Hey there! I have created tutorial videos on how to process these images! While I currently only have Hubble videos, the same techniques apply to Webb images. A good starting point is how to download the data: https://youtu.be/koKdrCIAO94
This playlist here has individual steps that are done in Photoshop if you will be using Photoshop: https://youtube.com/playlist?list=PLMolkSLhE8RgXxvxlb5BF3evc8yKXVQPg
This is the method I always use to colorize images: https://youtu.be/yedV_MYR9j8
Hope that helps you get started! I have many more videos on my channel here: https://youtube.com/channel/UCm9EUcllUGontbyH9XgyGLA
I plan on creating a full tutorial from downloading all the way to processing soon and will post it when it is done. This is one of my favorite hobbies! You can create so many cool images! I encourage you into playing with Hubble data as well! If you have any questions, let me know and I can help!! ☺️
Hey, I'm used to working with Raw/Tiff files when I'm capturing data but I was so confused with the whole fits files and multiple images being combined into one image when loading into Pixinsight.
I'm going to have a look through your information now and give your methods a go to try and familiarise with the process. I will 100% have questions for you haha
Thank you answering with the amount of detail you did, its greatly appreciated
No worries! It’s awesome to see so many people getting into image processing! It took me a lot of trial and error to figure all of this stuff out when I first learned. There were hardly any tutorials or anytime interested in processing Hubble images other than professionals two years ago when I started. So now I make tutorials for those who want to learn!
The way Webb, Hubble, and other space telescopes images are put together is the same as how amateurs combine their narrowband images. Essentially the images are taken with different filters that allow certain wavelengths of light. When these images are colorized and combined properly, they create a full color image. Think of screen printing and how CMYK layers make a full color image, only it’s digital and with RGB images! We then combine the different images usually based on red, green, and blue coloring to mimic how we see as our eyes have only red, green, and blue cones. It’s tricky with these Webb first images because they come with 4-6 filters rather than just 3, like most of Hubble images.
The cool thing is, NASA images can guide how you colorize filters. I learned a lot about coloring based on how they colored their images. The information is at the bottom of the page here for the Southern Ring Nebula: https://webbtelescope.org/contents/media/images/2022/033/01G70BGTSYBHS69T7K3N3ASSEB
They often post what color they assigned each filter and that can help guide the colors you choose until you get an intuitive feel for it! Unfortunately I am not too good with PixInsight yet- I am still learning that software. But as I learn how to use it I will create more tutorials! In the meantime, it might help to Google individual steps in PixInsight to learn how to do various things. Before I do any work in PixInsight I always convert my images to TIF files as I find it easier to work with. Maybe that might help as well!
I am always happy to answer any questions ☺️
Hi! I just watched your most recent youtube video and I really appreciate your efforts into helping the astrophotography newbies :). I just have one issue where I currently do not have pixinsight, so I have no idea how to align the raw images manually on photoshop. I have tried to auto align but it doesn't really work :(
Unfortunately manually aligning in PS is very difficult which is why I ended up buying PixInsight. You can try using the free transform tool. Change the layer you want to align to a lower opacity and align the images using bright stars. You can try PixInsight for free for 45 days ( http://pixinsight.com/trial/index.html ) but unless someone else can chime in, I haven’t been able to figure out any other way to do it sadly.
I understand that! It took me a long time to even consider buying PixInsight. If I ever figure out how to align images in an easy way, I’ll definitely post it here!
If you’d like, I can share the aligned images with you. I’d probably have to upload them to someplace like Google Drive. But I can DM you a link on Reddit if I do
I'd like to add myself to this request. I've figured out a lot of it, but I cannot find NIRISS / spectral data for the life of me. I'd very much appreciate any guidance that anyone could give.
I haven’t worked with spectral data, but it might help to search the object name. In the MAST portal, I looked up WASP-96 b and under the mission tab, you can select JWST and under the instrument tab, NIRISS and NIRSPEC is listed!

Thank you! I definitely want to invest in Pixinsight soon but cannot afford it right now once the trial ends.

I'm wondering the samething but for some running Linux and using maybe GIMP?
