Re: HOWTO Debayer Captured Images

Hi Kirk,

a separate program to decompress TIFF files is just too much work all the way down the line (writing it, maintaining it, documenting it, etc). An option is nice and simple and 10 minutes effort and it even has a little warning explaining that compressed TIFF files may not open in some software. Job done and back to thinking about what SharpCap 3.3 will do :)

I expect that compressed TIFF files actually use more resources in SharpCap (you have to have an uncompressed image and the compressed data, you have to do the compression, etc). Overall, unless you are using one of those full frame 35Mp cameras in RGBx16 bit mode for about 200 megabytes per frame then I think all will be fine. If you *are* using one of those cameras then please send it to me for testing :)

cheers,

Robin

PIPP leaving a line on photo

Post by aajune »

I processed a FITS file using PIPP (all my photos give this result), and there is a line just past the 1400 point from the top of the picture to the bottom. Am I doing something wrong?

Hi,

I think you will need to post a screenshot so that we can see what the problem is in a bit more detail.

Cheers, Robin

Access to a single unprocessed FITS file and the process steps followed in PIPP would help with this.

I had to create an account just to say thanks for working this out
I had exactly the same problem with the same camera and was tearing my hair out trying to sort it until a google search brought me your post.
Well thought out sir! :D

Thanks for the kind words. There will be more of these type of documents coming along as my knowledge advances.

in practice, this doesnt really work!!

PIPP requires a UNCOMPRESSED TIFF and it seems impossible to get such a file, regardless of settings.
So, this turns into a giant hassle, trying to uncompress a tif file, wich is not so easy.

SC 3.2 pr is a very nice app, but yoju need to write TiF and perhaps FITS files properly debeyered before saving to storage.

Try this in File > Sharpcap Settings > General tab

The debayer step for FITS files is usually performed after calibration has been completed. For your consideration, a ZWO ASI2600MC will produce a RAW16 file of size 50Mb. The debayered 32-bit FITS in APP is 300Mb. That would be a lot of disk space needed for a typical capture.
