10" Dobsonian

Anyone of you bought a 10" Dobsonian, especially people around age 18-20? If yes how'd you manage to move the telescope to much darker places? Like I bought a 10" GSO and it's Incredible to Observe with , but handling it is Quite difficult... Anyone with same Experience? By the way this is the jupiter i captured , average seeing.

Built an iPhone-native live-stacking app after years of dealing with Windows + driver hell — TestFlight beta open, would love this community's brutal honesty

Long-time lurker, first real post. Hoping the mods give me a pass for self-promo because I think this community is exactly who I need to hear from.

After years of doing astro the conventional way — Windows laptops on the balcony that kept crashing, dedicated cameras with driver problems, endless cable management — I decided to find out whether modern iPhones could actually do live-stacking natively. Turns out they can, more or less. So I spent the past year building it.

AstroStackerPro: real-time live stacking entirely on-device, up to ~600 frames per session, IMU-based derotation using the gyroscope for untracked long integrations, on-board editor with denoise (AI, on-device), sharpen, light-pollution removal, and exports to FITS for those of you who want to take the stack into PixInsight or Siril.

Privacy: 100% on-device, no cloud, no analytics, no account.

Requirements: iPhone 11 or later, recent iOS.

Public TestFlight beta is open. One-person project, v1.0.1, definitely rough in places, and I am genuinely at the stage where real users finding the things I missed is more valuable than gold to me. So please be hard on it.

Honest caveat: for certain targets (deep sky, high magnification) you'll still want a tripod, a star tracker, or a dedicated iPhone telephoto — but I'm actively pushing to minimize the extra gear needed.

Best channel for detailed feedback is email at astrostackerpro@icloud.com, I reply individually.

Ho creato un’app per iPhone che permette di fare astrofotografia in modo semplice e smart, ma soprattutto direttamente dal telefono, così da smettere di trascinarsi dietro strumenti pesanti e delicati nel buio.

https://preview.redd.it/yozvvqod01bh1.png?width=1254&format=png&auto=webp&s=2fe3d03e6ae48848a06786bdc27fdac05b1859d8

Mi presento: mi chiamo Stefano e sono uno sviluppatore amatoriale che, con l’aiuto di Claude, ha sviluppato questa applicazione.
Faccio astrofotografia da un po’ di tempo e, per anni, la serata tipo è stata questa: il portatile che si blocca sul più bello, i driver della camera astronomica che litigano con il Mac e mezz’ora persa al freddo per far ripartire tutto, invece di guardare il cielo. A un certo punto, stanco di lottare più con la tecnologia che con il cielo, ho provato a mettere tutto dentro un iPhone.
È nata così AstroStackerPro. L’app scatta tante foto brevi della stessa porzione di cielo, le allinea e le somma in un’unica immagine, facendo emergere stelle deboli, nebulose e la Via Lattea dal rumore, senza fronzoli né apparecchiature complicate. Include anche un planner che mostra cosa è visibile durante la notte dalla tua posizione (Luna, pianeti, classe Bortle e copertura nuvolosa) e un piccolo editor per rifinire lo scatto.
Sono onesto: non facciamo ancora miracoli, anche se ci stiamo lavorando. Per il cielo profondo, un treppiede e un cielo abbastanza buio aiutano parecchio. Sto ancora sistemando molte cose e presto arriveremo anche su Android.
Questo è il link del mio sito, se vi va di dare un’occhiata: https://www.astrostackerpro.com/
L’app è disponibile gratuitamente in beta pubblica su TestFlight. Se vi va di provarla o di darmi un feedback, scrivetemi pure a astrostackerpro@icloud.com.

Untracked Milky way from a Bortle 5 Skies | 1500s, [Xiaomi 14T Pro]

[23 mm • f/1.6 • ISO 2500 • 15 s] × 100 Light frames + 250 Dark frames (25 min total integration time)

UPD: Reddit heavily compressed the image. For the best quality, download the image to your device and view it locally.

Stacked in Sequator.

Processed in Siril: green noise removal, background extraction, colour calibration, saturation adjustment, and starless stretching using StarNet++ to create separate star and Milky Way masks.

Denoised in GraXpert.

Finalized in Photoshop: final curve adjustments, saturation, colour calibration, and channel mixing.

Untracked, shot using only a smartphone mounted on a static tripod under Bortle 5 skies.

Shot on a Xiaomi 14T Pro using the main Light Fusion 900 sensor.

Congratulations on the winner of June's contest!

Hello everyone! Today is July the 1st, and that means that r/Astro_mobile wants to congratulate the winner of the previous month!

And 🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁🥁

u/AstrusOne! 🎉🎉🎉🎉

Your wonderful shot of M8 and M20 will be our next banner for a whole month.

u/AstrusOne is an owner of Vivo X300 Ultra, what is a dream setup for a smartphone astrophotography!

As a tradition, the word passes to u/AstrusOne:

"I've been involved in the world of mobile phone technology for a long time, and back in 2019 I started doing my first tests with them to see what they could do. With some models, with much smaller and less powerful sensors than now, I managed to take photos with the main sensor where the Milky Way and even M31 or the Andromeda Galaxy were visible. For me, that was already an incredible achievement. Then I moved on to astrophotography with a telescope, and a couple of years ago I started doing tests with the most powerful models of phones, taking pictures of the Milky Way or panoramic views of it. With the release last year of devices with teleconverters from the same brand and Zeiss lenses, I decided to apply the capture and processing techniques usually reserved for telescopes and cameras with powerful telephoto lenses to smartphones, and as you can see, it's looking promising. As a side note, I've built a small flat panel for using these teleconverters."

Thank you very much for that beautiful image! And thank you all for your attention!

See you next time ♥

M31

Hello! I would love to show you my picture of the Andromeda Galaxy. It was shot on my s22u and then processed in graxpert and SAS and then gimp. It's not the best, I know, but it's one of the first things I have shot.
