  • Starlight Instruments SIPS Coma Corrector

    The Starlight Instruments SIPS (Starlight Integrated Paracorr System) combines Tele Vue's benchmark Paracorr Type 2 optics with a custom Starlight Instruments housing, creating the ultimate fixed coma corrector for fast Newtonian telescopes. Designed for the 2" Feather Touch focuser with 1.5" of draw tube travel, this system locks the corrector at the perfect optical distance, eliminating adjustment errors and mechanical flexure entirely.

    The Optical Core: An Integrated Tele Vue Paracorr Type 2

    At the heart of the SIPS are the legendary Tele Vue Paracorr Type 2 optics. This lens group is the industry standard for correcting coma, the optical aberration in fast parabolic mirrors that renders stars at the edge of the field as distracting, comet-like shapes. By integrating these world-class optics, the SIPS ensures that your f/3 to f/5 Newtonian delivers pinpoint stars across the entire field of view, from the center to the extreme edge.

    The Mechanical Advantage: A Fixed System for the 2" Feather Touch Focuser

    The true innovation of the SIPS is its mechanical design. Instead of a sliding, adjustable mechanism, Starlight Instruments has fixed the Paracorr Type 2 optics inside a rigid housing made specifically for their 2" Feather Touch focuser. This set-and-forget system means that once installed, the corrector is always at the optimal spacing, delivering perfect correction without any user intervention. You simply focus your eyepiece or camera, saving valuable time and eliminating a common source of setup frustration.

    SIPS vs. Standard Paracorr: Eliminating Flexure and Adjustment Hassles

    While a standard, tunable Paracorr offers the flexibility to be used in various focusers, that adjustability introduces complexity and potential flexure. The SIPS is a dedicated solution that trades universal compatibility for absolute performance and ease of use on its target instrument.

    • Zero Readjustment: With a standard Paracorr, you must fine-tune the corrector's position for different eyepieces. The SIPS requires no such adjustment; you just focus the focuser, making eyepiece swaps fast and foolproof.
    • Reduced Flexure: By creating a single, rigid unit, the SIPS provides a much more solid connection to the imaging train than a corrector held in place by thumbscrews. This is critical for astrophotography, where any amount of tilt or flex can compromise star shapes.

  • What problem does the Starlight Instruments SIPS solve?

    The SIPS solves the problem of coma in fast Newtonian reflectors while also eliminating the mechanical flexure and adjustment hassles of traditional, non-integrated coma correctors. It provides a rigid, set-and-forget solution for achieving perfectly round stars across the entire field of view, especially for astrophotography.

    Which focuser is the SIPS compatible with?

    The Starlight Instruments SIPS is specifically designed to be used with a 2" Feather Touch focuser that has 1.5" of draw tube travel. It is not compatible with other focuser models or brands.

    Can I use the SIPS for imaging deep-sky objects like the Orion Nebula (M42)?

    Yes, the SIPS is ideal for imaging objects like the Orion Nebula (M42) with a fast Newtonian. Its rigid, flex-free design ensures that the heavy cameras often used for deep-sky imaging are held securely, preventing tilt and maintaining sharp stars across the entire frame.

    Do I need to adjust the SIPS when switching from a low-power eyepiece to a high-power one for viewing Jupiter?

    No. This is the primary advantage of the SIPS. The optical corrector is fixed at the optimal position. When you switch from a wide-field eyepiece to a high-power planetary eyepiece to view Jupiter, you only need to adjust the main focus knobs on your Feather Touch focuser. The coma correction remains perfect without any further adjustments.

    How does the SIPS compare to a standard, adjustable Tele Vue Paracorr Type 2?

    A standard Paracorr is more versatile, as it can be used in any 2" focuser. However, the SIPS provides superior mechanical stability and ease of use. By fixing the optics, the SIPS eliminates a potential source of flexure and removes the need to constantly re-tune the corrector's position, saving you time and ensuring optimal performance every session.

    How do I collimate my telescope with the SIPS installed?

    The SIPS is designed to allow for easy collimation. The Tele Vue Paracorr Type 2 lens group can be removed from the main housing, giving you unobstructed access to your primary mirror for precise collimation adjustments. Once collimation is complete, you simply reinstall the lens group.
