Jasem,

I installed the ds3231 module on my RPI3 (running Ubunto MATE). I read how you had to modify some of the boot and config files to let the RPI3 know its there, but the system still doesn't read the hardware clock from the ds3231 when it boots. e.g., when I first got things going, it was on July 1st, but when I came back a few days later on July 3rd, and typed the date command, it still had July 1st. It I typed hdwclk -r, it read the correct date and time on July 3rd. Somehow, the date and time is still not getting loaded into the system during bootup. I can fix the problem pretty quickly by just typing the "hdwclk -s" command and then the system time & date agrees with the ds3231 time & date. I may have missed a step when installing the clock.

I solved the problem. The issue is that the mount name should be just “Temma” and not “Temma Takahashi”.

Hi Guys,

I’m trying to get Sky Safari to work with my Takahashi Temma mount, but I keep getting the following error message: “Internal client is not connected! Please make sure the mount name is set in the Options Tab. Disconnect and reconnect again.”

In the options tab, I have “Temma Takahashi” for the active devices, and as said in the instructions, LX200 Classic” as the mount type in Sky Safari setup. I also made sure that I have the right ip address and port 9624 in the Sky Safari settings as well.

Clear skies,

Gene Lauria replied to the topic 'Live Stacking' in the forum. 2 months ago

I concur! Something that operates like Sharpcap would be awesome. I am now doing mostly Electronically Assisted Astronomy (EAA) which I think is really going to catch on. I can see so much more with my camera doing live stacking than I can visually from my moderately light polluted (Bortle scale 7) back yard. I currently use Sharpcap and it works great but I still have to use a USB cable which stinks because I control everything else wirelessly with INDI/Ekos. The latest version of Sharpcap however has a mode where you can load the images for live stacking from a folder. You can use INDI/Ekos to put the files in the folder and then load them into Sharpcap. The only problem is that when I tried this when it first came out, you couldn't apply and image processing to the live image (such as color balancing and stretching) so it was pretty useless for live stacking in this mode. However, I tried it recently off-line, (i.e. from a old folder that had some images I took last year) and it seemed to work. I am going to try it again soon to see if the later version now allows for adjustments while taking the images with the camera.

In any event, as you mentioned, it would be wonderful if a Linux developer of this community could make an INDI / Ekos version of live stacking. Perhaps if more of us request this feature maybe Jasem can develop one (like he doesn't have enough to do!)

Gene Lauria replied to the topic 'Takahashi Temma 2 users' in the forum. 3 months ago

Hi Pepcm,

I actually think I did, and it took a while for me to figure it out. I don't think the problem is with the drivers but with the RPi3. The problem is that it doesn't have a battery to keep its memory. What would happen is that the server (RPi3), had a different time than the client (my PC running Kstars/Ekos). My client has the right time, but the pi didn't. The important thing here is that this only happens when I have the RPi3 configured as a hotspot and not via a network connection. If the RPi3 connects to the internet, it updates its clock and everything works fine. However, I find out that if I leave it in hotspot mode, it keeps its last time setting before it is shut down. For example, in my case, if I had the RPI connected to the internet and didn't use it for a month, and hooked it back up in hotspot mode, that's when I ran into trouble. The Temma driver under indi is a month behind and doesn't synchronize to Kstars/Ekos. The symptoms that I see is that it will not point to an object that is low in the East because it thinks it hasn't risen yet or it will go off in some other direction if the object I'm looking for has flipped the meridian.

The way that I found this was through the "date" command. If I typed it I would find that the RPI3 thinks it's a month or so behind the actual date. You can correct this through setting the date using the "date -s " command. (e.g. if you want to set the date to September 3rd at 13:00 hrs. you type: date -s "03 SEP 2016 13:00:00"). The only problem with this is that for some reason, this really messes up the indiwebmanager service and it screws everything up. I particularly find the indiwebmanager very unreliable and do not use it. Since I need a command window to shut down the RIP3 any way, I don't bother with it and just start my INDI drivers manually or through an alias which stars them for me. I find this to be much more reliable than the indi web manager.

In any event, the way that I have fixed this is to either briefly connect the RPI to the internet from time to time so that it updates its clock automatically and then put it back into hotspot mode, or just use the date -s command. Once I do this, the mount points just fine. There may be a better solution out there, but this one works without fail so that's what I'm using. If there are more experienced users who read this message, they may chime in with a better solution, and that would be great if they did.

I think I once heard that the RPI3 should get it's time synced properly once it connects to the client, but this doesn't happen in my case. If in your case, you are using your RPI3 connected to the internet and verified that it has the right date and your mount still won't point properly, then that's a different problem which would be new to me. In all of this for me though, I think the Temma 2 drivers are working properly. It's just that it took a while for me to figure out that it might not be a driver problem but a problem with the RPI3 itself which it was. I'm not a computer person, so it took a long time for me to figure this out and my wife helped me as well since she is pretty savvy with Linux.

The other thing is that one might ask why I use the RPI3 in hotspot mode and just use the internet. Yes, I can do that from home, but if I take my setup in the field where I won't have internet, I don't want to be fumbling with the settings to get everything to work in the field. If I just leave it in hotspot mode, everything will work when I turn it on.

Sorry if I carried on a bit much here, but this was a long process to finally figure out what was going on. Now, the setup works very reliably. Perhaps there is a way for the RPI3 to get the current time when it communicates with the client which would be great. Maybe someone who knows how all of this stuff works a lot better than I do can offer a better solution.

Clear skies,
-Gene

Gene Lauria created a new topic ' Takahashi Temma 2 users' in the forum. 2 years ago

Hi Guys,

Is there anyone using indi / Kstars / Ekos with a Takahashi Temma 2 mount out there? I'm struggling with getting my NJP synchronized. After I polar align the mount on polaris, I start up indi/Kstars and point my telescope to a bright star like Vega. Since I'm doing this in the late summer / early fall, Vega is on the west side of the meridian. When I do this, two strange things can happen. Either is synchronizes on Vega and when I ask the mount to go to a nearby star like Deneb, it goes in the opposite direction. The other thing that can happen is that I synchronize on Vega and I lose the crosshairs. At first I couldn't figure out what is going on, but then later found that they were on the pointed 180 degrees off. i.e., under the horizon in the green zone in Kstars.

Is there anyone else out there using a Takahashi mount with the Temma 2 controller running into the same problem? I've been struggling with this issue since late September and it still doesn't work. I don't know if I'm doing something wrong. However, before I tried using indi/Kstars/Ekos, I was using Cartes du Ciel with the ASCOM driver for my Takahashi mount and followed the same synchronizaiton/initialization procedure and it worked just fine. I just had to tell the ASCOM driver which side (East or West) the OTA was on when I synchronized on the star that I chose.

Thanks,

Gene Lauria replied to the topic 'PhD2 via Ekos on Windows machine while INDI running on RPI3' in the forum. 2 years ago

Thank-you Helge, this was very helpful.

My version of PHD2 was old and I did not see the options shown in your screen shot. I updated my PHD2 and now it works (and makes sense). Before, I was trying to figure out how PHD2 would work because it controls the mount and camera through the COM ports of my laptop which are now located on a remote computer (RPI3) running as the INDI server. I knew that I had to be missing something somewhere, so that's why I wrote the posting.

If anyone else reads this, I might suggest more detailed instructions on section 8 of the Guide Module page in using Ekos. www.indilib.org/about/ekos/guide-module.html Mainly, in the 3rd paragraph, I got lost after the first sentence. It would help if more explanation in what it means to "select your INDI equipment and set their options.", in PHD2. For a newbie like me who's learning how all of this works, more explanation on how to do this would really help.

Gene Lauria created a new topic ' PhD2 via Ekos on Windows machine while INDI running on RPI3' in the forum. 2 years ago

Hi guys,

Newbie dumb question here, I have the following setup:
INDI running on an RPI3 (server), KStars / Ekos running on my Windows Laptop (client).
I've got everything working great using the built-in guider in Ekos, but I would like to run PhD2 instead, which of course, is installed on the Windows client machine. I read the instructions on, www.indilib.org/about/ekos/guide-module.html#h8-using-phd2 , but I cannot get PhD2 to connect through Ekos. The error that I get is that the address is not available. In the profile setup guiding field, I have local / port 0 which must be incorrect. The other problem is that in PhD2, how do I tell the equipment setup for the guide camera / mount to look to INDI for the port information? Normally, I would assign COM1, or COM* if I was not using KStars / Ekos / INDI but I now know this would be redundant.

I just learned about PhD2 build 2.6.3dev7 which now has and INDI option for the port connections, but can't get that to work either. I selected INDI camera / INDI mount and entered port 7624 but that didn't work either. Also, in the Ekos profile, for the guider option I tried, PhD2 / local / port 7624, PhD2 / the IP address of RPI3 server running INDI / 7624 and that didn't work either. Maybe I have to use another port?

Sorry for showing my ignorance here. If there is another link / forum posting with more detailed instructions, please forward me where I might find it.
Thanks,
-Gene

Hi Gerry,

I'm sorry to hear that you had so much grief with your pl-2303 with the raspberry pi, it works great. I had no problem hooking my NJP up and it worked first try once I could confirm that the USB to serial adapter was working.

Thanks Jasem,

See, dumb question. I must have had a non-zero number in the field then. I was doing some test dark exposures to get used to how Ekos works, and I heard the mirror lock up and my darks were showing the bleed through because the amplifier was on since the mirror was locked in the up position. I'll try it again tonight and make sure that the value is zero and see what happens.

Gene Lauria created a new topic ' DSLR Mirror Lock' in the forum. 2 years ago

Hi Guys,

I have a newbie dumb question. How do you disable the mirror lock? I have a modified Canon DSLR and if I have the mirror lock enabled, the internal amplifier stays on and its heat bleeds onto the sensor. I want to disable the mirror lock so the amplifier will only be on only when the image is being downloaded off of the camera.

I see in the INDI Main control that the Mirror Lock has a green light and I want to turn it off, but can't find any control in any of the tabs to do so.

Thanks,

Gene Lauria replied to the topic 'USB to serial adapter for Rasberry Pi to control mount' in the forum. 2 years ago

Thanks,

Ultimately, I would like to use Raspian Lite because since I want to use the Raspberry Pi as a server only, there's no need to have the window interface. I just want to turn it on, have it autostart the INDI drivers and connect to it with KStars / Ekos on my laptop as the client. i.e., I don't intend to use a keyboard and monitor with the Pi, and I hope I won't need one. Just turn it on and go... I think it will take a while with me though since I'm completely new to all this stuff. I always wanted to find an application to use a single-board computer, so this looks like the perfect learning opportunity.

I tried a Prolific 2030 USB to serial adapter with the Pi and it worked. I found this posting in the Raspberry Pi forum ( www.raspberrypi.org/forums/viewtopic.php?f=28&t=146215 ) and was able to see the same messages that are shown after typing lsusb and dmesg commands confirming that it recognized the adapter. Lastly, I started the INDI driver to my mount (Tak. Temma), started it on my client running Ekos, and I was off to the races! :) -Too easy.

Now I'm struggling with getting my Canon DSLR to work. There's a whole FAQ on the subject, but I'm still running into difficulties. However, that will be another forum posting.

Very good Jasem, (My apologies for misspelling you name in my previous mesage.)

Is it that simple with Ubuntu? Since I was planning on using the Raspberry Pi I was trying to keep the overhead low and use a more simple OS. I was actually thinking of just loading Raspian Lite because I didn't think I would need all of extra bells and whistles that comes with Ubuntu Mate.
