CDS-1100D discontinued.

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.

DarkFrame comparison :1100D,600D,60D,50D,40D

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. 자세히 보기

개조하지 않은 카메라와 냉각 개조된 카메라의 다크 프레임 촬영을 비교하였습니다.
모델은 EOS 1100D (= Rebel T3, Kiss X50)와 CD-1100D / EOS 600D (= Rebel T3i, Kiss X5)와 CD-600D / EOS 60D와 Astro60D입니다.
사진은 외부의 빛이 차단된 실내에서 촬영하고 노출 시간은 450sec (7.5 분)입니다.
