This work is based [in part] on observations made with the NASA/ESA/CSA James Webb Space Telescope. The data were obtained from the Mikulski Archive for Space Telescopes at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-03127 for JWST.

Great fun, Nico, thank you! I'm unlikely to buy either a mono camera and filter wheel or a James Webb Space Telescope in the near future, so this scratches that itch very nicely.
I thoroughly enjoyed your videos! Best astro presenter on YT for me. I really love your pacing, energy and dedication.
Thank you Nico, did the exact same steps and ended up with a great result, very different from yours. Never expected I would be able to do this so fast. So now my next steps of course are learning how to take the data from MAST and getting all this aligning and resizing etc done.
I use the RGB Composting in Siril to take the 3 channels and combine to get a full color image. You can do the curves/GHS on the combined or each channel separately. GIMP can still be done after if you need too.
Thanks for prepping the data! Great demonstration of how useful these two Open Source packages are.
I really enjoy your SIRIL/GIMP videos. I use these two processing softwares and learn something new from each of these videos. Thank you for taking the time to put these together. Much appreciated.
Always a delight following your videos
Many thanks Nico, your videos make us feel that very difficult and beautiful projects look feasible
Your enthusiasm is contagious, great video, great image, thanks for sharing your knowledge with us.
Thank you very much Nico for sharing your work and making it available to those who enjoy this hobby. I followed your instructions and achieved an excellent result, up to my expectations...!!
Awesome😊👍 thank you for sharing this knowledge
Thank you vm!
Thank you very much, i've been searching for such tutorial for many consecutive days, combining jwst data with free software, Great video !
Great video!
Thanks, going to have a go at this as I've just discovered Siril 1.2.0
I like using Gimp. Excellent video!
You are great ❤❤❤
Hi Nico: Love your tutorials...
Legendary tutorial! Fun fact, GNU is a recursive acronym that stands for "GNU's Not Unix" and it's pronounced "guh-new". Gotta love those 80's software guys.
Hii friend pls reply i have a request for you can you pls make video on this tutorial in photoshop for this data and thanks for giving data
Nico....Thanks for your smooth, calm approach to instruction. Your tutorials are easier to follow than most, and you never talk down to your audience.
I'm trying to learn Siril so I can get more out of my tiny SeeStar images. It appears that there's not a lot to work with and that the noise level is quite high on SeeStar image files. As a longtime pro newspaper/magazine shooter, I'm very familiar with basic Photoshop functions, but I've never needed layering or technical color tweaks. If you shoot right, the image doesn't need much... maybe a touch of saturation, contrast, and sharpening before being sent to desktop for printing prep.
Anyway....Siril covers all the stuff I never had to fuss with.
Finally, after some backstory, does Siril need some plugins to add "punch": noise removal, sofisticated sharpening, background evening, star bloat reduction, etc? Or, is the jump to Pixinsight needed for more image manipulation? Thanks for your thoughts, Michael
Hi Michael, Siril has some good tools for working with stars including star reduction, fixing star shape, etc. This video by Deep Space Astro covers a lot of the options: ruclips.net/video/VNAcOcpubgQ/видео.html
It also has a good background evening tool in ‘background extraction’. I would suggest using it first thing and turning down the smoothing to around .3 for best results.
For selective sharpening and noise reduction, I’d suggest Photoshop. Specifically, high pass filter with masks and overlay/ soft pass blend modes for sharpening and the noise reduction options available in the adobe camera raw filter.
Cheers, Nico
Very helpful Nico, thanks so much. I've still got CS6 on my laptop and desktop. Will look for all your fine work! @NebulaPhotos
Hi Nico, great video as always!! Is there any chance of getting a follow up video the "boring hard stuff" you mention at the start? Ever since the JWST released the fits files I've trying to edit the Pillars of Creation by following your JWST Carina Nebula video, but i haven't managed to get past those first hurdles with the different sizes and alignment. Thanks!
Yes, I’d like to, but before I do I want to talk to the Siril developers and see if there is any way they can make the process better in the next version. While the JWST files now open just fine in Siril as mentioned, I was crashing the program when trying to align images of different sizes. Not sure if this is expected behavior. I’m going to do a little more testing to see if it’s just on Mac or windows too, and then write a bug report and hopefully get it worked out soon.
Appreciate you my friend. Nico, when I bring the TIFF files in the automatically stack. How may I prevent such an event?
Which part of the tutorial is this happening at? In gimp, I chose open as layers… and picked the three tiff files I stretched in Siril.
@@NebulaPhotos Opening the files to bring in to GIMP. You added them in individual picture masks, while mine added all 3 together so there was no individual opportunity to edit them apart. Tried several times and they always camer as one. Thinking something is set incorrectly. Using the windows 11 64 bit version.
Bringing the original saved TIFF files into Gimp. You had 3 individual files. When I brought them to Gimp they were all 3 combined. Seems a mistake.
@@jimmydingo4752 Weird. Workaround: open each one separately. Copy - Paste them in (each time you copy paste you will have to make the floating pasted layer into a new layer). Email me: nicocarver at gmail dot com if you can't get it working
@@NebulaPhotos I discovered my mistake Nico. When I opened the files I overlooked the "Open in Layers" selection and just opened, which added the photos together as one. Apologies. Back to the tutorial.
Is there any way to actually register/align JWST data in Siril? Every time I've tried it just can't seem to do it, and there's no way I'm doing it in photoshop manually
I'm still in communication with the developers about this. It works with some fields, but if there are too many bright stars with black cores it seems to fail as Siril star registration doesn't know what to do with those black cores. Maybe there will be a fix in a future release.
Ok interesting, thanks for the response!
How do I fix the stars, they are clipped to black.
Ah, sorry, forgot about that. Assuming the only thing completely clipped to black are the star cores, you should be able to use: Colors > Map > Color Exchange and just 'exchange' all black pixels for white pixels. I found after doing the color combination of the channels, that my star cores were no longer black but a particular color, and that process should work the same way, but just use the eyedropper to sample that color, and replace it with white
@@NebulaPhotos Thanks!
Can you capture eagle nebula , bodes galaxy , Whirlpool galaxy
Yes, are those requests for videos?
How can we share our results ?
You are free to share them wherever you like. If you'd like me to see, you can email me 'nicocarver at gmail dot com' or message me on instagram.
How to find it is a bit difficult.
Very difficult to find what to download and from where. Please guide me.
I have been searching MAST. Everything looks beyond my mental scope. Can you please guide me step by step.
For this particular object, I put the link in the description to download the already registered files. If it’s something else, you have to know what you are looking for. My original video on JWST processing has a bit more on using MAST advanced search, but again it only really works if you go in already knowing what you are trying to find. Otherwise there is way too much to sort through.
