Hello, I’m new to Siril and watched some really good videos on using Siril to stack images. The process itself is great and I’m able to do it.
However, over the past several nights, I’ve been taking photos of M101. I have the appropriate biases, darks, and flats. No issues there, Siril processed those just fine and gave me the masters for them. The issue I am running in to is that of the 83 lights I have, Siril only was able to stack 2 of them, which seems very very odd.
I then tried it with DSS, and all went well using pretty much all default… just telling it where the biases, darks, flats, and lights are, registering all images, then stacking.
I attached the images I’m trying to stack in Siril. The orientation of the images didn’t matter in DSS, it figured it out and auto rotated appropriately to align the stars. I assume Siril does the same, but to only want to stack 2 images?
I’m not sure where to go from here. Are there some settings that need adjusted? Something in a log somewhere that would give a clue?
The number of detected stars is indeed low.
There are some track to follow to get it works. You can try to update star detection : Dynamic PSF — Siril 1.3.0 documentation
Hmm, how many stars does it need to detect? I can clearly see at least 50 really good quality starts around the center of the image (more further out) in each photo without doing any stretching or anything else. It looks like there’s always between 50-100 stars being detected in each image, so not sure why that’s an issue, especially that DSS can do it really well.
Thanks for the link. I will give those settings a look through and see if that helps and will report back!
That did it! It worked beautifully, thanks so much!
Reference image? I did not see an option for that anywhere. I just used a few images to see what worked best for the Dynamic PSF tool. I’ll have to find some kind of full Siril course. In DSS I can right-click on an image in the list and set it as reference image, but I did not notice any options in Siril for it (then again I did not look for that specifically as I didn’t know it was an option).
Hello I sometimes have the same problem.
I take a really good light frame and give it a New name. As I understand it, Siril uses the first frame as reference. If you give this “best” frame the lowest number, Siril will use this frame as reference.
Works with me every time
That doesn’t work for me. I’m using a mirrorless camera resulting in a bunch of raw files, and it doesn’t let me load anything into the sequence. It doesn’t find any. I have all the light frames in the “lights” folder as I understand they should be. Basically left with a blank sequencing tab in which I can’t do anything in.
If I change my home directory to the process directory, then it lets me. But I have a feeling then I won’t be able to use the scripts as they are. If I choose a reference frame, then switch back the home directory up a level, will it take?
I opened the script to read it, it seems very simple. But I’m so new to Siril I don’t know where to find those functions in the GUI to process it the same way the script does in order to get better control of the flow.
Is there a good course that uses the latest version of Siril that does a proper tutorial if you know what I mean? More or less a start to finish kind of thing of the most relevant parts (but not so in depth it takes hours and hours to get through the video)
The documentation is great for referencing and deep diving, but a video of step-by-step has a ton of value as a starting point.
