PixInsight DeBayer Question

[Shelster1973]

Am starting to get to grips with PI (cheers again Harry) but am having a few issues with my images.

1st one, which I have resolved was running the Batch PreProcessing script was not recognising any stars....turns out I need to deBayer before registering, which leads me onto my current issue.

When I run the batch deBayer script, the images are completely colour washed out.  The default settings give me a very red image.  Is there something I am doing wrong or is it a case of work through and all will come good when I channel align and DBE it?

Hello,

could you maybe post an example image. In the debayer options what type of matrix have you chosen? If i`m not completely wrong your camera should have an rggb matrix. Also the debayering can already be done in the registration step (just check the box next to CFA and choose the right matrix).

A reddish tint is more or less normal i think, as the debayering algorithm applies the rgb channel scaling for the non modified camera.

best regards

Frosty,

Will stick a picture up later on this evening when I get home and have a chance.

The settings I went for were RGGB.  I did try the option of CFA in the script but seem to recall that it failed on there too.....was a long day yesterday so may be confusing myself there.

Will try and re-run the crip again too and see what happens....

A very Red image is pretty standard when I debayer my DSLR images in PI. The colour calibration tools sort it out nicely.

Here is the final integrated image, with STF applied and grabbed using Snipping Tool.

Batch deBayer settings are set to VNG and RGGB.  Evaluate noise check box is ticked.

Have tried the other bayer/mosaic patterns and they turn out as colour washed as that, just not in red, but green and blue.

Hi

Have you unlinked the channel in the STF !

Will give you a idea if the setting is correct

What do your Batch PreProcessing script settings look like?

Here's mine. CFA images checked and up-bottom fits unchecked is very important.

[Shelster1973]

Think I may have up bottom fits (giggle) still checked. Will check next week as will be away over weekend.

Harry.....not sure on the unlinked thing.....will check that too....

I did a test and it seems up bottom fits doesn't do anything wrong when processing DSLR images so that's not it for you.

I have processed images earlier and had to turn that option off because they weren't debayered correctly. I don't remember if the images were my own RAW files or files from someone else thou.

The best way to figure out this is that you share at least 1 of your raw files on dropbox so someone can figure out the problem for you.

[Shelster1973]

Will throw one on Dropbox later on.

Cheers all for the help

Sorry for late reply, been a very busy week in work.

Hopefully here is a link to a RAW file
