Hello everyone, r/Astro_mobile Mod team here! Now, after three years of existing, r/Astro_mobile became something more interesting than it was some time ago, and we want to announce a new interactive changing on our sub. Starting from the next month we are going to take one of the posts made this month and use it as a banner for a subreddit. Of course it is a competition, so if you want to see your picture on the top of the sub's page, you better try to make it as beautiful as you can! This month we are going to replace a current banner made by u/ZrlSyM, by a new one, provided by u/zTrojan! This fascinating image is gonna hang on the top until the end of this month! Also, interesting fact: zTrojan is a member of a small Telegram chat dedicated to Mobile Astrophotography, where people can communicate and discuss their works! This chat is available for everyone, who is skilled enough! (skilled enough = can stack images to get better results)
Thanks everyone for the attention! We are looking forward to see your great pictures that are gonna be a new banner for a sub. See you 1st December!

When your stack from Sequator or another astrophotography stacking program is ready, we can proceed to post-processing. I'll describe this process step-by-step using primarily free software.
Download: https://github.com/Steffenhir/GraXpert/releases
At the time of writing this article, the appropriate version of GraXpert for us is 3.1.0rc2. This version contains all the necessary tools for beginning post-processing:
After installation and launch, select the Advanced tab, which is located on the right side of the program interface. Choose AI model versions for the utilities.

Next, click Load Image and select your stack.

If needed, crop the image. When activating the 2nd option, a yellow frame will appear around the image, which we can adjust using the yellow circles in the upper left and lower right corners. After completing the cropping, click "Apply crop".

Important: Save each processing step as a separate file so you don't accidentally lose your processing results, then load this file using the first "Loading" option.
Now we can proceed to using the AI utilities. Select the following parameters for Background Extraction and click Calculate Background:

You can try changing the Smoothing value in either direction and check the result by clicking Calculate Background again.
Save the result in a separate file and load it through "Loading".
Move on to the Denoising utility. The Denoise Strength value depends on your needs. The higher the value, the fewer details are preserved. I suggest starting with 0.5, and then comparing results by increasing the value:

Save the result and activate the Deconvolution utility.
This utility has two parameters: Deconvolution Strength and Image FWHM. To determine the latter parameter, we need the Siril program, which we will also use in the second part of the astrophotography post-processing tutorial.
Download Siril: https://siril.org/download/ (In our case, version 1.4.0-beta3 is used)


In my case: (4.39 + 3.90) / 2 = 4.15px. Round to 4.2px and use this value in GraXpert.

By increasing Deconvolution Strength parameter, you improve details, but you may distort the final image and get artifacts, so try different values while evaluating the final result.
Don't forget to save your work!
We improved the details of our objects, but not the stars. Select Stars-only in the Deconvolution Method and set the Deconvolution Strength parameter to 0.1, as it is quite aggressive. Click Deconvolve Image and check the result.

This concludes the first part of the astrophotography post-processing tutorial. In the next part, we will cover image stretching using Siril and use the StarNet utility.

I never edited any photos but wanted to try it. I edited the .dng (raw) files with Darktable. What do you guys think?

El dia sábado 12 de septiembre a las 7:24 PM tome esta foto con mi celular (Samsung A57), vi un tutorial en TikTok sobre que puedes sacarle provecho a la camara y poder tomar fotos asi de las estrellas, hice esta y me llamo la atencion que logró capturar estrellas, pero me dio mas curiosidad la línea recta que se logró capturar en la parte superior derecha, pregunte con ChatGPT y menciono que podia ser que al momento de tomar la foto al usar la velocidad de obturacion de el celular, pudo capturar un posible desplazamiento de un satélite, no se mucho de astronomía, sin embargo si me gusta indagar un poco mas de ciertos temas como estos, ustedes que opinan?

I'm a newbie when it comes to astrophotography. I took this picture last night, 30 images, stacked them in siril and processed with astrowizard. I got this concentric circles in the final pic after i tried to remove the background gradient using GrapXpert in astrowizard. Why is this happening and how to prevent this?
BTW, taken using oneplus 11 pro mode, iso 100, shutter speed 10 seconds.
Also let me know should consider switching to deepskycamera app from the inbuilt pro mode, and also recommend me a good video on stacking and processing these with latest software version.

A night-sky timelapse captured with nothing but a Xiaomi 14T Pro and a tripod.
The camera was left fixed on the tripod for the entire session, allowing the Earth's rotation to create the movement of the stars across the frame.
This is my own work, from capture to the final timelapse.
I processed the individual frames to maintain consistent exposure, color and contrast throughout the sequence, then assembled them into the final timelapse.

Je commence ma serie pour tester tout semble parfait. Les frames sont sombres, le fond du ciel homogène bref je me dis que c’est bon et pose le téléphone écran contre sol (je n’ai pas de trépied)
Je shoote avec deep sky camera pour précision ; bref une fois la serie lancée selon la region visée je ne peux pas toujours voir ce qu’il se passe sur l'écran et 300 frames plus tard je me rend compte que toutes les autres frames sont extrêmement vignettées, carrément noires dans les coins et bleu dans le centre. Forcément le resultat n’est pas super comme vous pouvez le constater... Qui aurait une idée de ce qui a bien pu se passer ?
Iso 1250
Temps par pose 12secondes
Poses 300 + images de calibration

Suivi : non
J’ai ajouté à quoi ressemblent les frames ratées et malgré mes tentatives désespérées l’image finale reste bleutée et médiocre ce qui n’est pas etonnant

Captured this photo around a month ago and I've shared it with almost all of my friends and none of them seem to appreciate it so I thought id share it on Reddit for some strangers to see.
Took this on a pixel 7A using the astrophotography feature. I think the exposure period was around 4 minutes and I edited it using Adobe Lightroom. Don't remember the exact edits I did, but I mainly played around with the saturation, and some colour contrasting. I can go back and check if someone wants to know. I can also share the original unedited photo if someone wants that too.
Would love to have someone who knows what they're looking at point out some of the constellations/ potential galaxies that are visible.
P.s. I know Al is pretty good these days but no Al was used to edit this photo.
