Hi Everyone,
A little while ago the question was asked about how dark the Central DS1100 Darks really were? JJJ did a comparison of her 550D to the CDS-100D camera here is the thread:

I thought I would do a more direct comparison as I have just taken receipt of my Central DS CDS-600D and I also have a standard non modified in any way EOS 600D Camera. so I am comparing apples directly to the same apples.
I have done two tests: one at ISO 1600 and the other at ISO 400 both for 10 minutes, the Central DS Camera had the cooler running naturally and the Standard 600D Camera was just that! running standard, the ambient temperature was the same for both tests as I had the Air Con running at 23'C so the house could be considered a constant.
I have taken the images and blown them up to 200% and taken a copy and pasted them side by side for comparison and labelled accordingly.
One thing not so obvious is the temp increase on the standard camera, I did the ISO1600 and then straight away the ISO 400 tests on a camera so the ISO 400 shot was after the camera had been running for 10 minutes already, the temp sensor in the Central DS Camera added only 1'C after 20 minutes continuous exposing, the EOS 600D added 7'C after the 20 minutes exposure time.
Anyway I think the images attached speak for themselves, I was very please to see the difference and cannot wait to get the camera under the sky and take some images.
Cheers
Anthony
