Everything now works great except for the function "center here", I will give it a try with Elbrus because it fails at step 1.
Regarding my issues with auto centering options, I understand one must setup your imaging session before leaving home, either set manually the coordinates or import an image in the sequence menu for getting the coordinates.
But if you are outdoor and you just want to center a target, without having first populate the target, the function solve and sync will not center the target. It just get the coordinates.
So if your mount is a bit off, there will be an offset between the target coordinates from the sky chart and the coordinates from SGP. And I usually don't do alignments points, never need it with Astrototrilla,
So I just miss Astrotortilla for this purpose, as it can blindy center a target from the tracking coordinates =
1) Solve and Sync the scope
3) Detect the offset
4) Re-slew to target
5) Target in the crosshair
One-shot process !
