Plan where it will live.
Allow for the tube and base when choosing storage and a route outside. This is telescope kit mass, not packed shipping weight.
A large reflector built around visual observing.
The 305mm reflector uses a floor-standing Dobsonian base with adjustable altitude tension. Its 2-inch Crayford focuser includes an extension tube and a 1.25-inch adapter. Check the component weights and dimensions against your storage and carrying route.

Good to know.
Check your phone first.
App guidance needs a compatible smartphone. Use the StarSense Explorer phone compatibility checker for the current supported devices.
Mirror alignment is part of ownership.
The included collimation cap helps you check the mirrors. Follow the model-specific procedure in the Dobsonian instruction manual when adjustment is needed.
Use it safely around the Sun.
Never point the telescope at the Sun without a proper solar filter over the front aperture. Never use an eyepiece solar filter or Herschel wedge. Adult supervision is essential when children are present.
