Wow! Is it an uncropped image? If that is the case, ur APO really sharp to corner and without obvious vignetting!
PS* I suppose u didn't do any DBE like processing.

[benben88]

It is a cropped image (cropped around 10%) as I didn't do any flat field. You know canon camera has annoying shadow of mirror casting on the sensor ,and flat field is a must. There is minimal vignetting at the extreme corner, may be due to the camera ring (48mm still no big enough for FF) .
BTW, It is just a test shot for my Dell tablet. [微笑]

十秒都咁多細節，這個CCD 幾靈敏啊。

Very low noise

八八卦卦睇過個CCD嘅技術規格，似乎係深空利器喎，比起SBIG，價錢差唔多（咁貴）
