[@josephluciani5531]

As a grateful and dedicated follower of this channel, I felt a need to share my appreciation with the community. When I first started watching Lukomatico (I believe Luke had 184 followers) I was close to giving up astrophotography. There was something about Luke’s videos that keep me going. Perhaps it was his easy going love of this hobby or maybe his simple, hands on instructions, whatever it was, Lukomatico has been and continues to be the very best channel on the Internet. That said, watching this video with Bill is one more reason why I know my continued understanding and growth is guaranteed. Digging deeper into Pixinsight happens to be my current ambition and Luke’s videos (including this one on star reduction), especially his OSC Hubble Palette videos have been simply brilliant. As anyone who has been following Luke will attest, he’s not only dedicated to ‘us,’ but to working tirelessly to provide top notch instruction and perhaps more importantly, ongoing encouragement to us fledgling students of astronomy.

[@lukomatico]

Aw mate, that was really humbling to read - thank you so much Joe, I'm very happy indeed to know you've found so much use from the videos my friend 🙏 Clear skies!!

[@LogansAstro]

Wow, Bill, this is fantastic. Thank you so much for sharing these tools with us. Although we spend a lot of time minimizing stars in our images to highlight nebulosity, I personally think the appearance of the stars can make of break an image and having good, natural looking stars is very important. Getting the stars right has always been the area I struggle the most with when processing and these tools will make life so much easier. I am especially excited to hear about your upcoming method to add RGB stars to narrowband. And thanks for Bill's tools Luke.

Huge thanks to Bill for these wonderful new tools. I gave up on using PI for star reduction years ago. MT seemed complex to use but, worse yet, very prone to artifacting with anything other than a very modest degree of reduction. I've been using Russell Croman's Starshrink with considerable success since giving up on MT but these tools are even better.

That was great! Thanks both for taking the time. Soo Bill's effectively making a star layer, doing some clever pixel math so the values are not effected, then reducing by de stretching before adding back in.

Excellent video! I tried all three methods on a ASI533mc image of M78. Method 1 reduced the stars the most, but had a bit of a bullet-hole look. Method 2 was better in that regard. Method 3 had the least impact on very faint stars, and although the reduction in size was the least of the three methods, it looked more natural to my eye.

Thanks so much to Bill for the development and Luke for arranging it..gentlemen and scholars both. A point on using Starnet Luke, using the newtonian I find that Starnet is pretty poor in removing the diffraction spikes on the larger stars. In your experience do you find Starexterminator does a better job?. Thanks again.

[@lukomatico]

Hey there Pete! - I'd say if you haven't already tried StarNet2 then give that a go first as you've nothing to lose by upgrading really - well worth a check! - Failing that though, then StarXTerminator in my experience tends to deliver more robust results on average anyway with all types of scope I've tried, it is worth the cost if you do a lot of image processing! :-) Thank you very much for your kind words and support Pete, it's really appreciate mate!

​@@anotherastrochannel2173 lol, well done Bill. I tried to click the 'Alert Bell' on your channel, but it doesn't work because the "For Kids' option is selected. Wasn't sure if you know this, but you never want to select 'For Kids'. It puts your channel in safe mode and restricts it too heavily.

Nice one...got a free trial of PI and tbh I was feeling the star reduction available was no better than the free starnet subtraction method I've been using for a while...but this looks like a winner.

Oh ok.... that is really great!!!

Glad you like it my friend!! :-) Clear skies!

How good is this!!, I use GHS for final stretch and both starnet2 and starX struggle, hoping this will work.

Is there a video for how to use Bill's new tools for OSC to Hubble SHO like the one you made using the HOO palette? Thanks.

Hey Gary! - Sorry about the late reply, I got back to your email before this haha!

[@mikepaling4736]

Hi Luke ... this is REALLY impressive and I would very much like to try out Bill's new tools. However I am having trouble downloading the tools from your remote drive ... I just get the text files. Are you able to to tell me how to download them like you show in the video? Cheers Mike

[@lukomatico]

Hey Mike! Sorry about the trouble mate, some people have reported this issue. You should still be able to download it by clicking the save button in the top right corner of the window that pops up with the text in it. Alternatively, you could download this tool, along with a few others all packaged together from any of my recent pixinsight tutorial series 👍 hope that helps.

[@stuartburman177]

After you do the star reduction method, can you further process? Or should this be the last step before calling it done? Thank you! Great video.

[@lukomatico]

Generally speaking mate it should be the last step before saving it out aye, you could maybe do tiny touch-ups without much damage but I'd avoid serious processing 👍

[@galbanese7329]

Thank you gentleman for all your efforts. This video was great [like they all are], Bill, thank you for sharing the tools and the great explanation of how they work.

Hi Luke, another great video, and also thanks to Bill… Can I ask Luke, I am new to pixinsight, and downloaded the files in your Google drive, I got the star reduction files, but also got a load of others, one lot with colour masks, and another with Base, and colour masks again, so what is the “base” and how come I got the colours masks twice..?? Mad a bit confused… Cheers Luke..

[@lukomatico]

Hey Stewart! sorry for the confusion there mate, the only file you needed to download was Bill's star reduction :-) it sounds like you downloaded them all instead! I host a few different things on there to help people out, hope that explains it mate!

[@Astro_Shed]

@@lukomatico ok, but is it worth me keeping the other things, would they be useful, the colour masks look good as I saw that video you made too, and are the base icons, just the same as the ones already in PI, are they just some basic ones to get going with some simple processing…?

[@lukomatico]

@@Astro_Shed In my opinion it's worth keeping them yeah mate, if you want to do that then it'd be best if you combine them all into one saved set of process icons though, thats how I currently have my own setup 👍👍 hope that helps mate!

[@jesuspineiro1622]

Hi Luke and Bill. The video looks wonderful. Excellent explanation of the mathematical methods for star reduction, they are fully understood. Unfortunately, many of us use Photoshop and the method would apply differently. Would it be possible for you to make a video to apply these star reduction methods for Photoshop? I suspect that they should be done by applying math to star layers with high-pass filters or the like. PhotoShop users would be grateful. A big hug to both of you and thanks for transmitting your knowledge to the community.

[@billblanshan3021]

I think I could get the transfer method to work in PS or Affinity Photo using blending math and curves but it would be a time consuming process to do, however if this is something you would like to see, I could try.

[@howardtrottier5470]

These algorithms for star reduction are breakthroughs! Version 1 in particular is very intuitive -- simple and elegant, one of those ideas that makes you think: why didn't I think of it?! Bill mentioned he has a really cool PixelMath algorithm for substituting RGB stars into a narrowband image, which he is planning to share. Can't wait to see that!!!

[@lukomatico]

Thank you so much Howard, I'm very glad to hear you like the tools! :-) Hopefully Bill will be ready to release his new tools soon! - Clear skies!

[@franlober]

Very impressed with the work to reduce stars. In Spain, Pixinsight with VAT costs more than €300 and not all of us who are starting out can buy this software because we first need to buy a guide tube, a camera, a flattener, etc. Since Siril also has PixelMath, would it be possible to apply this in Siril as well, would it be possible or is it too complicated? I would ask you to consider porting these routines to Siril. Thank.

[@lukomatico]

Hey mate! I'm afraid to say I've got no idea if porting to Siril is possible, sorry I couldn't give a more useful answer 🙏 Thanks for watching!

Hi Luke, what's the spec of your pc? I see you are wearing a scan cap. Looking to setup a pc for PI not sure what's best. 🤔 thanks.

[@lukomatico]

Hey there Martin! - my pc is a couple years old now, but it's specs very roughly are these: Ryzen 5 3600x 24gb ddr4 ram Nvidia RTX 2060 If I was building a pc again these days for PixInsight & video editing etc I'd be wanting 32gb ram, faster GPU for gpu accelerated processing tasks (Starnet for example) and a beefier CPU, maybe a 12 core 24 threads offering 👍 Hope that helps!

[@MartinLeeney]

Hi Luke, thank you I'll let you know what I get. Thanks again

[@sidfrede7324]

I lost something in the flow. I use StarX to extract stars after I first stretch an image. I process image without stars working on nebulosity, background, noise, color, saturation, etc. and recombine stars via Pixel math when image complete. (I may also process stars adjusting color, saturation,etc. before recombine). I then use EzStar Reduction. Do I then use this process to do star reduction at this point after I have a nearly completed image after recombining extracted stars?

[@billblanshan3021]

Yes, just use this tool for star reduction only. It's fairly a fast process to do. You can save that as step as your last operation if you want. You can even automate the workflow in a simple process container

[@lukomatico]

Hey Sid! :-) You've got it my friend, you would get great results using these tools right after recombination of your image, I would personally simply replace EzStarReduction in your workflow with these tools and with only very minor time spent dialling in the strength/choosing which method looks best in you should have a superb outcome in very little time 🙏hope that helps! Also as Bill suggests, another good time is as one of your last processes overall 👍👍

[@sidfrede7324]

Thanks! I just downloaded and am anxious to experiment.

[@seemantadutta]

The main image of the tulip nebula where star reduction is applied is a narrowband image, right? Are those stars narrowband to begin with?

[@Steve_The_Ignorant_Astronomer]

Hey Luke Steve here ,,, Question , I took a bunch of images of LEO 1 a cousin asked me if I can get that galaxy .. The bright star Regulus is there and it is so bright. How do I take care of that star and keep the rest ??

[@lukomatico]

Hey mate! sorry about the late reply, that's potentially a tough one! - you could perhaps clone-stamp it out with care but it'll be a scientifically inaccurate image then of course, but it all depends on end goal! :-) another option may be a range mask on the problem star, and targeted de-stretching to kill it a bit! Good luck!
