The L-Pro filter, which prevents the passage of artificial stray light, has five pass bands, located in those regions of the visible spectrum in which astronomical objects emit, and has received a highly positive response from amateur astronomers and astrophotographers.

Filter Optolong L-Pro broadband anti-light pollution filter EOS-C

Product description

The L-pro filter has five transmission bands (the most of any anti-pollution filter on the market), covering more of the visible spectrum to provide more realistic colors. The transmission windows coincide with the OIII, Hbeta, NII, Halfa and SII wavelengths (and other windows where there are no spectral emissions from sodium vapor or mercury vapor bulbs), so the L-pro can be considered a multi-window nebular filter. Its filter factor is 1.5 (1.5 times more exposure time than without filter). As a filter that is not overly restrictive, it is the optimal filter for areas with medium light pollution.

The filter is made of optical glass with a flatness level of λ / 4 on both surfaces (the surface irregularities are

The L-Pro has an ultra-clean substrate after passing through 13 ultrasonic and purified water cleaning tanks to effectively remove any remaining impurities and dust.

Its outermost coating with ion-assisted electron beam evaporation deposition technology provides enhanced durability and scratch resistance, as well as CWL (center wavelength) stability unaffected by temperature changes.

All L-Pro undergoes extensive quality control: each filter is individually tested with spectrophotometer and laser interferometer to ensure that its output spectrum and wavelength front is adequate.

Technical specifications:

  • Peak transmission: T > 90%
  • Spectral range: 380-750 nm
  • Optical density: 90% blocking of light pollution
  • Filter factor: 1.5 (1.5 times more exposure required than without filter)
  • Spectral windows of astronomical interest: OIII, Hbeta, NII, Halfa and SII
  • Surface quality: 60/40
  • RMS of transmitted wavefront: λ / 4
  • Parallelism (arcsec): 30"
  • Format: Clip
  • Size: EOS-C (Canon APS-C)

COMPATIBILITY:

Clip-Filter -C format is compatible with the following Canon EOS APS-C models: Canon Digital Rebel XS / Digital Rebel XSi / / EOS 1000D / EOS 500D / EOS Kiss F / EOS Kiss X2 / EOS Kiss X3 / EOS Rebel T1i / EOS 6D / EOS 60D + 60Da / EOS 7D / EOS 70D / EOS 50D / EOS 650D / EOS 600D / EOS 550D / EOS 700D / EOS 1100D / EOS 1200D / EOS 40D / EOS 30D / EOS 20D / EOS 10D

Being compatible with all EF type lenses.
Clip-on filters are not compatible with EF-S lenses for APS-C cameras, because the filter occupies the space where the back of the lens is housed.
