That's a Sony CCD so I am no particularly familiar with it beyond the fact its the same sensor that I had in my Nikon D70 which was my first astro camera.

50% QE for a one shot colour seems either incredibly efficient compared to Kodak one shot colour CCDs which are apart from the latest True sense sensors all about 25-50% with the average being high 20's. Those 60-50% are better than a mono STL11 or comes close to matching a FLI Microline 8300.

I recall a comment by Peter Ward that Sony uses relative QE to measure their CCDs. Perhaps that is where the difference is or perhaps the chip is in fact that sensitive. I suspect the figures have been massaged for marketing reasons.

Regardless it sounds like an interesting chip and I'd love to see some more images coming from it.
