Right, this was a challenging image mosaic to process!
It the Rho Ophiuchi Cloud Complex, near the bright yellow star Antares (upper left) and Crab Globular Cluster, M4 (lower left).
It's a 4 panel mosaic with a grand total of 8 hours exposure time with the Thirty Millimetre Telescope, taken over two nights from suburban Sydney before the Moon rose. This would definitely benefit from a *lot* more exposure time (and darker skies) but this will do for now. All processing in Siril with SyQon and VeraLux scripts. It took a bit of trial and error to iron out the residual sky background gradients but I got most of the way there in the end. It's oriented north right, east left because it fits on computer monitors better that way.

Well this came out better than I expected. It's NGC300 as seen with just under 3 hours of total exposure time on the Thirty Millimetre Telescope (Seestar S30 Pro), taken from suburban Sydney (Bortle 7) while the Moon was up.
Galaxies are not what this telescope is best at, but I wanted to try this one anyway as I feel a personal connection to it. It was the first target that we pointed the first "Huntsman Eye" single lens prototype of the Huntsman Telescope at during our first observing run. It is also the official deep sky object of the Golden Dragon Chinese Restaurant in Coonabarabran, near Siding Spring Observatory.

And now the Prawn Nebula gets a similar treatment. For this one I had a little over 1000 30 second exposures in the bank, and put 600 of the best into the stack.

After much farting about in Siril I now have my version of the Lagoon, Triffid and Chinese Dragon nebulae. It's certainly different to the results from the Seestar app, and overall I think I prefer this version. Plus it's more satisfying doing it this way!
To get the best possible result I dug up all the data I had on this target (almost 1000 30 second exposures) and selected 560 of the best to stack together. Some were taken in Kurrajong with lower sky background but worse focus, while most were taken from Sydney with measurably more sky background (despite the light pollution filter) but better focus.

The Helix Nebula.
This is more of a target for bigger telescopes really, but I have been curious about what the little Thirty Millimetre Telescope could do with it. Between last night's data and a smaller stash I'd previously taken I put a little over 8 hours worth of 30 second LP filter exposures into the stack. All processing in Siril with SyQon and VeraLux scripts.
It would probably benefit from even more exposure time, but the Seestar was already well into the diminishing returns domain as it was and I'm not sure it's going to get dramatically better no matter how long I go.

This is the nicest photo I've ever taken of a bunch of dust.
This image of part of Corona Australis includes the Corona Australis Molecular Cloud, one of the nearest star formation regions to Earth.
Turns out this is a challenging target for the Thirty Millimetre Telescope, especially when the Moon is up! I put a total of 14.3 hours of exposure time into a 3 panel mosaic and I still think I need to revisit this target with some darker skies (and better flat field calibrations) to do a better job of it. I'm calling this a work in progress until then.

Meanwhile I've been struggling to get an aesthetically pleasing result out of this other bunch of stars, the Small Magellanic Cloud. Plenty of data (about 8 hours 20 minutes of total exposure time) but it can't massage it into a pleasing JPEG. Maybe I just don't like the SMC.

My god, it's full of stars.
M24, the Small Sagittarius Star Cloud, and neighbouring bits and pieces. Just over 4 hours 10 minutes of total exposure time over the last two nights with the little Seestar S30 Pro and its UV/IR cut filter. Not bad considered how irritatingly bright the Moon was being at the time. Processed in Siril with SyQon and VeraLux scripts.
I should have been using the light pollution filter under conditions like that, but I've already done all the big HII regions that are conveniently placed at this time of year so I've been trying to do stars and dust despite the Moon.

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.
