Coma Corrector 2" 1.0× Sharpstar

The Sharpstar 2" 1.0× Coma Corrector is a high-quality accessory designed for newton users wishing to improve their images by correcting coma without altering their instrument's focus ratio. This corrector is specially designed to offer full field coverage with optimum correction, enabling full-frame imaging without distortion.

Telescope compatibility

The Sharpstar 2" 1.0× coma corrector is compatible with Newtonian parabolic telescopes with focal ratios between f/3 and f/6, and apertures ranging from 150 mm to 600 mm. Its design is ideally suited to astrophotographers using full-format sensors (44 mm image circle), guaranteeing sharp, round stars right up to the edges of the field.

Technical features and benefits

This model has a reduction factor of 1.0×, which means it retains the telescope's original focal ratio without altering it, while providing full coma correction. Thanks to its quadruplet design, including extra-low dispersion lenses, it effectively reduces aberrations and enhances image sharpness and clarity.

  • Application: Newtonian telescopes from 150 to 600 mm aperture, focal ratio f/3 to f/6
  • Reduction factor : 1.0× (no change in focal ratio)
  • Image circle : 44 mm, ideal for full-frame sensors
  • Lens design : Quadruplet with extra-low dispersion lenses for optimum aberration correction
  • Outside diameter : 50.8 mm (2 inches), compatible with most 2-inch eyepiece holders
  • Back-focus : 55 mm (distance measured from end of baffle ring to focal plane)
  • Total length : 118.7 mm
  • Coating : Multi-layered over the entire surface for maximum light transmission
  • Weight : 0.35 kg

Why choose the Sharpstar 2" 1.0× Coma Corrector?

The Sharpstar 1.0× coma corrector is perfect for astronomers using large-aperture Newtonian telescopes who wish to correct coma without changing the focal length of their instrument. With its robust construction and advanced optical design, this corrector guarantees high-quality images with well-defined stars across the entire field. Easy to connect thanks to its standard 2" design, it is compatible with a wide range of accessories and imaging equipment.

In short, the Sharpstar 2" 1.0× Coma Corrector is an essential accessory for serious astrophotographers looking to maximize the quality of their images with Newtonian telescopes, maintaining the original focal ratio while optimizing the sharpness of stars right to the edges of the field of view.
