During last 1 year, we have found that 1100D image sensor’s background noise levels are so various.
Some are good as that of 600D but others are so poor. We thought his unstable sensor quality is not suitable for astro imaging usage and we decided to discontinue the modification of eos 1100D.
Instead of CDS-1100D within several months, we are to release several CDS- models based on Canon’s new DSLR models.
Thank you.
Now we are studying to release cooled 5D MarkIII.
Below images the prototype design of it and be possible to be changed.
The images were taken at indoor dark room (Temperature : 20C~22C) and the exposure time was 450sec ( 7.5 minutes).We croped 224×224 pixels in center area of original images and not resized.
In order to distinguish the deferance of each shots more easily we stretched the tone levels in Photoshop program. The default value of highlight Levels is 255 and we stretched this to 30Levels. Read more
We compared the dark frame shots of unmodified camera and cooling modified camera and the models are EOS 1100D(= Rebel T3, Kiss X50 ) and CDS-1100D / EOS 600D (=Rebel T3i, Kiss X5) and CDS-600D / EOS 60D and Astro60D.The images were taken at indoor dark room and the exposure time was 450sec ( 7.5 minutes).We croped 224×224 pixels in center area of original images and not resized.
