I think when you receive the BLOB (the image) from INDI, one of the fields is "format". So you may have to wait until you actually receive an image before deciding what type it is.

Also, one of the standard INDI properties is CCD_CFA, which has information needed for debayering (if appropriate).

Keep in mind I don't write many INDI clients. I work mostly on the driver side of things. So I might be wrong.

Hi Kevin and thanks for your response.

I've just had a look at IBLOB::format but this just contains ".fits" and not the pixel format information such as "RAW-8, RAW16 etc".

Any other ideas?

Amanda.

I guess you'll just have to look in the FITS header then, which presumably you're doing anyway in order to decode the image.

Thanks Kevin. I appreciate your help.

That's CCD_CAPTURE_FORMAT property
