The best first telescope is the one you can carry outside in one trip and point without a manual. Everything else is secondary.
Aperture is the real specification
Magnification is a result, not a feature. A 6-inch or 8-inch Dobsonian gathers enough light to show hundreds of star clusters and the brighter nebulae from a suburb. Small refractors on flimsy tripods are sold with huge magnification numbers, but their 60mm lens cannot support that claim. Ignore the box's “600x” and look at the diameter of the main mirror or lens.
Mounts decide whether you use it
A manual Dobsonian sits on the ground and moves by hand. It is simple, stable, and cheap per inch of aperture. An equatorial mount tracks the sky but needs alignment and a counterweight. A computerized GoTo mount finds objects for you, at the cost of batteries, setup, and a learning curve. For a first scope, simple and stable beats clever.
Two accessories worth buying
Start with two eyepieces: roughly 25mm for wide views and 10mm for closer looks. Add a red flashlight and a planisphere or a phone app with a red mode. A chair you can adjust matters more than a third eyepiece. Skip the deluxe filter kit until you know what you like to observe.
Look at the Moon first
It is easy to find, bright enough to prove the scope works, and genuinely spectacular near first quarter. Then try Jupiter's moons, the Orion Nebula in winter, and the Pleiades in a wide eyepiece. Those targets teach you to focus, aim, and wait for steady air.
Buy used, carefully
Dobsonians hold up well. Check the mirror for scratches and haze, move the focuser through its range, and look for a dented tube. A local astronomy club star party is the best place to try before you buy, and members often know who is selling.
