This is our first telescope, our son got this for Christmas. The telescope was assembled quickly to the enclosed instructions on Christmas Eve. The tripod is a little shaky, but we have also deliberately bought a high end device. The alignment of the mirror was a bit gefrickel that screw on primary mirror did not match the manual. Two emails to Astro Shop with a knowledgeable answer could but to help you here. The first halfway starry sky, we watched the stars. Jupiter with the Galilean satellites has already triggered a first wow. Slightly blurred and disappointing were the first observations with maximum magnification. However, this was not on the telescope itself, but to the not entirely favorable conditions of the atmosphere. Now with the current freezing temperatures (-17 ° C) and the stars clear sky a great observation was made possible with well has cooled telescope at the highest magnification. The equatorial rings of Jupiter are clearly visible and for us that was quite impressive.
