Great value for money starter telescope from Celestron.
The Astromaster 80mm AZS refractor has an erect image diagonal, meaning it can also 
be used for terrestrial objects.
Although not suitable for Planetary work, the short 400mm f5 OTA makes it perfect for low power / 
wide field of view views or rich field star clusters, galaxies, comets and nebula from dark sky locations.

Also with the addition of a t-ring (not included) makes a great wide field imaging scope when 
used with a driven EQ mount. And also a guidescope when mounted piggy back on your 
main telescope.

Easy to set up and use, it is ideal for starters and can easily be folded up and placed on a rear car seat.

Solar Warning
  • Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
  • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
