Good morning,

and sorry for my english. I use google.
For the first time after a long time, I had the pleasure of making a few pictures again, if only for testing from the moon.
I also had my new control, an "Onstep" on the EQ6 for the first time.
The OnStep runs without any problems with KSTARS/EKOS.
But i cannot drive a star or moon in my case, under a certain height by means of Goto.
Spica goes, Antares doesn't work. I get an error message.
"Error Onstep Slew/Syncerror: Below the Horizon Limit .."

Does anyone know how to fix this error?
If This a Kstars/Ekos or a OnStep Problem ?

Hi Guys,
I hope I ended up in the right sub-forum.
I bought a Raspberry Pi HQ camera and connected it to a Raspberry Pi Zero W.
Raspian runs as the OS on the camera.
The camera works and I can take pictures and videos with raspistill and raspivid.
Long exposure up to 200 seconds are also possible.

Now I wanted to use the camera with Ekos.
The Indi web manager is running on the camera and I have selected the RPI camera as the driver.

When I start ekos I can connect to the camera.
However, I can specify whatever I want as the recording time, whether 1 second or 3 minutes, the images are all equally bright.
What am I doing wrong or do I have to adjust so that I can record different exposure lengths?

I'm grateful for any info / help :)

Greeting
Thomas

Does anyone have an ideas why I can't install the Indi driver for the Raspberry PI HQ camera?

Jasem why doesn't it work with your repository?

www.indilib.org/raspberry-pi/raspberry-pi-camera.html

I cannot download the indi-rpicam file.
The computer cannot find the file. :(

Is there another way to install the file on the computer?

Raspberry Pi 4 32bit Ubuntu-mate 20.04

Hello jasem,
I use ubuntu mate on the raspberry pi 4 and have the same problem there.

hi Guys,
I'm currently trying to install indi-rpicam on linux kubuntu 20.04 64bit and ubuntu mate 32bit. Unfortunately the system cannot find the file.
I use kstars with ekos and will soon get my raspberry Pi HQ camera and therefore wanted to prepare both of my systems.
My Raspberry Pi 4 runs under ubuntu mate and controls my telescope.

My laptop runs with Kubuntu and I use it to log into the Raspberry Pi via VNC.

I did the following:

sudo add-apt-repository ppa: mutlaqja / ppa sudo apt-get update sudo apt-get install indi-rpicam

unfortunately the package was not found.

sudo apt install indi-rpicam
[sudo] password for thomas:
Package lists are being read ... Done
Dependency tree is built.
Status information is read in .... Done
E: Package indi-rpicam cannot be found.

What am I doing wrong ??

Hello Magnus,

I'm sorry if I only get around to testing it now.
Strangely, it works on the laptop now. I just have no idea why that is. I haven't done anything on the laptop.
It works even after restarting it several times and plugging the cables back and forth.
So the way it looks everything is fine. Thank you :)

Hello Magnus,

Sorry I forgot to mention the relevant data.
The OS runs on the laptop Kubuntu 20.04
It's the same version as on the PC.
I installed Raspian (Buster) on the Raspberry PI 4.

Kstars and INDI come from Jasems ppa and are up to date.
They are the same as on the PC.
Kstars = Build: 2020-08-28T23: 44: 14Z
Indi = INDI Library: 1.8.6

Yes, the shutter cable runs smoothly on the Raspberry and the PC.
The EOS 350 also registers as the EOS 350.
I created a UDEV rule for the shutter cable and my EQ6. The shutter adapter is /dev/eos_shutter
The EQ6 adapter is called /dev/monti_eq6.

I can't get to the devices at the moment.
When I get back to the laptop, I will attach an Indi Log.

Good morning Magnus,

I have exactly the same problem with my laptop.
The camera is set to "M" and "bulb".
USB cable and shutter cable connected to the camera.
Recording started with 40 seconds.
When you start recording, the camera suddenly shows 30 "instead of" bulb ". The camera records 30 seconds, the computer counts down from 40 seconds.
The recording is only 30 seconds.

The shutter cable with the USB adapter works perfectly on the PC and the Raspberry Pi and I can expose for longer than 30 seconds.

I deleted / uninstalled kstars-bleeding and all the config files on the laptop and reinstalled everything without success.
I cannot find the error in the settings.
If you managed to get it to work, then it can only be due to the settings, only where ???

Any idea ?

Good Morning,

Yesterday I soldered the cable using Magnus' link and it works fine.
Thanks again for the support. :)

Hello Magnus,

thanks for the link, but I have already found it and am rebuilding it. I still have an FTDI lying around here that I don't need, I'll convert it. :)

Okay you two

let's stick to English out of politeness :)

So Magnus you had 2 USB cables on the camera.
One cable for triggering the camera (Ekos) and one for data transmission from the camera to Ekos.
Fine :)

I saw you were busy researching the Bulb history of the camera in 2016. :)

So I need a shutter release cable. Understood.

@ jasem
forget the story with the arduino :)

Thank you both I will try to find data about it and build or get one.

Hallo Herrhausen,
Hmm, ja schon klar, nur wie löst Magnus die Kamera aus ??
Das Kabel steckt im PC. Vernachlässigen wir einmal den RS232/USB-Adapter. Wenn ich das richtig verstehe dann hat Magnus auf der einen Seite einen PC mit RS232/USB Ausgang - Kabel mit 2,5mm Klinkenstecker in die Kamera.
Da muss doch ein Adapter dazwischen sein der die Seriellen Signale in einfache Schaltsignale umwandelt was die Optokoppler/Relays/Transistoren ansteuert.

Sorry ich stehe da irgendwie auf dem schlauch.

Gruß

Hello Magnus

I've made myself a little smart.
www.gphoto.org/doc/remote/

"gphoto2 --get-config shutterspeed" gives me a list of numbers that correspond to the exposure time.
"0" would be for me = "bulb"

"gphoto2 --set-config shutterspeed = 0"
Puts the camera in "bulb mode"

The following command shows that the camera does not recognize the "bulb" command.

"gphoto2 --set-config shutterspeed = bulb"
"gphoto2 --set-config bulb = 1 --wait-event = 30s --set-config bulb = 0 --wait-event-and-download = 2s"

The camera does not recognize "eosremoterelease = Immediate".

thomas @ work computer: ~ $ gphoto2 --list-config
Detected a "Canon: EOS 350D (normal mode)".

As you say, the problem is with the camera :(

A question for Jasem.
Is there a way in Ekos to control an Arduino so that it triggers the camera via optocoupler / relay?
That would also solve the problem with mirror lock-up.
I think some older cameras have the problem, not just the Canon EOS350 (rebel xt)
The Arduino could handle the mirror lock-up and exposure time.
When the recording time is up, the Arduino sends a "done" and Ekos reads the image.
It's just an idea.

Hello Magnus

I'm German.

I can't do anything with the timer, I don't think I still have the old software. I built the timer 10-15 years ago.

If I understand you correctly, then you use a cable with a 2.5mm jack on the camera and an RS232 adapter on the other side which goes into the PC?

So you have 2 cables on the EOS?
One cable for USB data and one for triggering?
Which software do you use for the control, EKOS?

Please excuse the many questions, but you made me curious. :)

At the moment I can only record a maximum of 30 seconds. That is not a problem, but there is a lot of data. In addition, the mechanics of the camera will suffer over the years.
