  • Starlight Instruments 2.0" Base Curved w/ Leveling Screws for Vixen R200SS OTA

    This custom-machined Starlight Instruments base is the essential component for upgrading your Vixen R200SS OTA with a high-precision 2.0" Feather Touch focuser, providing a rock-solid, perfectly curved mounting surface for demanding imaging applications.

    A Precision-Machined Base for the 2.0" Feather Touch on Your Vixen R200SS

    The stock focuser on many telescopes is a common point of mechanical flexure, especially under the weight of a heavy camera. This Starlight Instruments base is the first step in a critical upgrade, replacing the original hardware with a solid aluminum platform custom-machined to match the exact curvature of the Vixen R200SS tube. This ensures a flush, stable fit without gaps, creating the ideal foundation for a 2.0" Feather Touch focuser.

    For a fast Newtonian astrograph like the R200SS, precise alignment of the focuser is not optional—it's essential for achieving sharp stars across the field. This base includes integrated leveling screws, allowing you to collimate the focuser drawtube perfectly perpendicular to the optical axis. This adjustment capability is crucial for eliminating image tilt and ensuring your coma corrector and camera sensor are positioned optimally.

  • Will this Starlight Instruments base fit any 2.0" Feather Touch focuser?

    Yes, this base is designed to accept any standard Starlight Instruments 2.0" Feather Touch focuser, allowing you to choose the model that best suits your imaging or visual needs.

    Why do I need this specific curved base for my Vixen R200SS?

    The base is custom-machined to the specific outer diameter of the Vixen R200SS optical tube. This precise curvature ensures a solid, flush mount that prevents instability, gaps, or flexure that could occur with a generic flat base.

    What is the purpose of the leveling screws on the Starlight Instruments R200SS base?

    The leveling screws allow you to make fine adjustments to the tilt of the entire focuser assembly. This is a critical step in collimation, ensuring the focuser's mechanical axis is perfectly aligned with the telescope's optical axis. Proper alignment is essential for sharp, coma-free images, especially with the fast optics of the R200SS.

    Is this base compatible with other Vixen telescopes besides the R200SS?

    No. This base is specifically designed and machined for the tube curvature of the Vixen R200SS OTA. It will not fit other models correctly.

    Can I install this Starlight Instruments base on my Vixen R200SS myself?

    Yes, installation is straightforward for users comfortable with basic tool usage. It typically involves unbolting the stock focuser and attaching the new base, often using the telescope's existing mounting holes. You will need to perform a full collimation of the telescope's optics after installation.

    I want to use a heavy imaging camera on my Vixen R200SS; is this base strong enough?

    Absolutely. This base, when paired with a 2.0" Feather Touch focuser, creates an extremely rigid and stable focusing system. It is designed specifically to eliminate flexure and support the weight of modern cooled astronomy cameras, filter wheels, and other accessories.
