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。

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!

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.

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 #

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

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

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. 👍😁

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)

Hi all! Are there any good tips on bringing out crisp, sharper images? I feel like mine are just kinda flat. A few, for examples.

我最近很想学天文后期，但是我这边一直阴天，有人可以给我分享一些FITS素材吗感谢🥹
