Colour in narrow band.

[xelasnave]

I have a few images of M8 about 15 @ 30 seconds for each of the 7 filters.
I stacked each set in Deep Sky Stacker and they are each black and white.
Is the colour added to each channel before combining or have I just selected the wrong options in DSS?
I know the next step is to get pixinsite but at the moment I have been more interested in getting all the gear working and my attempts at processing with this small batch is just to get a feel for the process.
The images were fits files and I guess I must ask also if fits are what I should be capturing.

Have you registered each of your DSS filter output files against each other? If your using Photoshop it is much simpler (and quicker) to align all these files before taking them into Photoshop. I can't speak about how PI does it or what it needs as input, you will need to consult the Cult for that info.

The DSS layering alignment is pretty simple:

Open DSS, and pick up each of your stacked and registered filter output files. Tick the option to "Register Already Registered Files", this will ensure these output files are registered against each other. Also tick the "create a REQ file", this will then create an aligned (registered) file for each channel (which gives you a working output file for Photoshop) It runs quickly.

Then in Photoshop, open the REQ files for each filter channel, and convert the mono file to RGB, you can the go ahead with your stretching etc. I usually work to equalise the histogram for each filter. Once your happy with the individual filter files, start your colour layering.

Hi Glen. Where may I find this button?

Hi Glen
I hope you are well and thank you for such a comprehensive reply.
My proceedure was to register each group of captures one group at a time and then stack them.

Sorry, I will explain.

When you pick up your registered filter output files, and open them as lights (picture) files, check them in DSS. Click Register checked pictures...

The Register Settings box will open. Tick the "Register Already Registered pictures" on that page. You want to select the 100%, but you don't need to stack them as you can't really use the stacked blended file. Push "Stacking Parameters" button, select the "Intermediate Files" tab, when that opens you will see (second line down) a box to tick for "Create a registered/calibrated file for each light frame", tick that box to great your reg files.
Select the TIFF file format just below that.

That should take care of it.
