Hello Wolfgang,

Thank you for the very fast response. From the look of the screenshots it's exactly what I need.

I've run into some difficulty installing the new driver; largely, I think, due to my ignorance and inexperience. I've never done any C coding and have never used cmake.

I followed the INSTALL instructions on branch: stargo-1.9 and after typing cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ../../3rdparty/indi-avalon
Got the message: "bash: cmake: command not found"
Without changing directory (I didn't think of changing until later), I installed cmake
sudo apt-get install cmake
this appeared to install OK

I then ran the INSTALL cmake command again cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ../../3rdparty/indi-avalon
"CMake Error: The source directory "/home/astroberry/indi/3rdparty/indi-avalon" does not exist.

I then followed these instructions at indilib.org/download.html to make sure I had indilib installed

Stable Release
INDI Library is available for Raspbian Buster. To install stable INDI Library, run the following commands:

wget -O - www.astroberry.io/repo/key | sudo apt-key add -
sudo su -c "echo 'deb www.astroberry.io/repo/ buster main' > /etc/apt/sources.list.d/astroberry.list"
sudo apt update

No errors were reported. It appeared to install cleanly.

I then went back to your INSTALL instructions and to avoid the error with not finding the 3rd party/avalon-indi directory, I ran

cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug
Cmake started to run but after 24 or so lines of print-out said

-- CFITSIO not found.
