Problem with running the script ("OSC_Preprocessing")

TillN · January 27, 2024, 12:35am

Hello,

I’m very new into astrophotography and wanted to stack my first photo.

So I started with putting the lights, darks, biases and flats in right directories (as it is described in the Tutorial).

If I run the script “OSC_Preprocessing”, it doesnt complete it.
In the sequence “Running command: stack” it interrupts.

I would be very thankful if someone could help me, I’m completely thrown up.

Here is the Console of “Running command: stack”:

I can’t help with the OSC script but I recommend that you get the Sirilic script from the Siril website . It is very easy to use and automates the whole stacking process. It works well on default settings. I have used it for color, dual and, and narrowband.

lock042 · January 27, 2024, 6:27am

Here it fails to compute statistics, from calibrated flats. You should open one of them to check it out.

TillN · January 27, 2024, 9:55am

Hey, thank you for the answere.

Isnt the “OSC_Preprocessing” the build in script I should use (DLSR Photos)?
Here one the Siril website this script is the first one mentioned.

TillN · January 27, 2024, 10:08am

Hey, thank you. That seems to be the problem, but how do I find out what exactly is wrong about the Flats?

I tried it again today and the console prompts:

If I get it correctly, something with the image dimensions is wrong?
But they are all 6264 x 4180 (RAWs and FITs)…

Only the size is different:
The size of the Darks is about 28-28,5MB, of the Lights about 35,5MB and the Flats 18,4MB. Does this mean anything?

I tried running the " OSC_Preprocessing_WithoutDark" and it worked. So the Problem needs to be on the Flats, I just dont know what it is.

I read:

Reading FITS: file bias_stacked, 3 layer(s), 6240x4160 pixels, 16 bits
It should not be in 3 channels. You have a mix of images. Please read this page: Calibration — Siril 1.2.0 documentation

TillN · January 27, 2024, 11:48am

Thank you,
It seems like that was my problem.

I had so many errors yesterday that I tried using JPGs.
As I tried it again today, I forgot to replace the Bias photos with the RAWs as I did with the others…

It now worked and the console in the “# Calibrate Flat Frames” section had no errors:

I’m not really happy with the result but I guess that’s my fault (when I took photos yesterday there was a full moon).

Thank you guys for the Help!

I am very new also, so I can’t help much with the output of the log files. Lock042 sounds like he will be better at interpreting those. My naive reading is that the logs are showing different problems at different points, The MAD is Null error would indicate problems computing statistics for a variety of reasons, one of which is a difference in the files size, resolution, or bit depth. The later error about different dimensions could be pointing to the same issue. But your dimensions seem the same and (to my knowledge) differing file size in MB should not be an issue. The last error youLock42 discussed with you might be the answer. The bias file has three layers vs 1 for all others. Try running without bias files and see what happens. As to which is the right script, either can be used. I prefer Sirilic because it can be used for all types of files. I do a lot of remote imaging, so I am back and forth between mono and broadband images and the more versatile Sirilic script works with them all. Just another thought, if you can’t sort out your file problems. One time I just could not get Siril preprocessing to work so I tried Deep Sky Stacker and it worked fine. I then went back to Siril for further processing. DSS is free and easy to use, although I think it too would choke on the bias frame difference from the others. I have been using PixInsight recently and ran into a set of files that I could not get to stack for the life of me, so I tossed them into Sirilic and Siril handled them without a problem.
