FITS viewer shows green image?

Hi!

After a few months away from astro stuff (moving to a new house), I now have unpacked and have enverything up and running again. And I ran into something that for me is new: on and off, the captured images shows all green in the FITS viewer, impossible to see anything. Setup: Canon 1000D on the scope, R-Pi at the scope running Indiserver, connected through an ethernet cable to the house where I run Ekos on a laptop.

THere seems not to be anything wrong with the subs as such - they open nicely in Pixinsight and looks good. So why green in FITS viewer? I do use a CLS clip on filter on the camera that supress the red, but since the subs are not debayered, they should be b/w, right?

And: on and off it looks as I expect, black & white images, very clear.

Any idea about what is happening here? What logs would be useful?

Try to change Debayer setting in File --> Debayer

The GPhoto driver assumes bayer pattern is RGGB, if it is different, then change it in the driver.

HI!

Doesn't help much. Changing pattern changes the dominating hue of the image, but still not usable. But: on and off the images are actually shown in a useful format, that I have always taken as not debayered - black & white. Is there a way to turn debayering off?

Here is a sample fits file if you want to have a look:

Hello, I downloaded your sample shot. Opened it in Nebulosity4, FitsLiberator, FITSPreview and KStars (openFits). All looked good.
What are your settings for FITS files under "configuration>FITS"?
For my Canon 60D, I have gotten good results with turning off "Auto_Debayer" and "3D Cube".

Hi!

Thanks, there it was! I belive it did not auto-debayer previously (some months ago) - is that right? Anyway, turning auto-debayer off makes it very useable again.

Thanks.
