Product description:
AC 90/900 optics.
This optics is equipped with an achromatic objective. Because of a special combination of two lenses within the objective, most of the colour aberrations can be corrected. Thus, you do not have to face so many disturbing irregularities as usual with common Fraunhofer refractors. The aperture ratio of 1:10 has an additional positive effect.The EQ-3-2 mount:This parallactic mount is already provided with the means for aligning the optics precisely on the Pole Star. It can be set to the correct polar elevation and geographic latitude for any observing site. Objects can be precisely positioned in the field of view using the flexible slow-motions and then tracked in both right ascension and declination. A counterweight ensures precise balancing of the optics. The mount provides a stable base for most small to medium-sized optics and is ideal for exploring the night sky. Motors are available for the EQ-3-2 to provide automatic tracking, which will then also your first experiments in astrophotography possible.
