The Skywatcher 2" Coma Concealer is an essential optical accessory designed for Newtonian Reflector telescopes with a fast focal ratio f/5. This innovative device significantly improves image quality by correcting coma distortion, which can blur stars at the edges of the field. The Coma Concealer ensures sharp stars across the entire field, providing an excellent viewing experience without changing the magnification. This correction is ideal for visual observation and astrophotography. However, for astrophotography, an additional M48x0.75 adapter compatible with your DSLR camera brand (such as Canon or Nikon) is required and sold separately.

• Compatibility: Optimized for Sky-Watcher f/5 Newtonian Reflector telescopes and Dobsonians with a 2" focuser.
• Optical Correction: Corrects coma distortion for sharp stars across the entire field, enhancing star images.
• Magnification: Maintains the natural magnification of your telescope.
• Optical Use: Includes the necessary adapters for seamless visual observation.
• Astrophotography: Requires a separate M48x0.75 adapter for camera connections.
• Construction: Designed with a durable 2" barrel size, compatible with standard focusers.

In summary, this coma corrector is a crucial addition for anyone seeking high-quality, distortion-free views through fast Newtonian telescopes, especially for astrophotographers and enthusiastic observers.
