Hello and welcome. I'd like to ask everyone who already did or knows an alternative way to process Galaxy images without Photoshop.
Does anyone know how to process any Galaxy images without using Photoshop? For me to process any images like that requires me to buy Photoshop, which I can't do. Alternatively, I could use as well gimp but then it's a bit complicated for me.
So, does anyone have any suggestions? Like what to do? I'm trying to follow the galaxy processing from the deep-space astro channel, but there is something that I can't use, and that is Photoshop.

okay, I have some idea:
1. Autostretch
2. ColorCalibration, select a small area with few stars, press "use current selection", then, press "background neutralization"
3a. Background Extraction, just put some sample boxes around the object(s), not on them, and also try to avoid putting them on stars; you'll need to experiment with the settings to get the right results for your specific image; and I usually never would use Division, but that's only me.
3b. just in case, I would do another ColorCalibration after that, but this is optional
4. go back to Linear
4b. from here, you can either stretch the image, crop out the edges, maybe add some saturation, and call it finished, or you can go further with the next step
5. go to Image Processing –> Star Processing –> StarNet Star Removal, check the "Pre-stretch linear image" box and the "Generate star mask" box; press Execute; this will separate the stars from the deep sky object(s)
make sure you know your working directory (the blue icon at the top left, with the house; this will be the place your files will go)
6. you'll be left with a Starless image; proceed with stretching as much as you think fit (you can find the stretching processes in the Image Processing menu, at the top)
6b. increase/decrease saturation if you want
7. save that image as 16 bit TIFF
8. go to Image Processing –> Star Processing –> Star Recomposition; for the section labeled "Background Stretch Parameters" open your starless image, and for the section labeled "Star Stretch Parameters", use your Stars image; now, you'll see a Starless image show up with a few stars; if you want, you could increase the Black Point of the Starless a little, but now you need to stretch the stars; stretch the stars carefully; you'll see the stars pop out now; now press Apply on both sections
10. close Star Recomposition, and crop edges if necessary; save completed image as Jpeg, or whatever you want
this should be it
plz understand that my Siril workflow is basic and my memory is rusty; I haven't used Siril in months

e do u have a similar idea of what to do In Sril?
Like Step by step. this is an absolutely great Siril tutorial. https://www.youtube.com/watch?v=hIhgS3bvOy0&t=1296sonce you save the Siril processing as a 16 bitt Tiff, you can load it into Affinity, which is very very similar to Photoshop. Affinity is excellent software for Colour and general image adjustments. once a year in the annual sale, its as low as $50 for a lifetime, and no additional subscription fees.

RANT ALERT!!!!
I really wish that a lot of these tutorials wouldn't be so software specific. Most processes can be described in general terms. That way you can apply the principals in whatever software you are using be it GIMP, Photoshop, Affinity Photo etc…

It's not that you have to purchase it that is troublesome; it's that you have to rent it every year, which gets expensive. That's why Affinity is excellent, buy it and you own it. And as mentioned above, it's available for excellent sale prices during the year.

There's no need to rent Photoshop at all, period.

I'm not sure why everyone is so negative about Photoshop. Is it free, No, but it's great software and for a lot of imagers it's the final step. I've used PS for almost 20 years, and yes you do need get a yearly subscription now but is $120 a year really that big of a hit, that gets you Photoshop 20Gb plan plus Lightroom, well worth it, I think. Edit: Also, if you can find a hard copy of Photoshop CS5 or CS6, that's a onetime purchase and pretty much dose everything Photoshop CC does.

I think a lot of people feel as I do because there are alternatives that are much cheaper or free. $120 might not seem like much but it does add up. I also think it's a bad direction for software marketing in general. It just rubs a lot of people the wrong way.

Affinity is a layer based editor just like Photoshop, and you buy it once and no subscription.
my version of Affinity cost me $50 in the sale, and has cost me absolutely nothing since.
the James Ritson Astrophotography Macros, are designed by Affinity Product experts, and are available for free download.
anyone who is familiar with PS can easily transition to Affinity, because the functionality is very very similar.
I say all this because I feel that Affinity was the best $50 I ever spent, on anything to do with AP.

I’m giving Startools and it’s developer Ivo Jager a plug
It’s been around for 10 years or so but rarely mentioned on Astro forums nowadays
I’ve used it for 6 years now and happy to keep using it
Very powerful and easy to use , no complicated curves , layers or levels to adjust and no trial and error either
It mathematically processes every pixels on the fly to achieve the best SNR outcome in your image. It time travels back and forth behind the scenes and knows exactly where your image is in regard to Signal.
It removes all the guess work , gives you a clean base line image in which to enhance detail without propagating noise.
Great for both beginners and advanced imagers like myself

I've never used photoshop to process my astro images. PixInsight is much better, especially if you learn to use it and not the myriad of scripts being pushed.. Good luck. This hiobby isn't for everyone as it's not free or cheap .

This hiobby isn't for everyone as it's not free or cheap . I agree 100% . Software and learning to use it is such a huge part of the hobby these days that trying to save money on that is almost as bad as trying to save money on your mount. PixInsight is the gold standard for a reason. These days I use if for 95% of processing. I only go outside of it where I need to do something specific, usually something that requires a user's eyeball and brain. For that PS and a couple others can be very useful. PS also has some plugins that can occasionally be useful, such as Topaz, to name one. So PS is not required and does not reside in any specific part of the workflow or is even used at all on some images. Rather is is used when I need a specific tool that is not present in PixInsight.
