I've been experimenting with itelescope.net and tried to observe Sgr A*.
I was wondering if there are any suggestions how I can best observe the surrounding stars.

I expect that all the itelescope.net instruments work at visible wavelengths. Therefore you have no chance at all to image the stars around Sgr A*, since it is behind about 25-30 magnitudes of optical extinction.
The published images you have seen were taken by large telescopes working with adaptive optics in the near-infrared (wavelengths longer than 1.5 $mu$m). At these longer wavelengths the extinction is only 2-3 magnitudes.
