Hi Markaus,

Great to hear you have the new scope and a selection of good eyepieces.

You asked about GPS alignment tips, I found that when I first set up my LX200 the GPS alignment stars were so far out that the alignment stars were no where near the field of view of the Guide Scope (often several degrees out).
Even after manually aligning the goto,s were slightly out.

Two things fixed these problems for me (and I think should work with your LX90)

1. Make sure the alignment stars are as close as possible to the exact centre of the eyepiece. (Use an Illuminated Reticle Eyepiece, double cross hair type is good for this)

2. Do a calibrate censors just as the Meade instruction manual suggests.
Before doing this remember during this process the scope will goto Sigma Octantis (Sig Oct - SAO 258857) you will be asked to centre it.(this star is hard to distinguish in the eyepiece if your not familiar with it).Spend some time making sure you recognize it in the eyepiece before calibrating censors even take note of position of scope when centred on it, I used the setting circles on the scope (good to know they are not totally useless or just for show)

The link below has some helpful information as well

After I followed these two steps I noticed the GPS alignment stars were always well within the field of view of the guide scope and often even within the field of view of the eyepiece, only a small amount of precise centering was needed,

All the best with your new scope.

Wayne.
