Diffraction Spike Masks Duo (4 & 6 Spikes) — ZWO Seestar S50

Ultra-rigid Carbon-Fiber PETG composite, protective storage box & 100% safe auto-park

Due to its refractor lens design, the ZWO Seestar S50 naturally captures round, clean stars. While optically pure, star-dense fields, open clusters (such as the Pleiades), and bright guide stars can sometimes appear flat. This mask duo produces genuine optical diffraction spikes right at the focal plane, eliminating the need for synthetic software plugins.

✨ Two Geometric Spikes for Your Astro Compositions

🌟 4-Spike Mask (Classic Reflector)

Replicates the iconic aesthetic of Newtonian spiders or the Hubble Space Telescope. The four orthogonal spikes deliver balanced visual depth across bright background stars.

✨ 6-Spike Mask (Brilliant Asterism)

Generates an intricate six-pointed burst, adding dynamic flare to emission nebulae, rich star-forming regions, and open clusters.

The Structural Demands of Carbon-Fiber PETG

To keep light obstruction below 2% of the objective area, diffraction vanes must be thin while remaining straight. On common PLA prints, thin vanes easily sag under humidity or heat, creating blurred or split spikes. To manufacture these masks, I selected Carbon-Fiber reinforced PETG (PETG-CF):

  • Mechanical Rigidity: Dispersed carbon microfibers eliminate vane flex and flutter in nocturnal breezes.
  • Needle-Sharp Spikes: Geometric accuracy ensures clean, straight diffraction rays across raw subs and live stacks.
  • Anti-Reflective Matte Finish: Native PETG-CF texture naturally absorbs stray light near the edge of the frame.
🔄 Full Auto-Park Safety & Dedicated Storage Box:

As with all my Seestar S50 hardware, the low-profile contour maintains clearance for the rotating arm. At shutdown, the arm returns to its resting position and docks into the original foam case without mechanical strain on internal gear trains. To keep the second mask protected in your gear bag, I include a dedicated compact storage box.

📋 Field Usage Steps:

  1. Select your preferred spike pattern (4 or 6 vanes) and gently snap the mask onto the Seestar S50 objective.
  2. Point toward your selected target (open clusters, nebulae containing bright foreground stars).
  3. Run your standard live-stacking session: diffraction rays develop naturally over your integration.
  4. Store the second mask in its protective box to keep the thin vanes straight and dust-free.

💡 The craftsman's word: "Diffraction spikes add distinct visual presence to nebulae and open clusters. By 3D printing these masks in Carbon PETG in my Cannes workshop, I achieve vane stiffness that regular PLA simply cannot provide, yielding clean spikes on every exposure. All offered at a direct price of €12.90 for both masks with storage box."

❓ Frequently Asked Questions (FAQ) — Seestar S50 Diffraction Duo

🔹 Can real quality be expected at just €12.90 for two masks and a box?

Yes, without compromise. Accessible pricing at Azur3dprint does not mean substandard work. Where others sell single PLA masks at inflated prices, I offer fair pricing for two units 3D printed in Carbon-Fiber reinforced PETG to keep thin vanes rigid, complete with their storage box. Real craftsmanship at an honest price.

🔹 Why use Carbon PETG over basic 3D printing filament?

Diffraction mask vanes must remain narrow yet straight. Standard PLA sags easily, flutters in the breeze, and warps with temperature shifts. Carbon-reinforced PETG provides the structural rigidity needed to keep vanes straight, preventing split or fuzzy diffraction spikes.

🔹 What happens if I forget to remove the mask during auto-park?

Zero mechanical risk. I designed these masks to preserve the native operating envelope: the telescope arm rotates and parks without contacting the chassis, protecting drive motors and belts.

🔹 Do these masks reduce light gathered by the Seestar?

Obstruction from the thin vanes accounts for under 2% of the total 50 mm objective area. Deep-sky light throughput remains essentially unaffected, while stars gain immediate visual presence.
