Apertura AD10 Dobsonian
The Apertura AD10 is the 10-inch sibling of the AD8 — a 254mm Dobsonian that brings serious aperture to a manageable, self-contained package. Sold exclusively through High Point Scientific in the US. Like the AD8, it shares optical heritage with the Sky-Watcher Skyliner 250PX but comes with upgraded accessories including a dual-speed 2-inch Crayford focuser and 9x50 right-angle finder. At 254mm aperture, galaxies, globular clusters, and planetary nebulae show detail that 6-inch and 8-inch instruments can only begin to reveal. CN and Reddit regulars consistently recommend the AD10 as the natural upgrade from the AD8 for observers ready to commit to aperture.
