  • Daystar Interference Eliminator - C mount

    The Daystar Interference Eliminator for C-mount cameras is the definitive solution for removing the wavy interference fringes, often called Newton's Rings, from your monochromatic images. Designed for long focal ratio systems common in Hydrogen-alpha solar imaging, it introduces a precise, adjustable tilt to the camera sensor to cancel the internal reflections that cause these distracting patterns without altering your image's focus or framing.

    Eliminate Newton's Rings with Precision Tilt Control

    When imaging in monochromatic light with long focal ratio instruments, nearly parallel light rays can reflect between the surfaces of your camera's sensor and its cover glass. This creates an interference pattern of light and dark bands that can ruin an otherwise perfect image. The Interference Eliminator solves this by introducing a controlled tilt to the sensor, which changes the optical path length and angle of incidence, effectively mitigating the interference.

    Adjustment is straightforward: by loosening two thumbscrews, you can slide the two halves of the unit to apply the minimum tilt necessary to make the fringes disappear. While it can resolve even severe patterns, be aware that excessive tilt in fast optical systems can cause some loss of focus at the image edges, so minimal adjustment is key.

    C-Mount Integration Without Shifting Your Frame

    Unlike crude solutions like shimming, the Daystar Interference Eliminator is engineered to tilt the camera while keeping the geometric center of the sensor stationary. This critical design feature ensures that as you make adjustments, your image framing, focus position, and vignetting profile remain unchanged. You can dial in the perfect amount of tilt without having to constantly re-center your target.

    • Native C-Mount Support: The Eliminator threads directly onto any C-mount camera, providing the exact spacing required for optimal performance without any additional adapters.
    • CS-Mount Compatible: For cameras using the CS-mount standard, adding a simple spacer places the sensor at the correct distance for the tilt mechanism to work as designed.
    • Robust Construction: The entire unit is CNC machined from aluminum, ensuring a rigid, flex-free connection in your imaging train that maintains perfect alignment.

  • What problem does the Daystar Interference Eliminator solve?

    The Daystar Interference Eliminator is designed to remove interference patterns (Newton's Rings) from images. These are wavy light and dark lines that often appear in monochromatic imaging, especially in long focal ratio systems like solar telescopes, due to internal reflections within the camera sensor.

    How do I adjust the Daystar Interference Eliminator?

    To adjust the unit, slightly loosen the thumbscrews and slide the two halves of the device apart. This action tilts the camera. You should take test images as you adjust, applying the minimum amount of tilt needed to make the interference pattern disappear. Once the pattern is gone, re-tighten the thumbscrews.

    Will the Daystar Interference Eliminator change my telescope's focus point?

    No. A key feature of the Daystar Interference Eliminator is that it tilts the camera sensor around its physical center. This means that adjusting the tilt will not shift your focus point, change image framing, or introduce vignetting, making it far superior to manually shimming a camera.

    I'm seeing wavy lines on my solar images with a DayStar Quark filter and a C-mount camera. Will the Interference Eliminator help?

    Yes, this is precisely the scenario the Daystar Interference Eliminator was designed for. The long effective focal ratio created by a DayStar filter is a common cause of interference fringes. This device will allow you to tilt your C-mount camera to eliminate those patterns for a clean, professional-looking solar image.

    Can I use the Daystar Interference Eliminator on my fast f/5 Newtonian for H-alpha imaging?

    While it might help, it is primarily recommended for long focal ratio (slow) systems. In fast systems like an f/5 Newtonian, the light rays approach the sensor at steeper angles. Tilting the sensor in such a system can lead to noticeable loss of focus at the top and bottom of the image frame, so it may not be the ideal solution.

    Do I need any adapters to use the Daystar Interference Eliminator with my CS-mount camera?

    Yes. While the Daystar Interference Eliminator connects directly to C-mount cameras, a CS-mount camera will require a 5mm spacer. This spacer ensures the camera's sensor is positioned at the correct distance from the tilt mechanism for it to function properly without shifting the image frame.
