Bug-Object shifts to the right when using AF on Target Switch in Plan mode

zjW8Hx8Y

S50 Firmware 7.06
EQ mode with values 0.0 and 0.0 in two different “Scope Points” (aka nearly perfect alignment)
"AF on Target Switch" in Plan Settings in ON

Description:
I created a plan using NGC 2403 as an example (the specific object doesn’t matter — the issue occurs with all targets) and started the plan.

The telescope slews to the target.
Then it begins the AF (auto focus) procedure.
After that, it starts capturing the object — but the target is no longer centered in the frame and is shifted a few pixels to the right.

Workaround:
When planning, I place the object slightly to the left edge of the red crosshair — but this is obviously not a proper solution.

Possible cause:
I suspect the issue is related to the AF process. It might be necessary to add an additional GOTO (recenter) after autofocus.

For fairness, to be sure that the issue is specifically caused by AF, I should have disabled that feature and compared the results. However, I won’t have clear skies for the next week.

If anyone else is experiencing the same issue, please leave a comment. Thanks.

zjW8Hx8Y You can first find one or two celestial bodies, center them in your field of view, and ensure they are in correct focus. Once you've confirmed everything is in order, then proceed with your plan. It is not an issue.

Try enabling SkyAtlas Sync in Advanced features if you have not done so. (its turned off by default)
The sync icon will appear next to the Goto in SkyAtlas.

Slew to the target (galaxy in this case).
Let the app settle (live view shows the object, but it's off-centre).
In the SkyAtlas overlay:Tap the red movable frame (the crosshair/target box).
Drag it so the centre of the frame is exactly on the brightest part of the galaxy core (or the visual centre if it's extended).

Tap Sync .This tells the Seestar: "This is where the object actually is — update your internal coordinates to match."
It recalibrates the mount's pointing model using the current position of the red frame.
Future slews to that object (or nearby ones) will be more accurate.
It does not physically move the mount — it just updates the software's understanding of where "centre" is.

After Sync, do a short slew away and back to the same target to confirm it centres better.
Worth a try.

Yes I have seen this too, on S30. The displacement was bigger than in your example - about a quarter of the frame width. It takes several visits to the Sky Atlas and GoTo, to get centred properly.

Nasa-HSIA If this weren’t an issue, I wouldn’t have gotten the same problem across five different objects (all captured using PLAN in the app).

SkyAtlas Sync was ON

It was on but did you sync? That is, manually centre the object and then press "sync"

zjW8Hx8Y

marvindj you might be right

The object being slightly to the right has been there for a long time. I don't think it has anything to do with running a plan or not. I find targets almost always end up slightly off centre to the right. Synching may help. Its usually not a problem as the image can be cropped to better centre them afterwards but annoying it happens. My recollection is objects were better centred in much earlier software versions, so something seems to have happened along the way.

It has nothing to do with the plan
