Two models, the numbers decide
Sky-Watcher Evostar 72 EDX or Svbony SV503 80ED?
Sky-Watcher Evostar 72 EDX — 72 mm, €449. Svbony SV503 80ED — 80 mm, €430. The same method as everywhere on this site: the numbers first, the verdict from them.
Same family (72–80 mm ED refractor): what changes between these two is aperture, bulk and price — not character.

The same sky, through both
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.
