I'm using Kstars 2.9.1 in Raspbian. I've found that in the focusing module, I cannot zoom-in above 100%. e.g. I can't do 120% or 150% in the framing setup.
Is this normal?
Plus I use a Bahtinov mask to focus, which I only need the framing and zoom to work. I do not need the star detection and FWHM. I can see the EKOS always try to detect the stars, and draw circles around them. Can I disable the drawing of such circles?
No.
But it turns out I'm suffering from some other problems in the raspbian. I switched to ubuntu and update to the latest version and able to get the zoom working.
