Back to 350 D - M 42
My 3350D hasn't IR filter. I try to test about the noise in red channel. My 1100D is present much noise.
Without the IR filter I have less noise, but I loose some green and blue color. (I am wondering if atmosphere and IR filter are causing this amount of noise)
photo 1: final result
photo 2: the RAW crop
photo 3: the DSS result crop
photo 4: Halfa red channel only.
note: the result of DSS is very red. I will try to stack again with no Bias. I can not see the reason to this reddish appearance.
oh, I forgot: it was only test of camera and BackyardEos remote control. Only 6 x 1 min ISO 400 RGB Skyglow filter and 10 x 3 min ISO 400 Halfa filter.
