And about as good as I can get it withough spending a lot of time on it. 

Its good data but but, for my taste, the galaxy is just too far away. I am used to working with focal length of 2800mm on my C11.

Dark Flats in BPP.

Looks like you add them to the Flats section and it uses them separately.

Hi Mark

I did that he first time around, but it gave me an error.

Hmm, must be something else needs to done differently when you tick this.

Well, I have just RESTARTED BPP just now in the back ground, while I do some work.

I have now tried your suggetion:

Darks go in DARK column

Flats & Dark Fats from one session go in the FLATS column

Lights from one session go into the LIGHTS column

The I choose CUSTOM:

Give the the OTHER session's Fs, DFs & Ls a name under the option: FILTER NAME.

So, in the end i have:

Darks in darks column

Flats & Dark flats from one session in the SAME column with the Flats & Dark Flats from the other session, but separated into 2 groups based on the name i gave them.

TICKED THE BOX FOR DARK FLATS.

Lights from one session in the SAME column with the Lights from the other session, but separated into 2 groups based on the name i gave them.

Diagnostics just warned me that there are no Bias files.

Clicked RUN.

I will update you in about 45 minutes to an hour...

fingers crossed...

Fingeres crossed here too.

Strength should be threshold, my bad.

Here's an image I'm currently working on where I used this recipe.

This is an extreme crop, so you can see the individual pixels. Chroma noise reduction was done AFTER colour calibration. As you can see, the colour is much more neutral after noise reduction, but the image looks as noisy as before. This is intensity or lightness noise. There still is a weak greenish large scale structure left after noise reduction. Also note that stars were not affected.

These are the settings I used for this image

I got away with less noise reduction in this image. But since I didn't use all 8 layers, there was still some structure left afterwards.

In MLT, you start by saying:

Extract a luminance layer (CIE L*) from the image, using channel extraction.

There are TWO options:

CIE L* a*b* AND CIE*c*h*?

Which one did you mean by CIE*L?

Just completed...

Failed

error message

Cannot calibrate Lights...

Seems that the first process I did is the only way it worked?

Dark Flats going into BIAS...?

I use cie L from Lab. There's a toolbar button for this in PI.

Holy thread revival.  How did you get on?

You should not have "optimise dark frames" ticked in WBPP with a CMOS sensor - OSC or mono.  Darks should match lights exactly in exposure.  Flat-darks should match exactly flats.  Dark current is not linear in CMOS sensors so you cannot optimise darks.

You debayer after image calibration.

You should cosmetically correct immediatly before image registration.
