- เผยแพร่เมื่อ 2 มี.ค. 2023
- This video explores the latest addition to the popular astrophotography software, Siril. You'll learn about the new noise reduction feature and how it can enhance your astrophotography images. The video provides a step-by-step guide to using the noise reduction function and demonstrates its effectiveness in reducing noise while preserving important details in the image. I'll also share useful tips and best practices for using this new tool and hopefully answer the common questions about its functionality.

I'm diving into SIRIL as my main processing software. Your videos have been more helpful than anything, anywhere. Keep those great tutorials coming!
Thanks so much! I'm glad to hear they've been helpful!
Great video as always! It's nice to see someone promoting Siril. I have to give a demo of Siril next week in our astronomy club. Your video's just made it a lot easier for me to prepare for the presentation. Many thanks and keep up the excellent work!
Thanks! Wow! That's great to hear!
Thanks for all these SIRIL videos and congrats on being listed on their website for info.
You're welcome and thank you!
Hi, big thank you. your videos make Siril much clearer for me.
Glad to hear it! Thanks!
I am really enjoying working with SIRIL. Excellent software!
It really is, and it'll only get better!
Props to ya for being added to Siril's page as a resource to learn the software.
Thank you!
Thank you for such insightful and detailed videos on Siril
You're welcome and thank you for the comment!
Big Thank I did not know about this feature
You're welcome!
this'll hopefully help me a bit cus most of my images are just noise for some reason. i use iso 1000 and i take roughly 45s subs each time and i take 30 of each calibration frame
Hello Rich, very nice content. Trying to process several sessions of m78 with the aid of Sirilic with standard settings except drizzle and background extraction, would be great an indeep video about all the advanced settings values that will help a lot to have good images (especially gradients and noise removal). Have a nice day!
Thanks! Yep that's my plan to go through and provide content on most of the settings. I have an in-depth video on background extraction, if you haven't seen it.
Hello, sincere congratulations for your videos, you are really getting some news from Siril ... super.
It's a bit difficult to follow you because my English is really bad, but this doesn't affect your videos. Keep it up.
My question.
What I didn't understand is whether only one type of noise reduction should be applied (salt and pepper or Ascombe or dual domain or sos) or advice to apply them all, but one at a time.
Ciao ciao.
Thank you! The salt and peeper should only be applied if you did not apply Cosmetic Correction from the Image Processing menu. The Ascombe, Dual Domain, and SOS are secondary noise reductions that are applied after the initial NL-Bayes noise reduction. You would probably get bad results if you ran all of them, but it doesn't hurt to try. You can always undo your actions.
Love the videos! I'm using Beta2 and wondering if you could organize your videos in categories of Pre-Stretch/After Stretch. I'm going through doing the denoise, etc. and it's helpful to know which steps are best at those points. Thanks!
Thanks! Unfortunately I can't do that. Things would get cluttered I think with existing play lists. You could always lookup the commands in Siril's documentation. They've done an excellent job with that.
The best tutorials ive ever seen... You're explaining everything clearly and professionally.. great job..thanks a lot ..I got a question about processing.. Cygnus loop..as I saw you got similar picture on this video..
Any idea why after stacking and processing Is it normal..i got to many stars on my image?..and it's hard later to get all nebula details later.. even using starnet...
Hey thanks so much. If I'm understanding correctly then what I do after Starnet is process the starless image to my liking. Then I use the star recomposition tool to stretch the stars back in. Doing it that way you have control over the stars without affecting the object.
@@DeepSpaceAstrothanks for replying.. yes I understand I can play I do the stars in recomposition as I like..
The think is I dont have that much details on nebulas.. and IAM just thinking iif it not enough data..or bad processing..
I've got like 5 hours lights.. with askar fra400 5.6 on canon 6d..
So.. comparing the similar results on astrobin it should be enough to brings out more nebulositie..
Maybe it's becouse of calibration frames.. I have darks and biases..no flats
I notice once a noise algorithm finishes the image looks brighter. I guess at this stage you adjust this during histogram stretching later on.
You can, yes. Siril's noise reduction works best with mono images, per Siril. I usually use PS or Topaz DeNoise for OSC images.
Really enjoying your videos on Siril. Question on Noise reduction, when do you apply it? Do you apply it after stretching or should you apply it after star removal? My images are all undersampled.
Thanks! It's recommended to always run it before stretching. I usually run it after removing the stars which is also done before stretching. It's up to you whether or not you remove the stars first, but I feel I get better results that way.
@@DeepSpaceAstro awesome. Thanks for replying. Will try this method after removing the stars.
Have you tried to compare it to the median filter that was there before? It could be used as a way to reduce the noise too
I have not, but the median filter is still there.
How does this compare to NoiseXTerminator in terms of effectiveness? Which should I be using?
Sorry. I don't have any experience with NoiseX
Is this software applicable to reduce speckle noise
The stacking function with increase your signal to noise ratio, and you can use noise reduction to help with any noise left.
I used my Iphone and binoculars to take a picture and used AI software and NOW IT LOOKS EXACTLY LIKE HUBBLE !! I don't know why people use telescope anymore..NO NEED! 😮
I'm selling all my gear now!
This may be the most complicated thing I've ever tried to do in my life. I'm at a loss on what the hell all these buttons and sliders do how on earth did you figure all this out is there somewhere that a noobie can go and start from step one.
I have a start to finish video for Siril, besides that the documentation is well written.
