SM Astro V4 RASA 8 Diffraction Mask & Cable Router

SM Astro RASA 8 Diffraction Mask & Cable Router (V4)

Achieve picture-perfect stars while taming unruly cables. This custom-engineered mask for the Celestron RASA 8 neatly routes your camera cables to eliminate messy, asymmetrical artifacts in your images, replacing them with clean, classic diffraction spikes.

Key Features:

• Dual-Purpose Design: Keeps your cables securely anchored while adding creative, crisp diffraction spikes to your stars.

• Universal Camera Fit: Engineered to seamlessly accommodate all camera bodies.

• Dew System Ready: Fully compatible with the Celestron Dew Heater Ring.

• Engineering-Grade Material: 3D printed in Matte Black Glass-Fiber Reinforced ABS (ABS-GF). This provides exceptional rigidity and thermal stability, ensuring zero flexure during those long, multi-night imaging runs.

• Ultra-Lightweight: Adds a mere 50 grams to your front-end assembly.

• Anti-Reflective Finish: The ABS-GF provides a superb matte black finish straight off the printer to minimize stray light. It also readily accepts flat-black paint or flocking if you want to darken it further.

Important Note for Filter Drawer Users: To maintain a precise and secure fit, the V4 mask sits close to the imaging train. If you are using a filter system like the Starizona Filter Slider, the mask restricts drawer removal. You will simply need to shift or lift the mask slightly to swap filters. This is a quick adjustment and poses no inconvenience if you typically shoot one filter per session.
