Seestar s50 and processing in Siril.I would like some advice on what i am missing.
Hello fellow Seestar users!I am enjoying my s50 for about a month now,ive taken some nice pictures,but my experience trying to process the data with Siril has been not very successful.Ive watched tutorials by Deep space astro ,i use the script for Seestar preprocessing make the 4 folders put my light inside,but alot of the images end up super noisy even after the procesing .The guy says that the loss of data during Stretching should be around 0.1percent , when i select the auto strech algorithm its always showing more than 1.5 or even 2 .And the image always looks better just processed in the app itself.I dont know what i am doing worng please advise.

Is pixinsight really worth it?
Should I get pixinsight or keep using free processing software and spend that money on an advanced filter(s)?

LRGB Combination合成如何最大限度发挥图像信噪比？
大家好，我有一个一直以来困扰我的疑问。如何最大限度发挥图像信噪比进行LRGB合成？Pixinsight官方频道建议将WBPP叠加得到的四张Master进行ImageIntegration并选用SNR作为权重算法，关闭排异算法。叠加得到SynL后在非线性阶段与RGB图混合。但是经过一些实验，又有一种说法是将RGB混入L会连累L，因为RGB的Master信噪比远低于L的Master，所以应该直接将纯粹的L在非线性阶段与RGB混合。到底怎样做才是正确的，谢谢大家!

S50 Stacking not working for nebula?
I captured 300 pictures 10sec each of NGC6888 planetary nebula. The nebula is deeply red. With the Deep Sky Stacking feature, it returned green stars to me and no nebula anymore. Tried it again some times, even with only 10 pictures, but it is still not working. And there were some other stacking problems. The auto-enhance while stargazing produced a beautiful picture, but I wanted to stack again to get rid of the satellites passing by that were on 15 photos. Everything right out of my S50. Uninstalled the app, latest firmware was already installed. Unedited with 310 photos in the stack: Unedited with 40 photos in the stack: Last 2 pictures from that stack:

A PixInsight workflow that will give me sharpness without graininess?
Looking for suggestions for a Seestar PI workflow that will sharpen images without making them look grainy. Any suggestions?

Green stars？
Why are there green stars in this astronomical work?Is it an equipment problem or an environmental problem?

Why is one of my pictures under review what does that means? ?
I took a picture of M 52 for the messier challenge and it said is under review. After mosquitoes bite, Rain and lack of sleep to wait for cassiopeia to rise in the horizon enough to take the short exposure of m 52.

Very first try on Pixinsight, thoughts? Not perfect by any means but I think it's a lot better than the equivalent processed in Siril, Graxpert and Gimp. So much to learn, spent hours on it but loved every minute. The 1st image is the Pixinsight one.?

Pixinsight - is it worth it ? How is the learning curve ?
Pixinsight - is it worth it? It's 300 EUR + if you want the best astro plugings for it it will be also aprox. 150 more. I want to start to process the photos with some good software. Siril was in my mind + GraXpert and maybe Cosmic Clarity. What do you think? And also how is the learning curve Pixinsight vs. Siril ?

Processing the stars in my picture?
For a long time I wanted to Delete the stars in my pictures while keeping in the brightness. For example, one of my galaxy or maybe nebula pictures. And I can't figure out how to do it. Can I get some help?

How do you process your images?
Has anyone tips how to process the images on a computer? I use Siril, have a script optimized for Seestar, but the result of the Seestar AI is still better than my editing results. Any tips on how to learn post processing appreciated.
