Review on 🔭 Celestron FirstScope 21024 Telescope by Brandee Diaz

Revainrating 3 out of 5

The best binoculars and scopes for limited use

The Celestron First Scope looks good, is made of quality materials and is superbly finished, but the ergonomics and optical performance are disappointing. Ergonomics are good at large elevation angles of 60 to 90 degrees, but at lower elevation angles of 45 degrees or less you have to bend over the top of the scope to see the eyepiece, which is uncomfortable and often results in the scope breaking meeting. chest or abdomen. It would be much better to mount the eyepiece on the side of the tube than on the top. The focus control works very smoothly, but is located to the left of the eyepiece, which is impractical for right-handers. Again, the side eyepiece would allow both left- and right-handed focusing. Also, the pivot point on the barrel of the scope should be closer to the center of gravity for easier and smoother elevation adjustment. Optics: When looking at the crescent, the craters were clearly visible with mediocre sharpness. When observing the planets, the image quality in my telescope was completely insufficient to see details such as the color bands on Jupiter or the rings of Saturn. Jupiter's three moons were visible as small stars in a row. Neither focus position with either eyepiece produced clear, sharp images of the planets, although the mirror alignment appeared correct on my initial inspection. The terrestrial daylight images looked quite sharp, but of course they were inverted. Unfortunately, the inverted prism eyepieces available as accessories are not fully suitable for Newtonian reflecting telescopes and are not recommended. In summary: quite good for observing the moon and possibly star clusters, but not very suitable for observing planets or terrestrial objects.
