Hello,

To work with APP I need to convert DSLR RAWs to FITS, I did this with PixInsight´s batch format conversion.

The raws are 16 bit OSC.

In PixInsight´s format conversion  I set input hints to "raw cfa"
..... - output format hints: empty

In APP I set 0) RAW/FITS: force bayer CFA

With APP I calibrated LIGHTS, BIAS, FLATS..., analysed stars

APP shows "no cfa" in the image list.

When trying to analyse stars APP reports : "lights have only 1 channel", "Master BIAs / FLATS have 3 channels"

These are the informations concerning format hints in PI:

raw (r ) Load a raw Bayer RGB image without interpolation,

                              no white balancing, no black point correction,
                              with unused frame areas cropped, no frame
                              rotation, no highlights clipping, and no noise
                              reduction.
-------------------------------------------------------------------------------
cfa                     (r )  Load a monochrome raw CFA frame.
-------------------------------------------------------------------------------
no-cfa                  (r )  Do not load a monochrome raw CFA frame.
-------------------------------------------------------------------------------
bayer-drizzle           (r )  Load a raw Bayer RGB image without interpolation.
-------------------------------------------------------------------------------
no-bayer-drizzle        (r )  Do not load a raw Bayer RGB image.

 

Any suggestions (set: no-cfa?....)

Peter

You shouldn't have to convert raw's from a DSLR if they are supported by APP. Which camera are you using and did you try just loading the raws in?

...they are not supported:  IIQ /PhaseOne files. (this digital back should not be used for astro.... no surprise, but I have a landscape + milky way image (lights, bias, flats) from Tanzania which I want to develop).

Actually I am doing the second try

Nice! Would love to see it! More and more models are being supported, in the upcoming 1.076 a lot will be added. Not sure about yours though.
