50 Hours of Data to Hubble Palette: Full PixInsight Processing Workflow shown on my Tadpole Nebula

[@mupangamwanakatwe1300]

Excellent tutorial! 👍🏾👏🏾👏🏾👏🏾👏🏾 Please do keep them coming!

[@mavericknz3317]

That trick of applying SCNR to the inverted RGB image to remove the purple star halos is absolute gold! I hate how those halos look on my refractor images but had never found a way to satisfactory mitigate them until seeing that part of your video - I can't believe how well it works and such a simple process. Thanks for sharing!

[@aaf383]

I've been in this hobby for a few years and you are teaching me useful techniques I didn't know. Thank you, keep doing this, and I'm subscribed!

[@the_space_koala]

Thank you for watching and subscribing!

[@АлексейСоловьев-ц3э]

you are doing the highest quality processing in Pixinsight!!! very good videos! I'm looking forward to new videos, good luck and a clear sky!

[@the_space_koala]

thank you very much. I do try my best :D

[@neXib]

Some very good points on green in the images and also some different tricks than what I have been using so far in PixInsight, very helpful. Please keep making these, something we can come back to and reprocess with to try different things :)

[@declancarey4664]

Great work, superb image and thanks for sharing the techniques. Very interesting to see how you approached the noise reduction! More like this would be most welcome.

[@johndaley9188]

Neverr seen a reverse image mask. Makes sense. You're giving me more and more incentive to expand my post. More to learn. Thank you.

[@the_space_koala]

Yeah I think it’s often useful! Pixinsight gives you the option to use the inverse of the regular mask but that’s mentally harder to adjust with the curves 😁

[@beatsntoons]

that is an absolutely stunning result. Thanks very much for this workflow! Much appreciated

[@the_space_koala]

thank you for saying that

[@64gkb]

Very instructive in many ways. So many insights. Please keep making these!

[@the_space_koala]

thank you and I will

[@JaySala]

I love watching different people using PixInsight. I'm just getting started with it and I'm always learning something new so please keep these videos coming :)

[@the_space_koala]

I am happy to hear that you are finding the videos useful!

[@CosmicCaptures]

Thank you for the excellent tutorial, Luca. You shared a treasure trove of very useful tricks, such as the reverse mask technique for limiting areas of noise reduction. Your meticulous approach to editing in PixInsight is truly inspiring, and I believe I can learn a lot from you. I completely agree with your point about sharing editing workflows; it makes little sense to present a specific recipe since every image and data set is different. Regarding the Hubble palette, I understand its origins, but I have never been particularly fond of its appearance. As you mentioned, there is no right or wrong way to edit narrowband data. Thank you for all the effort you put into your channel!

[@the_space_koala]

you're not the first person that tells me they don't like the Hubble palette - this is also a nice thing because you will process images in a different way and at least our images look different! As we are all constrained to photograph the same sky, different styles bring diversity :) thank you for the kind words. clear skies!

[@CosmicCaptures]

@@the_space_koala You are right, it's a good thing that we don't like all the same things. Diversity is great.

[@robertotolosajr]

There are many different possibilities with Pixinsight. It's really cool to learn new techniques. Your methodology is very good, thank you for sharing it

[@the_space_koala]

thank you so much! I learn something new on every single image I process!

[@FrancoGrimoldi]

it's great to get to see such level of proficiency and knowledge, rendering a stunning image!

[@the_space_koala]

thank you

[@yasef1965]

Thank you so much for showing us step by step your way processing with pixinsight

[@dman9405]

Very nice! I really like these tutorial videos.

[@the_space_koala]

thanks, I'm glad to hear

[@esseremi]

we want hoo next time, nice tutorial

[@the_space_koala]

Thanks! I’ll do it the next time I have a photo in HOO

[@ridetheliger4176]

Very useful, with cool ideas! Thank you!

[@the_space_koala]

Thanks for watching!

THIS WAS FREAKING AMAZING. I have a meade lx65 8 inch and I will be following your approach!!!

[@markw4095]

Definitely appreciate your workflow videos so keep at it :)

[@alexandreastronomy8022]

Excellent, thank you!

[@jurgenlandrie1380]

Awesome video!! I wish somebody explained their workflow In Siril the way you explain everything.

[@the_space_koala]

I wish I was a proficient Siril user!

[@jurgenlandrie1380]

@@the_space_koala Never too late to start 🤩

[@earlteigrob9211]

Excellent tutorial!!! Your final image is amazing!!! I have a couple of esprit scope setups but have yet to shoot anything. (Hopefully soon). I will be following this tutorial when I have some data. I am also interested in the SHO Colorize technique. It seams that it would allow for a lot of creativity in color blending but than I know very little about this topic. Thanks Again👍

[@the_space_koala]

thank you! hoping for you to get your first light soon! There are infinite ways to blend the channels - mine here was a very simplistic, purist approach (which I like) but one can surely get creative! You can also google the "foraxx palette" - there are more combination options that are super easy to implement via pixelmath and they give interesting results

[@earlteigrob9211]

@@the_space_koala Thank you for your reply, Luca. I will do some research on foraxx palette as well.

[@janbielanski5141]

Great work!!! Interesting approach, I've to try it, in my processing way I make color image very early, then I use SPCC for narrow bands, after that BXT and very late NXT.

[@astro7996]

For some reason I always thought that you were Australian (wonder where I got that from?). That target is one of my all time favourites, hopefully I'll have a chance to shoot it this winter. Thanks for sharing this tutorial!

[@arnsteindale5531]

Very nice video, I like the way you did the reverse mask technique for noise reduction. Is it possible for you to share the pixelmath expression you used here?

[@the_space_koala]

thanks, there was no pixelmath involved, cmd+I (or ctrl+I on windows) will reverse any image!

[@Thommy78]

Awesome image. Great work. Are you on astrobin?

[@the_space_koala]

thanks! yes I am - app.astrobin.com/u/the_space_koala

@ you have a follower ;-)

[@tomdaigon8707]

Another well crafted tutorial! Would you consider doing a version for those of use that use a OSC camera? Using PixInsights DBXtract function can extract Ha , O3 and S2 from a full color one so the 2 approaches are somewhat similar in terms of processing mono images. Or whatever workflow you think will elicit similar results from a OSC camera. Thanks!

[@the_space_koala]

that's a great idea! even for that use case there is no one workflow fits all.There are many OSC users with 2 filters (SiiO and HaO) who then get out the true signal for each gas, and there are those with a dualband (HaO) that would like to turn it into a Hubble palette looking image without any actual Sii data, and these 2 use cases are vastly different.

[@silvanodepetris]

grazie per il video davvero chiaro e molto comprensibile, mi piacerebbe molto vedere un flusso di lavoro su un soggetto in lrgb , nebulosa o galassia, sarebbe davvero bello ! trovo molto giusto non rimuovere il verde, fa parte della hubble palette !

[@the_space_koala]

Grazie Silvano, sono contenta che l’abbia trovato comprensibile! Prima o poi farò anche un video in LRGB 😁 manca poco per la stagione delle galassie

[@fotoenvrossi3104]

I don't have pixinsight I use siril (with poor results :P) I'm not a professional in astrophotography I only have a quattro 150p and asi 533mc but I have to say that you are very good at processing images and extracting the best detail. welldone

[@the_space_koala]

Thank you! Everything I showed here could be done in other software including siril with a few third party plugins (have a look at Graxpert denoise, as well as Cosmic Clarity). I am a big pixinsight fan but it is not mandatory to use it to get nice images :)

[@christopherthomas3403]

Deep Space Astro has some good processing videos using Siril. They helped me get up and running with Siril.

[@titanus22222]

Thank you for sharing this video. Did you shoot from a remote observetory or did you this in switserland ?

[@the_space_koala]

I did this from a dark-ish sky site about 45 minutes from my house (bortle 4)

[@johndaley9188]

I'm a S30/S50 user. Before I jump into the "traditional" telescope world, it would help if I understand calibration frames. What are they, why are they needed, how to create them and what to do with them. In the smart scopes world, are they addressed behind the scenes or maybe not used? Thoughts for possible video.

[@the_space_koala]

I did a video on calibration frames in my “Deep Dive” playlist - it doesn’t get any more detailed than that 😁

[@taras3702]

I tried getting an SHO image of the Rossette Nebula once, and found the overwhelming green cast to be problematic with Nebulosity but less so with SIRIL.

[@the_space_koala]

the first time around it is scary but once you get the hang of color calibration it makes these photos super easy

[@titanus22222]

Hai thank you for your answer on my question but i have another question. You used a PixelMath formula to stretch i have tried to copy that but it doesnot work with me. Is this formula special for you or can i use it too Greetings
