  1. May 22, 2024 · The groundbreaking infrared sensors use layers of repeating molecular structures to interact with individual photons, or units of light. The sensors resolve more wavelengths of infrared at a higher resolution: 260 feet (80 meters) per pixel from orbit compared to 1,000 to 3,000 feet (375 to 1,000 meters) possible with current thermal cameras.

    • Canon EOS 1000D DSLR. 4.0 out of 5 star rating. Price £199. The Canon EOS 1000D is an older model in camera terms, but as such it makes a great entry-level DSLR camera for those starting out in astrophotography.
    • Bresser full HD deep-sky camera. 4.0 out of 5 star rating. Price £231. The Bresser full HD is aimed capturing images of planets, the Moon and also some basic deep-sky imaging.
    • Altair GPCAM2 327C. 4.5 out of 5 star rating. Price £269. The GPCAM2 327C is simple to set up and get going, making it a good choice for those who need to make the most of gaps in clouds.
    • ZWO ASI224 high frame rate colour camera. 4.0 out of 5 star rating. Price £299. The IMX224 sensor in the ASI224 has excellent infrared sensitivity, which means it can be used for proper infrared imaging when a suitable infrared-pass filter is fitted, for example the bright planets.
  2. NIRISS — the Near-InfraRed Imager and Slitless Spectrograph. NIRISS is an innovative instrument that will support operations in three observing modes. It has a camera that will be usable in parallel with the NIRCam camera to provide additional imaging capabilities for Webb. It features a slitless spectrograph, where all the light falling on ...

  3. Infrared astronomy. Infrared astronomy is a sub-discipline of astronomy which specializes in the observation and analysis of astronomical objects using infrared (IR) radiation. The wavelength of infrared light ranges from 0.75 to 300 micrometers, and falls in between visible radiation, which ranges from 380 to 750 nanometers, and submillimeter ...

  4. Since then, the development of InGaAs, InSb, and HgCdTe detectors has facilitated ground-based observations in the J and H astronomical bands of the NIR-II / short-wavelength infrared (SWIR) range extending from 1050 nm to beyond 1700 nm. The J and H bands, which are depicted in Figure 1, correspond to 1100–1400 nm and 1500–1800 nm ...
