The new Apertura AD6 introduces “ultra-portability” to the High Point Scientific Apertura Dobsonian lineup which also includes 8”, 10” and 12” versions. Its ease of use is a great option for those new to amateur astronomy and offers all the needed accessories out of the box. It is small enough to pack into a sedan, offering a great option for sidewalk astronomy or taking to dark sky sites.
The Apertura AD6 Dobsonian comes equipped with a diffraction limited 6″ primary mirror made in Taiwan. The altitude and azimuth movements of the Dobsonian base are intuitive and facilitate ease of finding celestial objects with its 6×30 optical finder and the included 9mm 0.39-degree Plossl eyepiece and 25mm 1.08-degree Plossl eyepieces.
The 93% reflective mirror is finished with an aluminum and silicon-dioxide coating providing the viewer with the brightest possible views through the eyepiece. The large thumbscrews on the primary mirror cell allow for simple collimation adjustment and optical alignment. The smooth Alt/Az movement of the optical tube and base lends itself to the quality of construction and to the quality of the altitude and azimuth bearings. The dual-speed focuser allows for precise focus adjustments.
