Start with telescopes for beginners, which explains aperture, mounts and useful magnification before comparing starter scopes. For aperture per dollar, Sky-Watcher calls Dobsonians "light buckets": see Dobsonians; for low-maintenance scopes, refractors; for scopes that point themselves, computerized telescopes. Head-to-heads: NexStar 6SE vs 8SE, StarSense DX 130AZ vs LT 114AZ, AstroMaster 130EQ vs PowerSeeker 127EQ and Classic 200 vs Flextube 200. Specs come from Celestron, Sky-Watcher and the Amazon listings; we don't test telescopes.
