is
was I was concentrating on at the time with polorizer
filter. Great contrast also.

As far as other Deep sky objects on the web sites I
mention before you can see some of them.

Mark,
I have a C+ which is the same thing on a different mount.  I also
have a Starhopper 14 inch Dob.  I love them both and cannot
decide many times, which one to take to the astronomy site, an
hour out of town.  They're pretty close in views and one is as fun
as the other.  It depends on my lazyness and how long I plan to
spend there. I had a C8 years ago and the C5+ seems as bright
and contrasty, just not as magnified for planetary use. Globular
clusters do not resolve as well as they do with the 14 inch but
they still are very easy to spot and look quite good in the C5.  You
sould have an easy time searching down and viewing all the 110
Messier objects with the G5, after you have already had an easy
time moving and setting up the scope.  If you camp, as I do, and
space is a consideration, the G5 is perfect.  It will go on a plane
with you, if you just cary the optical tube in a camera bag and
pack the mont, if you need the mount, It  works great in the
daytime too, something a C8 just would not do, nor the Dob!
Five inch apeture is about the minimum size to resolve deep
space objects according to the Edmund Scientific Mag 5 Star
Atlas, which shows MANY things to look at with that scope.  Oh,
Andromeda looks great with a 32mm eyepiece, and Orion
Nebula looks great with a 16mm.  M13 needs a 10 or 12mm.
Also, get a better star diagonal than the one that comes with it if
it's anything like the one I got.  I bought a lumicon the other day, it
should be here this week.  But I don't think I'll ever sell the scope.
It has been too usefull so far, and will also be great for CCD
imaging in the future.

With the R/C I don't find any vignetting with 25mm eyepieces or 35-mm
camera.

I replaced most of my C5+ tripod/wedge hardware with new bolts and
wingnuts.  Cheaper than finding knobs! Just bring a sample of each
bolt to replace to hardware store to find matching wingnut.

The tripod is shaky unless you tighten the bolts where the legs meet
the head.  But the head sockets are plastic so I loosen the bolts
after every session to prevent cracking.

I decided on the Stellarvue 1010 3" refractor. Why? because 100% of
the owners said it was awesome, surpassed expectations, had great
views of planets and DSO, and they are assembled and tested by the
owner of the company. I had narrowed it down to the Celestron G-5 or
Orion 127 Mak but became convinced that the 80mm from Stellarvue will
equal or surpass the 5" scopes in image quality and product quality.
There seems to be little variance in the Stellarvue scopes quality
other that great to awesome. Not so with the G-5. Plus, the Orion is
not available until October! For less than $700 I got the scope, hand
assembled, f/6, rave reviews from owners - no negatives, heavy duty
eq mount that all the owners like (not undersized like some G-5
owners remark on their mounts that came with scope), oversized and
overengineered focuser, laser dot finder, and upgraded 9m and 32 mm
eyepieces plus 2X barlow and star diagonal not prism, plus shipping.
If I can't see what I want to see I can return it for a full refund.

Thanks for the input. Additional comments are welcome like I made a
mistake, the G-5 will really perform better, etc. You can change my
mind if you have a serious issue.
