Sky-Watcher Flextube 250P SynScan Dobsonian
Best portable large aperture telescope for dedicated backyard astronomers.
This large-aperture telescope balances significant light-gathering power with a clever collapsible design that makes transport surprisingly manageable. The motorized base and dual-encoder system offer the best of both worlds: automated object tracking and the freedom to manually nudge the scope without losing alignment.
