我的望远镜加上行星相机低倍率都只能拍局部

最近在研究ATWT，使用它抽取提升或删除图像的频率。我有时会用它强化细节和强力降噪。大家还知道有什么作用吗？但是MMT和MLT我基本没有用过，我不知道这3者有什么异同和优缺点。

The purple coloration is not the star's own color, it can be caused by chromatic aberration or an artificial byproduct of the stretching process.Interestingly, the "Unpurple-filter" in Siril does not always handle the problem satisfactorily, or not effectively enough. Sometimes, it can adversely affect the color of the image.- The solution comes from the fact that the inverse color of the purple hue is green, so the intense purple hue appears green on the negative of the images.In SIRIL, use the following simple steps in the menu:-> Image processing - Negative transformation-> Image processing - Remove green(!) noise...then use the "Negative Transformation" again to get the image back to normal color.Much easier to do than to describe. It's all in a few clicks. Have fun!

加装IR685拍出的照片该如何用另外一张普通照片合成彩色照片？各位大佬，能给一下教程吗？另外，还有什么办法可以提高拍月球时的画质？

I've been exploring different ways to process images from my Seestar S30 Pro, and I'm curious to know what the community is using. My goal is simple: Get the best possible image quality. Keep the workflow fast and beginner-friendly. Take advantage of AI-powered tools without spending hours learning complex software. I've looked at options like AstroEdit, GraXpert, Cosmic Clarity, Siril, PixInsight, and others, but I'd love to hear from people with real-world experience. What does your workflow look like? Which software or apps do you use? Do you process on a PC, Mac, or mobile device? Has AI genuinely improved your results? If you could recommend just one tool for Seestar users, what would it be and why? I'm hoping this discussion can help newcomers—and maybe even experienced users—discover the simplest way to achieve great results. Clear skies! 🌌🔭

@Harold Soto ，Thank you for helping me answer my questions again 我想表达的意思如图所示，seestar拍出来的东西，没有暗场，它自带暗场。智能降噪后导出的图片也不是raw，所以我认为对于后期来说会有比较大的影响，如果导出原文件（fit），那么原文件本身就有很多热噪点，但seestar又没有暗场可以降噪，这就始终困扰着我，我很疑惑在天文社区里面的其他星友，你们的作品是如何拍出彩色，哈勃色的呢？ 这个色彩该怎么从原始的米黄色转换为这种彩色？我又该用哪款后期软件？是pixinsight？还是siril？又该如何操作？例如原fit文件会有热噪点，该怎么在没有暗场的情况下去除？还是说seestar可以导出暗场？米黄色的星系们，又该怎样后期成像本帖子所参考展示的M51一样的彩色？ 综合下来，我有几个问题总结： ①Seestar可以导出暗场吗？②Seestar最终堆栈成图导出的原文件是fit格式，自带热噪点，想要在电脑后期该如何应对这些热噪点？是需要用到“保存单帧”这个功能吗？③Seestar拍出来的星系绝大部分是黄色的，该怎么通过后期转为彩色，大概分几个步骤，又会用到哪些后期工具？是siril？还是pixinsight？

Hi everyone,​I am getting an error message while trying to run the SpectroPhotometric Color Calibration (SPCC) tool in Siril. The process halts and displays the message: "Catalogue error: no stars identified".​I have already downloaded the required astrometric and photometric star catalogues to my local computer. Specifically, I have downloaded all the data tracks visible from my location here in Italy (omitting only the Magellanic Clouds).​This is the first time I have encountered this issue since I started using Siril, and it has previously always worked without a hitch on my other images.​Could anyone help me understand what might be causing this error and how I can go about fixing it?​Thanks in advance for your help!

May I ask if Starnet ++ can generate two files when performing star point removal like starless starnet++在进行星点移出时能像starless一样生成两副文件吗 What I mean is to generate a pure star point file and a pure nebula file我的意思是生成一副纯星点文件与一副纯星云文件

我是个天文新手，请各位大佬们给我推荐一个天文后期软件，谢谢

This is what I came with any feedback and improvements? Bortle 7 232 mins S50. My goal was to get the colours out of the stars and to see as many stars as possible

With seestar s50 most of the time a object like caldwell 15 will be just a blob of light, is there a way to get detail of it should i have a very long exposure? Or just a proper workflow on siril?

I am trying to begin using the Siril stacking app but apparently I need to have all of these different kinds of images. Obviously, lights are the most simple so I don't need any guidance for that. I've watched videos on every type, but the vast majority were not relating to smart telescopes. I would really appreciate some help to becoming a better astrophotographer!

People dosent know the difference between AI post processing (typical blurrX noiseX and so on) and chat gpt (or whichever LLM). There are still plenty of AI generated images being posted. Puting an image in any generative AI and say please donoise this image is not post processing! If you want to learn processing, there is awesome free tools and ressources out there. If not, please do not lie about it and be lucid that images after being "processed" by generative AI are not yours anymore. Even if you spend 10h integrating a target, you could have fed the AI a piece of wood and ended up with a picture of a DSO...

In my Seestar album can I find out how my image was taken eg Alt v EQ, exposure time etc

Just to be clear, i have an iPhone 17 and an iPhone 12 mini.
