Re: Trouble Loading New CP4 Firmware

Martin Artem <martin.artem14@...>
 

Good afternoon,

I also did never ever update my GTOCP4 software version since the day I did get it (it did have the version VCP4-P01-00) during the update did have some issues to get a valid IP ADDRESS while connected via
the network Cable, did never have any issues to get an IP ADDRESS via WLAN, after switching off and on and unplugging the network cable and plugging it again, did suddenly get a valid IP ADDRESS shown on the BLUE SCREEN or the UPDATE PAGE of my GTOCP4..

Now to my question, I was able to upgrade the software from VCP4-P01-00 to VCP4-P01-10.. but have troubles to load the file WiFi_A402.wif..

Do I have to update also the file WiFi_A402.wif ? since my GTOCP4 does not want to do that, hence did just give up.. and if YES, is there any other way to do hat ?

Thank you

Martin

Hi Howard,


I can confirm that I also have firmware version VCP4-P01-00. The CP4 serial number is 0112.
I don't have TeamViewer installed but can certainly do so if you decide that it would be helpful.

Thanks and regards,
John

Okay.

The documentation for APCC states that support for getting barometric pressure from a weather station is planned.  Is there a list of stations that will be supported, and an estimated time frame for this support?

Re: PECPrep for Mach1

Roland Christen
 

I would not try to put a new curve into the mount memory at this point when the mount is new. Use the one that was recorded at the factory for at least the first 6 months before trying to modify it or change it. I have seen too many times that users generate bogus PE curves that makes things worse. If you are guiding you really won't affect the results much even if you don't turn on the PE correction.

Hi.  I am a very excited new owner of my first AP mount (Mach1).  I want to use PECPrep to do PE correction but don't know all the specs to use. 
It wants to know the following:

  1. Steps per full rotation
  2. Total Gear Teeth - refers to the RA worm gear
  3. Worm Period (S)

Does anyone know these values?

Re: APPM error

Roland Christen
 


A tugging cable on your setup would probably be the equivalent to a multi-ton load on the Hale scope. :-)
And here is an interesting experiment I did recently. I set up an 1100 encoder mount with a 130 scope on it. The Renishaw absolute encoder coupled to the CP4 will try to keep the telescope axis to within 0.2 arc seconds of the commanded position, so any outside influence is instantly countered by the control loop. Pushing on the back of the scope causes the drive motors to "push back" against the outside force. I could see this while observing an artificial star with a high power crosshair eyepiece inserted in the camera's off-axis guider. While there was some flex of the telescope tube inside the felt lined rings, amounting to 3 to 5 arc sec, there was no movement of the star when I pushed on the cradle plate which is rigidly attached to the telescope axis. However, when I pushed on the camera, I saw movement of 20 to 30 arc seconds. After tightening down the focuser drawtube, this was reduced considerably, however not fully eliminated. So, we have a number of things in any setup that can produce subtle errors of pointing and tracking no matter how well we establish a model.

If you can't go at least a couple minutes unguided then your setup has a bad model, unmodeled flexure, or too much random error. There's nothing that modeling software can do to fix the last item. To get better performance with modeling software you may need to invest some time figuring out why some areas of the sky are not as accurate as others and fix the mechanical issues in those areas.

As for a 530 ton telescope, the modeling is going to be much more deterministic and repeatable because the weight of the instrument allows it to be impervious to outside factors. A tugging cable on your setup would probably be the equivalent to a multi-ton load on the Hale scope. :-)

Re: APPM error

 The matter I was addressing was that I don't see that APPM's sky model has improved my guiding.  Maybe it has, but it's not very visible in the numbers I see as the corrections roll by.
My guiding with the 17" astrograph can vary enormously depending on seeing. I've had guiding values of less than 0.1 arc sec RMS and as much as 0.5 RMS on a different night. Star sizes vary from 0.9 arc sec FWHM on the very best night to 3.5 arc sec FWHM on the worst nights. And none of this has anything to do with the sky model.

Re: APPM error

There is another plane that has not been discussed, it is verticality the error of which will increase with altitude.  Simply stated check the level of the mount.  Ray's program is gang busters.  So is TSX Tpoint.  If you are on a portable mount Tpoint will get you in the neighbood faster.

Re: PECPrep for Mach1

W Hilmo
 

I believe that a PEMPro license is included with the AP1100 and AP1600 (and it used to be included with the AP900 and AP1200), but I don’t think that it was ever included with the Mach1.

 

For what it’s worth, I have been a PEMPro user for a long time (even before I got my first Astro-Physics mount).  It is very good at what it does and, to me at least, is worth its price.

To clarify:  The Mach1 does come with PEMPro-generated PE correction already loaded into the CP4.

Unlike the larger, more expensive A-P mounts, it does not come with a copy of PEMPro.

Tom,

When you say "you won't have to
buy anything" does that mean that
PEMPro V3 is free (beyond the trial)?
Or did you mean I wouldn't need to buy
anything except PEMPro?
PEMPro is not free, but during the trial you could create a PEC curve for your mount. You would not have to buy anything extra to trial PEMPro if you can use PHD2.
