Two models, the numbers decide

Sky-Watcher Skyliner 150P Classic or Sky-Watcher Skyliner 200P?

Sky-Watcher Skyliner 150P Classic — 150 mm, €357. Sky-Watcher Skyliner 200P — 200 mm, €449. The same method as everywhere on this site: the numbers first, the verdict from them.

Same family (150–200 mm Dobsonian): what changes between these two is aperture, bulk and price — not character.

These circles are simulations, computed from the aperture, the magnification and the sky — indicative, not exact. A real night also depends on the turbulence, your eyes and your experience. Closer to the truth than the photo on the box; still not a promise.
