Some questions about starnet++?关于starnet++的一些问题?

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

Tried editing m13 with siril what should I inprove?

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

How to get detail out of a planetairy nebula?

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?

What is the process that I need to go through to get flats, darks, and biases on the SeeStar S30 Pro?

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!

Generative AI is still rampant

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...

深空摄影后期处理流程(适用于2个双窄带滤镜拍摄的2组素材)

(多多保存)siril:星点对齐(右上角转换功能,添加素材,序列名称设置,转换;对齐,去对齐)(分别对两个文件)自动拉伸预览背景提取图像解析、测光法色彩校准(可选)除去绿色噪声(可选)反双曲线变换(可选)改回线性预览星点去除通道拆分像素数学,设置SHO通道 rgb合成除去绿色噪声序列 选择starmask_r_ZH序列叠加星点重混合截去边缘黑框直方图变换 测光法色彩校准保存tiff Topaz DeNoise AI:降噪锐化(severe noise模式,或者手动选择参数21&42) siril: 背景提取(again)以突出星系与星云内容 PS:camera raw滤镜黑色降低,白色拉高,对比度微拉高,高光微拉低,阴影微拉低,清晰度拉高,晕影拉低,去除薄雾拉高,锐化微拉高,减少杂色微拉高导出为jpg

天文摄影中快速在海量照片中剔除掉拖尾照片的几种方法

A. 使用 Siril(免费开源天文软件) Siril 有强大的图像筛选功能。 将所有照片导入 Siril 的序列(Sequence)。运行 stat 命令(统计分析)。查看输出的 FWHM(半高全宽)或 HFD(半高宽)数值。数值小且稳定:星点锐利,对焦准确。数值突然变大或波动剧烈:说明该张照片失焦、有云或抖动。你可以根据 HFD 数值排序,直接剔除数值异常高的照片。B. 使用 PixInsight 的 SubframeSelector 脚本 使用 SubframeSelector 脚本分析所有图像。它会生成一个表格,包含 Eccentricity(偏心率)和 FWHM。Eccentricity(偏心率):0 代表正圆,越接近 1 越椭圆。脱线的星星偏心率会很高(>0.3 或 >0.5)。FWHM:数值越大星点越散。按偏心率排序,一键剔除高偏心率的图。C. 简单的 Python 脚本(进阶) 如果你会一点代码,用 astropy 或 opencv 写个脚本: 提取画面中最亮的 10 个点。计算它们的轮廓(Contour)或椭圆拟合。如果长宽比(Aspect Ratio)> 1.5,或者圆度(Circularity)< 0.5,标记为“脱线”。D. “ blink ”眨眼法(找偶发问题) 操作:在 Photoshop 或 Lightroom 中,全选照片,按 L 键(Lightroom的比较视图)或快速按方向键左右切换。

Is Pixinsight/blurXterminator worth it (as a barely hobby astrophotog)?

update: thanks for all your insights! I gave in and bought Pixinsight and bluXterminator, knowing that its the best software for astrophotography. I already had my testtime with it, so I'm just trying to perfect my workflow for the best possible outcome... old: So I'm editing all my images with Siril (stacking, stretching and star removal), GraXpert(noise reduction, background and deconvolution of objects) and finally photoshop for all the composing and editing. I had tried Pixinsight with bXt and although the gained details where quite astonishing (I guess thats why its used so much in the first place), I think the software is awful in terms of user interface. So, any thoughts on this are welcome!

How should I handle field rotation in multiple DSLR lunar photographs?

I tried using the PIPP > AS!4 > Registax workflow but couldn't find a place to adjust the rotation. I ended up using DSS with a lowered star threshold for stacking, but its ability to correct for atmospheric disturbances seems weak.

🚀 Feedback Wanted: 1-Click Easy Drizzle Script for Siril

Want to increase resolution and sharpen stars on your Seestar or Dwarf images? NASA’s Drizzle algorithm is the answer, but doing it on Siril is not intuitive at all... until now! I made it easy. I’ve written a script that automates the whole process into a single click. I’m looking for feedback from fellow Seestar and Dwarf owners before the public release Request to try it out Thank you! 🙏 #DWARFLAB# #Siril# #Easy Drizzle# #astrophotography # #seestar #

Any suggestion on the best tools/apps to predict ISS transit on Sun and Moon?

Anyone has recommendations and suggestions on the best tools, apps or web services that can be used to accurately predict the ISS transits over Sun and Moon from a given position (latitude and longitude)? And the best techniques for achieving transit images, videos or timelapses with S50? Many thanks to all of you for any help! 👽x

how do i stack raw video with S50?

I've googled how to stack the raw video on the Seestar S50, but when I pull up my video of the moon, I don't see the option to stack. Am I missing something? Video is under 5 minutes

Anyone capturing the Moon passing over the Pleyades?

Does anyone have a chance of making a photo or timelapse of the Moon passing over the Pleyades? My sky does not allow me to... still day light is so strong. Please, post your results if you get something nice and explain your technique. 👍😁

Keeping track of your captures? I built a solo-project app to help! (StarLog)

Hi everyone!I wanted to share something I've been working on. Like many of you, I'm an amateur astronomer and a very happy SeeStar S50 owner. However, as my collection of captures grew, I found it increasingly difficult to keep track of exactly what I had photographed, how much exposure time I had on each object, and what was still missing from my collection.Since I couldn't find a simple way to organize my sessions, I decided to build one myself! I've spent my spare time outside of my regular job developing StarLog.It's a solo project born out of a passion for the hobby. My goal was to make logging your nightly sessions as automated and easy as possible. The app is available on the Google Play Store (so it's fully verified and safe) and is mainly free to use.Key Features for Users:Automatic Import 📥: You can analyze your files directly from your SeeStar or your PC to generate log entries automatically.Detailed List View 📋: Get a clean overview of all your captured objects, including total exposure times and visibility details.Messier "Grand Slam" Tracker 🌠: A dedicated dashboard to see which Messier objects you've already captured and which ones are still on your "to-do" list.Unlimited Custom Lists 📁: Organize your sessions into as many categories or lists as you like.Custom Setups 🔭: While it's perfect for the SeeStars, you can also add other gear if you use other telescopes.I built this to solve my own "file chaos," and I hope it helps some of you too!Since this is a labor of love, I would truly appreciate any feedback, feature requests, or suggestions you might have (and of course a positiv review in the PlayStore). You can find it by searching for "StarLog" on the Google Play Store.As many ask for a iOS-version: Sadly apple wants a yearly fee and the access to a Mac for release and as an amateur and father of two, I sadly cant afford this currently. But it's definetly on the "to-do" list.Wishing you all clear skies and many successful sessions! 🌌(sorry for the gigantic pictures, it seems the forum automatically scales them to full page size)
