A better* Milky Way Core picture


ELS

Recommended Posts

Stacked 100x13" exposures @ ISO3000, F3.5, 18mm. using DSS.
The amp and driver noise is incredible, really shows the 400D's age. DSS for some reason didn't properly frame the final image and cut off a lot of it. I was kinda relying on the sky movement to get a wider shot (I pointed the camera vertically)
Apparently with enough exposures stacked together the banding cancels out quite a lot. So perhaps that's an advantage of stacked exposures over longer ones.

If your image was expected to be wider then you could try; 

Break your 100 images into four stacks of 25

Stack each 25 and then process 

Stitch your four finished images together

Nevermind that, I was expecting it to be much more, but it is about right.

I tried adding flats, darks, biases, dark flats. And it seems to give me a less noisy result, but it's even worse in the vignetting. And I still cant get the colors right.
What I think is happening is that the noise gets amplified and since there are twice as many green channels, it looks as if the white balance is off, when it actually is not. I don't really know how I could fix that, I guess raising the black level on the green channel more but it doesn't seem to work like I was expecting it to.
And the vignetting might just be that my flats aren't right. idk.
I'll try to see if I can process chroma and luma separately so that the fainter features, if the noise is too bad get turned to BnW instead of green.
I attached the TIFF unprocessed master. another try with calibration.TIF
