Great tutorial. Thanks. Comment: For integration >30 min, a Seestar produces a lighter diagonal band with dark corners due to field rotation artifacts. To hide these, I use the Siril Background Extraction tool --- more than once before stretching. I often use it once w/o dither and then 2-5 times with dither. It really helps.

One thing I noticed is that if you aren't careful the background extraction will remove large areas of diffuse nebulosity. You might not even know they were there because they were hidden by sky glow or light pollution.

I tried Siril a little while back and didn't get on with it. Since hearing that they incorporated Starnet I thought I'd give it another shot. If it wasn't for your videos I may have given up on it again but you got me through. I've way more to learn but now I know where to find the help and I'm enjoying it. Many thanks!

Have to agree. The guy’s somewhat of a public service as quite a few are. It’s a nightmare trying to find your way around these software packages with their help. Imagine what it would be like without.

I am still not sure if you are selecting bad background you want Siril to correct or good background you want Siril to apply to the whole image?

The samples are telling BGE where the background is, good or bad.

I’ve just tried out using it manually since, everytime I generate otherwise, when i come to right click to remove points I don’t want, Siril crashes and it’s ‘start over again from scratch’. So, doing it manually, I then just sprinkle points around the perimeter of the image and it appears to do a decent job with just 30 or 40 points.

What if you would've done all this in RGB instead of green channel only? The result would be the same?
@DeepSpaceAstro
Жыл бұрын
So first of all, this video was shot using v1.0.6 which did not allow you to work on the RGB channel. The new version 1.2.0 currently in beta however does. To answer your question, yes the result would be the same.

Hiya Rich . I like placing the BE points manually for the exact reasons you mentioned but I do have a question . Some DSO images will eventually reveal faint dust clouds and bands after processing . Will incorrect BE point placement cause this Data to be removed in this step ? I’m worried I’ve been sabotaging my images .
@DeepSpaceAstro

I've actually experimented with what you're asking before. First, it would never completely remove the data. BGE simply creates a synthetic background based on the sample points. A few on the dust, etc. shouldn't cause any noticeable issues. Lots of samples on the DSO or surrounding dust and you will lose data in the sense that it'll wash out/blend with the background. You'll still see those areas but not as they should be. Best advice is to play with it. Place samples where they shouldn't be a have BGE compute the background, then compare that to proper sample placement. Hope that helps.
