Seestar S50 Image Processing - Getting Started With Imaging - Stargazers Lounge
November 29, 2025 - No matter how hard I try I just cant seem to grasp how to process images from the Seestar S50. All the tutorials seem to complicate or maybe it's just me. Looks like I will have to stick with images straight from the scope.😞

Thinking about a SeeStar S50 - questions about post processing
The RAW images coming out of S50 are different from what you're used to in "regular" photography. They need to be stacked and "stretched" to reveal the object in full glory. The most common free tool is called Siril. You can see the process and the final result here . And he shares the raw files so you can try it yourself too. IMHO, the stuff that is processed in the Seestar app and other mobile apps doesn't hold a candle to what can be produced using the more "conventional" processing tools. More on reddit.com

r/seestar on Reddit: Thinking about a SeeStar S50 - questions about post processing
November 11, 2025 -
I've been doing a little bit of "Landscape Astro" photography for the last 12 months. My rig includes a Sony A7II and Viltrox 16mm F1.8 lens (no tracking mount). To produce better images, this requires a lot of post processing.
I have been thinking of a SeeStar S50 as the next step up into the hobby, and to look deeper into our skies.
While I see a lot of images directly out of the camera/app which are pretty good, I am curious to understand how much better images can be made in external apps, processing RAW files.
Also, what external apps are people using? For my current Landscape Astro process flow, I use Sequator and Photoshop.
Thanks

r/seestar on Reddit: Post Processing Advice
March 10, 2024 -
What is the best way to do post-processing of Seestar images? Use the stacked image it creates? Or use the individual subs? (I'm guessing the latter).
Also, which is the best software to use. I have Siril and also DSS, though DSS is proving difficult to learn.
I'm new to photo processing...wish there a place to learn the ins and outs of what functions to use and when while using software. For example, you can surmise by my screen name I am a bowler and also a golfer...so when presented with a particular shot while golfing I know what to do and how...but with photo-processing, I'm a bit lost.
I've done some trial and error but want to get better results.
Any advice is appreciated. Thank you in advance and Clear Skies!

November 29, 2021 - Hi - With Fabio's valuable inputs, I have assembled a step-by-step approach to processing Seestar S50 automatic telescope subframes (if saved) in Astroart. This is it. This approach achieves a level of output not unlike that provided by the Seestar S50's automatic processing to yield its final image.

The script that covers Seestar needs is named Seestar_Preprocessing. Click on it and wait until it is complete. The stacked image is normally located next to your lights folder and the newly created process folder. It should be named according to the object photographed and the number of images stacked like for example: NGC_2175_268x20sec_T7°C_2024-03-07.fit.

r/seestar on Reddit: Best software to use with s50 raw data?
November 9, 2025 -
Hey guys
So I got the s50 and have been trying to figure out the best way to process images. I have Siril and used it to split the background and main subject with my photo of orion and Andromeda but they just seem to be lacking. I'm happy with the photos, but I have seen much better versions line.
Additionally, Siril didn't do an amazing job, where I ended up following a guide online (linked in this thread) using just lights and by the end, my photo was essentially pure white and looked ridiculous.
Does anyone have advice on what tools are best?

Siril is a great piece of software. You can achieve very good results with it from Seestar data but you need to do some reading around and practicing with it. I recommend the video tutorial linked below - it’s what started me off. Deep Space Astro (also on YouTube) has some great tutorials as well. https://youtu.be/lMoSAHOgbD4?si=7JNocsUgBvmI1XqC I’m sure somebody will recommend PixInsight or other tools but I would suggest you get an understanding of post-processing with Siril - you can always splash out on paid-for software when you have a better idea what you’re doing. Other software (free) which can be used together with Siril are Starnet++ (star removal) and GraXpert (noise reduction, background extraction). And as an example, here’s my most recent image (Andromeda) post-processed with the software mentioned above (plus a bit of Photoshop for final colour tweaks, and RC Astro’s NoiseXterminator plugin). Good luck.
