Re: Help needed - Polar alignment for dummies

Dean Salman <cluster@...>
 

PemPro 2 works good from the time I have used it. Not crazy about
the setup to get you there, but it works. I do know it comfirms what
PAM does.

The trick to PAM is not to use the Next button feature, it seems to
have issues from what I have heard. Many I have talked to came up
with this method.

1. Telescope Setup use Sky Control (assuming you are using TheSky)
2. Set slew to only 5 degrees.
3. If you are pointing east, slew west. If pointing west, slew east
4. You need the GSC 1.1

(from this point I assume you are pointing east

A)
Point the scope to a star in the east and get it centered (more or
less. Then Sync to the sky.

B)
Click start, and the scope will move 2 times and take 3 images. When
you get the results, click the stop button. The last slew moves back
to the starting star

C)
Now move only one axis, I usually start with AZ. If you moved too
much so that the same star is out of the FOV, put it back in the
center (more or less) using the Keypad, then sync on TheSky 6 again.

Run Pam again steps B and C until the AZ is within 5 arc minutes.
Then do the same for the Altitude.

When you are withing 5 arc minutes in both directions, select the
slew to 15 degrees. (this makes PAM work better but harder to use if
you are far off the pole) and make final adjustments with each axis

I get within 15 arc seconds on both axis in about 10 minutes once you
know how much to move the mount. If you need more help, e-mail me
privately and I can help you more. I have help setup 3 others with
PAM and they all get withing an arc minute.

Ray is right that each run in PAM will give a new result, but it is
only within 1 arc minute.

That all said, if you have PemPro 1.1 you might want to upgrade to
2.0, it does work very well. I just would like to see a better setup
so you don't have to wait so long for it to get dark. If you never
rotate the camera, then you only have to do the setup once.

With PEMPro you should be able to (accurately) get to less than 1 arc-min in
about 10-15 minutes from the time you start measuring Azimuth error. Make
sure you are using Build 36, which is the latest version. There were some
important bug fixes that affected the altitude measurements. TPoint will
take hours and you usually get different Polar alignment results every run.
I haven't used MaxPoint for measuring polar alignment.

Seem to me that AP/firmware dev team needs to get a look now.
3 things to be address:
- allowed range (-180..180 or 0..360) for longitude
- Gg command returns for east longitude (355 50 for 5 50 ???)
- and more generally keypad to mount interaction (saving location to

No: unfortunately, the value written by PulseGuide is
_not_

properly after a power cycle if the longitude is East.
Last test I did was to set the longitude to W 6 50 then
change
the
longitude via PulseGuide to E 5 50, then click "send to

the

Then I inspected the longitude: back to W 6 50 - so the

I'd appreciate to have AP to check what is going on: I am

Re: Error in AP driver

John Winfield
 

Good work.

Presumably the longitude is used in the mount controller to determine
the meridian flip point, so it's not just a case of setting a value
which can be read back by the PC software and handset uniformly, but
also setting a value in the mount controller which it understands and
interprets correctly for flips to work.

Yeah, but the printed command protocol doc from AP indicates that it is looking for and giving longitude in a 0-360 format. I think the firmware author needs to chime in to solve this one......

Re: Error in AP driver

Pierre Henrotay
 

Ray,

I have autoconnect set to No and want to keep it as is; so the
location is prompted at every power cycle, which - after selection-
erases the value in the mount and sets it in the range 0..360, which
PulseGuide cannot cope with (-180..180)

See also my reply to John W.

Hi Ray,

This is Rev L. CP3 (this is a brand new Mach1).
In my latest tests, I used PulseGuide and only PulseGuide (1.30).

This is the exact sequence to show the value is not retained
after
power cycle:
- set the longitude to W 6 50 via the keypad for location 1
- power cycle
- start PulseGuide and get Site Long: all fine
- set longitude via PulseGuide to E 5 50, then click "send to
mount"
button
- observe that PulseGuide reads back the value correctly
- exit PulseGuide
- power cycle
- select location 1 via the keypad
- shown: W 6 50 ... too bad ...

No: unfortunately, the value written by PulseGuide is _not_

properly after a power cycle if the longitude is East.
Last test I did was to set the longitude to W 6 50 then
change
the
longitude via PulseGuide to E 5 50, then click "send to

Re: Error in AP driver

Pierre Henrotay
 

John,

The sequence cannot work exaclty like this: after the power cycle,
the keypad prompts for location selection; selecting location 1 will
replace the mount values. I habe autoconnect to No and want to leave
it as is.

So I refrained from entering the location 1 and got the
initialization dialog in PulseGuide, where I selected Cancel (did so
whenever PulseGuide was started).

And indeed, the value read back by PulseGuide equals the value it
originally set (and I bet it is set internally to something strange
like W -005:50:00 !!)

Of course, next time I select the location, the value will be changed
to something that PulseGuide cannot retrieve.

So it seems (GTO3 4.12 REV L):
- AP is using 0..360 (unlike LX200)
- AP is having a problem with Gg for East longitudes (storing 355 50
instead of 354 10 for E 5 50)
- PulseGuide is using -180..180 but this leads to strange values (W -
005...); side effect unknown
- PulseGuide cannot read above 180 (and hence East longitudes from AP)
- selecting the location overides the mount value, in the format
0..360

What if you don't use the handset at all after using pulseguide, i.e.:

- set longitude via PulseGuide to E 5 50, then click "send to mount"

- observe that PulseGuide reads back the value correctly
- exit PulseGuide

Re: Error in AP driver

Need to add the following:
right after "observe that PulseGuide reads back the value correctly"
I use the keypad to
- display the longitude for location 1: it is W 6 50 (although
PulseGuide did send E 5 50)
- get the location from the mount: it displays (!!!) W -05:50:00

Hi Ray,

No: unfortunately, the value written by PulseGuide is _not_
retained
properly after a power cycle if the longitude is East.
Last test I did was to set the longitude to W 6 50 then change
the
longitude via PulseGuide to E 5 50, then click "send to mount"
button, then power cycle then select location 1 again on the
controller.
Then I inspected the longitude: back to W 6 50 - so the value
was
sent but not accepted.

I'd appreciate to have AP to check what is going on: I am now
thinking that the AP controller returns an incorrect string for
east
longitude when the Gg command is issued.

Re: foam for cases

observe_m13
 

I used very high density open cell dark grey foam. It gives but quite
reluctantly, similar to the closed cell foam. Your choice of the
closed cell polyurethane foam should be excellent as well. For cases,
I managed to scrounge an old aluminum monitor case for the 1200 ra
section and a "Scopeguard" style case built for a heavy piece of
obsolete equipment for the dec section. Keeping them as small as
possible is really important, especially for the RA section. At 50 to
55 pounds, bulking it up is counter-productive to say the least. I
would think that even a half inch thickness of good closed cell foam
would be adequate with good handling and transport techniques; and up
to an inch of foam for even better protection if one isn't quite so
careful. More foam than that would be necessary if you were building
these cases for rough handling and shipping, but every inch adds
weight and bulk. Keeping them as light and small as possible is really
important for the 1200.

Rick.

I am going to make a set of cases for my 1200 and a couple sets for
friends with 900's. My thought was to use the polyethylene foam that
they shipped with but only use 1 layer of it to save space. I will
not be shipping with it but just moving it in and out of my truck for
the occasional star party so it will not have rough handling

I got a sample of the grey firm foam like found in most equipment
cases but it seems very mushy/ soft and would compress a great deal
with the weight of the mount and I fear offer little support unless I
use several inches. The foam that it came with is just the opposite,
very firm but if AP ships with it, it must be good.

I will build the boxes using Baltic Birch plywood with a removable
lid and had thought of making it so that the interior where the mount
sits is exactly the same size as it shipped, but the box ID size using
1 less piece of the shipping foam. The Dec assembly is not that large
so original size is not a big deal, but it would be nice to reduce the
size for the RA assembly mainly.

Any thoughts or opinions from what others have done?

Thanks

Re: Broken clutch knob

Wiggins, Rick
 

Hi Pete,
I have seen the flurry of posts. Let me offer some simple
suggestions. Don't put any glue or any other stuff down in the hole.
I think that is a low probability of success and higher probability
or making the problem worse.

Next, Are you comfortable with working with the suggested tools? If
so, then take the easy-out screw extractor advice. If not, then have
someone that is comfortable with tools do this or take it to a
machine shop. Of course, you could always mail to AP for repair.

1. First take another stainless steel screw of the same size, put it
in you vise and do a test run of the set punch, drilling, and easy
out insertion. If you can do it in the vise, you can do it in the
mount.
2. If it is too hard to center the dril and not slip, then do this
setup with the drill press and light slow drilling.
3. After you are comfortable with the process, set up your mount so
that you can drill straingth down into the screw.
4. Use a set punch to provide a small starting dimple. This would be
a light tap with the hammer, so you get just a small dimple to
prevent the drill from skating across the screw surface.
5. Drill either with the drill press or very steady and carefully
straight down to make a pilot hole. Use a very small drill bit. Be
careful not to break the bit!
6. Now drill a larger hole to the correct size specified bt the
screw extractor.
7. Slowly and carefully install the easy out.
8. Slowly and steadily back out the screw extractor, making sure to
apply only perpendicular torque. Make sure the wrench is held
perpendicular to the extractor and that the extractor is parallel
with the screw. Dripping a light oil down the hole (only one drop)
may help if you are worried about the screw being struck or cross
threaded. Wait 5 minutes for the oil to soak around the threads.
9. Completely remove the broken screw.
10. Clean the hole of oil and debris.
11. Celebrate with Holiday Drink of choice!

Cheers, Rick

seem
to remember that at one point this summer I noticed the knob wasn't
square to the mount. Not looking into how it was put together, I
thought to myself "hmmmm. Interesting construction that could let

I realize now that what had probably had probably happened is the
aluminum had split but not broken right off. If I had realized the
(somewhat odd) construction of the "bolt" I would have backed it
out
and replaced it right away. Live and learn.

Thanks for all the advice. I'll let you know how it goes. I've
already
had both the Dec section and RA section back to AP at least once,
so
I'd rather avoid another repair visit. I sold my backup G11 last
week,
so it would leave me without a good mount!

All that said, I still think an easy out is the way to go.
Maybe if

Since the top of the broken stud is 3 mm down in the threaded
hole, if
glue of any sort is put on top of it and the other piece is
threaded
in, any excess glue will be forced out of the space between
the two
broken pieces and into the threads both above and below the
break,
since there will be no where else the excess can go. I
seriously
doubt that there is anything that can be done to seal the
threads
adequately to prevent this, since the glue is relatively
incompressible. If the amount of glue used is so small that
there is
no excess to squeeze out, it might work, but the proper amount
is
probably difficult to estimate.

Re: Error in AP driver

Hi Konstantin,

The value is being rejected by PulseGuide I think because the keypad wrote a
value over 180 degrees to the mount. The range is -180 to 180 in the LX200
protocol so I that is the range PulseGuide validates.

In any case if I am understanding the problem correctly the keypad firmware
is not writing the correct value when above 180 degrees anyway... or the
firmware is wrongly converting it.
