Wanderer Ultimate Cable Master for RASA or HyperStar 6 - Spike-Free Version - WUCMR6-SF

Eliminate Cable-Induced Diffraction Spikes

After dozens of design iterations and extensive testing, WandererAstro developed a spike-free design with an S-shaped PCB that is only 3–4 mm wide. RASA and HyperStar systems can now produce refractor-like, spike-free star images.

This model is designed specifically for the Celestron 6" RASA or scopes with the HyperStar 6 installed.  It is the Spike-Free version.  See below for a short explanation about why you might choose the Spike Free over the Cross Spike version of the Wanderer Astro Ultimate Cable Master.

Patented Design Eliminates Cables

A specially designed PCB spans the optical path, completely eliminating the need for cables in the light path. The result is cleaner diffraction patterns and improved image quality, addressing one of the most common challenges faced by RASA and HyperStar users.

Multiple USB and Power Ports

RASA/HyperStar 6/8 models include two USB 2.0 ports and one 12V power port. The 12V port supports up to 3A; for continuous use, 2A or less is recommended (85% camera cooling power or below).

RASA 11/36 and HyperStar 11/14 models feature one USB 3.0 port, one USB 2.0 port, and one 12V power.

Compatible with Dew Shield and Heater

The bracket uses a non-destructive installation design and is fully compatible with the original Celestron dew shield and most third-party dew shields, as well as the original Celestron dew heater ring.

Two bracket lengths are included to support different camera body lengths and the differing back-focus requirements of RASA and HyperStar systems. Short USB and DC cables are also included.

Should You Choose Cross Spike or Spike-Free?

From an optical standpoint, the Cross Spike Version introduces minimal obstruction and can deliver slightly sharper images.

If you do not like diffraction spikes, or if you need to rotate the CAA very often, the Spike-Free Version is the better choice. However, unlike a refractor, residual diffraction artifacts may still be visible in bright stars due to factors such as stress in the Schmidt corrector plate, although the results are significantly cleaner than with traditional solutions.
