CCD stack help

Been using CCD stack for a trial, and after converting raw to dng, importing and registering/stacking then converting to 16 bit tiff, I am arriving at the following image in photoshop. It shows RBG data but the image looks strangely greyscale......

any ideas at all at to why??

In camera settings, is your camera setup as One Shot Colour or monochrome?

It looks to me like the image has been converted to greyscale, but saved as RGB... Giving it the R G and B channels, all with the exact same data in it.

yep it is set to one shot colour, I have been following the ccdware help guide for this. Images were taken with a Canon 50D so i have to de-bayer them at some point...... is it better to split the files into R,G,B or keep as OSC image?

From what I've heard from other people, the resulting image is near identical from splitting RGB as it is from keeping it OSC.. I wouldn't know personally, I've never bothered splitting them up...

seem to have figured it out.... adobe DNG converter is the first step from .cr2 into dng (ccd stack will not take .cr2) and this is the program ccdware recommends. I have started using nebulosity for conversion from .cr2 into .fit which is doing a much better job.

Thanks alex for your thoughts

Regards,
Grahame,

Glad you got it sorted Grahame, sorry I couldn't be more useful.. I only just got the program myself and I'm still working it out.

We are all in the same boat so to speak when it comes to processing images with new software
