Guys this is amazing! I am humbled by the response, I have already received over TWENTY fully processed images, with people putting so much effort into the processing, and explaining the processing. It's honestly incredible and humbling, and far more of a response than I expected! I am planning on doing a follow-up video to feature the wide number of interpretations of the same source data! Thank you SO MUCH everyone! And next time I do this, I think I'll have to create an official communication channel for it...

[@astrofromhome]

Hi Cuiv, unfortunately I did not have any time earlier so I am starting the challenge just now. I had to finish my own data of the Rosette Nebula first. It just took me 3 weeks to get the the result that I have been expecting. 😁

[@gregorybchapman]

Cuiv, first, let me just say that your videos have been the best guidance I've had to follow for all those things about astrophotography that interest me...including taking the most appropriate level of laziness wherever possible. Second, this is beautiful data and someday, perhaps, I'll be able to pull together such high quality results myself. In the meantime, playing with yours is just fine practice. I started on your data with SPCC because I really want to protect those star colors so that they don't distract. A default run with ABE and then SCNR were applied to try to deal with that nasty gradient in the lower right corner next. I also used the entire *XTerminator suite (at the appropriate times in the process). EZ-Soft Stretch was followed by Histogram to try to set the black point. Next, I did re-apply stars using BillsStarReductionv1 with default settings. Finally, I used Bill's HOONormalizationv4. It's at that point that I left campus and wondered if you had spent any time using Scripts/Utilities/Color Mask. By creating those simple color masks with a touch of blurring, you can do a number of things with Curves to specific color masks as they are applied to your work in progress. Working with Cyan and Green masks in the CIE a and b of Curves, I could make a lot of changes to the core of your Rosette, including controlling its brightness and saturation. A bit of dynamic crop to trim the remainder of the gradient from the bottom was the last step. Now, I don't know why, as a Lazy Geek, you can't be satisfied with your own work beyond being your own toughest critic. Perhaps you're too critical of yourself. In my own case, I KNOW I tend to overwork images until I'm the only viewer satisfied with the result.

[@DeepSpaceAstro]

Wow that's some great data. The detail is amazing. I'm taking a crack at it and will send it over soon. Thankss Cuiv~

[@othonbenavente1876]

Cuiv, Stop it. you're killing me. This is a beautiful image. Colors are not ever 'right or wrong'. What I enjoy the most after going through the processing is getting lost in the visual texture of the images. What you achieved is a feast for the eyes. That said, I will see what I can achieve on my own as a practice exercise, given that we have another week of rain here in the San Francisco Bay Area, but I love what you achieved already. I don't follow most of your videos because I don't use Nina or PixInSight; I do however, appreciate your energy. I love this image.

[@WhooptieDo]

Hey Cuiv, great way to interact with your audience! Someone shared your video and data in Rory's discord, so I spent about 30 minutes playing with it. I ended up processing only the narrowband data... I couldn't justify playing with dual NB/OSC data when narrowband was presented. I actually enjoyed processing this data, and I think I got a pretty reasonable result with it. As for your blues, I think I may have achieved what you wanted,, and here's my trick: Remove the stars, Autostretch the channels, drop autostretch to histogram and convert to non-linear. I know most people will say this is heresy, but it works well for me. You will end up bringing alot of background with you, but this is fine. Make sure you've done a proper denoise prior. Once the channel is non-linear, do a basic arc-sinh type stretch in curves. The goal is to drop that background down while keeping the entire data spectrum. This works particularly well with Oiii. You will end up with a less stretched, more translucent blue channel that doesn't overpower the image. I've posted my image in the Astrobiscuit discord under #share-your-data. Should be easy to find, many folks have already ponged you. lol

Hey Cuiv, your image is actually pretty good! I've just spent around 8 hours playing with the data and I'm still not happy with it. The data is excellent though. BlurXTerminator works very well on this image, the improvement in the 'animal parade' detail is absolutely insane. Will have another go tomorrow!

[@CuivTheLazyGeek]

Thanks for looking into it Pete!

[@demetriosmarolias126]

Just had a go with your data. I found instead of aiming for the blue use the hue to get it to magenta first then invert- SNR green and the blue appears then mask the blue and BOOM your there 😎I just did the same steps as you to get the rest of the image nice but used the curves and the Hue to bring out the magenta where the blue is. it’s a lot more easy to bring out than blue.Then SNR. Hope this helps

Cuiv, I remember sharing my Jellyfish Nebula data probably 4 or so years ago with you on CN. I got ya fam, I'll process the data tomorrow and share with you.

[@ysl109812]

That sounds fun. I am in! Edit: I just played with the file for a couple of hours and now realized how challenging it is. I have a very similar workflow as yours utilizing BXT and Bill's PIxelMath scripts. The data is beautiful and all is fine and smooth until applying Bill's HOO normalization scripts. I suspect Bill's HOO Normalization does not favor this particular image and I will perhaps try a more traditional approach.

[@CuivTheLazyGeek]

Exactly the problem!! I'm going through the comments to see if someone found something good!

[@Mike_Gibbs971]

Hey Cuiv. I'm no pro at this, and actually, I look to YOUR videos for help! I did take a go at your quite nice data, and I have an image I've processed in PixInsight. Not quite sure how to get that to you! Anyway, was great to process some of your data - Thanks!!

[@DSOImager]

I took a quick look at the data but did not do a full process yet. In regards to the blue.. one of your control levers is green. If you want more of a teal look, you can actually try increasing green a tiny bit via curves. The CIE a* component curve might be a good option here.. just pull towards green ever so slightly. If the color is too "pastel".. with a color+range mask you can pull back on the rgb/k. I actually have a video on my channel that covers working/managing colors that you might find interesting. Green really is a good control lever.. one of the reasons why I advocate against using scnr to blow away all the green. Side note.. I bet one of those s2/O3 dual band filters would be awesome with this setup. You'd be able to isolate real S2 data and then do legit SHO. Would be cool to see how that works with your hyperstar setup (assuming the filter works well enough at f2!).

[@CuivTheLazyGeek]

Thank you so much for the tips! Do you have a link to one of those S2/O3 filters? That sounds quite interesting! I subscribed to your channel and will check it out :)

[@phmasampaio]

Hey Cuiv! First, I love your videos! Second - don't feel bad about the Rosette... Of all the DSOs I've imaged, it is by far the most difficult to process. I've done multiple iterations on the same data, and only after like in the 10th time I did achieve something that resembles something I kinda like. The core is extremely hard to balance in NB, and even in my dualNB image I could't achieve that deep blue we see in other NB images. After working with the Orion Nebula, I came with an idea which MAY work - did you try using HDR Multiscale in PI? It may help to balance the brightness of the core with the faint nebulosity.

[@Hebert6615]

Thanks so much for this - I do tend to be hard on myself... I even posted the picture on Instagram and then removed it because I didn't like it... Sigh...

[@deep_space_dave]

Hey Cuiv, have you ever used the Normalized Scale Gradient script to normalize your data instead of using the localized normalization of WBPP? Since you image in a light polluted area, this would help remove or at least make it easier to remove light pollution gradients. Living south of Chicago, the light from the city always creates a gradient and this script almost completely removes it from my images.

[@Astroephotography]

Hey Cuiv, your image is just stunning! I’d dream to be able to obtain a final image like this. I’d have a go myself but I wouldn’t be able to beat what you have done there. Top image!! 👌🏻

[@CuivTheLazyGeek]

Thanks Philip!!

[@deep_space_dave]

Very clean data! Looks a lot like mine except 30hrs LOL. I normally don't do anything fancy as I am a purist and minimalist so usually I would just DBE (but this data looks like it doesn't need it), Spectrophotometric Color Calibration, BlurXterminator to tighten the stars, adjust the curves a little to bring out the nebulosity and darken the background, and add a little saturation to make the color pop a little more, do a GHS then finally a NoiseXterminator to clean it up a little more. I am not a fan of false color but thats just me. Clear Skies! Eventually 😕

[@CuivTheLazyGeek]

Thanks Dave! I completely understand on false color - the rosette though... it always feels to me that there are so many good ways it can be presented. Clear skies, I hope you do get some soon!

How surprising, yesterday, on January 2, I also shot Rozetka in Odessa, with my new Tauptek 571 C camera, though I don’t need help, I managed to shoot only 21 shots of 5 minutes each with an L-Extreme filter and Rozetka went behind the house.

Salut Yannick. Joli chalenge que ce traitement...Je n'ai travaillé que sur le fichier couleur l-extreme (comme chez moi à Lyon). Pour commencer, je fais toujours un star alignement sur les 3 couches (je le fais systématiquement en sortie d'empilement) puis un gros travail avec DBE (pas facile avec ton coin en bas à droite...). J'ai de nouveau extrait les 3 couleurs pour faire une couche Ha (à partir du rouge) et un Oiii = 2/3 G + 1/3 B - 8% de R (en effet, si tu croises la courbe du L-Extreme avec celle du IMX 571, tu vois que l'Oiii est polué par des résidus de rouge). A ce titre, es tu passé par un Bayer Drizzle pour sortir ton image, car l'algo de débayerisation classique polue les couleurs avec les pixels voisins alors que le bayer drizzle scale = 1 Drop shrink = 1 non). Sur le RVB, SPCC pour les couleurs avec les filtres l-extreme, puis BlurX et NoiseX. Montée d'histogramme avec eZ soft strech. Extraction de la luminance du RVB. Extraction des étoiles avec StarX (étoiles que je garde pour plus tard, le starless, poubelle!) Avec le Ha et Oiii crées plus haut, BlurX et NoiseX. Linéar Fit entre les deux puis montées d'histogramme avec eZ softstrech.

Réintégration des étoiles et voilà le RVB pret. Travail sur la luminance avec Hyperbolic strech (c'est plus continu que curves je trouve), un coup de DarkStructureEnhance et voilà, luminance finie. Combinaison RVB+Lum. Quelques petits ajustement dans DarkTable (dont suppression de la brume mais en protégeant les étoiles) et voilà la finale, pas trop de bleu et recherche de la profondeur dans le coeur drive.google.com/file/d/1n1N9PPC3v9mYv7TBvVpdS5UMLkJAtLkq/view?usp=share_link

The XISF does have the astrometric solution - weird if it doesn't... you should be able to solve with 300mm / 3.76um pixels... If you use BXT, apply it after SPCC!! And you may need to mirror the image for it to work :)

Hi, love your 30 hours of data. With your light pollution you may want something like the L-Ultimate. There was serious background light pollution in your image. I use GraXpert to get rid of it. It is a free tool and the best too for background extraction that I have seen. Then I ran BXT, NoiseXT, then stretched the image, I ran HDR on it because the core was too bright. Then I brought up the histogram and lower the brightness of the core some more. Then I could run Bill Blanshan's script without blowing out the core some more. Then had to tweak the colors. Did some of that in Photoshop. It came out pretty good

[@chriscaprette2361]

Could you use Bill Blanshan's color masks to get that turquoise color? Specifically, use the blue mask (and possibly use the GAME script or range selection to modify the blue mask) to select the region that is too blue. Then apply the mask and then use curves to increase the green in that region.

[@CuivTheLazyGeek]

Yep, I'm trying that - it does help, thanks for the tip!

[@Kata_Mae]

Instead of calibrating colors, I always try to calibrate the brightness of the background in each layer first, manually and while trying to keep the stars and nebula level mostly unchanged. Anoying, and I always fail :p But you already have a much better result than anything I can get so you really only need to change the blue to turquoise. mmm, The composition of Siril allows to select the color used while doing it, you can make a Red-Green-Turquoise composition... maybe try that with the 3 layers of your FINAL image ?

Aaaaah going back to Siril may be necessary. So many tools to learn and play with! Thanks for the tip!

@@CuivTheLazyGeek I know there is a way with photoshop to shift a specific color, coupled with a mask it could work too I think, it would be very "manual" though. THinking of it, it might even be required to work on the pixel colors rather than the RGB layers.

OK, astro photography is not my thing unless you count the Moon... :^) But, for your little problem with the blue core I have an idea. I don't use Photoshop - preferring Capture One and Affinity (real noob with Affinity); but with Capture One in the Adjustments tab there is the Color Editor where you have eight main colors to pick from. Once selected (red, orange, yellow, green, teal, blue, purple and a kinda pink) you can adjust the Hue, Saturation and the Lightness. Photoshop must have something similar. Now I'm used to processing "normal" cameras, perhaps with your narrow band data you won't have the lattitude in the data to adjust but hey. Tossing you a straw. :D

[@Paul-jb6rk]

I concur that Capture One offers the best color editing tools for post processing for photographers. But I think he’s trying to get the result without adding any additional post processing tools to his workflow. I would suggest capture one only if there is no other way. But I doubt that, it should be possible, though I’ve never used any of the software he’s talking about.

However; all of them offer free trials so it can be a cheap experiment to see if it's worth the bother to add more tools to your kit (and learning curve to boot!).

[@ubit64]

Are you really stacking to 16 Bit images? Or is the supplied data a converted version to save download time and space on the drive? If you stack with 16 Bit results you maybe loose data as stacking in fact increases the bit depth if done with a stacker that internally uses a higher bit depth. Simple example: If you look at a single pixel and only 2 images the (additive) stacking creates the result as the sum of 2 pixels (normally scaled down by a factor 2 = number of images). If the ADU is around 10-11, you maybe see 10 ADU in the first image and 10 ADU in the second image resulting in 10 ADU stacked. But maybe the first image has 10 ADU, the second image 11 ADU => 10,5 ADU. Both images 11 ADU => Result 11 ADU. You see that there is an increase in the resultion as the stacked images has values between the values of the single frames. Doubling the number of exposures during stacking adds another bit to the result. 2 Images => 1 bit more, 4 Images => 2 bits more, 8 Images => 3 bits more and so on. If you stack with the same bit depth the original frames have (or save the resulting image with the same bit depth) you actually loose information that you have captured. Depending on your monitor and workflow (10 bit? 12 bit? HDR? How much stretching is needed?) this can lead to visible steps in fine gradients which are often present in nebulas.

[@CuivTheLazyGeek]

Thanks for checking! I used PixInsight fully, including for stacking (based on the initial raw images from camera), so it should all be from16 bits, and processed with 32 bits depth in PI...

Hello @CuivTheLazyGeek, have you try HDRMultiscaleTransform ? I get rather satisfactory results on the heart, much less burned! (With a mask create with Script / Utilities / Game)

drive.google.com/drive/folders/1KyoyZh5dvGX9BZNIHcHXV0mieGzA09Cv?usp=sharing Here are the different edits that I did. Thank you so much for this opportunity. It has been so cloudy in Indiana for the last 3 months I was starting to lose hope in the hobby. the stars themselves still need a little work but my workflow was to align and combine the data in astropixel processor as I stated before then cropped and removed the light pollution Saved as 32bit tiffs. I then opened the images in photoshop and did a level adjustment pushing the mid slider to the left. I then sis a second level adjustment pulling the left slider to the edge of the histogram. next I converted to 16bit removed the stars with starnet++ using apply image, I created a star only image I then worked both the starless and star only doing several curve stretches and a hue and saturation adjustment then on the nebula image I removed light pollution again, ran gradient exterminator and Hasta la vista green and then ran several adjustments with Camera raw filter until the image looked as I wanted. Next I overlayed the star layer using linear dodge (add). Lastly with the HOO image I adjusted the nebula layer around the stars to remove the distortion. I would need to do that with each of the other images as starnet++ leaves a lot of stray pixels that need blending but there are thousands of stars to still correct and I have to stop for now.

Hey Cuiv Did you ever try the "Foraxx palette", the dynamic NB palette (HOO or SHO) introduced by @thecoldestnights and explained by great videos of Paulyman Astro (he has a great osc dual nb process on IC1396), the foraxx look is way more pleasing, dynamic, dramatic (in my opinion) as the standard hubble palette...☺️

[@CuivTheLazyGeek]

Thanks for the tip! Yes, I think I was one of the first to reference Foraxx's Palette on KZbin back in June 2020 :)

@@CuivTheLazyGeek Aah, really, was not aware of that but will have a look at your reference for sure.🙏

[@jeffallisonastronomy]

Hi Cuiv, awesome pic. I posted a small vid processing it in Pixinsight with the blue more of a turquoise here kzbin.info/www/bejne/apmlo55vdsusgZY Maybe this process is something you can use.

[@andywray3446]

I'm very new to narrowband processing, but had a go at quite a different colour pallette as you can see at: drive.google.com/drive/folders/1OWfucrXJ5hmmUHgKVyVpkEWVPTg-l4bq I used your narrowband SHO files and did a 50/50 mix of SHO and Foraxx colour pallettes plus some tweaks. It's probably over-processed and over-saturated, but should give you the gist.

[@CuivTheLazyGeek]

This is super cool, a really neat mix of colors. I do get the gist! Thank you!

Hi Cuiv. Fantastic data on the RN. I've used PixInsight to process the NarrowBand data. I sent it to your gmail address via WeTransfer. I hope you like the result.

That is really nice, I love this approach. It manages to get both the nebula AND the extended nebulosity out super well. I need to get back to Siril!! Thank you!

[@andrewbickley5271]

@@CuivTheLazyGeek Steps taken in siril 1.1. Open stacked OSC file. Split channles RGB. Open R file use background extraction use settings -rbf -samples=10 -tolerance=0.1 -smooth=0.5 (remove points on nebulosity add darkfield points missed do to excessive gradient), check dither , apply, save file, repeat on G image. (doing both images separately removes more light pollution from the G channel showing extra fine R nebula in final image) RGB composition RGG ( too much noise in the B channel) Star processing , check simple stretch and starmask , run, go get cup of tea. Open Starless file , Histogram transform , auto stretch , hit apply, in same window shift individual channels to align peaks. Asinh transform , stretch factor 3.0 , blackpoint 0.2. Generalized hyperbolic transform , change mode to inverse hyper, select only the red channel, increase stretch factor until core is the color you wish , then increase symmetry point to bring back background nebula. save file. open starmask file stretch stars to desired level save file but leave open. console command iadd starlessimagefilename tweak to preference. general note about sliders in Siril , quite often a value of 2.9 maybe be horrible , 3.1 worse, but 3.0 perfect so can sometimes be tedious finding the exact value.

Hi Cuiv. I took a leaf out of the Lazy of Lazy Geek and processed the data the same way as you then used Lukomatico's colour masks for adjusting the blue and yellow on the starless image then used Bill's Star reduction.

Hey Cuiv, the data looks amazing, you've made up my mind about getting a Hyperstar. Anyways, I gave the data a quick go, i combined the SHO data . I used blurX then Bills stretching math Linked stretch, removed the stars with starX, then used bills SHO optimization, Played a bit with curves and then separated the 4 channels, boosted the L and the R, ran BlurX again on the R, then recombined them, and slightly played with green level and saturation. Gave it a quick noiseX then combined the stars back, Version 1 using pixel math, version 2 using bills RGB stars to NB. "drive.google.com/drive/folders/1woU5tQzwvoz_Y-NbxBCDrRu0VqenpcEw?usp=share_link Something when wrong with the star mask though, had too many windows open i think i used the wrong one. Anyways, I'm sure you will do a way better job I'm still a noob. Thanks for sharing the data.

Hi Cuiv. I took a go at this with the time I had and came up with this: drive.google.com/file/d/1ChJERb2yl1piGYNM1_GZLVqmEBbsNO2V/view?usp=sharing. I tried to replicate what you did but had better results using GraXpert before opening in PI. I stretched with GeneralizedHyperbolicStretch and the colours were at a better starting point. For the colour palette I used the hue curve, first warming the image by boosting the red end of the curve, keeping everything else locked then locked all but the blue/green section of the curve and played with that (using a mask to hide all but the core). I also used LocalHistogramEqualization at several kernel radii. That's not all I used but those are the main things. Not entirely happy with it but are we ever?

[@CuivTheLazyGeek]

Thanks Gary! I requested access to the file!

[@jonmeddings4020]

Cuiv, thanks for all you do to help us in this (very) crazy hobby! I took your 3 monochrome masters, ran ABE, BlurX, NoiseX, then weighted Ha and OIII to SII with LinearFit and combined them. StarX to remove stars, blended Ha as a luminance channel, stretched with GHS and then brought into PS for a final color and luminance tweek.

drive.google.com/file/d/1wHArF_H-pLcDidf9RvOiBwUHwLE8rJd8/view?usp=share_link Quick and dirty edit with Siril and Photoshop without any regards to stars etc. Had to crop the image quite hard due to the O3 stack (which was very strong by the way). The only steps I made in Siril were - Background extraction for each channel separately. - RGB Compositing with Ha as lum - Crop - Invert, remove green noise, invert - Save as tif - Some curves done in Photoshop Keep up the good work!

[@CuivTheLazyGeek]

Wow that is a really nice color palette. I LOVE seeing such different renditions, and it really brings me to how powerful PS can be....!

[@digitalphotons8446]

@@CuivTheLazyGeek Thanks Cuiv! I forgot to mention that a trick to get more of the turquoise color in the blue channel is not to use "green noise reduction" in the compositing stage. Keep the ugly green picture :) but instead reduce the green channel in post edit with a curve (for example PS or Gimp).

[@CuivTheLazyGeek]

I really need to get my hands on PS at some point...

Salut Cuiv! Just a 5 minutes treatment and a little bit unorthodox... -blurX, noiseX, quick and approximative histogram transformation -pixel math (without Ha :D) R=S G=0.5*O+0.5*S B=O -then Lrgb combination with Ha as L drive.google.com/file/d/1bQHNixyQ7P1WtHNTuTCOCmJlXJgv9-Gl/view?usp=sharing Thanks for your great videos!
