I've been having a problem with my mount not tracking correctly recently. I use Stellarmate for mount control and guidance and the first thing I noticed was when polar aligning I would get the message... Mount aborted. Please restart the process and reduce the speed... so I reduced the speed and got the same message this happened repeatedly. I eventually managed to get an alignment and tried some images When I did the first thing I noticed was the reticle on the screen of my laptop was jumping about in an EW or NS direction. Then it started drifting as the object I was photographing moved westwards. I'm guessing from what I observed on the calibration plot this also happened during polar aligning. Checking the mount settings tab and the tracking had shut down. The following night I set up again to go through the mount and the complete system having done a quick Internet search to find the problem may well lie with connections. I know the RPi3B+ is a bit fussy over the power supply so I reverted to my original power setup that had worked for the past two years with no problems and had a good 15 minute run. After a second 15 minute run which showed one problem I swapped to the official RPi power supply even though the new board exceeded the spec of the official supply. After some experimenting I found the official supply appeared to give the best performance with a 20 minute tracking run and no errors. .The following night again I replicated this set up outside and immediately started to see the same errors despite now using the official RPi power supply. So after gathering some images I noted the reticle flicking about on the screen didn't appear to make a difference to the image quality. Problems only became apparent when the mount tracking was turned off which is to be expected. I then powered down and disconnected the RPi and the Lynx Astro FTDI EQDIR USB Adapter and attached the hand controller to the mount which then tracked perfectly. So I don't believe it to be a mount issue. The Lynx Astro lead is also in good condition.
I did note on checking that the RPi's RTC had lost the time and It has occurred to me that this may be the reason although I can't really see how. Checking on the forums I know this problem has occurred on two other occasions but apart from some questions about mount behaviour there has never been a solution mentioned. Has anyone else been experiencing the same problem and how did you resolve it? I'm currently thinking of reinstalling Stellarmate on the RPi but is there something I may be missing?
I've attached an image which shows the effect visually and I've added a logfile for information.
Any thoughts would be appreciated.
Been using the Stellarmate app for a while and have finally been able to get some images. But what a useful app it is, all credit to the developers...Been using the Stellarmate app for a while and have finally been able to get some images. But what a useful app it is, all credit to the developers
Attached is my take on Bode's galaxy and the cigar galaxy shot with a Canon Eos 550D on my skywatcher 200p explorer mounted on a HEQ5pro
Wish list item for the app is night mode.
Thanks again to the team for such a useful app Show more
Great update it has arrived and it does what it says on the tin. Great work to all the team really appreciate it. I can now control my mount and cameras from my tablet device. As I have changed laptops I decided to update SM to the new version and then everything fell into place. The only curiosity I have noticed is that the switch from hotspot to router is not a clean switch as I usually have to delete the device and rescan before being able to connect when changing networks but in fairness that is accomplished in seconds so no real problem in the long run. Just waiting for some clear skies to test it all out with. Thanks guys for all your hard work.
Thanks for the suggestion but I've already been down that road with no joy. I'm told by Jasem it may have something to do with Ekos live which is being updated in a soon to be released update.
Yep I've reinstalled the app on the tablet and done a factory reset on the Stellarmate gadget and still can't connect. Simply the getting the same loop as before. Even though the gadget and the tablet are on the same network.
Frustrating! So any ideas would be well received.
I've a new Android tablet device and logged on and registered the stellarmate device. Then it seems to go into a loop where it takes me to an authenticate screen at which point I enter user name and password and the app tries to connect to the stellarmate. When that fails it takes me back to the authenticate screen. I enter the same user name and password and it tries again to connect to the stellarmate device. eventually taking me back the authenticate screen. I've tried with the stellarmate hotspot and via my router and still can't connect.
Don't know what I'm doing wrong but any help would be appreciated.
Is there any news of when we are likely to see an update of the Stellarmate app from the Google Play Store as it does not run under Android 9 being version BETA 1.9.14(Bundle v42) and the Stellarmate site says it won't run under Android 9.
Thanks for any information.
After my trials with connection issues I finally have seen the power of this amazing piece of software. I can only say how remarkable it is that amateurs can home in on a tiny point in space and photograph the object that is lying there. Watching plate solving work was a eye opener and then to see the object I wanted smack bang in the middle of the FOV was something to behold. I think I am beginning to really like this software. Unfortunately cold autumn nights also bring dew and my time at at the telescope was cut short as I need to fit my dew heaters. I had seen what I wanted though and it was amazing.
So my thanks to the team who have created this software system which combines everything in one package. You have done a great job.
So that's how it is done. I've been having the same problems and saw your response and tried it. No more problems. Thanks.
With another good night I thought it time to check what is happening and see if I can reproduce the same unparking issues and see them on the log files. Well I had the same problems but didn’t reset the logs from default to file as I thought the default would create a file. So no file again So having found how to create a file I decided to do a test run from Parked to Vega then to Cappella and finally Alpheratz. I noticed during this run that it took some time to complete and on examining the logs noted that there was a loss of communication with the mount on five occasions. See the attached logs, one direct from Kstars and the other where I have highlighted the disconnects.
For information here, I am running Stellarmate connected to the Synscan WiFi dongle plugged into the mount - no FTDI cable. I use a MacBook Pro which is connected to the dongle via WiFi thus completing a small WiFi based network. Apart from the unparking issue this has worked well enough on test in the past and on one occasion when I did a visual survey, going from target to target was faultless.
What I am wondering is if there any Gremlins getting in with using two devices which are both trying to create hotspots although I have made the Synscan a connection on StellarMate. But are they competing with each other to have control? - Don’t know. Not enough of a networking Geek to be able to answer that one.
What are the thoughts of those of you who have tried this and is it worth scrapping the idea of using the dongle and buying an FTDI cable to give me a hard connection between mount and StellarMate and simply using the StellarMate WiFi connection from the Mac.
Your thoughts would be appreciated
