What is an astro modified DSLR camera and how does it help astrophotography?

Astro modified cameras are regular DSLRs where part of the infrared (IR) filter has been removed to allow it to processes color from deep-sky objects better.

Specifically, this makes it more capable of capturing images of nebulae by better capturing the Hydrogen Alpha spectral line (656nm) – this is the precise color emitted by hot clouds of Hydrogen gas that occur in emission nebulae.

Regular DSLRs are not designed to be sensitive to this wavelength, but with modification of the IR filter, they can be.

How to get an infrared converted camera for astrophotography?

There are three ways to get an astro modified camera:

  3. Perform the modification yourself on your own camera

    • You can purchase a Astronomik OWB Filter – Type 3 that will restore the ability of the camera to be used for terrestrial photography, like the original standard equipment filter
