Nightscape 8300 color images open as gray and not rgb

[doleman]

I'm just starting and new to PI...this is my first post.  I'm feel that I may have a basic question here but I've tried to search the forum and Internet with no luck.  When I open images captured with my Celestron Nightscape 8300 color the images all open as 'gray'.  Is there a simple setting somewhere that I need to change?  When I open RAW DSLR images they open as RGB.  This results in the errors below.

** Warning: The file format reports no CFA pattern for the master dark frame, but it is being forced as per process instance parameters.

** Warning: No correlation between the master dark and target frames (channel 0).

*** Error:
*** Error: Unable to acquire CFA pattern information: Unavailable or invalid image properties.

Any help on this problem would be appreciated.

Thanks,
Jim

they need to be debayered - so do DSLR images, but they are handled by the DSLR_RAW module which can be set to debayer the images as they are being opened.

so the first step is to determine the right bayer matrix ordering (RGGB, RGBG, etc.) for this camera (which should be available online or in the camera documentation) and then open the file to the desktop. at that point you need to open the Debayer process, select the right matrix ordering, and apply the debayer process to the image.

the errors you are reporting are coming from BPP? in fact, when calibrating images they should be treated as CFA images, which are greyscale. i don't use BPP much but there must be a place to specify the bayer pattern for your camera, right? in other words, forcing CFA is correct but i wonder if the right bayer matrix pattern was not set properly in the BPP interface.

Thanks for the information...yep, I had to debayer the files first.   It made all the difference in the world!  I was using BPP and there is still a problem with 'no correlation between the master dark and the target frames' but when I did it manually it worked fine.
