STC Astro-Multispectra Clip Filter for Panasonic bodies is a novel light pollution filter designed by STC Optics with transmission characteristics designed by professional astronomer and renowned astrophotographer Dr. Wei-Hao Wang. Check out the comparisons below to see how effective the Astro-Multispectra filter is!
Placing the light pollution filter closer to the sensor reduces color shift that may occur at the peripheral areas of the image if front screw-in lens filter is used.
Highlights
- Greatly reduces interference from artificial lighting in city
- Suitable for all Panasonic M43 & Blackmagic cameras*
- Natural colour representation
- High transmission for astronomical bodies emission
- Co-developed by STC and Dr. Wei-Hao Wang, a professional astronomer and renowned astrophotographer
* Please refer to compatible camera list below
Features
- Clip Filter is designed for Panasonic & Blackmagic cameras. Mounting and removing the Clip-Filter is quick and easy. The colour shift problem that may occur due to the wide angle SLR lens in peripheral areas of the image could be reduced. The recommended lenses focal length is 14mm or longer
- The material is A2 stainless steel which is virtually non-magnetic and less brittle at low temperatures. Specially designed Clip-shaped structure could be pressed firmly while attaching the lens on camera body.
- STC Astro-MS Clip filter can reduce the interference from artificial lighting in the city, and enhance the wavelength of Hα, Hβ, OIII and SII. (Hα=656.3 nm, Hβ=486.1 nm, OIII=495.9 & 500.7 nm, SII=672.4 nm)
- It is coated by the use of the IBAD (Ion beam-assisted deposition) technology on Schott® B270 optical 2mm glass, working for higher durability and easily cleaning, and preventing aging variation in optical spectral characteristics due to temperature and humidity change
- High-quality double-sided NANO Anti-smudge coating provides excellent performance on waterproof and grease-proof capability
- Considering the different optical lens properties of all kinds of brands, it is normal for spherical and coma aberration to occur on part of the fisheye lens, super wide angle lens and wide angle lens.
- 12 months' original manufacturer warranty and lifetime warranty on aluminium frame

STC Astro-M Transmission Characteristics
- Natural colour representation by selectively blocking out UV light below 410nm, sky glow in between 620nm and 640nm and infrared light beyond 680nm
- High transmission for astronomical bodies emission at Hα=656.3 nm, Hβ=486.1 nm, OIII=495.9 & 500.7 nm, SII=672.4 nm and slightly passing yellow-orange-ish emission at 605nm.
STC Technologies
STC utilises ion beam assisted deposition (IBAD) to solidly bind the coatings onto Schott B270 glass, the very same glass used in Zeiss lenses. Such technique enhances the light transmission and also durability of the 160 layers of coating deposited to produce the advanced filter characteristics shown above.
With patented Ultra Layer® technology, both surfaces of Astro-Multispectra are coated with Anti-Smudge nano-coating to prevent dust and water from settling on the filter surface. Dew will not form and your filter is always clean. If necessary, it's effortless to clean.
Warranty
6 months' warranty covering defects due to manufacturing and workmanship
Extended to 12 months by registering on STC website.
