How many pins are actually used on the DB9 connector on the 1200 goto?

I'm going to make an extension cable and need to know how many

conductors to get.

I noticeed quite few of members of the group with c-14 on GOTO 1200

mount. I want to mount old (1986) Rolands F/8 refractor on top of C-14

using Ken Dauzat rings,I would like to share experince with someone

who has tried this combination in past. I just received new mount 8

weeks ago. I plan to use in in subzero winter weather in the

observatory. Any fear of oxidation of metallic bearings etc. or damge

to motors or electronics if left out side in the observatory for

prolonged periods? Thanks for the input. Mahesh Yadav

#1702 Dec 23, 2000

According to my copy of the A-P Mafia Code Book (published in 1999), no one

is allowed to place non A-P OTAs atop A-P GTO mounts (sec. IV, subparagraph

2). The Code also states that the punishment for disobeying this rule is

swift and severe. ~8^)

We and several of our customers have 1200 mounts in remote operated

observatories that are exposed to the full range of temperatures and

conditions. No problem. Roland does advise if you are putting the 1200

into a permanent installation that you lightly oil the mating aluminum

surfaces so they don't stick together from the inevitable minor

corrosion.

In what way are you having trouble with the tracking, PEC and Goto? The new

chip does not change these functions. Are you properly polar aligned? If not,

you will not track accurately in RA or Dec, and your Goto accuracy will be

poor. PEC will also not correct RA drift due to poor polar alignment.

Roland:

I have the mounting very well polar aligned, I have it permanently

mounted on a pier at the observatory. Also the OTA is orthogonal with

mounting axes. Several months ago, I wrote Marjorie explaining her

what my problem is, but gladly I will explain it again.

1.- When you try to track a Star using sidereal speed, the star keeps

wandering my reticule center (My scope has a 5000 focal lenght), so

with the 12.5 mm. reticule we are taking about 400X, it shows a

periodic error plus the Star drifts slowly away.

2.- When I try to train manually the Pec at this power, the trained

tracking is worse than with the PEC off, I have retrained it many

times but with no correction, I have even tried an St-4 guider for

training, I have trained my 12"LX200 with it and it tracks very good.

3.- When I image planets at the prime focus (5000mm), I use an HX516

ccd camera. I have used the solar tracking speed, though the sidereal

speed works better. When you center the image, the planet starts

drifting right and left (periodic error) until finally the planet

slowly drifts away after 15 to 20 minutes. I have tried the PEC but

it tracks worse, so I am sticking to the sidereal tracking speed.

I also have the Digital Voice and works very good, but not the

tracking.

4.- When I use the Go-to function, I put a 45mm or 50mm eyepiece to

get around 100X to 111X and a wider field of view. I put the clock on

time and because the mount is permanently fixed, I just go to a Star

(not Planet or the Moon) and make a recalibration, just check that

the telescope was not moved since parked, I do another goto to a near

object, usually is in the field, then I center it and hit the

recalibrate button, then the object begins to move very slowly if I

keep the button on, so what I do is just hit rapidly the recalibrate

function and then the Menu.

Then if I go to another object, most of the time I will not find it

in the field.

Marjorie told me thatt he new chip would fix my problem, so that is

why I found this e-group web and wrote you.

My mounting has the electronics on top of the R.A. axis with the

plugs facing south, I think the new model looks up.

So as you see I have some problems with my mount, hope you can help

me fix them.

I send my best regards,

Eric Roel. > [Non-text portions of this message have been removed]

Roland:

I forgot to tell you that in #4.-, when I do the first or subsequent

recalibrations, if I keep the button on the object it moves step-like

and very slowly. When imaging the Moon, the tracking error is much

worse than with Planets and Stars, even using Lunar tracking speed,

actually it looks like there is no difference using any of the

available tracking speeds. I use 600 for slewing, that way the motors

do not wear too much, aside of that the mount is free, the dampers

are well tightened as not to stop the axes but just enough to have a

nice soft feel. I always do a drift align every month or so, so I can

tell you that the mount is well polar aligned.

In the same observatory I have a 12"LX200 and one of your 6"

f/12 "Superplanetary" triplet refractors, mounted on an HGM-200

equiped with the "Gemini" goto system, both telescopes can track

incredibly well, even that the LX200 has toy electric motors (tough I

did make the axes orthogonal using a laser, changed the declination

teflon bearings for needle bearings, took out the image shift using

bearings and taking the mirror flop out), the Gemini tracks like

anything I have ever seen, it keeps the object for hours without

drifting at all, before the Gemini installation it step-tracked. That

is why I expect much more from your flagship mount, now I just use it

for Moon and Planetary imaging using sub second integrations due to

the poor tracking. Hope this helps to see what is wrong.

Ok, after reading your other two emails, I believe you have trouble with the

tracking, pec and goto. But you give me no information to make an accurate

diagnosis of your problems. Obviously, if all our mounts had this trouble, we

would not sell any. On one hand, I can probably explain everything you see on

improper setup, without blaming the mount at all, which would maybe not be

correct. I am not there, so I cannot check things out for you. You will have

to be my eyes and ears, and tell me what you see based on waht I tell you in

this Email and following ones.



1. It is easy and tempting to explain all faults by saying something is wrong

with the chip. That may or may not be the case. As an example, in an

automobile, there is a chip that controls a lot of functions. Let's say the

car runs rough and also won't go straight down the road, instead keeps

heading for the ditch. A good mechanic would check out the spark plugs and

wires, and also the wheel alignment, tire pressure, and perhaps ask if the

driver really had his hands on the wheel while driving. So, for now, lets

forget about changing the chip, and try to weed out the herrings from the

mackerel.



2. The mount won't rack the Moon. Well, I would expect that. The Moon does

not have one tracking rate, neither does it track parallel to the earth. I

have done a lot of lunar photography, and can tell you that you cannot track

the Moon accurately with any kind of mount without changing the altitude and

azimuth alignment. The Moon is a special case, that is not adequately covered

in any book that I know of. It would seem that one could dial in a lunar

rate, and the Moon would stay still in the eyepiece. At low power, yes. At

high power, not at all. The Moon's distance from the earth varies from day to

day, so the rate at which it moves from east to west varies also. There is no

one lunar rate. The Moon also moves up and down in its orbit, sometimes beign

high in the sky, other times being very low. The Moon's orbit is not parallel

to the earth, so simple polar alignment will not follow the Moon's motion.

There will always be declination drift, as the Moon moves between its

northern and southern nodes. If you want the Moon to stay still at high

powers, you will have to radically change both the elevation of your polar

axis, and the azimuth angle. Otherwise, it will slowly drift away in your CCD

camera field. I do this whenever I want to precision high resolution

photography of the Lunar surface. One would think that the dec drift could be

counteracted by following it with the dec motor. This is difficult to do

smoothly because there is a limit to how slowly a servo motor can be run

before it becomes almost stepper like in its action. The drift in Dec and RA

is many times slower than the sidereal rate ( varying between 3 to 20 times

slower), that no single motor circuit can be built to smoothly and accurately

follow this motion, and also slew at 1200 times sidereal. The mount would

have to have 2 sets of motors, one for slewing, and one for very slow

motions. This means 4 gears etc.



So, at this point, I say that the Moon is a special case, a red herring, so

to speak, that is not the fault of the mount, no matter how much you like it

to be.



3. Slow RA drift. In 99% of the cases where a mount will not follow the stars

for a period of time, the person did not polar align it properly. Do you

understand that this can be the case? In fact, one way TO polar align a mount

is to monitor the RA drift over time, and correct the altitude angle of the

polar axis. Did you do this to the 1200 mount? The mount cannot do this by

itself, it is somethign the user must do. Please do not rely on the Polar

routine in the keypad, it is only approximate. At the powers you are using

your telescope, you must drift align. Did you drift align the Polar axis?



4. Slow Dec drift. Same thing applies here. A slow dec drift is always caused

by the azimuth axis being aimed wrong. The dec axis will not "drift" due to

faulty motors or chips, the motors are not turning in the dec axis, unless

you want to go somewhere else.



5. The GOTO does not accurately place the object in the field of view. If the

mount is not polar aligned, I would expect exactly that. Also, what affects

GOTO accuracy on a German mount is the degree to which your telescope is

orthogonal to the polar axis.



6. The PEC will not "fix" the star drift. If the mount is not properly polar

aligned, I would expect that too. PEC is not intended to fix drift due to

polar misalignment. It is ONLY intended to counter the slow periodic back and

forth motion due to worm gear error. Do you understand why this is so, and

why you cannot use PEC to "fix" polar misalignment drift?



If we can agree on the above, an it makes sense to you, we can proceed to

what could perhaps be possible problems with the mounting.



7. Let us assume that you have polar aligned the mount properly, but the

mount will not track a star for more than a few minutes. Now we need to see

whether the motor is actually turning. Using the crosshairs of a reticle

eyepiece, can you determine the drift rate? Is it 15 arc seconds per second?

If so, the RA motor is totally stopped. You can see for yourself very quickly

by removing the motor gear cover (the one with 6 small screws) and see if the

motor shaft is turning. Is the motor shaft turning?



Perhaps the motor is turning, but doing so in an erratic manner. This can be

caused by the worm gear being jammed into the worm wheel. Although we do

everything possible to adjust the worm mesh, do to shipping mishandling we

cannot always guarantee that the worm will not be forced into tight mesh

because of some heavy blow the package received while being dropped out of

the airplane onto the tarmack below. How do you check this? It is exceeasy.

There is one gear in the motor gear train that is attached by a screw. Remove

the screw, and pull the gear out. Now the motor runs free without any load.

Now you can also check the worm pressure with your own fingers. Simply turn

the little spur gear that is attached to the end of the qworm. Does it move

smoothly, or do you need an Olympic wrestler or long crow bar to turn it? If

it does not turn freely and smoothly, there you have your problem of the

erratic motion. To fix it, you simply have to adjust the worm tension. But

before you do that, you need to answer all the above questions so I can get a

better idea of where your mount might be at fault.



8. There is a very slight chance that the drive rate of the mount is not

correct due to a faulty motor drive circuit, but this is highly unlikely. If

it is, there are a few things you can do in the control box to trace this

down, but I would rather rule out all mechanical things first.



I hope this gives you enough information to start your analysis. Please check

these things out, and if you have any questions, do not hesitate to write to

me.

O.K.Roland:

I will go step by step per your instructions. I do not blame the

chip, but actually the 1200 mount looks so impressive and rugged,

that I never even thought of a mechanical problem concerning the RA

gears. I will open the gear case to find out if it has a hard spot,

on the other mounts I have found those problems and fixed them qquite

easely.

As for the Moon, yes I know of the difficulties in tracking that

object due to the inherent movements an specially the declination

drift, but what I meant is that it was worse than the normal scenario.

I drift align using the normal procedure and sometimes the one Chuck

Vaughn uses, with a Star 20. N of the equator. After careful

aligning

using a 9mm or a 12.5 reticule eyepiece with sometimes a barlow, I

can wait for up to one to three hours and then check if the Star

still is in the E-W reticule line, then I assume it is well polar

aligned. I have never aligned the mount with the Hand Pad, what I

have done is to advance the time to get an orthogonal check with the

OTA on both sides of the meridian, so I know my telescope is as near

perfect as possible in orthogonalism.

I also know that the PEC just corrects the periodic error in the RA

gears, that is why I mentioned a "Right to Left" oscillation in the E-

W axis, I don.t expect to correct declinatio drift nor polar

misalignment.

I do not know if it is normal that when recalibrating and keeping the

button on, the mount moves very slowly and in step like manner in RA,

so please let me know.

I really want to thank you for your support and help, next weekend I

will try to give more details to you.

Sincerily,

Eric.

I don't know what you mean by keeping the button on. Are you depressing the E

or W button in 1x? in .5x? or in .25x? or 12x? or what? In any case, pressing

the E-W buttons should cause the star to move smoothly east or west at the

guiding rates. If you do not depress the button, does the mount track the

star at all? Or is there a jerky back and forth motion?

Roland:

Sometimes the lenguage barrier betrays me and have trouble trying to

explain what I want. Well what I meant is that when you goto an

object and it is not in the center of the field, then after centering

it with the hand pad (E-W-N-S keys), you press #9 key in the Menu or

the menu key to recalibrate to the new position due to the centering

of the object, but if you keep the #9 key pressed, then the object

starts moving in a jerky motion as you say, getting out of the center

position. My question was if that is normal and if I just have to hit

#9 key once, or there is something wrong in my procedure.

This weekend I will go to the observatory to check the RA gear play,

my polar alignment and if there is something else that I could check

please let me know, the observatory is about 80 miles from home, so

it is a 2 hour drive, that is why I would appreciate if there is

something more mechanical or electronic to check while being there.

Receive my best regards,

Eric. >

You only press the #9 key once, quickly. This sends a message to the servo to

update the position of the object. Keeping the button depressed will continue

to send updates at a rate of 3 or 4 per second. Each time you send an

update, the servo microprocessor has to interrupt the normal driving routines

and do an extensive calculation for the update co-ordinates. It is no wonder

then that the drive will look somewhat jerky. Please push the button once,

quickly and be done with it. This Recal really does not need to be done all

the time anyway.

Eric, I just caught the last bit of your tracking problem. You may want to

look at a write-up on my web site on the use of artificial stars to assess

tracking issues. While the description uses a STV, you could use your

guider but will have to plot the data manually. The address is

www.fatbulldog.com/gdo/index.html and then go to "helpful material".

Good luck.

Roland:

Went to the observatory, took the cover of the gear train and moved

the worm gear, it is fairly loose, but the gears held with the screw

looked a little tight, so I did put some Lithium grease on the small

gears mounted on the lower part of the big gear (they were dry), put

everything back together and incredibly, the mount started tracking

very very well, I kept the Venus crescent with 416X for a long time,

just the periodic error showed, looks like probably the gear train

was tight or crooked.

The alignment is as good as I can get it, I rechecked it with drift

align.

Looks like I just have 2 problems left:

1.-When you just press quickly the #9 button (RECALIBRATE), the

object starts moving slowly out of the field, it does not matter if

you press it just once quickly or keep it pressed, the object keeps

moving out of the field.

2.-The PEC does not correct the periodic error, I trained it several

times (Trained and checked, then train again and rechecked), it has

less periodic error with the PEC OFF than with the PEC-PLAY.

I also rebalanced the OTA, it was ok, so that was not the problem

either, the GoTo function worked well, Venus was on the finder almost

at the center but not in the field of a 26mm Plossl that gives 192X

with the 5 meter 10" Maksutov, probably the "recalibrate key" moved

the last object I viewed before parking the mount.I found Venus at

around 12 O.Clock saturday and sunday too.

My handpad shows "VERSION-2.4", I do not know if I need some upgrades

or the new chip.

I would like your comments concerning issues #1 and #2.

I send Regards to you and Marjorie.

I have asked Marj to send you a new chip to be installed in your servo box.

It sounds like there is a software problem in your chip.

Your keypad version is not at fault. Soon you will be able to upload version

3 with some advanced features.

Roland:

I want to thank you for your prompt answer and your support, I feel

relieved with your comments because I thought I was doing something

wrong, or that my alignment was off, even after 20 or more years

doing drift alignments, homemade mounts etc..., Roland you made me

doubt.

I hope that Marjorie could send a new chip with instructions on how

to install it, via Federal Express or UPS, just tell me how much will

it be, so to send a check or a credit card number.

Marjorie:

Thanks, the chip will be my birthday present(April 15th),hope it gets

soon, really it is my best present. Sure I will try the chip and new

handpad version as a beta tester, glad to. Last weekend I was

observing with my old 6" f/12 "Superplanetary" refractor, it performs

beautifully, no chromatism whatsoever.

#3532 Sep 18, 2001

I want to thank Roland and Marj for the free upgrade. All went well and the process was easy.



I have a question about using the newest version of The Sky V. 5.00.014 with my 1200 GTO.



This question pertains to using the software and the mount remotely, ie. in my office in my house 100 ft from my observatory:



With Version 5.00.012, When you used the motion controls in the sky to move the scope in order to find a guide star, this would change the tracking rate of the mount so that when you did an autoguide calibration, the guide star would fall off the chip. I had to use the terminal command and type in the following :RG2# so the mount would be in the correct tracking rate.



Has this been fixed in the new 5.00.014 version?



Thanks



Joe

If you click on the Guide mode and move at this rate, then you will be at the

1x rate. If you move at a faster rate, then you will be at the faster rate

when you calibrate. Therefore, change to Guide, and make a small move, and

you will be ok.

Yes, the tracking rate in version 5.00.014 is 1x (:RG2). No need to

use terminal mode anymore, but very resourceful of you to have done

so before.

BTW thanks for you help with tracking.



I went out and set the DEC backlash to zero, calibrated my autoguider at

1x, then switched to 0.5x to track and it worked GREAT!!!!

I thought if a rate faster then 1x was selected the autoguider port

would still use 1x for corrections. The autoguider port will only

use .5x or .25x if that has been selected at the hand controller or

PC software. When calibration is performed it is done through the

autoguider port.

Sounds good. By the way, here is what Tony Hallas said recently about

tracking while taking some new astrophotos:



"last nights images should be interesting....I had the STV guiding at 1

second

intervals with an aggressivenes factor of .3 so it would not chase the

seeing"



As you can tell, trying to chase seeing is a waste of time. Advanced

astrophotographers want the mount to only guide out the slow drift in RA and

DEC.



Later today I will be posting some images I took last week at my badly light

polluted site next to the AP factory. These images shows what can be coaxed

out of the sky using modern CCD technology and only a 10" aperture. They are

not the best that can be achieved by any means but I don't have access to

pristine clear dark skies. Nevertheless, this shows what can be done and

should give encouragement to people who live in urban areas and would like to

do imaging.

That's the way it should be, but unfortunately, the drives will go at the

last selected speed up to 64x when driven by the autoguider port.

#8441 Aug 28, 2003

Dear friends,



I wonder whether AP is still accepting new purchase order of AP 1200

Goto Mount.



I ask this, because I faxed the order form to AP on August 22nd 2003

for AP 1200 Goto mount (to-be-revised version, I hope, in view of the

long waiting time) with Polar scope set, and I ticked the check box

that I would pay half of the deposit if the products are out of

stock. However, I received no confirmation of any e-mail or fax. I

then sent an e-mail to AP through its order e-mail address on Augsut

25th 2003 but again no confirmation reply is received up to now.



I do not know whether it is the usual practice for AP's customers to

wait for some uncertain period before confirmation would be received

that they are put into the waiting list.



I shall be grateful if AP owners could share their experiences of

previous purchases of AP mounts.



Thanks in advance



Raymond TSE, August 29th 2003

#8442 Aug 28, 2003

Raymund,



You can't order this mount over the counter. You have to first place your

name on the notification list at the Astrophysics website

(www.astro-physics.com/webdate/notify.html). This will place you in line

with other who are waiting for the next production run. During the next

production run, AP will start contacting people in the list. When you

receive notification, it is then that you can order the mount and maybe

wait for a few months to a year to get your mount. BTW, the line is QUITE

LONG!



Regards,



Chris

Dear Chris,



Thanks for the info. I have been put onto the Notification List.



Perhaps I do not find any caution wordings in the order form to the

effect that one should not fax the order form unless and until after

notification from AP is received.



I shall wait then.



Raymond

Raymund,



Just go to the Astrophysics Website and everything is explained

there. Production with AP has gotten a little faster lately. I think you

might be forntunate enough to be on the next run.



Regards,



Crhis

Hi Raymond:

Your fax will probably be answered soon, but it wouldn't hurt to send

another fax (or better yet, telephone if possible) asking if they received

the first one. From my experience with our home fax machine, we often

receive orders from strangers to companies we never heard of on our fax

machine. We try to inform the senders that their fax got to our number by

mistake, but sometimes we can't identify them. Anyway, it's possible that

your fax went astray.

As far as experience in waiting --- yes there is a waiting period. For me it

was about 12 months but that was several years ago. But it's worth it!

1. I recently upgraded a AP1200 to keypad 4.12 -- this routine is very

nice, with

a set of checklists, etc. While firmware updates on some devices can require

some "crossed fingers" - this goes very easily. Good job to the AP

programmers.

(It was easy before, and now it is even easier).



2. I have a AP1200 GOTO available on Astromart, or E-mail me directly.

I know this group isn't really for advertising, but just a heads up.





Thanks

I was able to get up and ut to observe this morning.The view of

Jupiter was amazingly good given its altitude. I was able to get a

nice image using the AP 1200 GOTO with a little help from my TEC 200

F/8 Flourite @ F/40. I will upload an image just FYI.

Very nice Jim!



What camera did you use?



How many sub-frames?

Thanks Mark! I use a Skynyx color camera for the planets (Skynyx

mono0 for the moon). I was shooting at 28 frames per second and was

able to stack 3700 frames. UI think I need to decrease the red color

channel just a touch on the Lucam recorder software. I think the

seeing has the potential of being very good here on this barrier

island. I hiope all is well with you.
