    Does anyone know of a UK company that will replace the sensor filter on a dSLR to suit it for astro-photography. I assume that it is a similar operation to converting for IR although, for astro work, we need to retain the sensitivity to the visible spectrum while extending it a bit beyond 700nm.

    Basically I want to get an old Nikon D70 converted to act like the custom-built Canon EOS 20Da.

    There was a firm called ACS that did IR conversion work but they seem to have gone belly-up as they don't respond to e-mails.

    Any ideas?

    Interesting.

    I was considering sending my trusty D70 off to them for conversion... Sad

    Why not contact their nemesis in the US - Life Pixel and get their input?

    Check this site, the guy gave a brilliant lecture with awesome pics at our local camera club, He used a Nikon d200 with 200mm lenses may be of some use, don't recall he had to modify camera but he used a neat gismo on the tripod to track stellar movement

    Remove it yourself, then use external filters to get halpha sensitivity.

    They are quite easy to do, you just need the right thickness screw driver - makes it a doddle.

    Generally nikons are quite easy to remove parts from; compared to point and shoots an canon - which tend to use more film-like IR cut offs.

    - Make sure you do this in a positive pressure environment, dust is a big problem.

    Some on SGL use Astronomiser, but quite a few go DIY SGL. Either way there will be plenty of help and advice there.

    I had my old D10 converted using Astronomiser, works a treat and at a reasonable price.
