Hi,
I do not know about your luck but I finally made guiding with HiQ camera working and it seems I have brilliant results.
SNR for 35/135 and 60/330 telescopes is baffling 300-800.
Now the hard part
How I made it work.
So I used indi-rpicam driver. That driver has few faults, downloading is slow ~7s, and as I found out later 1s exposure does not work, binning is not implemented.
So I edited driver, first thing I did is hardcoded 2x binning and this instantly reduced download speed to ~1s and from ekos images were brilliant
But every time I tried to turn on PHD it got stuck and timeouted. Later on I noticed that even from EKOS 1s exposure would freeze whole cam. So i went code digging and foud oart of code that says if shutter_speed > 100000(1s) do something too smart for my brain to understand. But i noticed it is only bigger than 1s so I added >= there and that solved all of my problems.
After this I have brilliant guiding performance, on around 20 targets I pointed to i never had trouble finding guidestar, and lowrst SNR I got from 1s was ~200
In the thread below(end of page 6) you can find changes I did for enabling binning
indilib.org/forum/ccds-dslrs/6990-driver...camera.html?start=60
I will not make pull request for this as it is hardcoded binning, and my free time and knowledge about ekos is not good enough.
As for 1s bug, I do not have code at the moment but search for 1000000, there is not much millions in code, and replace > with >=
I will maybe make a pull request for this fix in near future if i configure git.
Quick guide how to install this edited driver:
Clone git for indi 3rd party if you knkw. git or just download only indi rpicam.
github.com/indilib/indi-3rdparty
Save it to
~/Projects/indi-3rdparty/indi-rpicam
Then open Terminal and type this only first time(prerequisite):
sudo apt-get install libnova-dev libcfitsio-dev libusb-1.0-0-dev zlib1g-dev libgsl-dev build-essential cmake git libjpeg-dev libcurl4-gnutls-dev libtiff-dev libftdi-dev libgps-dev libraw-dev libdc1394-22-dev libgphoto2-dev libboost-dev libboost-regex-dev librtlsdr-dev liblimesuite-dev libftdi1-dev libgps-dev libavcodec-dev libavdevice-dev
sudo apt-get -y install libindi-dev
And then type this in
mkdir -p ~/Projects/build/indi-rpicam
cd ~/Projects/build/indi-rpicam
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ~/Projects/indi-3rdparty/indi-rpicam
make -j4
sudo make install
I made all this from my phone so typos and errors might happen.
And that is it, you are good to go.
Happy coding and happy guiding.
