Una supernova, una única estrella, en el último instante de su existencia, llega a iluminar más que toda la galaxia que la vio nacer.Una fuerza colosal.
➡️ El 8 de julio de 2026 descubría Patrick Wiggins la supernova #SN2026sqf.
➡️ Juan ( @astrojaya4 ) alertaba a un grupo de amigos sobre la posibilidad de fotografiarla.
➡️ Miguel ( @astronorte_com ) desde el Observatorio El Rito realizaba serie de capturas.
Por acá lo hemos editado con #Siril.

So in the night I swung my ass on the bicycle and went to a place outside the village to do #astrophotography with no experience at all. After wasting a lot of time I made a single series of 100 shots. My first stack with #siril was a bit of a pain in the ass, but here it is. My first and simple stack without any big corrections.
I thought it will be much worse, because I just made the ‘lights’ shots, everything else had to be done today 😅huge thanks to @latuernich and @mechanical0815
Without your advices I would have wasted a night out in the dark 😬For the next try I have a bit of more orientation what and how to do

Yay, first time done astrophotography using Siril for stacking and processing the images.
I took the pictures in my garden not caring about the trees and other stuff, just wanted to figure out how the processing in Siril works. Lights, darks, flats and biases, got them all.
The result: it works fine! I am quite happy, it's quite okay for the first time.
But maybe someone can help me out and tell me where those bright spots in the corners come from. Is it because my flats were not good (white paper against the window)? Or was it caused by surrounding light? Curious to know...

As an astrophotography newbie I have to give the Siril astronomical image processing software an enormous amount of credit. Not only as a great example of free open source software that offers a genuine alternative to expensive commercial apps, but also for the quality of its documentation.
There's no "just ask questions on our Discord server instead" here! There is comprehensive written documentation online and it goes well beyond listing each function, it goes into detail of when and why to use them, how they work, and how to get the best results. And, if that's still not enough, you can buy the book! The lead developer has produced a 200 page A4 lavishly illustrated glossy guide book.
My copy arrived today, and I plan to pass the time waiting for clear skies by reading it.

That's better. I'm going to call this done now.
"Eta Carina in Context", all shot with the Thirty Millimetre Telescope (Seestar S30 Pro) from suburban Sydney (Bortle 7), mostly during full Moon, using the built in light pollution filter. Processing in Siril with SyQon and VeraLux.

Next I decided to go back to the third target I ever pointed my Seestar at and reprocessed the data to see what difference 3 weeks of additional experience with Siril made.
This is the Prawn Nebula, IC 4628. The results are clearly different, though I'm not sure I could say the new version is definitely better. It might be best to tweak the stretches to get something in between the two, I think.
Interestingly on this image I found SyQon Prism Lite just wouldn't stop deleting faint stars along with the noise even with the strength turned way down, so I went back to VeraLux Silentium and it did a much better job of preserving faint stars while still doing a decent job on the noise. A reminder that it's sometimes worth trying several of the available algorithms/plugins/scripts to see which gives the best results on a given image.

In the absence of new images I'm continuing to rummage through my Seestar reject bin to see if the fancy machine learning algorithms can salvage something from the less than ideal data sets.
This time it's a couple of reflection nebulae, the Blue Horsehead Nebula IC4592 and Sharpless 1 SH2-1. Both definitely needed a lot more exposure time and the results here still show it, but the processing has done an impressive job of pulling an image out of the noise.

With little chance of any clear night skies in Sydney for at least the next week I've resorted to having a go at processing some previously taken data that I didn't have much hopes for.
This is the Helix Nebula, NGC 7293. While it's big as far as planetary nebulae go it's still a rather small target for a Seestar S30 Pro, and I also didn't have as much data as I would have liked (408 30 second exposures from two nights), so I really threw everything I could at it when it comes to processing.
Drizzle with a 1.5× upsampling in Siril, SyQon Parallax and Prism (free Nano versions) for sharpening and denoising, and Veralux Nox, HyperMetric Stretch & Revela for residual background removal, dynamic range compression and local contrast enhancement. I'm honestly amazed it came out this well, but think all the credit should go to the seriously impressive free software I used to do it.

All those images are done processing now so here's the result from last night in suburban Sydney: the Lobster and Cat's Paw Nebulae.
Just over 8 1/4 hours of total exposure time on the Seestar S30 Pro with light pollution filter, Bortle 7 skies + some moonlight, processing in Siril.

And here is the end result: The Fighting Dragons of Ara.
This was definitely undercooked with just the images I took on the 12th June, but with the addition of lots more data from last night I'm happy with this now. In the end I had a total of 998 30 second exposures from the Seestar, 858 of which I allowed into the stack for a total exposure time of 7 hours 9 minutes.
Shot with my little Seestar S30 Pro in suburban Sydney using the Light Pollution filter, and processed in Siril with a mix of built in functions and VeraLux scripts.

As someone pretty new to astrophotography I've got to say that the new VeraLux Siril scripts by Riccardo Paterniti have been fantastically useful for me.
I've been happy doing preprocessing using built in Siril functions. 1st order polynomial background subtraction on the individual exposures, registration, culling bad exposures, stacking, photometric colour calibration, that's all good. Then comes the processing of the stacked image, and I'd be a bit lost without the VeraLux scripts.
VeraLux Silentium for noise reduction, then back to Siril built-ins for a bit of deconvolution sharpening, VeraLux Nox to remove any residual background, VeraLux HyperMetric Stretch for dynamic range compression, VeraLux Revela to add some local contrast back to the details, then VeraLux Curves to fine tune the tone mapping. Maybe a final tweak to the histogram using the built in tools, then I'm done.
At most steps I only feel the need to make fairly minor adjustments to the default/automatic parameter values to get the look that I want.

The Seestar reckoned it got 310 acceptable 30 second exposures before it got completely cloudy. When I reprocessed the data in Siril I was a bit more fussy and only included 224 exposures in the stack, just shy of 2 hours total exposure time.
I like the result, but do feel it's a bit undercooked. It would definitely benefit from adding at least another couple of hours of exposure time. I'll do that, but will have to wait until the weather is being more cooperative again.

OK, that turned out pretty well!
This was just under 4 hours worth of images of the Eta Carina Nebula, processed in Siril. Not bad for a 30 mm aperture telescope in an urban location.

I've now reprocessed the other H II region images from last weekend. I'm still learning how to use Siril, but I'm getting there I think. I'm finding several of the Veralux scripts very helpful.

First attempt at reprocessing images from the Seestar S30 Pro smart telescope, using my Prawn Nebula data from Friday night.
The first image is processed fully automatically, by the Seestar itself, and the second is my manual reprocessing using the Siril software on my computer.
I'm still impressed with how good a job the smart telescope is able to do in real time. The results make for a great live preview and are honestly just fine for viewing on small screens. If you have the option it is definitely worth the effort to reprocess the data on a computer, though.

#astronomie on continue avec l'image de NGC4565 dite galaxie de l'aiguille (c'est une galaxie spirale vue par la tranche qui donne cette barre noire sur le bulbe) elle est pas mal non plus même si le suivi est un peu moins bon (étoiles légèrement ovales) j'ai du faire une déconvolution avec #siril pour améliorer un peu la chose. On voit une petite galaxie spirale à gauche NGC4562, les deux se trouve à un peu moins de 40 millions d'années lumière!
