FAQs

Still have questions? We have answers.

What can I see through a 4-inch telescope?

With a 4-inch telescope, you can expect to see a variety of deep-sky objects including nebulas, galaxies, star clusters, and planets. You will also be able to view the moon's craters and other surface features in detail. In addition, using higher magnification eyepieces (200x or more) you may be able to see details on Saturn's rings or the stripes on Jupiter.

Can you see deep-sky objects with a 4-inch telescope?

Yes, with a 4-inch telescope you can expect to see a variety of deep-sky objects including nebulas, galaxies, star clusters, and planets. However, due to the limited size of the telescope's aperture (the diameter of its primary mirror or lens), most of these objects will appear small and faint. It will take some practice to be able to identify them in the night skies.

Can you see galaxies with a 4 inch telescope?

Yes, with a 4-inch telescope you can expect to see a variety of galaxies. However, given the limited size of the telescope’s aperture (the diameter of its primary mirror or lens), most galaxies will appear faint and small.
