Re: New firmware, tracking rate problem w/ EXOS2

 

Well, that was exciting :-)
 
Rumors notwithstanding, I am not losing my marbles.  There is a problem scenario buried somewhere in the firmware upload process.
 
My understanding is that there are TWO ways to update PMC8 firmware with the new CM.
* Firmware tab (download, pick, flash selected), and
* Advanced tab (file pick, Upload EEPROM)
 
Here's what I tested (logs below)
 
* Boot PMC8, connect CM
* Firmware tab> download, pick, Flash, looks good, expected version reported.
* Disconnect, Boot PMC8, reconnect CM, check version... and "WES" remains !!!
* Disconnect, Boot PMC8, reconnect CM
* Advanced tab, pick file, Upload EEPROM, looks good, expected version reported
* Disconnect, Boot PMC8, reconnect CM, check version... and now I have the expected version.
 
So, for whatever reason, the first try appeared to work, but did not. I don't have the means to bracket it down further.  
 
I'll now set up a tracking test, just to confirm that I'm really rid of the problem. That was a pretty simple 'tell' last night.  After tracking for a while, park the mount.  If it's the bad version, it will be unable to find its way back to the park position marks.

Re: New firmware, tracking rate problem w/ EXOS2

 

Hmmm...
 
Thanks Mike, Wes
 
Here's the sequence:
 
Jerry announces new firmware, puts it on the forum.
* Bob downloads and installs it with the prior CM.
* PMC8 reports ES6B09T13EXOS2WES post-install with ESGv!.  
* Mount responds to basic slew-and-park indoors.
*
* Jerry annnounces that Mike found a problem with the release
* Jerry announces a revised firmware release, BUT DOES NOT CHANGE THE VERSION.
* Bob waits until Chris releases new CM
* Bob uses new CM to update the mount firmware, and tries the new default download feature.
* PMC8 reports ES6B09T13EXOS2WES post-install with ESGv!
* Mount responds to basic slew-and-park indoors.
*
  
The only option I have for checking that I have the correct version is to go back to Documents\PMC8Firmware, check dates and trust that it all worked, because the PMC8 cannot tell me itself.
 
If I open the old/Jerry's-first .eeprom with Notepad++ and search for the version string, I see "ES6B09T13EXOS2WES". 
If I do the same with the new version, I see "ES6B09T13EXOS2".
 
So... the only scenario I can think of that explains this is that:
a) Jerry's first posted firmware version, and the one that I first downloaded, was the "WES" version.
b) The new (non-WES) version was correctly downloaded by the CM
c) Something went wrong (either a user or software problem), and even though the CM reported success, the old "WES" version remained on the PMC8.
 
So, not much to do but try again and see if I get a different result.  
 
[Chris, I will remove the PMC8Firmware directory before reattempting, and take it from the top]

An equitorial mount is a beautiful thing.  It basically models the earth!  The earth rotates around it's axis.  As does the mount. 

The stars define a celestial sphere at infinity distance.  They are (essentially) stationary.  They appear to move because the earth rotates.  In fact they appear to rotate around the Earth's axis.  If we align the mount Ra axis with the earth axis then when we rotate the Ra and look through a telescope mounted on the Ra axis as we do, the stars rotate around the mount Ra axis.  

So to track a star with the telescope we just have to get the polar axis (Ra) lined up with the earth axis.  Then turn the scope in Dec and Ra until we get on an object, and then lock Dec and slowly rotate the Ra axis at the same rate the earth is turning.  The scope then follows the object as it describes its circle around the earth.

The mount has the mechanical properties needed to make this all work perfectly IF THE RA AXIS IS PARALLEL TO THE EARTH AXIS.  That is what we strive for by doing a physical polar alignment.  If successful, all we need to do is run the Ra axis at sidereal rate.

If we cannot get the mount physically aligned then rotation of the Ra axis will not compensate for the Earth's rotation...instead of moving in nice circles around our Ra axis stars will describe another path.  Thus while Ra motion is needed to follow them so too will motion in Dec be required.  If it is known how far out of alignment the Ra axis is relative to the Earth's axis, it is possible to compute the exact Ra and dec rotation needed at any time to point the telescope at a desired object.  Explorestars does those computations for you continuously but you have to tell it the alignment error.  The alignment error is what is found by doing a 2 or 3 star alignment.  

If the alignment error is zero, then there is no need to do any computations to keep an object tracked...just run Ra at the correct rate.  

So in summary...the 2 or 3 star alignment provides the information needed to compute the Ra and dec positions needed to keep a target locked in our field of view.  If the mount is physically aligned perfectly those computations are known before hand.  Thus if we can do a perfect alignment explorestars knows what to do without a 2 or 3 star alignment.   

When you reset alignment you are telling Explorestars that there is no need for extra computations.  Once you do a 2 or 3 star explorestars uses that data to do the computations.

Perhaps that helps.

Right.  In fact that version you have is not even an official release.  How in  heck did you get it? Note the subscription "Wes". That was something Jerry and I did during testing.   

As Mike said use the new cm to load the software.

Re: New explore stars app

brian skinner
 

Hi everybody, having reread the information on the ExploreStars app on the About page, it is implied that neither a 2 or 3 star alignment is required if "proper, physical" Polar alignment is achieved.
Could this be clarified please?
kind regards, Brian

There is no one star alignment.  That was refuted by Jerry in a post following when it came up.  The sync function applies when the motor counts are set equal to the RA/Dec of the mount.  It is useful in removing Ra/Dec home error after alignment.  It cannot correct for polar alignment error.

There is a new version of the Android app available on the Play store.  It is easy to load, like any other app.  The database has been updated as well.  Suggest you load the Configuration Manager with which you can load the new database into your SD card.  The CM runs on windows and thus you will need to mount your Android SD card as an external drive.

There is no update yet for anything in the windows explorestars nor for the iOS version.  

Finally there is a firmware update for the PMC8 that if you have not loaded yet you should.  This firmware is appropriate no matter what explorestars or ascom you run.  The Configuration Manager will do this for you but get where you can connect by serial first.

New firmware, tracking rate problem w/ EXOS2

 
Edited

Jerry,
 
First time out since the firmware update.  Earlier in the evening, PHD2 was working awfully hard and guiding wasn't great.  Didn't think too much about that, as there was some wind.  Got close to the meridian, parked the scope for a pause, and was surprised that the RA didn't return properly to the diamond marks when it stopped.
 
Waited out some clouds, and then slewed to the Veil.  Was surprised that Astrotortilla was not able to solve and center after that, as it's been very reliable for me.  Finally zoomed in on my target and realized that just as soon as CdC finished slewing to it, tracking would carry on past it, and quickly leave it behind.  
 
When I parked the mount at the end of the session, the DEC returned to its registration marks, but the RA was way off its marks - perhaps 60 degrees from upright at a guess.
 
Exhibits attached. 
 
Thoughts? 
 
Thx!
 
- Bob

New explore stars app

Is there a new explore stars app for PMc-8 that has the one star alignment feature now?
I have the orginal version for my Exos-100 mount. Is this new version an upgrade and advertised as such?  have to throw out the old app and re load the new one? Or is there an upgrade to be layered on top the orginal app?

Hi Chris, 

Very interested in this.  

I currently use Ascompad, and while I'm grateful it works as well as it does, there doesn't seem to be much support for it. 

And like you said, it had to be in the foreground, and I have only gotten one joystick to work though I believe you are suppose to be able to use both.

Question about Switching to Serial #iEXOS-100

Irimie Bogdan
 

So ther's the question of a newbie, but eager to learn.
New proud owner of a exos-100 and I'm  trying to make it work with asiair and I've reached the point when i have to switch it from wifi to serial. Im using the PMC8ConfigurationManager and when I'm searching for the serial port is always not found. I've used a cable usb A to usb B (mini usb) to connect the PC with the exos.
Is supposed to be like that and the com will show up after i will do the switch via telnet command or maybe i have some other issues with the cable or the exos is not working properly or other reasons.

Thanks

I have a couple of questions regarding the new features of the Explore Star App (Android):

1)      New button to display objects near where the telescope is pointed (OBS button)

Question:  Does this mean, when you are doing a star alignment and you hit the OBS button, the app will organize the available stars you are able to see in that specific area automatically?

 

Where the FOV is set in Settings:

Question:  Is the FOV button in settings depicted as “Obs Size”? The app’s default is 2…so is that a FOV of 2-degrees?

 


3) Improvement in the Alignment Routine operation.

      Question:  Does this take into consideration the elevation at a given location? 


7) The button used during alignment was changed from SYNC to ENTER to more accurately describe the function during the alignment process. When pressing ENTER during the alignment process, the data is being gathered for 2 or 3 stars and then after the final data is acquired, the mount model calculation is performed and the alignment is completed.

 

The SYNC button now only does as it is defined, see time 3 below. The SYNC is also known as a 1-star alignment and is used when you have a good to excellent physical polar alignment typically needed when doing astrophotography.

 

A few bugs were identified and corrected in combination with the firmware update:
3) The SYNC button functionality now works as designed, setting the current mount position to the target coordinates when pressed.

        Statement:  “Sync” is now 1-star alignment.  Why not replace the word “Sync” with “1SA”  (one-star alignment) in the settings/ main screen menus? 

 

Thank you in advance for your assistance regarding this matter.

Hi JR, 

Thank you for your questions.  I will try and answer them in order

 

1)      New button to display objects near where the telescope is pointed (OBS button)

Question:  Does this mean, when you are doing a star alignment and you hit the OBS button, the app will organize the available stars you are able to see in that specific area automatically?
The OBS button shows a list of the objects in the database that are within the set number of degrees, i.e. 2 degrees when set to 2 (See next question). I wouldn't say that it "organizes" it literally just lists them so that you can see what other interesting objects you might be looking for are near where you are pointed. This is really meant for when you are observing, not necessarily when doing an alignment

 

Where the FOV is set in Settings:

Question:  Is the FOV button in settings depicted as “Obs Size”? The app’s default is 2…so is that a FOV of 2-degrees?
Yes, the "Obs Size:" field on the Settings page is used ot set the FOV, 2.0 means 2-degrees as you say.

 


3) Improvement in the Alignment Routine operation.

      Question:  Does this take into consideration the elevation at a given location? 
I am not sure what you mean. If you are talking about what stars are available and are shown in the list, it only is concerned with showing everything above the local horizon. It assumes a perfectly flat horizon with no obstructions such as houses or trees. The elevation has no impact on which stars would be above an unobstructed horizon.


7) The button used during alignment was changed from SYNC to ENTER to more accurately describe the function during the alignment process. When pressing ENTER during the alignment process, the data is being gathered for 2 or 3 stars and then after the final data is acquired, the mount model calculation is performed and the alignment is completed.

3) The SYNC button functionality now works as designed, setting the current mount position to the target coordinates when pressed.

        Statement:  “Sync” is now 1-star alignment.  Why not replace the word “Sync” with “1SA”  (one-star alignment) in the settings/ main screen menus? 
The definition for setting the current motor counts to the current coordinates is "SYNC" this is what the function does. Calling it a 1-star alignment may be a simple way of looking at the function, but is a misnomer and shouldn't be used as it confusing. It is confusing because the SYNC function does not impact the alignment model as you might assume it might when using the term "1-star alignment" would. The SYNC does not have anything to do with the alignment just as when you set a clock to the proper time does not impact how much time is between the numbers 3 and 4, it's always 5 minutes between minute hand positions 3 and 4.
 

Thank you in advance for your assistance regarding this matter.

No problem, thanks for your questions.
