Planetary live stack planet tracking

Hello,

I put the latest version of SharpCap on last night and planetary live stacking no longer works.
Version is 4.1.14325.0 - 10/30/2026.
When I centered Saturn in the capture window (800x600) on ASI676MC and hit the planetary live stacking button the ROI for Saturn moves far from where Saturn is. Then I get and error indicating exposure is too low, with nothing in the field of course.

The version I was using 4.1.14310.0 worked fine.

Hi,

had you set up the ASI camera to flip the image in either the horizontal or vertical using the 'Flip' control on the right? It's possible that if you have done that then the planetary stacking might say 'move the ROI 10 right', but due to the flip it really needs to be 'move 10 left', which would lead to the ROI moving away from the target.

There are separate options to flip (and rotate) the image in the planetary stacking area which let you get the preferred orientation of your planet without needing to use the 'flip' on the camera.

cheers,

Robin

Here is the issue:
SharpCap v4.1.14165.0 works fine.
The latest version and some previous ones I have test have this problem.
A ROI is set for view a planet.
If camera control is set to flip the image in any way the ROI is moved in the wrong direction to keep the planet centered when center image is checked.
This happens just monitoring the image, no planetary stacking used.
