Here's a review of the Celestron Eyepiece-

The Celestron 10mm Eyepiece is a high-power eyepiece designed for close-up views of celestial objects. It’s typically included in many telescope accessory kits, offering detailed views of planets, the Moon, and other astronomical targets. While it’s a more budget-friendly option, it provides solid optical performance for both beginners and intermediate astronomers.

Product Overview:

  • Focal Length: 10mm
  • Optical Design: Most commonly available as a Plössl or Kellner eyepiece, providing a sharp and clear view with a relatively simple design.
  • Apparent Field of View (AFOV): Typically around 50°, which is common for Plössl eyepieces, providing a narrow but focused view that’s ideal for high-magnification observing.

Optical Features:

  • High Magnification: The 10mm focal length offers high magnification, making it perfect for zooming in on the Moon’s craters, planetary details like Jupiter’s cloud bands, and Saturn’s rings.
  • Multi-Coated Optics: Depending on the specific model, Celestron’s 10mm eyepieces often feature multi-coated lenses to improve light transmission and reduce glare and reflections, ensuring bright and sharp images.

Performance and Use:

  • Planetary and Lunar Observation: With high magnification, this eyepiece is best suited for detailed views of the planets and Moon. It’s excellent for seeing surface details, like the phases of Venus or the cloud bands of Jupiter.
  • Narrower Field of View: As with most high-power eyepieces, the field of view is relatively narrow, which means you’ll see less of the sky at once, but it allows for zoomed-in views of specific objects.
  • Bright Objects Only: Because of the high magnification, the image may appear slightly dimmer compared to lower-powered eyepieces. This makes it better suited for bright objects like the Moon and planets rather than faint deep-sky objects.

Here's a review of the Orion Eyepiece-

 

The Orion 17mm Eyepiece is a mid-range eyepiece that offers a good balance between magnification and field of view, making it ideal for a variety of astronomical observations. Its focal length is well-suited for general-purpose viewing, from planetary details to wide-field deep-sky objects like star clusters and nebulae.

Product Overview:

  • Focal Length: 17mm
  • Optical Design: Typically offered in Plössl or similar designs, known for sharp, clear views across a wide field of view.
  • Apparent Field of View (AFOV): Typically around 50° to 60°, providing a comfortable balance between magnification and a wider field of view, allowing you to see more of the sky while still offering moderate magnification.

Optical Features:

  • Moderate Magnification: The 17mm focal length offers medium power, making it suitable for a range of targets including the Moon, planets, and deep-sky objects like star clusters and nebulae.
  • Multi-Coated Optics: Orion eyepieces usually feature multi-coated lenses, which improve light transmission and reduce internal reflections, resulting in brighter, clearer images with enhanced contrast.

Performance and Use:

  • Versatile for Different Observations: With moderate magnification, the 17mm eyepiece is versatile, offering detailed planetary views while still providing enough field of view to observe larger deep-sky objects.
  • Comfortable Eye Relief: Medium focal lengths like 17mm generally offer comfortable eye relief, making viewing sessions easier on the eyes, especially for those who wear glasses.
