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.

The Iris Nebula (NGC 7023) during the June heatwave in northern Germany. This reflection nebula is located about 1,300 ly from Earth, where a bright star illuminates the surrounding dust.

This image was created over 4 consecutive nights from Bortle 5 with a total exposure time of 5 h 21 m 30 s (643 x 30 s). For more information see: https://www.picturavis.com/picture?/487/category/37-astrophotography

This is a section of the emission #nebula #IC1396, including the Elephant's Trunk Nebula (#IC1396A). It gets its name from the prominent dust forming a trunk-like shape.

This image was created from 228 × 30 s (1 h 54 m) exposures from Bortle 4 with a ~5% moon below the horizon.

Processing was done in #Siril with the help of #GraXpert, #StarNet++ and #VeraLux StarComposer, as well as #GMIC in #GIMP.

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.

Due the bad weather a new composing of my #M31 shot from last year September with my #dwarf3.
Mosik of two parts with total 353 pics, 30s 60gain Astro filter.
STacking in #siril with the #naztronomy script , removing stars with the #syqon starless script, and more processing with several of teh #veralux then the final tuning in #dxophotolab and #DXONIKCollection
Finally some nights with clear sky´s and I could let the #dwarfmini do for what he is made. Then it tooks me some time to find the right process to get the best out of the shots.
But thanks to the hints found from the community and #dwarfvision I found a way works for me. So many thanks to the creators of the scripts.
Prozessed in #siril with the script from #naztronomy and #veralux
VeraLux HyperMetric Stretch additional some color fine tuning with #luminarneo
Endlich ein paar Nächte mit klarem Himmel, und ich konnte den Zwergspinner mal so richtig in Aktion sehen. Dann brauchte ich etwas Zeit, um die richtige Bearbeitung zu finden und das Beste aus den Aufnahmen herauszuholen.
Dank der Hinweise aus der Community und von #dwarfvision habe ich eine für mich funktionierende Lösung gefunden. Herzlichen Dank an die Ersteller der Skripte!
Bearbeitet in Siril mit dem Skript von Naztronomy und Veralux. VeraLux HyperMetric Stretch, zusätzlich etwas Farb-Feinabstimmung mit LuminarNeo.
