And the same images again, but with some basic post-processing applied to get rid of the ridiculous brightness gradient from millions of inner city lights. #space #astrophotography #seestar #astrodon #astronomy

Another successful overnight rooftop imaging run. The Moon is still very new, so I decided to image without the light pollution filter for a while.
Globular cluster Omega Centauri, Messier 24 (the Sagittarius Star cloud) and the Helix Nebula.

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.

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.

The Markarian's Chain - a stretch of galaxies, part of the Virgo Cluster.
ZWO Seestar S30 Pro.
160mm, f5.3, 1256 exposures of 30’’ - 10h 28'.

🗽 Despite not being in Western Australia, I imaged #NGC3579 anyway. This is about two hours last evening with the #seestar S30 Pro.
The field of view on that is quite big, so I could fit in a lot more. The actual target is the bright nebula at the top. The little nebula at center is NGC3572, sitting behind the open cluster Collinder 240. Finally, at bottom left is NGC3532 aka the Pincusion Cluster.
For comparison, the pincushion cluster is half again as large on the sky as the disk of the full Moon.
All of this is in the constellation Carina in the southern Milky Way. The carina nebula sits just out of view on the left.
As-is off the device.
