Guys!

Got the polar scope today! The box was pretty smashed on one end but
luckily that was the end with the most bubble wrap on it!

I'll look through it tonight and see how it looks!

Re: Polar Scopes Don't Fit

Joseph G. Ewing, MD
 

My new polar scope won't screw in all the way either; but I'm not necessarily
taking that as bad news. As tight as the threads fit, I'm thinking that the
polar scope is well aligned in its tunnel at the center of the RA axis. I
was able to center the reticule with the tiny Allen wrench to move the tiny
screws in and out. We have not had clear skies since the polar scope
arrived; so I don't know if the alignment will work with the GO TO.
My hunch is that it will work great. An added benefit may also be being able
to able to rotate the polar scope in the *tight* threads to attain the right
position to line up Polaris and the one or two other stars without having to
rotate the mount on the RA axis. The polar scope seems tight enough to
maintain concentricity in the tight threads. In some instances this may be
preferable to moving the whole RA around its axis. Maybe this problem is a
solution and a blessing in disguise. What do you think?

Roland,

What is the outside diameter of the 65 mounting rings for the AP155 f7
Starfire. Or another way, will a AP155 fit on the LMDSBS (10" center to
center) with a Celestron C11? Can they be mounted side by side?

Thanks Andy


Re: Mars with good air

Bobby Middleton <bobm@...>
 

Thanks Tim. I think I found the source of my ring reflections. They appear
to be caused by a bright outer edge on one of the corrector elements. I have
made a small "baffle" out of a black piece of paper which will hide that
bright ring, but I have not tested it yet. .

Re: 900 GTO case

Jeffrey D. Gortatowsky <mrrockets@...>
 

Richard, (and others),
Could you take digi-pics and upload them so we can see how you laid out the
mount and scope in the various cases?

I was going put the two pieces of the 900GTO in a single 1650. But now I am
thinking, even if they fit, that's too heavy. I have a 400GTO head with
sliding plate adaptor in a Pelican 1650 (which has wheels BTW). In that same
case is the counterweight shaft, 5" rings attached to a sliding bar, the GTO
box, cables, and hand controller. That's just under my pain threshold. So
now I am thinking two 1600's or 1650's.

Ideas? Also, it looks like Orion's SCT tripod case (the one that lets you
keep the wedge in there as well) might work nicely to carry the 54 pier,
legs, turnbuckles, and center piece.

Clear skies,
Jeff

Re: Mars with good air

Hi Bobby,

Great images! Keep up the good work.

Your image taken on 10 June 2001 is close to my EP impression of Mars (AP10"
Mak-Cass) this past Friday night/early Saturday morning (local time).
Unfortunately, the seeing here was only about 5.5/10. Although the smallest
features were not quite as distinct as shown in your CCD image, the
difference in the contrast of the features w/in the Syrtis Major region was
really quite stunning in the EP.

It's been frustrating waiting for clear night skies here.

Clear, Steady and Dark Skies,
John

Hey Bobby,
Great image. Looks very much like the image in my 130EDT last night. I am
glad to read your observation regarding the dimishing polar caps and that
you also noted little haze on the limbs as that was my experience last night
as well and I was concerned that my viewing skills were not up to par.
Congratulations and keep up the great work.

Jeff,

Congrats on the new mount. Very good about Big Bear; wonder if it got
cloudy there at nights?

Eight boxes, man that's alot.
I can imagine reading the manuals without the mount present would be
difficult. Thanks for the heads up concerning the clutch knobs!

We probably could swing something where we could get these APs side by
side and also do some astro talk, I'd be up for it.

Tim,

very well packed. Yours may be more or less depending on what you
ordered. I
got a 54 pier, some extra mounting plates, etc.

I was due for a well earned long weekend/getaway to Big Bear with my
wife.
So only the manuals went with me. Wednesday night I had only enough
time to
open the boxes and do a quit check that everything 'seemed' there. I
did not
have time to put it together or plug it in. I got home today (Sunday
June
10th). It's pretty hot in the garage right now so I will wait till
around
sundown to actually try and set it up and plug it in.

I took the manual(s) with me to Big Bear and read them while sipping
wine on
the lake. In fact I read the 900GTO's manual twice as the hand
controller
manual is the same version 2.6 manual as my 400GTO's as far as I
could tell.
So there was no point (AFAIK).

So far, the manual seems straight forward enough. There are a few
'weak
areas' where, without the mount in front of you, the descriptions
about
turning "this screw" and lining up "that mounting" hole, gets dry
and tough
slogging. Since you and I hope the mount arrives set for 30-45
degree
latitude range, and I think it does, we'll not have to play with the
altitude adjuster bar and such anyways. I suspect there is no
glamour way to
describe the adjustments. :)

The whole clutch/damper thing is a bit confusing without the mount
in front
of you and your scope mounted. Heads up, resist the urge to play
with the
clutch knobs until you read the manual. Supposedly they come "firmly
hand
tightened" to give you a feel for the mount's movement when properly
"hand
tightened". Like I said, read the manual before loosening them if
you are
interested.

The damper knob's pretty glossed over. I gather it's use will become
'apparent' once I have the scope mounted. I don't mean to imply
there is
anything wrong with the manual. It's fine. It's just there is five
or six
paragraphs on using and setting the 'clutches'. There is a single
three
sentence paragraph on the 'damper'. It's not clear why anyone would
use the
damper knob if one follows the clutch instructions, etc...

Otherwise, I suspect, unless there is an 'infant mortality' failure,
I'll be
as trilled with the 900 as I am with the 400. Bloody work of art if
you ask
me. Now I have to figure out how to case it and such. And now the
5.1" will
look small compared to the mount instead of the opposite! :)

It should be fun to get them side by side some evening.

Clear skies,
Jeff

Mark, Roland, Greg, Larry, and Paul,

Thanks gentlemen for your input, greatly appreciated and I
think the setup of the AP-900 won't be much hassle.
I will take an ax (have to avoid the 'chainsaw astronomy)
to some of the roots and clean this up.
(did that last year and the roots seem to be back in force)
I'll end up placing the Pier in position, then RA, DEC axis
and OTA all seperately. Really looking forward to using
this mount.

As for a video, sounds like a good project. I know someone
in the business and I think she could get it into budget for
only a few million dollars. I would, of course, be the star
of the show and maybe Roland and Marj could be my co-stars.
Would prefer to film in Spain, with some lovely countryside
there as back drop.

Thanks Again All! ...and I promise to read the manual!

Hello Wolfgang and welcome to the group, I just got my AP 900GTO a
couple of weeks ago. It's really awesome.

The Pelican Case #1650 has wheels, too. The 1620 will definitely be
too small, as I used all the space available in the larger 1650 for
the components and there wasn't any space left over. You have to be
careful and take some time planning the space, however.

I purchased the tear-away foam insert. There are three layers, one
thin one on the bottom that's not divideable, and two more rather
thick foam sections, (the same width and length as the case but less
that half the depth) which allows for very nice placement of the
components. The RA axis went through both layers, but the dec axis
only needed the bottom layer cut out. Having said that, I had to cut
out the top layer to accomodate the electronics box on the dec axis
but by keeping the cut out portion, I was able to re-insert most of
this above the rest of the dec axis and secure a very tight fit once
the dec axis is in place. Similarly, the counterweight shaft only
sits down into a cutout in the top layer. My dovetail plate slips
into a nice small thin cutout through both layers.

Unfortunately, my digital camera is at my wife's office and I can't
take a .jpg for you.

It's a work of art when it's done, but only a whisper of the beauty
of the mount itself.

Good Luck

I took my mount to a local camera shop and the 1604 was a nice fit with room for
the counterweight bar, counterweight, keypad, and electronics. I may order some
foam too to make a really tight fit. Scheduled to receive Monday. I ordered this
because its smaller size seemed perfect. I also use a Pelican 1502 with dividers

new on this group

Wolfgang Valentin <valentin@...>
 

Hi,
i am new around here and wanted to introduce myself shortly. The reason why
I entered this page is a 900GTO that i own since Nov 1999. I use it with a
6"/f3000 schaer refractor built in the 70ies with a Fraunhofer optics by
Lichtenknecker and a 4"/f10 Apo. The Schaer is quite a heavy construction
with a mass of 25 kg (60 lbs, if i am correct) but the mount can manage that
easily. I live in Vienna, Austria so i have to move out for my observations
which i do in 2 different ways:
1) i benefit from a location of my parents-in-law 1 hour away from Vienna by
car with very little light pollution but rather unsteady weather; i store
the schaer there permanentely and
2) going to certain places around Vienna with the Apo which is much more
transportable. If you travel westwards from Vienna you soon come to
elevations up to 1000 m and there are some good places known among the local
stargazers.
No need to say that i am very content with the mount, which outperforms
other i have tried before by far and in any respect (technically and
aesthetically, IMHO).
I have been watching the site now for 10 days or so because of a polar
alignment matter and found the ug be very useful and sometimes pretty
entertaining, too. hope i can make a positive contribution on occasion, too.

BTW, in my impression, most of the members seem to be from USA; is there
anybody out there geographically close to me?

Clear skies to everybody,
Wolfgang


Re: 900GTO just arrived!

Louis,

Was there ever any doubt? <VBG> I was in Richmond last night with a good
friend trying to image, clouds on and off, finally packed it in at 3 AM. I
called Martin around 5 pm yesterday and he said that two fellows had just
left with their AP900s, you must have been one of them. It is a great mount
and handles the C11 much better than I had hoped. The polar scope will ship
from C7 Mon. and should be in my hands tues. Good hunting and enjoy, you're
almost in heaven!

Steve

ps...if you find someone that needs 2 pier adapters, mine is available as
well!!

I just picked up my new 900GTO from Company 7 this afternoon. I just
want to echo what others have said; this thing is a work of art! I
was surprised to feel that way, since I've seen the one that's on display
at Company 7 dozens of times; but when assembling the mount, you really
get a sense of the quality workmanship that goes into this fine
mechanicanical marvel.

In case anyone is keeping track, I did receive the polar alignment scope
that I ordered as well.

Oh, and the way this thing was packed for shipping was quite impressive,
too! It's safe even from UPS :-)

I just want to thank all those other folks that have just received their
new mounts and telescopes recently; I think that you've got the clouds
completely distracted from my place, 'cause there's not a cloud in the
sky. One hopes that the clouds aren't on the mailing list and that I've
just given myself away :-)

Can't wait for the sun to go down; this is the first clear weather we've
had here in a couple of weeks, and I hope to get a glimples of Mars
when it rises above the trees I have in the east.

Also, like Steve Reilly, I've got an Astro-pier, and the 900GTO (and
pier adapter plate) fits on like a glove; now I need to see if anyone
wants to buy the G-11 adapter for the pier that I probably won't get
much use from now the the 900GTO has arrived.
