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.

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

Thanks Sam - I lost that link a while ago!!
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.

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