Hello.
What a big message. Will try to answer to everything.
First, thanks for your kind message.
Second, as you said, astrophotography is a particularly difficult area where the prerequisites are mandatory.
Siril is not really difficult to use, astrophotography need to be understood first. Try to use Blender with no 3D prerequisites ? If I try it I will feel like a chicken using a knife. And this is normal.
Scripts have been created for that, for helping people to process their image as soon as they have first subs. However, you will never have a better result with scripts as if you do it manually.
DSS can do it all automatically, yes that is true, however as you said, result looks nicer with Siril ? Why ? Because Siril needs some human intervention. I don’t believe in a all automatic software, for every situation.
You can add it in the script if you want. Also Sirilic can write scripts for you with no effort.
This can be done too in the script. But to know the best image a first pass need to be done. Ideally I would apply a “PSF for the sequence”. This is a tool dedicated for that. But it can not be implemented in scripts for many reasons and the main is you need to chose the star you want to analyze.
I’m sorry, I don’t understand. What do you mean by ppl ?
Only preprocessing have been scripted. Because it is reproductible steps. This is just maths.
Sirilic is dedicated to it. It is not difficult to use. In fact, if we used to code something for multisession we would code it like it is in sirilic. So we don’t want to reinvent the wheel.
Have you ever tried PixInsight? This software is a way more complicated to use than Siril. But it is better too. DSS is easy to use yes, but we do prefer quality. I’m not saying that DSS is bad, but again the “all automatic” has its down side.
Over the past few months we’ve been writing a lot of new tutorials, with lots of screenshots. I believe Siril is now more affordable than before. You can find the whole documentation of sirilic too.
Cheers,
