I’m currently experiencing some issues with Siril on my new PC, which has been quite frustrating. In the past, I primarily used star processing to focus on the object itself, and I had no problems with Siril. However, I now need to figure out how to process astrophotography images without using Starnet, as Siril isn’t generating star masks or starless images anymore. I could really use some help or suggestions from anyone out there. It’s challenging to follow tutorials for processing, especially when working with galaxies or similar objects. If you have any ideas on how to effectively use Siril without Starnet, please share!
Can We Process Astrophotography Images Better Without Starnet?

Have you entered the correct program path for Starnet in preferences? Siril doesn't do star removal natively, it simply points to the Starnet application to do the removal and file creation. Also, you can always run Starnet stand alone if you need to.

I don't really understand what you're talking about. Siril uses starnet++ to create starless and starmask images. It works on almost all versions of Siril

It is set up in the preferences at the Starnet executable slot. Or that's all I can recall. IDK what the other 2 are meant for unless those are important too.

Just looking forward to some help if there is a way to process any Astrophotography image without the starnet. Cause we know that helps us a lot. But, what if we can't use it cause it didn't create the starless and star mask fit files? That is what I want to know.
Considering how much brighter the stars are than the objects that are usually photographed, there are two options:
1. The stars will be greatly overexposed, the space object will be fine.
2. The stars will be fine, the space object will be without much detail or not visible at all.

Hi, You can use the Siril generalized hyperbolic stretch function or the asinh stretch function to process with stars. However best is to remove stars at some point in your workflow to prevent star bloat. If starnet integrated with Siril not working for whatever reason, you can run starnet++ separately. Just make sure that you have a little bit of stretch otherwise starnet will not work properly.
In Photoshop you can minimize the stars without any plugins. See here https://youtu.be/pX4GpEXjoX0?si=oVVqX4kKAGavNoJ-

Up until Starnet++ and starxterminator the process was to do star reduction in Photoshop or pixinsight. There are plenty of videos on YouTube that can explain it better than a forum allows.

What I am trying to get across is that Starnet is NOT built into Siril, it's an outside application. If you were to download a fresh install of Siril Starnet wouldn't be available until you have tell Siril where the executable is located on your computer.
On the question about processing without using Starnet, well of course you can. I do that all the time. It may seem like it but it's not a requirement to remove the stars from an image. There can be good reasons to do so but you certainly don't have to. For most of the history of astrophotography there was no way to easily remove the stars and process everything separately, certainly not before the advent of using digital cameras.

That is not exactly the case. It depends a lot on how long your subs are, how much full well you have and how hard you stretch. With a little care it's certainly possible have both the majority of stars unclipped and the object of interest well rendered in an image. Remember that starX was first released in 2021.

When I tried to run Starnet, it applied some kind of stretch, but it did not create the starless and star mask files.
It can be related to that it wasn't functioning properly, or it can be a working directory issue?

True. But it takes so much more time and you'll lose dynamic range anyway.
*starnet was released earlier =)
Yes, 2019, still, fairly recent in the history of astrophotography.
You guys remove stars???
Sometimes we borrow them but we always put them back ;-0

you can process images without starnet. Clusters and Galaxies can be processed without star removal. Nebulas are the things that often seem to benefit most from using starnet, as the nebulas are often dim and the stars are bright, so independent processing does makes sense.
there is an RC astro program called Star Shrink that works well for images that have stars in them that need taming down a bit. about $60.
Affinity photos has some great Macros from James Ritson which also have star removal and reduction presets. Affinity is good.
