Re: Erratic Movement in Dec slewing

jerk is still here after doing all checks that includes making sure
the backlash on the keypad was set at "0". If you have a mount

You probably need to add some dec backlash adjustment. Read that
section in the keypad manual.

Hi Mike,

Since you have an SCT, could the visual shake when you move in DEC
be mirror flop? Since RA slow motion is always one way, you
wouldn't see any in RA. A 14 inch mirror has a lot of inertia.

I have a large refractor on my 1200 and have never seen any shake
like you describe.

Re: Strange Declination Behavior

twade35
 

Mark,

After manually moving it across the meridian, I would first sync it
using Pinpoint in MaximDL. Then I would immediately click the
Recalibration button in TheSky. After "Recalibrating", I would then
attempt to slew to the correct imaging location which would result in
the Dec going the wrong way. I have to admit, that while clicking the
Recalibration button in TheSky nothing seemed to happen so perhaps it
isn't. I didn't use any other software or the keypad for Recalibration.

I used MaximDL for the Goto slew. Perhaps, it was still confused
(i.e. didn't recognize the Recalibrate command from TheSky. I have
MaximDL connected through TheSky.

Is there a way in TheSky to "Goto" specific coordinates (i.e. manual
entry of RA and Dec)?

Thanks,

Wade

Hi Richard, No orthogonal issues, I have had my dream machine when imaging this does cause somewhat of an out of balance on the east side. When I slew on "1" setting to center the image on the camera chip the image jerks only in the N/S direction. I have my weight shaft measured so I know where to place the weights.This works great.- Mike

AP900 GTO PSU - revisit

Philip Perkins <ppml2@...>
 

Folks,

May I briefly revisit PSUs for my AP900 GTO? For the past 9 years I have been powering the mount with a 12v 3.3A PSU (ex HP Omnibook) and generally the mount has worked fine, including when loaded with the RCOS 12.5". But just recently I noticed that the control box LED usually shows orange, whereas I assume it is supposed to show green. Also, very occasionally, the hand controller resets (reverts to starting menu) during an imaging session, though the mount carries on tracking perfectly. So I think it's time to investigate a more beefy PSU...

I am considering a high quality 6A PSU from Maplins (sold as a laptop PSU) which provides 7 selectable output voltages including 15v, 16v, and 18v. I have read that the mount will run on anything between 12v and 18v. Is this true and if so is it better to use the highest voltage available (18v) or should I back down a little?

The spec says that the PSU is fully stabilised with low ripple and low interference and has overload and short circuit protection. Info is here: http://www.maplin.co.uk/module.aspx?ModuleNo=43515&doy=17m6#overview
The only potential issue (for outdoor use) are the air vents whereas my existing PSU is fully enclosed. Should I go for an enclosed model if possible?

Also can someone help identify which controller I have? ( which GTOCPx) Although I bought the mount in 1999 the control box developed a problem and was (very kindly) replaced by Roland in 2003. So I suspect it's either CP2 or CP3.

Many thanks

Re: [SPAM]RE: Keyspan USB Server

It appeared to me as if they added the battery, and then only partially
updated the website. The opening paragraphs tout the battery, and then
later text tells you that you need a power source. I imagine a call to
their tech support people is in order. This might also be a good
evaluation of the level of support that is available - another important
consideration for such electronic goodies!

Hi George,

That looks like an interesting device. The Serial portion requires
power, as I read it. It appears to have an internal rechargeable
battery, and can also be powered by an external "cube transformer" or
from a powered #9 pin on the serial device. We do not provide power to
the number 9 pin of the RS232 ports on the GTOCPx control boxes. Since
they seem to advocate using a power source rather than depending on the
battery, you might want to consider fashioning a cable to tap into the 6
volt receptacle that we provide on the control box for the Pentax 6x7
cameras. Our receptacle is for a 3.5 mm phone plug - center is
positive. Their plug specs are on their website.

I do not know whether you can make it all work, but I'll be interested
to hear. I wish I could give you a more definite answer.

The Keyspan device is great for the observatory and handling several

We have not tested the USB Server as thoroughly as we would like to, but
were confident enough to go ahead and start offering it. Our main
concern arises when using the USB Server with the USB to Serial adapters
if everything is fully loaded. There are potential issues that stem
from the fact that serial communicates in a way that is different from
USB, which in turn communicates in a way that is different from
Ethernet. Think of the old party game of "whispers" or "I've got a
secret" where a secret message gets passed around the room via whispers
and then the original message is compared to what the last person heard,
and everyone supposedly gets amused by how the message was corrupted.

where everyone speaks a different language. This, in effect, is what
the system I demonstrated at NEAF is doing, and so far, it has worked
remarkably well for us, even on a machine running Vista.

Although we had all four ports of the USB to 4-port Serial adapter going
at once, we did not have the remaining three USB ports of the USB server
simultaneously in use at NEAF. We were also using very smartly written
software - PulseGuide and TheSky - both of which handle their serial
communications in an intelligent way that doesn't overload the COM
ports. Finally, I have not tested other serial based software like
focusers, rotators or dew heater controllers, nor have I had additional
USB ports occupied with cameras or other devices while simultaneously
giving the serial ports a workout. I am very confident that the USB
server will work extremely well to communicate with USB devices. That
was its intended purpose, and I'm sure it will handle four USB devices
at once with flying colors. It was not, however, designed to be a
bridge from Ethernet to Serial, even though we are having some success
using it in that manner by combining the USB server with the USB to
serial adapters. The real test will be for people like you to get
these products out in the field and get them working under real
observatory situations with a variety of equipment.

Just a couple more points:

1. I am most certainly NOT trying to dissuade anyone from trying the
USB Server as a remote solution. If we did not feel that it could be
used successfully, we would not be offering it. I did, however, want
to be honest about potential limitations and about the "unknowns" that
still exist. Between my busy schedule and the never ending rain here
in the Midwest, I also don't know how or when I'll get more testing
done, especially real life testing under the stars.

2. We will also be offering two more products from Keyspan when I get
them evaluated a bit further: Another USB server that is USB2.0 for
higher speed applications like cameras, but has two ports instead of
four, and then the Mini-port Replicator that was mentioned by Dale Ghent
in an earlier set of posts (21986)

3. Contrary to several earlier posts, the Keyspan units DO NOT use the
Prolific chip sets that tend to be so problem prone. They use chipsets
from Texas Instruments that have the added advantage of containing
re-programmable ROM. This allows the Keyspan USB to Serial adapters to
be fully updated instead of only updated with band-aids to the drivers
on board the computer. Permit me to repeat: Keyspan USB to Serial
Adapters DO NOT use Prolific chip sets!

4. In addition to the Keyspan units, we have started selling straight
through serial cables to eliminate the hassle of trying to find them in
the stores. They are 15 feet in length, and really truly are
straight-through!

Howard, if you're monitoring this group - when I saw you at NEAF you
were experimenting with the Keyspan USB server (I think it was their
product US-4A). Have you got any progress to report? Seemed very
promising for remotely running the mount, camera, etc..

Re: SPAM message from Howard - is it real ??

Woodwind
 

Can anyone confirm that a message purporting to be from Howard and titled

" Re: SPAM Re Ap-gto Howard "

is real ? The problem is that it appears with a date or time tag which is ahead of the real time - a fairly sure sign that it is a fake message.

Thank you, Howard and Konstantin. Yes, I am interested in the combo solely
for star parties to eliminate the risk of tripping on wires to the public.
Howard, your powering suggestion is a good one. I wonder how long the
internal battery lasts without recharging.they imply elsewhere that the unit
draws an insignificant amount of power.

Thank you,

George

Hi George,

That looks like an interesting device. The Serial portion requires
power, as I read it. It appears to have an internal rechargeable
battery, and can also be powered by an external "cube transformer" or
from a powered #9 pin on the serial device. We do not provide power to
the number 9 pin of the RS232 ports on the GTOCPx control boxes. Since
they seem to advocate using a power source rather than depending on the
battery, you might want to consider fashioning a cable to tap into the 6
volt receptacle that we provide on the control box for the Pentax 6x7
cameras. Our receptacle is for a 3.5 mm phone plug - center is
positive. Their plug specs are on their website.

I do not know whether you can make it all work, but I'll be interested
to hear. I wish I could give you a more definite answer.

The Keyspan device is great for the observatory and handling several
serial

eliminate wires that the crowds trip over in the dark. Would the blue

We have not tested the USB Server as thoroughly as we would like to, but
were confident enough to go ahead and start offering it. Our main
concern arises when using the USB Server with the USB to Serial adapters
if everything is fully loaded. There are potential issues that stem
from the fact that serial communicates in a way that is different from
USB, which in turn communicates in a way that is different from
Ethernet. Think of the old party game of "whispers" or "I've got a

Hello George,

I have the older AirCalble Module without a battery. It works fine
with different units. I have driven my AP Mount with a Palm and my
Mac. It is good if you just want to use a planetarium program. If you
are imaging there is no need for cause you have more cables anyway.

were experimenting with the Keyspan USB server (I think it was their
product US-4A). Have you got any progress to report? Seemed very
promising for remotely running the mount, camera, etc..
thanks,
