Astronomik ProPlanet 642 BP IR-Pass Filter - Sony Alpha 7 Clip

Astronomik's most recent contribution to their ProPlanet IR-Pass line of filters, the ProPlanet 642 BP offers an extensive range of daytime IR imaging applications, along with high resolution lunar and planetary imaging, and capturing spectacular photos of objects in the H-Alpha portion of spectrum when employed for astrophotography.

This filter provides a 200 nm spectral window from 642 nm to 842 nm. Unlike Astronomik's other two ProPlanet filters, the P642 blocks the longer infrared. Along with the ProPlanet 742 and 807 filters, Astronomik now gives you three choices for your IR-imaging needs. The ProPlanet 642 will frequently be the correct choice for optimal imaging.

Daylight IR-Imaging:

  • High contrast images with excellent color rendition
  • Clear images with "wood effect"
  • No hot spot from longer IR
  • Short exposure times analogous to regular VIS-imaging
  • Ideally suited for Infrared videos

High Resolution Lunar & Planetary Imaging:

  • Short exposure times
  • Effective reduction in seeing
  • Improved contrast
  • Longer IR is blocked to remove ghosting and facilitate maximum sharpness

Deep-Sky Astrophotography of H-Alpha Regions:

  • Best transmission of H-alpha line at 656 nm
  • Close to 40 nm FWHM with DSLR cameras that have been astro-modified
  • Incredible contrast in moonlight or light polluted conditions
  • Sensible pricing for casual H-Alpha imagers
  • Camera display plus LiveView provides simple focusing

Technical Specifications

  • 96%+ transmission for 642 nm to 842 nm wavelengths
  • Blocks wavelengths in the 350 nm to 630 nm range
  • Parfocal with all other filters made by Astronomik
  • Glass thickness: 1 mm
  • Fully protected from the impacts of scratching, aging, and high humidity
  • Diffraction limited, this filter will not reduce your telescope's optical performance
  • Astronomik filters come with a long-lasting, high quality plastic storage case
  • German-designed for superior optical quality!

Astronomik Sony Alpha 7 Clip Filter System

Astronomik's patented Clip-Filter system has been designed from black anodized aluminum and laser-cut on up-to-date modernized machines. Within seconds, it can be introduced directly into the body of a Sony Alpha 7 models 7, 7r, and 7s in MkI, MkII, and MkIII versions respectively. No adjustments are required and all lens functions like focus, screen, and image stabilization, remain operational! This Clip-Filter system also serves as an effective dust protector, keeping dust from collecting on the sensor during extended exposures.
