Permanently eliminate distracting diffraction spikes on your stars and recover maximum contrast. The Carbon-Fiber PETG corrector mask for Sky-Watcher Newtonians.
Enhance contrast and pinpoint stars for Sky-Watcher Newtonian Telescopes
Newtonian reflector users know the struggle: the stock metal spider vanes create four massive light spikes across bright stars. While some enjoy this look, these diffraction spikes actually swallow subtle deep-sky details (faint background galaxies, nebula tendrils) and scatter stray light, dropping your planetary contrast. Our carbon-fiber diffraction mask solves this at the source.
⚙️ Snug Snap-On Tension FitEngineered to be simple and safe, this mask features a toolless mechanical pinch lock. It slides directly over your stock spider vanes. Setup takes seconds, uses zero screws, and keeps your optical collimation perfectly intact. |
💎 Rigid Carbon-Fiber PETGPrinted with carbon-fiber reinforced PETG, this accessory yields an elite strength-to-thickness ratio. The profiles stay incredibly thin to avoid blocking primary light while breaking up the harsh diffraction lines without dew sagging. |
To keep things easy, we grouped the most popular factory sizes in a single page. Simply choose your aperture from the dropdown option menu:
• Sky-Watcher 150 mm Model (150/750, etc.)
• Sky-Watcher 200 mm Model (200/1000, Quattro 8-S, etc.)
• Sky-Watcher 250 mm Model (250/1200, Quattro 10-S, etc.)
• Artesky Vanes: If you upgraded your stock spider to an Artesky model, your vane thickness differs from the factory build. You must leave a note during checkout detailing your precise branch thickness so we can adjust the internal tension slot width.
• Custom Bespoke Models: Running a GSO, Orion, TS-Optics, or a custom DIY build? We can manufacture your mask completely custom to order. Contact us before ordering to share your dimensions.
💡 The Astronomer's Advice: "Harsh diffraction spikes quickly saturate the cores of bright stars, which complicates star reduction steps during image processing (in PixInsight or SiriL). Slipping this Carbon PETG profile onto your spider beautifully blends that light energy. Stars stay tight and round, and your dynamic background details pop instantly."
