Image Processing Challenges / Re: Non Linear PostProcessing
« Last post by dld on 2019 August 20 14:16:28 »
I agree with Gerald, GRBG seems to be the correct pattern. And yes the image is sharp, the camera seems fine, and I am jealous :laugh:. These discrepancies are due to how the various acquisition programs decide to arrange the pixel values into an array of numbers and then into a (FITS) file. 

PS: Take a good read at Rob's post at Cloudy Nights. I think Bernd has some nice posts somewhere in our forum explaining what's going on, but I can't find them at the moment.

Let me add that the change in the Bayermatrix postion happens in my opinion
in your capturing software,  which rotetes the image by 90 degress and therefore changes in the image the bayer mnatrix from
G .. G to
. GG .

Gerald
P.S.: Just Checked the FITS Header of your image which clearly says:
Mirror in Y                   TRUE
QTURN 90 Degrees     TRUE

Setting both values from T like true to F like False should give you the bayermatrix
as mentioned by ZWO  !!!!

So dont rotate and mirror in the capturing software and everything will be fine and easy

@mhambuch,
Your image has excellent colors and is incredible sharp!
Find the link to your image annotated in full size.
http://www.werbeagentur.org/oldwexi/GRBG_clone1_Annotated1.jpg

The Bayer Matrix of your captured image resulted in GRBG  !!!
Using GRBG gives correct Star Colors.

To find out the correct bayer matrix of your image its very simple.
you have 4 possibilities. Those two with RGGB, BGGR  give checkers when you zoom in heavy.
So G cannot be inside the 4 letters. Whats left is either GRBG or GBRG. Doing an STF to these two immediately shows
the red nebula of NGC7000 by using GRBG.

By the way, if this is really a single exposure its a very excellent image!!!#

That’s what I had to do in the end.  All working now.   Can’t think what might have caused it... windows updates are off, so as far as I can tell nothing has changed since the last time I used it a couple of days ago.

But, back and working, so alls not lost!

General / Re: Can I use pixinsight with the NEF RAW files of a Nikon Z 6

I now have a Nikon Z6.

A quick test shows that PixInsight already supports the following raw file formats:
•14 bit Lossless compressed
•14 bit Compressed
•12 bit Lossless compressed
•12 bit Compressed

Uncompressed is not supported but I can't think of a good reason to use uncompressed anyway.

Hello dld,

I have added one of my raw pic under the following link.

According to ZWO, the ASI183MC has a RGGB pattern.

Thanks for your help
