I am processing the OSC Calibrated images of M45 from the Premium Set from iTelescope. As this is my first attempt at OSC image data, I was wanting to conform that the following is the correct way of loading the initial images:

- Prior to loading the images into APP, use the 0) RAW/FITS Tab to set the pattern (example: RGGB) to match the camera specifications as indicated in the FITS Header, set the algorithm to Adaptive Airy Disk, and check the box for force Bayer CFA.

- Use the 1) Load Tab to load the files into APP. 

As a side note, I attempted to load one image using the above process and the image when checked in APP has a green background tint.

Thanks in advance for advice and guidance

Pleiades M45 APOD RGB

This should not be required, leaving it at the standard settings should process an OSC image that has the correct header information, just fine. Also no need to force Bayer CFA usually.

Well, i have the same issue with images from iTelescope as well as my QHY268c.

When using default settings all images are green, when choosing force Bayer CFA and RGGB Pattern all images and the result is gryscale only.

And it is not a Fits Header issue, all thes images can be processed fine in DeppSkyStacker and PI.
