Seymour Solar Hyperion Thin-Film Slip-On Solar Filter – Telescope, Spotting Scope, and Camera Lens Accessory
Description
Capture and observe the Sun safely with the Hyperion Thin-Film Slip-On Solar Filter by Seymour Solar. This ND5 white-light filter uses our lightweight solar film to block 99.999% of sunlight while delivering a clean, detailed solar disk with a slightly darker orange image characteristic of premium ND5 film. Ideal for travel, eclipse viewing, and everyday solar observation.
Key Features
Hyperion ND5 Solar Film: Lightweight, portable, and provides excellent surface detail for both visual use and imaging.
ND5 Optical Density: Safe for direct solar viewing when mounted on the front of your optic.
Slip-On Aluminum Cell: USA-assembled, secure, and designed for consistent fitment across telescopes, spotters, and camera lenses.
Travel-Friendly: Perfect for eclipse chasers, outreach programs, and lightweight setups.
Compatible With: Any optic whose OD matches the supported size range.
What You’ll See
Sunspots and active region structure
Solar surface mottling and granulation
Eclipse silhouettes (partial and annular)
Planetary transits
Material Characteristics
Hyperion Film: Produces a slightly darker orange solar image compared to glass, with excellent visibility of sunspots and limb features. Film is extremely lightweight and ideal for travel or portable setups.
Sizing & Fit
The slip-on cell seats approximately 1 inch (25 mm) deep. Measure the outer diameter (OD) of your telescope, spotting scope, or camera lens—considering any flare or wider section within that first inch—and select the filter size whose OD range includes your measurement.
Hyperion ND5 film filters are for front-mounted solar use only. Not for use as eclipse glasses or directly by the eye without an optical instrument. Not certified under ISO 12312-2 (applicable only to eyewear). Always confirm a secure fit before pointing your optic toward the Sun.
FAQs
Is film safe? Yes — Hyperion ND5 film blocks 99.999% of sunlight when installed correctly.
Why choose film over glass? Film is lighter, more portable, and excellent for outreach, travel, and handheld imaging setups.
Can I use this on a camera? Yes — simply measure the lens barrel OD (not the thread size) to choose the correct variant.
