Features of the Celestron 21024 FirstScope Telescope

  • 3 “/76mm opening
  • 12″/ 300mm focal length
  •  3.9 Focal ratio
  • Parabolic primary mirror
  • 2 eyepieces, 20mm 15x + 4mm 75x
  • Stable Dobsonian mount

The FirstScope from Celestron has a primary mirror with a diameter of  3 inches or 76 mm and a focal length of 12 inches/300mm. The resulting focal ratio of 3.9 puts this telescope with the faster ones making it suitable for observing faint objects and stars of up to about 11 magnitudes.

Two eyepieces are included, the f 20mm ocular provides a  15x magnification, and the f 4mm ocular provides a magnification power of 75x. Use the lower magnification and take advantage of the large field of view to scan larger parts of the sky and use the higher magnification eyepiece to get detailed views of objects of interest. The optics produce decent quality and sharp images. You can see details of lunar craters, see Saturns ring, Jupiters  4 large moons, phases of Venus, or see our neighbor galaxy Andromeda.

Not much in terms of assembly is necessary. Simply place the FirstScope Telescope on a table and start watching. The Dobsonian mount allows quick and easy navigation in all directions over the starry sky.

There is no Finderscope in the basic package. The low magnification eyepiece must do.

However, the FirstScope Accessory Kit includes a Finderscope, two additional eyepieces, a moon filter, and a carry bag for everything.


  • Lightweight and portable
  • Simple swift set up
  • Very easy to use
  • Stable Dobsonian mount
  • Great value beginner telescope


  • A pure beginner’s instrument
