This tutorial shows and explains why using star removal (starnet++) in astrophotography image processing is not only a MUST but incredibly essential in being able to maximize the data in your astrophotography images! It focuses on hot to use Starnet++ standalone freeware which removes stars from your astro-images using a neural network algorithm.
The power isn't just producing a starless image, but being able to process your stars like never before and your nebulosity like never before separately and then combining them back together for a stunning result!
This is part 1 and focuses on the actual usage of starnet++ and how to make a star only layer and nebula only layer and be able to rejoin them back together EASILY. P2 will focus on nebulosity processing and star processing (including some star minimization).

If you're at this stage of astro... you should be sure to save this vid to a play list so that you can come back easily. I have had to come back several times because I did not remember the steps. I just used this vid for the 3rd time and my results keep getting better and better. Thanks again! This is indeed valuable info and it's presented very well.

Sometimes we search for weeks for a source that will answer a specific question or set of questions. When we FINALLY find the answer it's like a light from heaven. I followed your steps and successfully made my 1st starless image. You nailed what I was seeking to learn and did so at a pace that made it easy to learn from. Thanks for the vid! You just leveled up my processing game.

Really nice technique Ed. I usually select color as the highlight and copy that as a layer but I think your way is much more exact mathematically to starnet. That’s for sharing

@astroedsastrophotographych4562 3 года назад

Thanks Johnny! I like it better than select color as well. I actually think select color isn’t very accurate and more of a guess work. I have an even better technique that is 100% accurate, but have not done a tutorial on it. Perhaps in the future... and that technique is more so for narrowband processing.

It actually turns out that this process of the difference and linear dodge add is incorrect and damages the star data. I plan to release an update in the future. I no longer recommend it. I discovered on my own another method that works seamlessly.

@donsinger1 3 года назад

Another great video. In the next follow-up it would be great if you could clarify what imperfections in the starless image you're looking for that need application of the healing tool. Honestly, on my iPad, the image looked great in the spots you healed :). I am going to use your process on 7 hours of data I have on the Western Veil and follow along as you add more videos. Going to give you a great shout out on Cloudy Nights as you deserve more subscribers.

@astroedsastrophotographych4562 3 года назад

Thanks, Don. In the spots I healed there were left over artifacts from starnet not fully removing star halos. If I were to continue to process without healing those artifacts will show up even more in the final image. If I heal them early on I don’t have that issue! Thanks for spreading the word about my channel! Good luck on your western veil data!

@donsinger1 3 года назад

Thanks for the reply. Will look for those artifacts when I try it out

@EODHammer 2 года назад

So, only stretch your data then do this and then further process the starless image ie, camera raw, dust, and other tweaks? Then after satisfied with starless add the stars back in? Sorry, but I'm not clear on that part. EDIT>>>>I figured it out, I finally found part2 but had a hell of a time finding it lol! Great info, I like your technique.

@@astroedsastrophotographych4562 I used your layer star reduction/control method on this picture: instagram.com/p/CH1FKa3HIVE Worked like a charm. I'm using Affinty Photo and used the "in-painting brush" to fix/heal the halos around the biger stars and their spikes from the newton. Than I used the "add" layer mode. Just like you described. I also uses the starnet image to fine tune the nebula and push the nebula while trying to control the noise and surroundings. Other method where curve stretching, channel stretching to boost the red part of the nebula, nik collecton to denoise. I have to check all the layers I still have in the original file to make a note of all the stuff I did. Otherwise I will forget it until I get a new image to process. ;) Clear skies and stay safe.

@OzarkBill Год назад

Hi and thank you for this and your other great videos that I've recently discovered. You probably answer my question in part 2, but I cannot find that if it exists. Most folks seem to use Starnet prior to their primary stretch. They recommend giving a 25% stretch to allow Starnet to work and then do their primary stretching on the object to protect the stars. Using Shelly's arc hyperbolic sin stretch eliminates this need, I suppose, but I am left wondering what the need is for removing stars now? In my current workflow, it seems I can do the later half of my processing without the need of removing the stars. I guess I may be missing something but I was hoping you or another commenter can fill me in. Thanks

@astroedsastrophotographych4562 Год назад

Ultimately whatever works is fine if it is fine for you. I like to do any stretching without any stars present, thus, the only stretch the stars undergo at all throughout the entire process is just the arc hyperbolic stretch. All background data (nebulae or galactic nebulosity) i like to stretch with no stars present. Personally I’ve achieved my best looking images this way. If you goto my channel, i have a tutorial section that has all parts including how I process narrow band data.

@kowalskik.1333 3 года назад

Great vidoeo BUT can you describe how to do it with narrowband images where you have three different "stars only" layers? I guess this star layers need to be somehow combined together before bringing it back into the (also combined) starless picture(?) How to do that? Thanks!

@astroedsastrophotographych4562 3 года назад

Hi Kowalski, yes I can explain it, but it merits more than an over simplified explanation I could give you in this reply. I have been considering releasing my narrowband technique for awhile. Just haven’t had the time. Perhaps in the not so distant future, subscribe so you don’t miss that release. Thanks, AstroEd.

Im watching the video and I know its been a while since it was posted but you keep mentioning "non-destructive workflow" which i completely agree with but you may want to uncheck the "delete cropped pixels" box on the crop tool, as the crop tool affects all layers so there is no going back once you close the document or run out of history actions

@astroedsastrophotographych4562 2 года назад

Nice tip. However, I’ve never ran into the issue you describe with the way my workflow “flows”. So maybe I don’t have a 100% non destructive workflow but wrt to AP it is as non destructive as I need.

Once you remove the stars from the picture using Starnet, it looks like the nebulosity layer has lost some detail. Any chance you can confirm if that's true or not?

Minimal loss if will result. But if you changed you starnet setting, it could be worse. I have no way how to confirm.

@astroedsastrophotographych4562 3 года назад

If you check out my first tutorial on stretching, I cover how to use the channel mixer to correct for this. In my case it is a green color cast, in your case it is blue. So you would do the operation on the red and green channel in the channel mixer by increasing the red and green blue parts only and watching the histogram until they’re aligned. Hope this helps.
