New Substitute Script in PixInsight!

[@frankenstein77777]

Come on Adam, I can't keep up! I literally just watched your Fundamentals video today on the Substitute with Preview script, and now this one comes out!😊

[@ganymede235]

Excellent utility, great explanation. Makes creating an annual "posterboard" of one's best astro-images easy-peezy!

[@jontalbot9884]

Thanks for pointing out this script Adam. Missed it totally....

[@volens31]

Adam, thankyou. I have an immediate use for this script. I have an image which has one central star as it's main subject and this star core is blown out. I have reshot some 30s subs for tthat star core and can now simply use this script for that one star. Great!

[@ChucksAstrophotography]

Wow, I can see a lot of possibilities with this tool. Thanks for bringing it to our attention.

[@AdamBlock]

Thanks for looking. Please suggest to your viewer to check out my videos. :)

[@roymedina638]

Great presentation Adam! Can’t wait to try this.

[@AdamBlock]

Thanks for watching.

[@ergio1]

Very nice Adam, as always thank you for sharing

[@AdamBlock]

Thanks!

[@davidleejenkins]

Thank you Adam - I find videos like these very helpful! I am also a subscriber to your site. It appears that the new Substitute script updates the Target view instead of creating an entirely new view, thereby preserving history. I was using your Pixel Math solution, but now I no longer need to. I’ve learned, and keep learning, so much from you. Thanks again!

[@AdamBlock]

Yes, exactly. Christoph made this script based on my methods... making things easier!

[@melvinatkins3443]

As always a fantastic explanation with your easy way of getting things over. I real enjoy all of yout tutorials. Thanks

[@AdamBlock]

Thanks Mel!

[@rickbohart6788]

Another great video on what looks like a very useful tool. Thanks Adam.

[@AdamBlock]

Glad you enjoyed checking it out.

[@starsips]

Great script! Thank you for running us through it

[@AdamBlock]

Thank you!

[@SkyShedPODTeam]

Cool Adam! Thx! Yes, make more PI videos please. ;) CS!

[@NeilCorke]

Thanks Adam. Keep up the good work!

[@AdamBlock]

Thanks Neil!

[@stephen2615]

Nice stuff. If only I understood more about PI!!

[@AdamBlock]

Well... since you watched this... you DO understand at least a little more about PI. I even showed you how to make an image... change its color...etc etc. Add up all these little things..and eventually you will know *all* things.

[@jeffdutton1910]

that's awesome...I've been using the manual method with HDRMT to improve galaxies and globular clusters in some of my old datasets.

[@AdamBlock]

Right? This particular usage can save a little time.

[@Spaced_Out_Bill]

This looks pretty cool, I'm installing. Is there no need for feathering the edges?

[@pompeymonkey3271]

I think that running the masked HDRMT on the preview is to create the correct brightness gradient between the source and target of the images. I think. lol

[@AdamBlock]

Depends on what you are doing. Somethings you will ...other things you will not.

[@grigoryvidishev1810]

Thank you Adam, it is a useful tool. How do you deal with borders, you can get borders visible when you insert into another image. I guess you need a gradient mask to avoid the transition border.

[@AdamBlock]

Yes... if your application of substitution pixes has differences between source and target..a mask will be necessary. Not all uses of substitution will need a mask..

[@steveweintraub1113]

Great tutorial, thank you for walking us through this one!

[@filipgloria]

Very nice video! You could use it with the star alignment tool to get the solitary preview in the exact coordinates again (as long as there are enough stars in the preview).

[@M31glow]

More, please!

[@eurismac]

@adamblock Adam if we apply a mask, we should see only the masked pixel changing, am I wrong? Cause I still see all the preview window area being transferred over the target image

[@AdamBlock]

I just checked it out to be certain. Yes, a mask on the TARGET image is honored. You will see the gray/white pixels of the mask change...yes. Black masked areas will be protected. Be certain you have this part correct.

[@avt_astro206]

Amazing Tutorial, sick Image! 👏😮

[@AdamBlock]

LOL..thanks!

[@johnadastra1754]

Usually we use a Preview to test our settings, then when satisfied, drag the arrow to the original image to do the whole thing. Are we saying Substitute then only does a portion of the original? Control the Preview edges with a gradient mask?

[@AdamBlock]

Yeah..that is one (perhaps typical) usage.

[@annihilator1983]

Hi Adam, really cool stuff, I m wondering whether I could implement this in somethign I ve been thinking about, I d like to substitute a region of a wide angle picture with a close up made from a larger focal length telescope, I realize this causes a mismatch in pixel size, and thats where my brain hurts and says its not possible, but instead of making a mosaic of many pictures done by a larger focal length, I could selectively have more detail in regions of a wide angle picture and therefore save time by not taking pictures of all the in between (less interesting) space. Do you have any guide you could direct me to?

[@ferashaki7528]

Thanks! That is a very interesting tool indeed! So basically, it is possible to use the script from any script's preview to a target image, right?

[@AdamBlock]

Yes, basically any source image to any target image.

[@slmdaddy1]

Thanks @adamblock your videos are helpful, I am also subscriber on your website.

[@AdamBlock]

Thanks.

[@jasondain8713]

It looks neat and I definitely see some possibilities but I think I like my current workflow better. I prefer to clone the image and use a mask to control where I apply HDRMT and then blend the result back to the master. I feel like I have more control that way. I think this might save a few clicks but I prefer the control pixel math gives. Thanks for sharing.

[@DSOImager]

That's a pretty slick script :)

[@AdamBlock]

Glad you like it.

[@CookedLight]

Lightroom does that non-destructive, is this script the same? can these masks be feathered like LR does?

[@astrophoto_andy3335]

I'm wondering if this is something you could use for smoothing out a background... say slightly noisy RGB with a Ha background. The script really makes you stop and think about the possibilities.

[@AdamBlock]

Yeah.. it is a nice utility to know about ...it might come in handy.

[@michaellewis5921]

At what point is the script available and from where?

[@danjensen9425]

Awesome

[@AdamBlock]

great!

[@tomdaigon8707]

Way cool!

[@Thunder_Dome45]

I can possibly see good things for planetary and solar ha images, unless I'm missing something. Maybe processing moons of Jupiter and putting them with Jupiter, or doing proms and surface of the sun for ha. Also I never thought about using HDR on just a preview. I usually just run it on the whole image of galaxies.

[@AdamBlock]

This is one of the "Adam Block" secrets I let out there...lots more good stuff like that to be found on my site. :)

[@rickbria8420]

Great video. One usage that pops to mind is combining high resolution galaxy images, such as M81 and M82, into a wide angle image of those galaxies?

[@AdamBlock]

@@rickbria8420 Sure... probably still need a mask. Interestingly one of the easy uses... sometimes people want their signature placed on their images... this is an easy way to do it. :)

[@BrentMantooth]

sorry to ask for support on youtube for someone else's script (I am a registered fundamentals user). I just downloaded this from the repository and got the following error when I went to use it: Error: Parsing code signature file: Parsing Signature element (line=8 offset=3): Missing code checksum data: C:/Program Files/PixInsight/src/scripts/ChristophOehler/Substitute.xsgn that element in the .xsgn file is the developerID - (which matches the repository server name) where would one start to figure this out? or contact the author (no contact info in the comments of the code)?

[@AdamBlock]

I have only seen this error with older versions of Pixinsight (because the PI developers changed the signature thing for scripts in the latest version). I would post on the official forum if you are using the most recent version of PixInsight.

[@alexworonow788]

I got the same error. Simple fix: delete the signature file

[@BrentMantooth]

Turns out I missed there was a version update for PI. That fixed it for me

[@alexworonow788]

I have set PI the repository to automatically update. Installed just a couple of hours ago, and got the one that has the error. Is there a web site to get the most recent version?

[@BrentMantooth]

I just went to the download web page for PI to get it. There was no internal lookup that indicated there was an update
