End-To-End Processing in PixInsight - My Photo of the Dark Scorpion Nebula
I finally processed my image of LBN 788, the Dark Scorpion in Taurus! After spending a week under dark skies, I collected nearly 18 hours of data with my Celestron RASA 8 and ZWO A...
Ottimo lavoro
You are great…. Please consider less coffee.
we're astronomers, we don't sleep...
I had to go back and look at my Scorpion image and I can now appreciate those structures too. Thanks.
Interesting and informative. There are so many ways to use PixInsight and it was nice to watch your approach so I can add to and experiment with my workflow. Gorgeous editing.
So, like..... not a tutorial..? Uh...yeah.
Please make a detailed processing of the LRGB+Ha galaxy. Thank you in advance.
thank you, it is one of the (many) videos in my pipeline
It looks relatively advanced. I didn't even know there was an HDR compensation process. Maybe it's newer than the pixinsight version I'm using. Maybe it can help with my coma cluster of galaxies. Or M81 galaxy. It's good to see a different way to process images.
HDRComposition is not new! You can find it under processes / integration
A very informative video. Thanks. What is the software you are using at the 10 minute mark?
I'm glad you think so! It is Aladin Lite (the web version) >> https://aladin.cds.unistra.fr
@the_space_koala Thanks - Much appreciated.
Are you married? Just teasing. Thanks for the video.
happily married
I absolutely love the results of this super image! Congratulations, Luca!! For what it’s worth, I leave “unscreen stars” unchecked for linear images. According to RC Astro, “If generating a star image from a linear image, don’t select the Unscreen option, which is for nonlinear (stretched) images. Simple subtraction is the best method for star extraction with linear images, and will result in the best star color accuracy.” Just a small, potentially helpful tip? Keep up the amazing work! 😊
thank you, that is a valid point. I didn't actually use the stars that had been unscreened from the linear image - as I stretched a copy separately and unscreened those. But you are right as a matter of principle I should disable that!
Great Job!!!!
Hey Luca I met Làszló Francsics here in the U.K. for Practical Astronomy Show (PAS) , he brought his work of art solar scope , be cool to see a video of you demoing it 👌🏻
hi, I am definitely excited to get a chance to try out the Soleye, and we are working on making this happen this spring/summer, fingers crossed! :)
@ fab , they are a lovely couple, I might have to start saving for the 6 or 8inch unit , although the sun the uk is a bit of a rear sight 😬🤣
It's mesmerizing to watch the process. Even with imperfect data... or maybe especially with imperfect data? It's good to see a non-perfect scenario (at least every once in a while) where it's just gotta be worked on a little bit. I'm so glad there are channels like this one, so that I get to see stuff like this that I might not otherwise be exposed to.
thank you for watching :)
Great video, so can I ask you (my second favourite lady, just behind my granddaughter) is there “one” particular filter that brings out the best in galaxies in a colour camera (533) …?
thank you, I do not believe in using any sort of magical filters for broadband. If you live in a place that uses old-style (orange) sodium lights you could benefit from a light pollution filter, but most places have switched to LED so you lose a lot of nice color information with very little benefit. Make sure you use an UV/IR cut and you're good to go
You amazing Luca 🥰
Good job!! The pic looks very nice... Remember back 25yrs ago, this kind a quality would be only from big professional facilities, using equipment for millions.
Helpful hint while using MultiscaleGradientCorrection...uncheck the "Show gradient model" option before running it on your preview, and it will show you the results on the image. 🙂 You can also do a second preview and run it with the option ticked, so you can see both at once. Sometimes, I do multiple previews so I can see which settings work best for my image. Your image looks fantastic, by the way, and I look forward to trying some of your processing techniques on my images! I'm gonna go follow you 9n Astrobin now! 😄😅
thank you very much! I wanted to see the gradient though! But yes 2 separate previews would work too, thanks! :)
Great video thank you Luca. I too as a Pixinsight novice found it difficult to keep up with but will listen again at lower speed. I work in television and often find that YouTube videos have been made without enough attention paid to audio levels. Yours are quite low. The advertising around the video blasts out and often gives my long suffering wife a bit of a fright at the jump in levels. Keep up the great work. Your intelligence and knowledge shine through your videos.
thank you very much for the feedback, Keith. You're not the first person to tell me the commercials are louder but strangely, this is not the case for me when I play it. I wonder if it is country specific on youtube (?) - I'll look into it!
it seems like a lot of people complain about this online - it could be related to stereo vs. mono or 5.1 vs not. may I ask what country/region you're watching from? I'll try to test using a VPN because I really don't get this issue on my side
Just breathtaking 😍! I even went over and looked at it on astrobin and there is nothing, really NOTHING to complain about! But it might take a few days of not looking at it until you can really appreciate what you have accomplished 💪👍🤩!
thank you so much Stefan for saying that!
Very nice video and image. I wish I had data as "bad" as that more often! As always, lots of useful ideas and tips.
Haha thank you! I know it wasn’t objectively bad, but then again I realized it’s mostly pointless to shoot from home so I almost always go to dark skies
@the_space_koala Yes, I'll definitely be making the 28-hour drive to Death Valley again. (Not my closest dark sky area, but far less chance of clouds there.) Thanks for the comment about dark nebulae/no filters. At that point I paused the video, took the filter off one of my telescopes and pointed it at a dark nebula during the total lunar eclipse. Might as well make use of the couple of hours of darkness!
@64gkb that is so funny about shooting during the eclipse - so lucky. We have one in September that is visible from Switzerland, but super low on the horizon
@the_space_koala The gold medal would go to someone who imaged a DSO during a total solar eclipse.
