It is almost like there should be 2 algorithms at play. First, run an annular/ring detection, reduce that, then switch to the point/star detection.

This appear to be a problem with Wayland and proprietary video drivers (at least in my case). If I set the system to use X11 instead of Wayland, the pointer is back, and everything works fine. It also feels faster. I am using proprietary nVidia drivers with a 3070.

Of note, kstars sky map changes the default cursor to an `X`. I do not remember this being the case in older versions of kstars, so it could be something in Wayland doesn't handle the custom hardware cursor?

I missed this post, but have the same problem. I am looking to see what to do to fix it. The pointer works in every other aspect, except in the main kstars window. The pointer appears when you grab and pan, and when you left-click, but as soon as you move to the main screen, it is gone.

just a thought... If color coding is the direction, allow the user to choose some of the colors to help different contrast settings, color blindness, themes, etc.

Would it be possible to have the system determine what the step size should be in some way each session? The starting step for determining the final step size could even be calculated from the user's equipment configuration. Store this value and use it as the seed for the next time an auto-configure of step size is run.

eqmod guiding is direct control of the mount, where ST4 is older and slower, and designed to communicate directly from a camera

I wonder if the eqmod driver should reject large deltas that are reported from the mount. With the tracking or slew rate being known, a factor could be applied to ignore values outside of a possible range. I have seen jumping too, and went through a period of cable replacement, power supply replacement, etc. Mine doesn't do it often now, but it is very annoying when it does, and can even be dangerous to the mount and equipment when its actual location is different than what kstars shows.

Looking at the AC side may show you noise. If there is an AC signal of any strength, or even worse, fluctuation, it could be a power supply issue. Since your DC voltages are fairly stable though, it is likely a well-regulated power supply, and AC should be minimal if it is working correctly.

It was mentioned a few times about having a nebula in the frame possibly throwing things off a bit. Between that and edge of field optical distortions, I settled on an annulus configuration of 15% / 55%. This gives me a nice donut that avoids the center of the field where a nebula might be, and the corners of the field, but still has plenty of star quantity inside the large donut. I have full field checked with this configuration, and it seems to work quite well for my needs with the linear algorithm.
