locked What Is Your Experience Level With GOTO Mounts? #poll

Jerry Hubbell - Explore Scientific VP Engineering
 
Edited

Since we are a growing forum with several people joining lately every week with our new iEXOS 100 PMC-Eight mount system available, I wanted to get a feel for the level of experience our customers bring to the table. This will help me to understand if our level of documentation and support is sufficient to help our new customers have a great initial experience with our mounts. Please select one from the answers below.

Re: Scope Recommendations for EXOS2

 

James,

Gosh!  That's quite a load!  I see a camera on the 4-inch, and what looks like a guidescope near the newt's focuser.  Mixed use visual/astrophoto?
How's the photo side working for you with all that weight?

Re: 2 star alignment doesn't work

Hi Robert,

Thanks for your input on this problem, this is the first I have heard of this problem and its relation to the Android version of ExploreStars.  I will check this out with my Android tablet to see if I can repeat it also. If Guillermo is using the Android app then that would be good to know also.

Thanks

Re: 2 star alignment doesn't work

I have randomly experienced this as well.  I bet you're running Android version of Explore Stars App, right?  I do this:

Level and polar align Mount.

Affix telescope.  Balance  Check if I'm still polar aligned after the jostling.

Release clutches and set to the park position aligning the arrows on the mounts RA and DEC axes.

Look again after the jostling.

Plug in PMC 8

Wait a minute. 

Set tablet to connect to PMC 8 WIFI.

Open Explore Stars.

LOAD GPS

Confirm correct lat and long for my location.

Confirm Mount set to "EXOS II"

RESET ALIGNMENT

Confirm alignment data at 0's

Then I commence the two or three star alignment.

If it slews to a random part of the sky, I use the "PARK" button to return to home position.  "STOP ALIGNMENT" "RESET ALIGNMENT" Confirm 0"s. Try again.

It seems to take a couple of tries every time I set up for it to just start working.  Probably user error (I'm a rank noob). 

If the gurus have any pointers or see obvious flaws in my process I'd love guidance and/or correction. Hope this helps.

Yes, I load the GPS coordinates. Any help why this doesn't work?

Re: 2 star alignment doesn't work

Hi Guillermo,

There are a couple things you should check to make sure they are correct in addition to the longitude and latitude. The longitude must be a negative value if it is WEST longitude, i.e., -77.7106 for my location in Virginia. Also the time must be set to within a few seconds with the proper time zone set on the computer. for every minute the clock is off, the scope will point 1/4 degree off in Right Ascension.

Please check those items.

I would also suggest that you clear the alignment and with your good physical polar alignment slew to a bright object such as a bright star and let me know how far off it is in your finder.

Thanks

Have my Exos 2 PMC8 matched up with a Bresser 8 inch Newtonian with a First Light 4 inch refractor.



Just under the recommended weight limit of the mount.

Thanks Robert
I'll try that, as soon as possible.

Wishing you all a Happy New Year.

I am using the ES 152mm Mak-Cass First light scope. So far GREAT configuration.


Re: Surface 3 Crashing with Explorestars

Jerry Hubbell - Explore Scientific VP Engineering
 

Hi Jerry,

I assume you have installed the database file and you don't get the DATA FILES MISSING message, nor the PLEASE WAIT message when it is not connected to the mount. As the installation program has not changed for a while an others have installed it recently and have not had issues, I think we can assume that the issue may be with your Windows version on your Surface 3. The only thing I can suggest, assuming that you did not remove the database file when you uninstalled and reinstalled the ExploreStars application, is to go ahead and uninstall the ExploreStars application again and then delete the ExploreStars folder and SQLite file from the Pictures directory, reboot and then reinstall again from scratch.

That's all I can suggest write now.

Surface 3 Crashing with Explorestars

shredderf16
 

Jerry,
    I've got the Exos2 with PMC8.  I installed Explorestars on my Surface 3 with Windows 10.  Running the program I can do all the normal things except a 2 or 3 star alignment.  Everytime I push the 2 or 3 star alignment buttons the app crashes very shortly thereafter.  If I do the alignment tour it will work.  I've uninstalled and reinstalled the app, it still does the same thing.  I haven't yet tried it with a laptop or phone to figure out if it's the Surface tablet.  
Thanks,
Jerry Barth

Re: WiFi AdHoc mode change

 

Chris Moses built a small program to simplify the switch, if that helps you.  I haven't tried it, but it's down in the Files User Contributions subdirectory.

Re: WiFi AdHoc mode change

Hi Bob.

Didn't see your post until now.

Your right, the winter is coming and wow it would be nice to sit comfortably in the couch and having the mount and camera spinning on the back porch.

Like you I don't use my setup for visual use, only for astrophotography,
As Jennifer also mentioned, next step for me is to find a USB-serial cable and then figuring out how to get through the code shifting from wifi to serial connection.
Thanks Bob.

garciasampedrogj@... Exactly!


Re: WiFi AdHoc mode change

G-man
 

Having the mount communicate over a WLAN IP (non AdHoc) could mean not having any hardware sitting outside.


Re: WiFi AdHoc mode change

thilqvist@...
 

Hi Jennifer

Thanks.. That's exactly what I'll have to do, but then again, there is the coding for switching from wifi to Serial connection.
http://hosted.comm100.com/KnowledgeBase/PMC-Eight-Application-Note--AN002-How-To-Configure-and-Switch-Between-the-WiFi-and-Serial-Connections_A5000038.aspx?id=5000038&siteid=56501

it could just as well have been in the Russian language!
But anyway I have to try to figure out how to do it.
Thanks again.

Best regards

Re: WiFi AdHoc mode change

 

Palle, Karl,
 
I've had my EXOS2/PMC8 for about a year now.  One thing that gelled early was the control approach for the mount, and it's worked well for me.  Here's a bit on my arrangement, FWIW:
 
I use it exclusively for astrophotography (no visual), and I wanted to support two use cases:  Back yard within wifi range, and standalone offsite.
 
Basically, what that meant is that the mount/scope/camera had to be able to operate in fully self-contained fashion with no regular internet access, and then also accept an inbound remote desktop connection when at home with wifi available.  Winter is coming... :-)  
 
I use ASCOM exclusively and POTH is my ASCOM server.  ASCOM requires Windows, so I purchased a small refurb laptop (an x230) to manage the mount/guidescope/camera.  They all connect directly to the laptop via USB cables.  I currently have enough ports and do not need a hub, but may do that at some point in the future.  My first use for that guidescope was strictly Sharpcap polar alignment, but I've moved along and now it's guiding as well.
 
I connect to the scope's laptop in the back yard, from my regular laptop indoors via TightVNC and the house wifi, rather than Teamviewer.  I did look at Teamviewer and passed, but that's some months ago and the reasons for that are getting hazy.  Doesn't matter a lot - TightVNC works fine for me. 
 
While I do see the benefit of connecting the PMC8 to its control program by wireless for an Explorestars/tablet visual user, I saw no benefit to that for the astrophotography use case.  
 
For that scenario, I required a  time-sensitive dialog to run smoothly between my ASCOM hub (on Windows), the PMC-8 box, PHD2 and the guidescope, and BackYard Nikon.  I couldn't see a reason to leave myself open to the risk of latency or dropped packets with wifi, either in ad-hoc or infrastructure mode.   If have a remote (TightVNC) connection into the scope laptop, the scope laptop is still doing all the work, the command/control traffic is all still local to its hardware.  It's simply sharing its desktop over wifi, so I can watch from inside.  
 
I alway connect my PMC-8 to the scope's laptop via USB cable, and this arrangement has worked well for me.  
 
Hope this helps...
 
- Bob

I use Team Viewer at home with my Exos-2 mount with no problem.
You need to connect the mount to a laptop via a wired connection with the PMC-8 Helper script. Then connect Team Viewer via the wireless internet connection with another laptop.
