Re: PCM Eight connection still fails over WiFi #EXOS2 #pmc-eight #TECHNICAL #ExploreStars

I think I found the problem.
Using the .bat file provided in this thread: https://espmc-eight.groups.io/g/MOUNTS/topic/dhcp_static_ip_issue_with/77617950 does NOT work for me.
Everything seems to be set correctly when looking at IP addresses and so forth, but somewhere something is wrong.
When I change the network settings through the settings of the ethernet adapter (see image), then ExploreStars comes to life ! And I have no clue why ;/


I have tried to fire up ExploreStars 3 times from scratch, and each time I saw no trouble..
I will keep monitoring the situation and keep you posted.

It appears the iEXOS watchdog is disabled.  Always was it seems.

Paul:

Suggest you determine what wifi channel you are operating on.  Also what the WiFi environment looks like around your place.  In my view you should use your dongle to change the wifi channel to one of either 1,6,or 11.  

Get you an app on your PC or cell phone that will scan the WiFi environment and report out what is going on.    Then report back.

Wes.

Hi All, this is my first real attempt at astrophotography, using the EXOS-2 PMC-Eight Mount I recently bought, which after a few initial glitches seems to now be working quite well. it's of the Orion Nebula. I'm completely new to this so I just shot 14 Lights and 5 Darks, 30 secs each at 1600 ISO, with no guiding, on an old Nikon 3200 DSLR through a Skywatcher 200DPS Newtonian. Processed with DeepskyTracker and GIMP.

Hi guys,

I also wanted to share my photo of Pleiades, captured a few days ago during my holidays in Greece. I love the iexos 100, a portable, easy to handle, and to setup mount. Not much can go wrong! It was also very easy and convenient to transport it from Germany to Greece. 

Anyway I hope you like the result.

you haven't yet downloaded the Explore Stars App database to your computer
Chuck,

Thanks for your answer, but you didn't read the opening post correctly.
The Explorestars application AND it's database are correctly installed on this computer. The database zip has been extracted to my Pictures folder and I have had it working (inside the house) a while ago.
I went outside, setup the mount and telescope, and once outside it stopped working. Couldn't get a connection anymore.
Now, it doesn't work inside either.

Tried everything.
But the main thing is, if it should work again at some point in time, for whatever reason, how reliable of a system is it ? Next time I go out again, it may or may NOT work.. for whatever reason ... I'm rather fed up with it :(

Thanks,
Paul

Paul, you will get this "PLEASE WAIT" message if you haven't yet downloaded the Explore Stars App database to your computer. Here's the link: https://explorescientificusa.com/pages/microsoft-windows-10-explorestars-app-download . Once you're at that page, click on "Microsoft Windows 10 ExploreStars App Database Download". The data will begin to download. Follow the instructions under "Note 2", then reload the Explore Stars application and give it a few minutes to complete the download. If that doesn't bring up the compass rose, then come back here for more suggestions.

PCM Eight connection still fails over WiFi #EXOS2 #pmc-eight #TECHNICAL #ExploreStars

Paul Meesters
 

Hi Guys,

I have the PMC-Eight now almost 2 months, and still have to get my first session under the stars.

I still have problems connecting the laptop with explore stars to the PMC-Eight.
It has been discussed (as hijack in another thread), but it still does not work, and I'm getting a bit tired about it.
Someone suggested to use a wired connection in stead of wifi, but I think wifi still SHOULD work. (cable is on order)

Since my windows laptop suffered the DHCP bug, I used the .bat file to assign a static ip-address.
The PMC-Eight is the *only* SSID configured in the laptop to connect automatically. It does not connect automatic, I have to press the connect button for that to happen.

Once connected, ExploreStars (which is installed correctly, with the databases. I have seen it working earlier), remains in the "PLEASE WAIT" status, and won't do anything.



Should I throw the mount in the trash, take the 700 euro as a loss and get another brand of mount, that will work ??

Convince me to keep this dysfunctional mount.

Thanks for listening,
Paul

Hi, my experience using the iEXOS 100 over the last couple of years has been excellent. It is a learning curve for sure but by trial and error and with the excellent forum groups available with excellent help also from ES themselves you will be taking some very fine images very soon.
You will also see that I have just started to use the purpose designed iEXOS 100 Polar Scope again with trial and error, I am now managing 2minute exposures without trailing. 
Hope you come to enjoy and appreciate the iEXOS 100, any further advise required please let me know, thank you, Brian

Re: #iEXOS-100 What do I need to mount a DSLR directly to the iexos #iEXOS-100

Wes Mcdonald
 

Parag

As Ian stated the relative pointing of the camera is not important to the mount’s ability to provide you tracking along the path of stars. Alignment is however important for your mount to accurately point your camera at an object using the goto function.  

With the camera mounted and the mount in polar home position (weight bar vertical and dec pointing north, altitude set equal to your latitude) imagine the camera lens can be tilted up or down relative to the vixen bar.  This is called cone angle.   Now imagine the camera can also be twisted left (west) or right (East).  This is called dec home error.   These two errors will be reflected in your pointing.

If you are using a relatively short focal length lens ( about less than 300mm) you can probably not worry very much about these errors.   Your camera field of view will be larger than the errors if you use a little care when adjusting your camera mounting, and get it close by eye.

If you want to go longer focal length you might want to be closer than by eye.

The tilt of your camera can be measured with a digital level I think.  Remove the camera and measure the angle of the vixen bar.  Then install the camera and figure out how to measure the angle of the camera lens body. My guess is that if you have the camera mounted flat to the vixen and tightly screwed on with the  mounting bolt this should be close.

The twist is maybe a bit harder.   One way would be to get the mount aligned to polar home using a compass and your digital level.   Remove the camera and set the altitude of the vixen bar to your latitude.  Then use a digital compass to adjust your azimuth to true north.  You phone will have apps with both of these functions.   If you calibrate your compass it will work ok.  After that mount your camera.  At night adjust the camera mount left or right until Polaris is about in the center of the camera viewfinder.   That should do it.

Finally, before you do your alignment make sure the mount is level.  

With all this done you will find the system will point your camera very well and it will track objects so that you can take time exposures.

Re: #iEXOS-100 What do I need to mount a DSLR directly to the iexos #iEXOS-100

Ian Morison
 

Hi Parag,
    do you mean 'with the lens along the axis of the dovetail' as I suspect?   The answer is that it does not matter at all.  The lens could be pointing at any angle to the direction the mount is nominally pointing as it tracks across the sky.  In fact you could mount a ball and socket joint on the dovetail bar and point the camera in any direction you like.  The mount should, of course, be reasonably well aligned.
Cheers,

Ian M

Re: Thoughts on an ES IEXOS-100 for a beginner #iEXOS-100

Hi S,
I can only say that it is an excellent mount for doing astrophotography with a DSLR and lens or small refractor as I am aiming to do with mine (when we get some clear skies).   My personal view is that it is better to take many short exposure frames (15 to 60 seconds) and then stack them in a free program like Sequator.  This makes the alignment far less critical. In fact I do not want the alignment to be perfect so that the stars move across the sensor during, say, a 30 minute total exposure.  This suppresses color mottling due to variations in sensitivity of the pixels and reduces the effect of hot pixels.  So I would certainly not spend money on a guide scope system but, rather, get some wider aperture prime lenses with the money that it would cost.

I am sure others would disagree.

Enjoy the hobby.

Cheers,

Ian M   ( Mount review etc at   www.ianmorison.com)  There are other articles that may help you too.

Jerry,

I just received my iEXOS-100 mount today and watched the video in your link on how to upgrade the firmware.  In the video, you mentioned files with an 'a' as the version of firmware with watchdog disabled.  I don't see a file for iEXOS-100 with 'a' in it.  Does the latest version of iEXOS-100 come with watchdog enabled?

Thank you,

Re: #iEXOS-100 Maximum weight I can use. #iEXOS-100

James Ball
 

I have extra counterweights and have used it with the standard tripod with up to a deforked C8.  It will be quite shaky when focusing with that much weight but for visual it can do it.  If you purchase the heavier tripod and the azimuth adjuster it will handle quite a bit of weight. 

On my standard tripod it does well with an extra weight and the AT102ED (102\700) scope, That shouldn't be too different from what you have currently..

Re: drift align

Jerry Hubbell - Explore Scientific VP Engineering
 

Hi combatsniper,

The ExploreStars application provides a 2-star or 3-star "virtual alignment" function which is an "all-sky" type of alignment using the stars of your choice.
There are also plenty of resources on the Internet for learning how to do a "physical" drift alignment using your telescope and a cross-hair eyepiece. This is a good one here:
