does anyone have the same problem as me? everytime i do a denoise on graxpert the picture gets these weird color blobs its really annoying does anyone know how to fix this?

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🥹

I would like to make an attempt to capture sharp Sun details with my S50, e.g. coronal rain, mass ejection, etc. Anyone having success in this mission? Your help is very appreciated!

Hello everyoneFor context, I began processing my images again and have learned PixInsight. My hardest project M 16 was completed in normal framing mode with 3.7k+ files with no problems. I then processed a couple other targets and just decided to tackle a ~15 hour 2x mosaic of the jellyfish nebula region, 12 hours LP (Ha-OIII dualband filter) and 3 hours IRCUT+ star spike mask for stars to emphasize the stars Tejat and Propus. The thing is, 2x mosiac for the seestar is not a 2 panel mosiac. My best description of it is a random density map (the seestar essentially moves around randomly in an enlarged field of view). Some frames are in the middle and some are barely even in this enlarged field of view, some may have like a third of the frame inside the 2x field of view. I call it a density map because the center mathematically should have more integration than a corner. After each session, I had save each frame on and it automatically outputs a master for that session. I definitely cannot use the IRCUT master as is because a plane went through that isn't super prominent but is still there, and it kept a couple pretty bad frames. The lp filter had a couple good masters and bad ones. Note I am confident that drizzle will be effective given my conditions and the ditheringNow for the problems and errors. Essentially, from the entire start of the preprocessing stage to the final part has some sort of an error with an exception to debayer and measurements at some point of my struggles. My usual preprocessing workflow is something like (in WBPP) debayer-> register -> local normalization -> measurements -> subframe selector -> image integration (pixel rejection) -> drizzle integration. Firstly, shoving in my frames in WBPP as they are will output a result cropped down to one frame. This means I have to use a manual reference frame. My first try in attempt 1 (on 3k frames for the lp filter) was debayer -> generate starfield in catalogstarfieldgenerator -> put it as a manual reference frame in WBPP and continue as a tutorial suggested. It failed with the ransac error unable to find and initial linear transformation or something like that. I got maybe 100/3k frames kept. I ran the same thing in staralignment with similar results. I then proceeded with the standalone process star alignment with the same reference frame with the same issue. I checked to make sure the psuedo reference frame had the right dimensions, rotation, size, and matched it to my stacked output from seestar live session. No matter what it seemed to fail and I gave up on it. I then used the stacked output as a reference frame and after multiple iterations it somehow worked. I used generate drizzle data in staralignment and unfortunately I do not remember the settings. I put the registered images from star alignment into WBPP for weighting and local normalization, and local normalization with some weird error but it turned out that I shouldn't have used it any way with a mosiac like mine so it didn't matter. I put it into subframe selector and the variance of certain statistics was extreme, but I figured out the outliers and rejected them after a while. Note at this point I have repeated all the somewhat successful tasks for both lp and IRCUT filters.Next was the part I can't get around: ImageIntegration. I have 16 GB of RAM and it worked perfectly fine for 3.7k files no mosaic with no issues. However, after inputting even the IRCUT data with only 1.2k files I got an insufficient memory error. I spent a long time trying to get around it. First idea was to close every little program and test various numbers working threads. No success. Then I inflated the backup disk RAM (or a "page file"). This is not risky to computer malfunctions and acts like a back up overflow RAM when it runs out. I played it safe and gave myself 16 gigs of back up, but PixInsight had a seizure when it got to backup RAM and the file explorer task ended and PixInsight crashed, leaving me to a grey screen. I have goofed up computers before, so I had a back up restore point before giving myself extra backup RAM and I was easily able to restart file explorer. I tried batches but nothing worked. I had the bright idea of skipping pixel rejection and putting the drizzle files into DrizzleIntegration, but it failed in 2.03 ms with some error that essentially meant either the drizzle files were all corrupted or missing infromation. At that point, I was back to square one. Attempt 2 has been much more of a pain in some ways. I updated WBPP so I can run subframeselector in WBPP and I have been working soley on the IRCUT data to find the best settings. No matter what I do, I can't even register the frames. My IRCUT is some of the best data I have worked with too, so I don't know whats up. I have run at least 20 different settings (haven't counted, but 3 days worth). Main questions: 1. How do I register my frames with this nonsense? 2. How do I get around the RAM issue, preferably without $?

So I got a data set off of Telescope live it comes with Halpha, Lumaniance, Red, Green & Blue files I know how to stack them and I know how to do LRGB & HSO but I've never done LRGB with Halpha and I can't seem to find any videos or anything online if anyone knows how or has a video it would be greatly appreciated thank you.

我把9组图片叠加完成后是先锐化还是先拼接？完成后又该怎么做？需不需要用PS或其它后期软件处理？

Use the HDR feature! This allows you to highlight the picture as clearly as possible!

Now I finally found a reliable way to master HDR photos: 1. Edit photo in Pixinsight as usual, but on final stage try to keep the image dark and not clip or compress highlights too much, dark image is ok. 2. Export as 16bit TIFF 3. Do final curves edits in LightRoom, enabling HDR mode. Both SDR and HDR versions can be made independently. 4. Export to AVIF. Mac/iPhone will show it correctly. 5. Publishing in LightRoom album also works fine (e.g. this is my DSO HDR album: https://adobe.ly/4cfEDGX)

Hello all I'm making a public discord revolved around astro photography with a goal of learning and growing community in a easy format and way where it's easy and compact to learn from each other and improve. Would anyone be interested in joining?

The first photo is my attempt and the second one is my end goal I got some data sets off of telescope live to practise processing I did a pretty good one for the rosette nebula but I'm struggling on this one (the cat paw nebula) and I can't seem to find a YouTube video that is good what I specifically need so if anyone knows a YouTube video that can help me or any tips that would be great. I use siril or dss for stacking I use graxpert and adobe photoshop and the files are halpha, OIII and SII
