Daystar Filters Interference Eliminator - 2" to C Mount

  • Innovative Solution for Interference: Specifically designed to tackle the common issue of interference fringes, patterns, or Newton's Rings in monochromatic light imaging, particularly Hydrogen Alpha.
  • Camera Tilt Mechanism: Utilizes a unique tilting action to shift the camera off-normal, maintaining the image sensor's center stationary. This ensures focus, framing, and vignetting remain unaffected.
  • Optical Path Adjustment: By altering the angle of incidence and optical path lengths inside the image sensor, it effectively mitigates interference without impacting image quality.
  • Easy Installation: Designed for direct placement in front of the camera in the optical train. Ensures a specific distance of 17.5mm from the male C thread flange to the camera's focal plane for optimal performance.
  • Spacer Requirement for CS Mount Cameras: Requires a 5mm spacer for CS mount cameras to achieve the best effect, while C mount cameras need no spacers.
  • Simple Usage Process: Adjustable by loosening thumbscrews and sliding the two halves apart to achieve the desired tilt, minimizing interference patterns.
  • Fine Tuning Capability: Offers the ability to adjust the tilt minimally to eliminate fringes, essential in fast focal ratio systems to avoid focus loss at the image's top and bottom.
  • Directional Adjustment Options: If the maximum tilt in one direction is ineffective, the device can be fully tilted in the opposite direction for better results.
  • Reduction in Severe Cases: In extreme cases, it might not completely remove the interference pattern, but significantly reduces it to a level manageable by flatfielding or compositing techniques.
