Over the weekend I got some good data on the Horsehead Nebula so now I have decent images of both of the big showy nebulae in the constellation of Orion. All data taken with my Seestar S30 Pro from my Bortle 7 backyard in Sydney, and processed in Siril with RC Astro, GraXpert and VeraLux scripts. Both images have about 4 1/2 hours of exposure time in them and I feel like they could both do with some more, but they'll do for now. Maybe I'll do a big mosaic covering both nebulae a bit later in the year when I can start imaging them before 2 am. #Astrophotography #Seestar #SeestarS30Pro #TMMT #ThirtyMillimetreTelescope #Siril #RCastro #VeraLux #GraXpert #SmartTelescope

Huh, I thought I'd already done about as good a job on the Helix Nebula as I was going to be able to do with the Thirty Millimeter Telescope, but increasing the total exposure time from 11 to almost 20 hours, doing a 1.5× drizzle upsample, and refraining from pushing the brightness so hard have together brought rewards. Maybe I should keep going on this even longer. #Astrophotography #Seestar #SeestarS30Pro #TMMT #ThirtyMillimetreTelescope #Siril #RCastro #VeraLux #SmartTelescope

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. #Astrophotography #Seestar #SeestarS30Pro #Siril #VeraLux #SyQon #ThirtyMilliMetreTelescope #TMMT

IC1805 / the heart nebula #astrophotography #astronomy #siril #ekos #IC1805

LDN1082, quite difficult to get right in postprocessing #astronomy #astrophotography #siril #ekos #LDN1082

The end result was still quite nice though and the Aurora was incredible! #IC434 #siril #ekos #astrophotography #aurora #northernlights

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. https://siril.readthedocs.io #Astrophotography #Siril #FOSS #OpenSource

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. 50% scale version in this post, full resolution (6047×3411) here: https://drhotdog.smugmug.com/Nature/Seeing-Stars/i-RXPkcWj/A #Astrophotography #ThirtyMilliMetreTelescope #TMMT #Seestar #SeestarS30Pro #Siril #SyQon #VeraLux

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).
