Roland,

Characterizing the Dec Axis Motions (09-15-03) - PDF document.
I went through the instructions. At first, I tapped on the controls
and the star almost flew off the screen. I then started to get a
better handle on how much pressure to apply and started controlling
the movement better. I'm still not sure what this test is telling me
as opposed to the PulseGuide tests. I would think the PulseGuide
tests still indicate something is wrong with the Dec axis. Here are
the results saved in the Track.log file:

Exoplanet TrES-1b in Lyra

ayiomamitis
 

Dear group,

Last night I sat down to pursue the predicted transit for TrES-1b in Lyra. Although the winds
were very strong and I did think about packing things up on more than one occasion, I
eventually sat things out and let the session complete (much to my satisfaction after seeing
the results). However, I would like to revisit this exoplanet over the next few days with the
two or three opportunities which do exist so as to pursue hopefully a cleaner result under
better conditions.

The light curve is available on my website at

http://www.perseus.gr/Astro-Photometry-TrES-1-20080708.htm ....

I promise to follow-up later this week with another transit result for TrES-1b under better
weather conditions.

Clear skies!

Anthony.

- the way controller and handpad are housed, wires attached etc. Looks a
bit like "military grade" stuff definitely designed for field use :-)

As expected, the sky clouded up and it started to rain, so I have to
postpone any field tests and any real imaging with the new scope.

Nevertheless, I am pretty proud and happy Mach-1 user.

Mount Will Not Connect To Computer -SOLVED

Bill Bradford
 

First I thank all who have responded about this problem. It was gratifying to receive so much help.

The problem apparently was a corrupted serial port driver. Why it decided to do that while I was connected to the mount and doing Move commands I have no idea.

Richard Crisp hit it on the head when he told me that I first needed to get Windows up to date on my computer. The computer has been used only for astro the past couple of years and was way out of date. I did the update today.

Second, he said that after Windows is up to date to delete the serial port in the Device Mgr. Then to reboot so the system would have to go find the drivers. He said he would lay his money on it working. I have to admit that I was skeptical. :>)

Sure enough...it worked. Thanks, Richard.

Thanks everyone,
Bill


Re: Mount Will Not Connect To Computer

Hi Bill,
My first attempt at HyperTerminal did not work out well. I'm sure that I did not do something right.

Am going to try again after I finish updating the computer. It has not been connected to the net for a long time, so am updating Windows and the latest The Sky 6 drivers.

Appreciate your input.

Regards,
Bill

Bill is it too much trouble to jumper pin 2 to pin 3 and use Hyperterm
to at least prove the computers serial port works ?

Re: Mount Will Not Connect To Computer

Bill Bradford
 

Unfortunately, your right about the lack of knowledge in electronics retailers. When I bought the cables I had to tell the clerk what a serial cable was. He thought everything was USB.

I made sure to read the package to see that it said that it was a straight through serial DB 9 cable.

I tried to connect with a different cable today and still have the same problem. I am going to try to connect on a friend's 1200 to get a final determination on the computer and cables.

If I can connect on his mount, I will give you guys a call about next steps with my Control Panel.

Thanks to you guys for the support.

Reversing cables are also often configured male to female in terms of
the plugs on each end. There is often no way to tell by looking at the
cable which type you have. That is why we ended up offering the cables
on our website. It was too difficult and confusing for customers, and
the people at the computer store frequently don't have a clue that more
than one type of cable even exists.

Hi Howard,

The cables are regular serial cables and are connected male to female.
They were not bought as a set. I used two 4 ft. cables just to get the
extra length.

But, I am going to get a single cable to replace them.

Thanks for the post.

Two reversing or null modem cables hooked together can effectively make
a single straight through cable. The cables would have only worked
when hooked together in tandem, and could not possibly work
individually. Having only one of the cables fail would then leave you
in a fatal situation. An easy test is to check continuity from each
numbered pin to its corresponding numbered hole at the other end of the
cable.

Subject: Re: [ap-gto] Mount Will Not Connect To Computer

I tried both com ports on the mount and I am using a native serial port
on my computer. I also tried to connect using another computer and had
the same error message.

My set up has two 4 ft long serial cables in series. So, tried each
cable separately to make sure that I did not have a cable failure. I
figured that it is highly unlikely for two cables to fail at the same
time.

I will be back from the dark site tonight and will call you guys
tomorrow or the next day about possible additional testing I can do. I
will do an echo test (as suggested by a group member) using Windows
HyperTerminal to totally rule out the computers and cables. Although, it
also seems unlikely that there would be a port problem on both
computers.

At the suggestion of another group member I also tried to connect using
PulseGuide vs. just The Sky. PulseGuide also gave the mount not
responding error message.

The good news is that I am better at using the hand controller now. :>)
Unlike my Tak mount, where the loss of computer control would seriously
limit my ability to get on faint targets for photography, using the AP
hand controller allowed me to image okay with just the additional time
necessary to enter RA and Dec for stars not in the controller's
catalogue. A small price for the ability to image as usual.

There are two com ports. Did you try them both? Also, do you have a
computer
with a com port or are you using a USB-serial converter? If so, you
might
check your converter. The com ports on the mount servo are quite rugged,
and it
would not be logical for both of them to fail simultaneaously, in fact
they do
not fail very often at all. However, a converter can suddenly fail
without
reason.

Re: Mount Will Not Connect To Computer

Reversing cables are also often configured male to female in terms of
the plugs on each end. There is often no way to tell by looking at the
cable which type you have. That is why we ended up offering the cables
on our website. It was too difficult and confusing for customers, and
the people at the computer store frequently don't have a clue that more
than one type of cable even exists.

Hi Howard,

The cables are regular serial cables and are connected male to female.
They were not bought as a set. I used two 4 ft. cables just to get the
extra length.

But, I am going to get a single cable to replace them.

Thanks for the post.

Two reversing or null modem cables hooked together can effectively make
a single straight through cable. The cables would have only worked
when hooked together in tandem, and could not possibly work
individually. Having only one of the cables fail would then leave you
in a fatal situation. An easy test is to check continuity from each
numbered pin to its corresponding numbered hole at the other end of the
cable.

Re: Mount Will Not Connect To Computer

Thanks, Marj.

I have the two 4 ft. cables because my other choice was a single 25 foot cable. I bought them just before leaving to go imaging, so took what I could get at the time. But, that was several imaging sessions ago and I should have replaced them by now and will do so.

However, they have been working fine during multiple imaging sessions. I also tried them individually and still have the problem.

Thanks for the information.

Those batteries don't last very long. What you need is a big marine battery

from one of the big box stores. Cost is around $45 to $65, so it's not
expensive. Reason why it seems to stall when using Dec is that RA is always
powered,
running the mount in sidereal mode. When you add Dec, you are increasing
the
current draw because now both axes are drawing power. This may put it above
the
threshhold of the battery, where it then begins to die.

AP 900 GTO CP3 Dec Motor Stall and Worm Gear Adjustment?

Hank Sielski
 

Hi Howard,

I just got back from the Golden State Star Party and had a couple of great
nights with my AP155 EDFS and the AP900 GTO CP3 (no 594 from early 2006). I
finally managed to see all the Messier and Caldwell objects (and a bunch of
other stuff) around Sagittarius and Scorpio, but I had a slight problem with
a stall in the Dec motor at the end of each night.

After about 4 or 5 hours of observing and slewing around, the Dec motor
stalled and the yellow light came on. I'm thinking that this may be due to
my battery voltage getting low (I have one of the little Kendrick batteries
that you used to sell) possibly combined with a slight "tightness" on the
worm gear mesh (since it always seems to be the Dec axis, and you recall I
had a slight problem with this a couple of months ago).

Until recently, I've never had a problem going even a couple of nights with
this little battery (I don't image or use a dew heater), but I'm thinking
that after 2 plus years it may be getting a bit tired and it might be a good
idea to replace/augment this battery with some kind of heavy duty marine/AGM
battery with more capacity. Do you have any recommendations here?

On the worm gear adjustments, I went to the web site and it seems that I
can't see where Wally may have updated the 900 instructions for the newer
motor brackets/configurations yet. Do have a link to them or do you think
it would be OK to use the ones for the 1200 in the mean time?

Thanks for the great products and support!

Hank in Sunnyvale

Last night I had connected my Mach1 (new...have had it for 6 weeks) to The
Sky, as I usually do, and was testing the connection by using the Move
command in The Sky and everything was doing fine.

However, after a minute or so of moving each mount axis, the mount would no
longer take any command to move it. I removed power from the mount for 15
secs or so and tried to connect through The Sky and got an error message
saying that the AP GoTo was not responding.
There are two com ports. Did you try them both? Also, do you have a computer
with a com port or are you using a USB-serial converter? If so, you might
check your converter. The com ports on the mount servo are quite rugged, and it
would not be logical for both of them to fail simultaneaously, in fact they do
not fail very often at all. However, a converter can suddenly fail without
reason.

Re: Mount Will Not Connect To Computer

I tried both com ports on the mount and I am using a native serial port on my computer. I also tried to connect using another computer and had the same error message.

My set up has two 4 ft long serial cables in series. So, tried each cable separately to make sure that I did not have a cable failure. I figured that it is highly unlikely for two cables to fail at the same time.

I will be back from the dark site tonight and will call you guys tomorrow or the next day about possible additional testing I can do. I will do an echo test (as suggested by a group member) using Windows HyperTerminal to totally rule out the computers and cables. Although, it also seems unlikely that there would be a port problem on both computers.

At the suggestion of another group member I also tried to connect using PulseGuide vs. just The Sky. PulseGuide also gave the mount not responding error message.

The good news is that I am better at using the hand controller now. :>) Unlike my Tak mount, where the loss of computer control would seriously limit my ability to get on faint targets for photography, using the AP hand controller allowed me to image okay with just the additional time necessary to enter RA and Dec for stars not in the controller's catalogue. A small price for the ability to image as usual.

Thanks! I think I'll try upgrading my battery before I start messing with
the worm gear adjustment. Do you think 35AH is big enough (just mount, no
camera/dew heater)?
35AH will give you about 35 hours of tracking and slewing.

After about 4 or 5 hours of observing and slewing around, the Dec motor
stalled and the yellow light came on. I'm thinking that this may be due to
my battery voltage getting low (I have one of the little Kendrick batteries
that you used to sell) possibly combined with a slight "tightness" on the
worm gear mesh (since it always seems to be the Dec axis, and you recall I
had a slight problem with this a couple of months ago).
Those batteries don't last very long. What you need is a big marine battery
from one of the big box stores. Cost is around $45 to $65, so it's not
expensive. Reason why it seems to stall when using Dec is that RA is always powered,
running the mount in sidereal mode. When you add Dec, you are increasing the
current draw because now both axes are drawing power. This may put it above the
threshhold of the battery, where it then begins to die.

If there is another AP mount in your area, you might try to see if your
computer will talk to it.
