brew edit kstars

worked like a charm.

I use homebrew for almost all software on macOS and therefore for KStars as well. The only time I do not use it is when the package is not available via homebrew, which doesn't happen often. It usually works very well for me and now I know how to solve checksum issues as well if they ever happen again.

Hi,
I am trying to install KStars 3.6.2 on macOS via homebrew and get a checksum mismatch. Can someone fix that please?

$> brew update && brew upgrade --greedy && brew cleanup; mamba update --all -y

The info on how to get INDI for Raspbian is outdated. Simply use

wget -O - https://www.astroberry.io/repo/key | sudo apt-key add -
sudo su -c "echo 'deb https://www.astroberry.io/repo/ bullseye main' > /etc/apt/sources.list.d/astroberry.list"
sudo apt update
sudo apt install indi-full kstars-bleeding
and kstars installs fine on Raspberry OS 64 bit.

However, running it turned out to be problematic:
$ kstars

So I copied the ~/Library/ApplicationSupport/kstars directory from my MacBook to ~/.local/share/kstars on the Raspberry Pi and now it's working.

The focal length of a lens or telescope is independent of the size of the sensor of the camera used. So 200 mm remains 200 mm regardless of if you use a 1 x 1 mm sensor or a 100 x 100 mm sensor. Ekos can indeed compute the new FOV but you need to clear the DSLR info in the imaging tab before you start imaging. There is a trashcan icon that you need to click and then Ekos will ask you for the new info.

There is no proper ADU value for 8 bit since you should not take 8 bit imagesĀ silly.png For 16 bit many people suggest to have the peak in the middle (which would be around 32000 ADU) but I advice to go much higher (around 55000 or more as long as you don't get saturated pixels) to make the best use of the full dynamic range of the sensor.

Adding to that, why don't you shoot at 16 bit RAW? That is the preferred format for the ASI533MC camera.

What camera do you use? Is it a DSLR or an Astro CMOS camera? If the latter, what offset are you using and are you sure that the offset for the lights and darks is the same?
