PoleMaster - results

email@...
 

Ok, I've tried PoleMaster 4 times now with my AP900. I have the camera mounted on the dovetail of my Planewave scope as I've previously explained. It is very easy and quick to use. However, I'm disappointed in the results. Everything I've heard says it's possible to get within 30" of alignment. I've used PEMPro to measure my results. At best I'm getting an error of 7' in RA and 12' in dec. This is not very good. If I was off by 2' or 3', I'd say I just needed to be more careful, but this error tells me something is wrong. I used my RAPAS which normally gives me an error of about 3' (yes I should calibrate it better), then let PoleMaster tell me to move it way off this point. 


The procedure is so simple that I don't see how I could have messed it up this bad. I really think there is an error in the PoleMaster software (version 1.3.0). Maybe it's not correctly figuring out the displacement of Polaris. The procedure is so fool proof it should give better results. All I really know is that I can't get anywhere near the accuracy I've heard others get. 30" might be a dream but it seems like the procedure should easily get me with 2' or so.


I guess spending more time with PEMPro is my only option for improving polar alignment. I'm really eager to hear well PoleMaster works as more people try it out. Surely I'm not the only one having problems with it.

AP-1600 Fuse

BigE Astro
 

Hello folks,


Quick Question,


I am installing a fuse to the power supply for my AP-1600.  My observatory is solar powered with two golf cart batteries running the scope, focuser, camera, and cool down fans as well as my flat panel.  Dew zappers and computer on AC circuit.  I belive everything is well grounded. 


What size fuse should I install in the positive line going to the telescope.  5 amps? or a little less like 4 amps.  I know this may be redundant but I figures I would fuse things to death.


One other thing I have been wondering.  Why no power switch on the controller?


Thanks.

Hi Rolando,

many thanks for your quick responce!

As everything should work in my observatory via CCD Autopilot in the future, i must control the mount with Sky X.

I read your perfect explanation several times, i try to repeat the necessary details for controlling the mount with Sky X to see if i get it.

1) Set keypad to Autostart = EXT.
2) Always initialize the mount with Sky X
3)
Park the mount always from computer

The procedure to get back the position of the scope is clear.

I will drive up to my observatory when the weather becomes better and try to fix everything, i let you know.

Thanks and kind regards,

Wolfgang

Hello Wolfgang,
 
This is very common occurrence when you mix startup and park positions between two programs. You are using the  keypad program to start the mount (makes no difference if Autostart Yes or No), but then you try to park the mount using another program, the SkyX. The problem is that the clock times of the keypad and the clock time of the SkyX are slightly different.
 
Since Park1 is right at the meridian, starting with one program and parking with another can easily cause the mount to park on the other side of the meridian, with the scope on the east side. This is because of the small time difference of the keypad clock and your computer clock. The mount CP3 controller determines which side to flip the scope to depending on the time, and even a few seconds is all it takes to flip the mount to the other side of the meridian.
 
If you must control the mount using SKY X, then always initialize the mount with that program. Set your keypad to Autostart = EXT. Initialize the mount from your computer and park your mount always from your computer. Then you will not send wrong time instructions to the mount for starting and parking the mount, and the scope will always be on the correct side when pointing to a celestial object.
 
If you always want to initialize and park the mount with the keypad, then set your keypad to Autostart = YES. No need ever to set it to NO because your setup is permanent. Then always park the mount using the keypad park positions, or simply place the scope where you want it via the direction keys and turn off the power. Either way, with Autostart = YES, the mount will always know where it is because it uses its own keypad time to calculate the position of the scope. This is very robust and will never fail.
 
Now to fix your scope position. To get your scope started properly when you have lost the mount pointing, simply follow these simple steps (remove external programs, they can be used later):
 
1) Set the keypad to Autostart = YES
2) Loosen all clutches and hang onto the scope.
3) With the keypad in Setup/Park, send the scope to Park3
4) When the mount has stopped slewing, place the scope in approximately Park3 position
5) Tighten all clutches again
 
Now your scope is back to being where it should be. You can verify the other two park positions, Park2, and then Park1. With the mount in Park1, you can use a bubble level on the two axes to determine if you are accurate, or you can send the mount to a known star, center it in your crosshairs and use the RECAL button to fix your position accurately.
 
Now you have a choice, will you be using the keypad always to park the mount correctly in Park1? If so, leave it in Autostart = YES. You can park the mount with the SKY X, BUT you will have no control over which side the Sky X will choose, East or West. If the clock on your computer is just a few seconds faster than the clock in the keypad, The Sky X will choose the East side. Even if you do that, next time you start the mount with Autostart = YES, the mount servo will forgive you and always go to any celestial object properly.
 
Will you instead want to park the mount correctly always with The Sky X? Then you must always initialize it always with this program. Therefore you must set the keypad to Autostart = EXT. You still can park the mount with the keypad, but you will have no control over what side the mount parks on in Park1.
 
In either case, under no circumstances should you set the keypad to Autostart = NO in your setup. That is ONLY for first time setups in a new location with new scope and unknown mount positions.
 
I hope that the above is clear.
 
Rolando

Hi to all,


i am new here in this group, my name is Wolfgang and i live in

My AP1200 GTO CP3 is permant mounted in my roll-off roof observatory. In
January i changed from Sky 6 to Sky X as i prepare everything for remote
imaging.


Since a few days nothing works like it should....when i park the mount
(Park 1) via Sky X the OTA is in the East side and not like it should be
in the West. The room for the mount and scope (12" f/4 Newt) was build
for parking the OTA in the West.
In Sky X i use the Setup for AP mounts. I also used the Ascom Setup and
i updated the Ascom Astro Physics V2 driver but the OTA is still parking
in the East.
I have been setting the Autostart feature of the AP1200 to “No” and used
the keypad for initialization but i got the same troubles again, OTA in
the East.
So I set the keypad to "EXT" and restart the mount. Resuming from Park
in Sky X, the map shows the scope in the park position but when i try a
go-to it takes off in a totally inappropriate direction. The mount has
no idea where it is pointed.


I never had this troubles before with Sky 6.....


Does anybody else have troubles like this? Hope i get some help.....

Re: SkyX parking bug

chris maier
 

I have noticed this, but didn't understand why it slewed twice to park. I got used to it. The second slew was always a small move. Thanks so much for bringing this to SB's attention.


SkyX parking bug

 

Some of you may have noticed some odd behavior when parking your mount with the SkyX.

 

First, SkyX will send the mount to its saved park position that you had created in SkyX. Then, it issues the ASCOM park call which will send it to the park position that you defined in the V2 driver. So, your mount will slew twice in order to park. This can be quite disconcerting since these positions may not be the same and it may head in an unexpected direction.

Re: Is there "Backlash control" in the current CP3?

These settings are not recommended to be used when autoguiding. They were originally meant for manual guiding with crosshair eyepiece. Those days are pretty much gone forever. Set all backlash to zero for autoguiding.

Chris,
    That may be true, but in case of some emergency, rather than being without a CP4 while it is either acting up – as firmware sometimes does – or it is out for repair, the user doesn’t really need to turn PEM on, when switching temporarily to the backup CP3. After 9 years, I have yet to use the PEM, since the mount quality itself is so good to begin with. Besides, there will always be cases when a controller shows a “suspectedly” odd behaviour, and it would be nice to switch back, to older firmware/hardware, to compare results.
 
    That being said, leaving the “Servo Box Adapter” on the AP-900/1200 RA axis, and adding a Velco strip on top, provides a convenient “shelf” for the Keypad, which would be much better than using its flimsy hanger “hook”. The shelf may also be a good spot for a USB hub or a PowerWrx DC junction box, to handle all the telescope accessories that require it.
 
    Finally, the two CP3 lock down screw holes, at the front of the adapter, which held the CP3, could be used for a nylon cable grip, to hold the Y-cable going toward the CP4’s new pier mounted position.

You can certainly use the adapter in any way you wish.

 

Incidentally, we have a short lanyard available for the keypad, if you need one. It attaches to the integral hook. Quite convenient for hanging anywhere you  like.

    As I read through the Upgrade Instructions, I wonder why it requires the existing “Servo Box Adapter” on the AP-900/1200 RA axis, to be completely discarded – it doesn’t mention it being moved to the pier.

 

    Surely, if as recommended that the user keeps his existing CP3, for emergencies, that adapter should remain on the axis to switch to the old CP3, and the new CP4 cable clip could just as easily by screwed onto the adapter.

 

    Perhaps there is a missing step in the PDF.

Chris,
    That may be true, but in case of some emergency, rather than being without a CP4 while it is either acting up – as firmware sometimes does – or it is out for repair, the user doesn’t really need to turn PEM on, when switching temporarily to the backup CP3. After 9 years, I have yet to use the PEM, since the mount quality itself is so good to begin with. Besides, there will always be cases when a controller shows a “suspectedly” odd behaviour, and it would be nice to switch back, to older firmware/hardware, to compare results.
 
    That being said, leaving the “Servo Box Adapter” on the AP-900/1200 RA axis, and adding a Velco strip on top, provides a convenient “shelf” for the Keypad, which would be much better than using its flimsy hanger “hook”. The shelf may also be a good spot for a USB hub or a PowerWrx DC junction box, to handle all the telescope accessories that require it.
 
    Finally, the two CP3 lock down screw holes, at the front of the adapter, which held the CP3, could be used for a nylon cable grip, to hold the Y-cable going toward the CP4’s new pier mounted position.

Ray,

 

Forget the previous email, I just opened the Setup Telescope dialog under the AP folder and it gave me the information I needed. Seems I have v5.07.02 installed both at home and at SRO. Sorry for the noise.

Ray,

 

This may have been asked and I missed it but did any of the previous drivers require an un-install before installing the newer, like v5.08.04. I can’t tell which version I have installed when I open the driver it blinks to inform me of the new drive and doesn’t display the installed version.

 

Thanks,

 

Steve

Subject: [ap-ug] New AP V2 ASCOM Driver Release v5.08.07

 

 

Hi all,

I have a new release version (this is not a beta) of the driver available
for download. I think this version should solve the recent issues with the
changing longitude E/W value. Also, this version has been run through the
ASCOM driver validation test and has passed. There are some other minor
fixes for issues found, including some related to the upcoming CP4, so this
version is mandatory if you plan to upgrade to the CP4 when it becomes
available.

Changes include:
- BUG FIX - Completely reworked site Latitude/Longitude Save/Restore
- BUG FIX - ASCOM RightAscensionRate and DeclinationRate were not being
enabled for GTOCP4
- BUG FIX - Show Virtual Handbox by default was not working correctly
- BUG FIX - Fixed a few minor ASCOM conformance issues
- IMPORTANT NOTE: this Build was checked and passes all ASCOM Conformance
tests with no Issues or Errors.

**************
IMPORTANT: if you are upgrading from version v5.08.01 or earlier you must
uninstall the earlier driver first from Control Panel. This is required
because the location of the driver and supporting applications has changed
so as not to potentially interfere with other ASCOM drivers.

Re: Installation instructions - CBAPT for pier mounted CP4

I think there wouldn't be a problem going back and forth, as long as you knew that PEM data would have to be re-recorded on whichever box was currently being used.  And that when swapping boxes the current box won't know where the previous box had parked the mount.
 
Frankly it has been my experience that the CP3 controller is so blasted reliable that I can't imagine needing a spare.  And if the CP4 is as reliable as we all expect it will be, a spare CP3 or CP4 really isn't going to be much of an issue either.
 
And I certainly won't be going back and forth between the two boxes on a regular basis.
