I had a go with Siril as it can apparently handle the raw files that Fujifilm cameras create. I'm not keen on the tonnes of .fit files it creates at each stage, but they can be deleted manually.

 

I followed the tutorials on the website after trying to muddle my way through and I've got to something I'd like to export to process further.

 

But I can't seem to do so. Saving the RGB image to a tif results in some unusable kaleidoscopic mess. Saving to jpg results in a nearly-all white image.

 

So how does one actually export a usable or indeed viewable image from Siril?

I use Siril in Linux for most of my preprocessing and find it to excellent. Right click on the RGB image and save as TIFF works for me every time. Not sure why the file should be corrupted.

 

However, it's not really necessary to export from the RGB. I find StarTools handles the stacked fit file. Other astro processing programs should too.

I installed the nightly build (Ubuntu's repositories are still at 0.9.9) and reran everything... same results upon Save As (white jpg, kaleidoscope tif).

Please. Share the FITS picture you cannot save.

Those files are 90 MB...

 

I tried something else last night. I opened all the .RAFs in Darktable and exported them from there in TIF. I then imported those TIFs into Siril and went through the processing. This time I was able to successfully export a usable image.

 

So there is something about the conversion from RAF to FITS that doesn't go quite right. It looks fine from within Siril, but it just won't export RAF-converted properly.

There's plenty solution to share files that big.

Also I tried top open a RAF file and saving it as TIFF. No problem.

I need your image.

I've determined that there is no point in me sharing my FIT file because it won't show the issue. Why? Because the act of explicitly opening a FIT file eliminates the issue.

 

I just tried yet again and can replicate the issue but can also solve the issue:

 

1. Load RAF files in the File Conversion tab

2. Go through the operations in Pre-processing, Registration & Stacking tabs. This ultimately puts out an RGB window.

3. Right-click in the RGB window and save as a JPG, and again as a TIFF

4. Open that JPG. It should be white or nearly all white. The TIFF will be kaleidoscopic.

5. Now go to File and Open the very same FIT file generated in step 2. Closing Siril isn't even necessary - just open the FIT that you're apparently working on.

6. Go to its RGB window and save as JPG and TIFF

7. This time, the JPG and TIFF are fine.

 

Whereas with TIF files as the starting point, I can do this:

 

1. Open Darktable, load RAF files then export as TIF

2. Load TIF files in the File Conversion tab

3. Go through the operations in Pre-processing, Registration & Stacking tabs. This ultimately puts out an RGB window.

4. Right-click in the RGB window and save as a JPG, and again as a TIFF

5. The JPG and TIFF are fine

I probably found the bug and fixed it in the next version.

Still working in 0.9.11-alpha5 - using your ppa I think? Save as 16bit tiff.
