2 star alignment doesn't work

G-man
 

I did setup the mount, polar scope aligned to polaris, leveled, adjusted all the axis etc, but when I tell it to do a 2 star alignment from a perfectly aligned position, it asks for a star but it slews to some random piece of sky, nowhere near where the star is supposed to be. Yes, I load the GPS coordinates. Any help why this doesn't work?

Thanks.

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.

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.

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

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

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.

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.

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.

Now that I think about for the moon pic I used a 2.5x Barlow. 
Whatever you decide balancing your scope is paramount. 
If you are not balanced the mount will not behave well.

i have the Exos-2 and an Explore Scientific Carbon Fiber 8” Newtonian with a Nikon DSLR and guide scope and it works just fine.  I have attached some pics of my setup for your reference. Also I have attched some examples of my images I obtained with the setup, so you can see the magnification.  If you are looking for a wider field then you should consider a 6” Newtonian.

Scope Recommendations for EXOS2

Karl
 

I just got an EXOS2 PMC-Eight for Christmas, and license from my wife to spend another $500 to beef up my OTA.  I'm coming from a 130SLT.  I want larger aperture for optical viewing, but I also want something I can use for astrophotography as well.  I've read countless threads on the topic in general, but now I'm hoping for some mount-specific advice.

I think I could stretch my budget and go for the Explore Scientific Carbon Fiber 8" Newtonian: https://explorescientificusa.com/collections/newtonians/products/208mm-newtonian-f-3-9-with-carbon-fiber-tube .  But is this too much weight once I add a webcam or digital SLR?  Seems like a 6" OTA would be safer, but that doesn't seem like enough of a jump from the 5"  already have.  Anyone have any experience using this OTA or any other 8" Newtonian for astrophotography with the EXOS2? 

Or any other alternatives to recommend?  I'm on the fence about the lower focal ratio, and have also been considering this OTA: https://www.bhphotovideo.com/c/product/1444466-REG/meade_217022_lx85_200mm_f_5_newtonian.html.  It's listed at 18lbs, which is the same as the Explore Scientific Carbon Fiber, but I can't find any other information about it, and I'm not sure I can trust the listing.  

Thanks,
Karl

Hi Jerry

For me, it's essential to be able to connect the mount via TeamViewer from one laptop to another.
I see the advantage of a quick Ad Hoc connection in the field, but I only use my setup at home, and can't use TeamViewer to connect between my laptop's because of that.

I have my camera and OHYCCD Polemaster connected to my laptop nearby my mount in my garden and it would be nice to be able to control this laptop from inside my house, we have a very stable internet connection 100/100 MB so that would not be a problem, and in the same time to be able to connect to the internet.

Right now I have to use a USB hub with the camera and Polemaster connected and a 10 m USB cable from the garden to my laptop inside the house. It works but I would like to have this connection made wireless. BTW I only use my setup for astrophotography.

Karl es@ has a point and a much better explanation on why the wireless connection would be preferable for some of us.

Best regards
Palle


Re: WiFi AdHoc mode change

I just got the EXOS 2 GT version of this mount and am still figuring out my workflow, but because this was one the first questions on my mind, I just thought I'd add my two cents.  For me the advantages to having the PMC-Eight connect to an existing ssid have nothing to do with opening the equipment up for internet access, but rather are:

1)  Not having to disconnect whatever I'm using to control the mount from the Internet (my wifi is pretty solid throughout the backyard).  It's frustrating to have to switch my laptop or tablet back and forth between ssids to check email or run a search.
2)  A better couch astronomy experience, since my connection distance won't be limited by the transmission power of the PMC-Eight module.  Of course, if I'm already putting an AIS out there to run the camera, it's easy enough to control the PMC-Eight via a cable using the AIS.  But then again, it'd be nice to have one less cable to worry about, and not to have to worry about switching between serial and wifi control on nights when I want to forego the AIS for optical viewing. 

Of course, the mount's probably infrequent excursions beyond the backyard will be problematic.  But the problem is relatively easy to solve if I run a hot spot on my phone with the same ssid. 

Actually, with my old mount, I was running Indi on a Raspberry Pi unit.  Not sure whether I'll try to replicate that experience with the PMC-Eight, but I mention it because I had the Pi set to automatically switch to a hot spot after a certain amount of time if it couldn't connect to my ssid.  Something like that would seem ideal for the PMC-Eight--set it to auto-connect to a ssid if possible, but fallback to ad-hoc if it can't connect.
