The best telescope for Messier objects
Messier objects range from naked-eye clusters like the Pleiades to faint galaxies around magnitude 10. Two things matter most: aperture (how much light the telescope gathers) and how easily you can find things.
Aperture: what you'll see
- 4–5 inch: every Messier object is reachable under dark skies. Clusters look great; galaxies look like soft glows.
- 6–8 inch: the sweet spot. Globular clusters like M13 begin to resolve into stars, and you can make out the dust lane in the Sombrero Galaxy (M104) and the spiral shape of M51.
- 9.25–11 inch: galaxy detail and much more from suburban skies.
