ipad doesn't seem to control the pmc-8 #EXOS2

Phil Bondurant
 

I successfully updated the firmware and can operate the mount from my MS Surface.  I tried my ipad for the first time, but could not seem to get it to control the mount.  I connect the wifi and the app runs but it won't operate the mount.  It seems that it should just work.  I poked around trying to some hints, but didn't find anything?

Any ideas?
thanks
Phil

Hi Wes 

Im running 20A01.03

Another question is. 

When tracking is turned off in the mount panel. Can the mount be still be guided with only the guiding camera via asiair?

Thanks Wes.

Not sure what is you issue but for sure .01 is not good, use .02 or .03.

locked Tracking and guiding issues on asiar pro

Leandro Gonzalez
 

Was able to connect my iexos-100 to asiar pro but Im currently having problems tracking and guiding the mount via a zwo guide cam and guide scope.

It looks like im able to track in the 0-1 range for a few seconds but it then the graph spike +8 range.

I noticed the that resetting tracking on the mount panel in asiair menu resets the tracking and i can re gain guiding. But this lasts for a few seconds again...

I believe im running 20A01.01.eeprom version. 

Any other users with this issue?

Thanks a lot in advance!

Leandro.

Really liking the Asiair

In English (Google Translate)
Can ExploreStars establish a serial connection to IEXOS-100?
So according to the manual you can make the operation wired when Ascom is installed and the connection is then made via a Serial/USB to Mini-USB cable. But I haven't tried it myself yet, since I don't have the cable here yet, I have other beginner problems;-)

ExploreStars is WiFi (wireless) only. 

Thanks Roland!

Re: Can ExploreStars connect to IEXOS-100 via serial? #ExploreStars

Chris Hanson
 

Thank you Keith for the well-articulated need for ExploreStars wired.  I have similar issues.  I run the PMC-8 wired 100% of the time driven by NINA.  I have used NINA wireless before but I am always concerned about dropping connectivity at the outreach site so I just use wired.

 

Thanks,

 

Chris Hanson

Jerry,

 

I would also like to see ExploreStars work wired. If at all possible.

 

I have always for a while now used my EXOS PMC-8 wired.  But a couple of weeks ago I volunteered to do outreach at the Woodruff Boys Scouts weekly for their Astronomy Merit Badges.

 

But I could not make the wifi connection to my ipad stay connected.  I changed wifi channels and it would work for ten minutes and then drop.  And after regaining wifi connection, ExploreStars will not connect.  But my ipad says it is connected to the PMC-8 network.  

 

I had to stop using the EXOS Mount wirelessly.  

 

Now the EXOS mount is just a visual demonstration of what an equatorial mount looks like and I use my roommates C-8 on the SE mount.

 

I could use the EXOS with Cartes du Ciel.  But I have found the goto to only be accurate with a good polar alignment.  And the kids can only stay a short time after it gets dark for about 30-40 minutes.  Sunset is around 8:47 and twilight is about an hour later.  So I do not have much time for the kids after dark.   

 

So to have the ExploreStars to work wired would be huge for me doing outreach.

 

Another feature that would be great is to have a search function like EQMOD has.  You do not know how many times I have had an object just outside the visual field of view.  And the search in eqmod will start a search that gets bigger and within a second or two the object enters the field of view.  This would really help when using the C-8 on the EXOS.  Just a thought, every telescope mount should have this function.

 

Thanks

Also lt. Handbuch kann man den Betrieb kabelgebunden machen, wenn Ascom installiert wird und der Anschluß erfolgt dann über ein Serial/USB auf Mini-USB-Kabel. Hab's aber selbst noch nicht probiert, da ich das Kabel noch nicht hier hab, hab andere Anfängerprobleme;-)

Re: 2/3 Star Alignment, possible to select the stars to align? #alignment #ExploreStars

Wes Mcdonald
 

Euan

No worries.  

During the alignment process of 2 or 3 stars after centering use the enter button.  Once alignment is complete you can use the sync button after a goto once that desired object is centered up.

There are mount parameters that the 2/3 star alignment does not resolve.  In particular cone angle error and dec home position error.  When you do a sync on an object (after completing the virtual alignment done with the 2/3 star process) these errors are effectively removed.  This will improve the accuracy of the subsequent gotos.   Unfortunately, the further out of mechanical alignment your mount is in general, the sync correction applied will be more or less effective as you move out away from the place in the sky where you did the sync.  The way to think of this is that when you sync on, for example, a star in Orion, a goto to the Horsehead nebula, also in Orion should be very good.  But a goto for example to the pleiades may not be as good.  But a sync on a star there should make gotos to a star in Taurus be very close.

Using sync on a bright star that is easily found and identified visually is a great way to get deep space objects into your eyepiece/camera field of view.  Instead of doing a goto to the iris nebula for example which you would be unable to see with the naked eye to find it in a red dot finder, do a goto to a bright star nearby.  Center up that one and sync, then do a goto to iris.  Should be bang on.

hehe,

I feel like a school boy learning here.

So once I have the alignment star in centre, the enter button is pressed.  

Then after a goto on a chosen object to image. The object is then centred and then press sync?

Almost

The ENTER key is the key that tells the alignment process that you have centered the object.  Sync is only used (in Android and iPad versions) after a routine goto and centering to coordinate all the motor counts to the object ra dec.  During alignment only use the enter button.

Somewhere in there after you pick the object for the alignment you have to press the goto button if the auto alignment is off.  Did you did that?

Hi Wes

Thanks for the help, I have installed the ExploreStars App on an android tablet, the version i have installed is ES1.9.20051.494 DBVer2.3 FWVer 2.03.

Just to confirm the steps for the 2/3 Star alignment process this is what I am doing using the Android version above;

  1. Menu > Settings >  Set Auto Align to off
  2. click 2 Star Alignment (this takes me back to the main screen)
  3. Menu > Catalogue > Select first star to align (for example Vega), This brings up a screen with the star details. Click Sew to object. This brings up the main screen. 
  4. centre the star on the eyepiece/camera by using the Up/Down/Left/Right buttons
  5. What does the "Enter" button do here??
  6. Once the star is centred click on Sync
  7. Align the 2nd star by the same process in steps 3 - 6.
  8. Mount should now be aligned, so use catalogue to goto an object. The letter P in a tringle should be shown to indicate that the alignment data is being used.

Can you confirm that this is the correct procedure. 

Thanks.

Good image and great detail.

What region of London? 

I bought my 152ED APO from Explore Scientific because many years ago I looked through the 6-inch Cooke Refractor at Hampstead Heath Observatory in Northern London. A 6-inch refractor has been one of my dream scopes. The 14SCT is the other.
