Two models, the numbers decide
Bresser Messier 6" Dobson or Sky-Watcher Skyliner 200P?
Bresser Messier 6" Dobson — 152 mm, €359. 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.
