How To Get Hubble Style Pictures From OSC Data! - Easy PixInsight Guide

[@AstroBackyard]

Just spent my Saturday morning with this tutorial and a big cup of coffee. Outstanding work, Luke!

[@lukomatico]

OMG! - I'm having a starstruck moment! 🤩 Reading that has absolutely made my whole week Trevor, thank you so much for watching and leaving a comment, you've been such a huge inspiration to me for an awfully long time now, without this getting overly long and taking up your time, I just wanted to say thank you!! I'd love to see your result from it if that was possible! :) Thanks again, and Clear Skies! Luke

Mr Trevor is now learning PixInsight? I've been STRUGGLING to learn it for some months now. Very difficult and slow. Perhaps easier, coming from PS.

Congrats Luke, you've captured the attention of one of the most prominent KZbin astrophotographers! Well deserved!

[@UssSamuG]

@@IcedReaver who is actually.. learning from Luke, so cheers to Luke! ;)

[@40Sec]

I don't have Pixinsight yet, but I just started using a cooled camera and have been wanting to try the simulated Hubble palette. This helped me feel a lot less intimidated at the thought of starting a Pixinsight trial, so I'll be coming back to work through this once my Sharpstar 61edph iii arrives and I'm able to capture some solid data!

[@lukomatico]

That's awesome to hear mate!! Good luck to you and clear skies 👍👍

[@Oamaruastro]

This was a phenomenal tutorial! I have always just figured that my data were no good when I could never end up with results like I see on other astrophotographers' pages, but now I see it's just a matter of getting better at using PI. You have shown me how to use quite a few tools that I never dared to touch before--very very helpful indeed!!

Hello Luke. Recently shot the wall using the same filter and this tutorial is exactly what I was looking for. Can't wait to try it out. And to answer your question, yes, absolutely the slower pace is much preferred. At times it is very hard to tell where the mouse cursor is at so we need a little time to keep up with you. After all we are here to learn and we cannot do that if we miss steps or got lost because things were moving along too fast. Thanks for doing this.

@@lukomatico Hey Luke! Great tutorial thanks, I did follow along ok, had one little niggle where EZ Denoise wouldnt work for me, (the Run bar at the bottom was greyed out!) but other than that, I got the jist of it! I just need some practice! Im not sure Pixinsight likes my data though! Photoshop doesnt have this problem, but when I load my image into Pixinsight (stacked from DSS), it appears extremely noisy, to the point of being almost pixelated! I can never seem to get rid of it all! But never mind, I just need more practice, probably me not doing something right! Well explained tutorial Luke, many thanks!

[@lukomatico]

@@SimonsAstro Hey Simon! On the TGV settings tab in EZ denoise, make sure 'run tgvdenoise' is selected :-) that should fix it! The noisy data thing can just be not enough data, high cloud, maybe some stacking settings even! - it can be a minefield but personally I'd only bother going rooting around in settings etc if it's every time you take data :-) Clear skies mate!

Hey there Mike! - That's great feedback mate, I'm very happy to hear it was easy to follow :) I hear you 100% regarding colour choices, it's a personal thing, and also perhaps a per-target thing too, undoubtedly the Cygnus wall came out strikingly with the colour choices, but a "normal" red approach would have changed the mood of the image totally :) - both valid approaches in my view! Thank you for watching mate :)!

Thanks Luke! I used the process last night on a rough test shot I had of The Bubble from last Summer. Just to get started. Before I take some wide field shots this year with a new Hyperstar. As you know the Bubble is mostly all red in a OSC, but your process makes it much more appealing! CS!

[@paulwilson8367]

I was able to get some 5 hours of RASA 8 data on this target and followed your tutorial. Was able to get those colors "mostly" similar. I did notice that, right from the stacked, raw images, your data was just better. Sharper and less gradient. Strange, you also live under Bortle 7 like me, and we used the same camera and filters. Perhaps it was just a night of poor seeing in my driveway. I would guess that my rig is "seeing limited" about 99.5% of the time. I may have to finally make the 2 hour drive to a place west of me to camp under significantly darker skies. 2 hours isn't bad compared to the 8 hours I recently drove to the dynamically dark skies (where I was rewarded with 3 nights of solid cloud cover). Thanks again for excellent tutorial. You used a couple of techniques and processes that I wasn't familiar with, so I will watch it again next time to try and remember the work flow.

[@lukomatico]

Hey there Paul! That's very interesting to hear, I do have some idea what could be causing the difference between our data, you might want to have a look into narrowband spectrum shift, because your system is f2 it will certainly be affected by this phenomena with the l-extreme filter - that's what I'd say is going on mate! I'm glad to hear you were able to follow along with the tutorial and learn a couple of things, that's absolutely awesome to hear! 😊 Thank you so much for taking the time to share your experience mate, it's much appreciated! 👍👍 Clear skies

[@paulwilson8367]

@@lukomatico You might be correct about that. The L-extreme was initially touted to be great for fast systems. But a number of people with RASAs are doubting it and saying they are not getting great results. The extreme may cause band shift with the pass too narrow. They are switching to the NBZ filter. I may do that too, but the NBZ is only made in MM sizes. My Starizona filter holder accommodates a mounted 2 inch filter, so not sure what will work. Thanks for response!

@@paulwilson8367 Hey Paul! - as far as I know the optolong l-enhance works well with f2, better than the l-extreme apparently for fast systems- I have no experience with the NBZ filter but IDAS make great stuff so no doubt it'll be a good option 👍👍 It's a bit of a shame to have to mess about like that isn't it :( All the best mate, Clear skies 👍👍

Hey mate! - I'll absolutely be doing that yeah! in the meantime, I do have a slightly more up to date version here, as part of this telescope review - kzbin.info/www/bejne/gou0aZ-grtN1Z68 hope that helps :-)

[@nickwest2022]

Hi Luke, Yes that video was much better. There is nothing more frustrating than watching someone demonstrate a process with the mouse flying round the screen so fast that you cannot see what is being clicked. Well done for being disciplined; saying what you are clicking as you do it. I'm a real neophyte to this field of Astrophotography. Indeed a week ago I wasn't even sure this sort of image was possible with a OSC, so your videos have got me very excited! I did find the assignment of the colours confusing until I read up about the Hubble palette. A question for you: you throw away the blue channel which seems sacrilege: never throw away data! I understand that the O3 signal is in both channels and if the peak position means that the light is shared equally between the two then there would be twice as much in the green as there are twice as many green pixels, but why not combine with b*0.33 + g*0.67. Is it that the peak is nearer the green so that it isn't worth adding the blue? Thanks, Nick

[@lukomatico]

I'm really glad you liked the vid Nick! - you bring up an interesting point about the blue channel mate and if you'll forgive me for suggesting yet another of my videos, then I'd like to show you my very latest version of this workflow! :-) kzbin.info/www/bejne/ppCxZX1jobWHha8 I hope you find it useful and relevant both!

[@nickwest2022]

Yes, I had already found that one and nothing to forgive! You are a natural at this and the odd little fluff only adds to the feeling that it is a couple of mates talking together. I'm still mulling over this false colour concept. In the end there is only two signals with that filter so synthesising a third feels a bit like cheating! Please don't get me wrong - your technique reveals more structure and beauty in the object and that's justification enough. Indeed, when I play with an image I always end up just pleasing myself, never mind the science. I just wondered if treating areas where both spectral lines are strong has a physics justification as well?

[@lukomatico]

Thanks for the comment again Nick! It's another interesting question really, I reckon rather than cheating it's just using the tools and materials available to you, you know? :-D I see it as being a bit like an artist mixing colours on his palette to create others, that seems to be a reasonable parallel to what we're doing here, in my opinion at least! 👍👍 Cheers for the thought provoking comment mate!

[@nickwest2022]

I love the artist's palette analogy. Keep up the good works and thanks again for these inspiration videos!

[@avukasin]

Once in awhile, a video really speaks to me... this is DEFINITELY one of those times. I can't thank you enough for sharing your time and expertise. This is a very well done lesson - thank you.

[@lukomatico]

You are SO welcome Alex! Thank you for that lovely message :) - I'm very happy you found the video good!

[@kamilkp]

I’ve watched this twice now. Gonna watch it one more time later today when I attempt to execute these steps on data I just captured a few days ago. Fantastic tutorial Luke and your final image is absolutely amazing! Subscribed and liked!

[@lukomatico]

Hey Kamil! That is awesome to hear, I really am glad to hear that you'll be having a go with some of your data, I hope you end up with a nice result mate! Thank you so much for your support by the way, that's fantastic of you! 👍👍 Clear skies and good luck with the process :-)

[@1203120377]

That was excellent mate! Great pace and really easy to follow. I don't do it the same way as I use APP. I tried a trial version of PI when I started AP a year ago which was not a good idea when you are trying to figure out which end of the telescope to use. After seeing this I think I will have to invest in PI as there is functionality like Pixelmath and starnet, which you can use as standalone but its integrated into PI which is very useful. Great job and thanks. CS Brad

[@lukomatico]

Hey Brad! - that's great feedback to hear mate, thank you! :) I 100% understand about pixinsight being a bit much when you are just starting out, I dare not attempt it for about 5 years I guess!! :D That said, now I'm used to it, there's really no going back! Processing in it has become a pleasure now :) Thank you so much for watching Bradley!

[@RigoFromSpain]

Really fantastic video Luke, can you tell me what background music you used ? Thx

[@lukomatico]

Thank you so much Rigobert! - The music is called 369 - Meditation Aquatic :-) Hope that helps my friend!

[@RigoFromSpain]

@@lukomatico thanks Luke

[@paulwilson8367]

Great video! Great processing in PI. I have this same camera and the same filter, so this is gonna be something I try as soon as there are some nebulae and no clouds! I am curious what your sky is like. I have heavy LP and usually ABE doesn't work for me. Also, some experienced AP'ers report that EZ DeNoise doesn't work so well for them linear due to abundance of LP. I will most certainly give it a go. Thanks so much!

[@lukomatico]

Heya Paul! - I hope the tutorial serves you well when the skies clear :) - regarding my sky, it's Bortle 7 here in Castleford re: processing, I often find ABE is a bit overzealous with default settings, but definitely sky gradients are easier to deal with on a long-ish focal length scope like the Esprit 120. - RE: EZ DeNoise - I've been lucky so far, it's always been great for me! :D - I've not tried it out in a nonlinear state yet, that could be interesting!, I know the tool it relies on, TGVdenoise works best with linear data, but, I'm all for experimenting with different ways to use tools! Thanks so much for leaving a comment mate, I appreciate it!

[@KopLamp]

I am almost tempted to buy PixInsight... but I will stick to the tools I know first... Siril + Photoshop. Nice tutorial mate!

[@lukomatico]

Hey Martin! - It's a slippery slope haha, I do think PixInsight is the #1 processing software out there - which it should be given the cost of entry! , but that certainly does not invalidate other approaches, as you have proved with your own beautiful images mate :) Thank you for watching!

[@DarkEnergyStudios]

Hello Luke! Do you still use the products from Topaz, since you found and use RC Astro’s apps?

[@lukomatico]

Hey there! :-) I tend to only use Topaz for terrestrial work now that I have all the RC tools, but it does still give nice results if that's all you have access to 👍 Hope that helps!

[@bennettdj100]

Awesome video with great info! I've got tons of L-Extreme data that I'm going to have to re-process using this now that I've got PixInsight. Question though, do you know why EZ Denoise won't let me execute anything except for Create Masks Only?

[@lukomatico]

Heya Derek! - I hope you get some excellent results when you reprocess your data! :) Regarding EZ-denoise, that's really odd! I'd just double check the TGV settings and MMT settings panels are both ticked to run, then it should be as simple as clicking run ez denoise right at the bottom in most cases, it'll make the masks automatically and run through everything :) I hope that maybe helps somewhat! Let me know if you are still stuck mate 👍 Thanks for watching!

[@mariospenard5125]

Lot of information but very well explained! Thank you

[@lukomatico]

Glad you enjoyed it Mario! Clear skies my friend!

[@freddheli]

Very well done. Just a quick question. When adding your stars back via pixinsight (Starless + star), wouldn't it make more sense to do a max (star, starless). If you have bright nebulosity in starless, is there a risk that adding the data from stars will result in brighter stars ?

[@lukomatico]

Hey there! - good question mate, I guess a lot of it depends on how successful Starnet was at removing all trace of the stars, - you could perhaps have a small bloom effect if star traces were left behind as you stretch the starless image further then add back in the less stretched stars, but I've never really seen results that are too objectionable for my tastes with the method I outline in the video :-) Well worth experimentation though should you wish! Thanks for stopping by! - All the best, Luke

[@stevepaterson2]

I like the idea of resampling the image before processing to, as you say, keep the process times down. This makes perfect sense for a demo but I'm thinking it could be the default way of working. When happy with the processed, resampled image, you could then apply the entire change history to the main image at the end. As an example, I resampled an image to 25% and applied NoiseXTerminator to it taking 15 seconds. The same process on the main image took 3 minutes! Quite a difference. Relies on ensuring we keep the full history of course. What do you think?

[@lukomatico]

Hey Stephen! - Sometimes if my images are oversampled I do resample down anyway as part of my usual processing routine, so it's totally valid I'd say! :-) Another good reason is if you find that processing images becomes a joyless grind due to how long certain processes can take to use then absolutely resample until you're happy with processing again, as you mentioned yourself, a 3 minute wait for a single process would be a bit of an enjoyment killer for many folk! Clear skies my friend!

[@Kay_jay_999]

Thank you! Learning something from this!

[@lukomatico]

Glad it was helpful mate!! Thank you so much for taking the time to comment!

[@trevorfonda6838]

This an absolutely amazing tutorial, I've never touched pixinsight before and was able to follow along with a little goggling and produce a great image! Thanks so much, please keep putting out content like this!

[@lukomatico]

That's brilliant to hear Trevor!! I'm very happy to hear you were able to follow along and create something nice! :-) Thank you so much for watching! 👍👍

[@Outlander1963UK]

Hi Luke, a great tutorial and what a lovely image. Having never processed any imaging before, I don't know how I will remember all this stuff once I come to try it for myself. May have to try and replicate yours and follow step by step. I now have all my gear unfortunately still all boxed as now have 10 weeks of night shifts. Again many thanks for this tutorial, they go a long way with understanding how it all works. As mentioned by another, think you are the UKs answer to Astrobackyard.

[@lukomatico]

Hey there Paul! :) That's really flattering to hear haha, the Astrobackyard of the UK, brilliant! 😁 I love to watch Trevor's videos! Regarding processing, it will definitely seem quite daunting now, but after a bit of practice it'll all start to fall into place! :) It's a good idea to follow mine or others, step by step as you mentioned, you'll start to familiarise yourself with it in no time 👍👍 I hope your shifts pass swiftly and you can get your gear unboxed and start having some fun! All the best mate, and good luck

[@richardprice4088]

Incredible tutorial.

[@lukomatico]

Hey there Richard! - Thank you so much mate :) Clear skies!

[@alessandrobarbato1978]

Fantastic video!!! i have a question, why do you don't Linear Fit?

[@lukomatico]

Thank you! - re: linear fitting, you can do that if you'd like! :-D I just prefer generally to do it manually myself for this kind of work 👍 Thanks for watching!

[@astrola1800]

This was a fantastic tutorial. The information was great, but as important, so was the pacing and the explanations of why you were doing what you were doing. Easy to follow and understand and really helpful for someone who is new to PI to really get a feel for how to use the different tools and how the apply them. I have been looking for a clear explanation of how to do SHO with OSC data and this was it! Thanks for taking the time to put it together!

[@lukomatico]

Hey Astro LA! - what wonderful feedback mate, I couldn't imagine hearing anything nicer! :) I'm really happy you have enjoyed the tutorial, thank you so much for trying it out and taking the time to share such a lovely comment! Clear skies 👍👍

[@paulwilson8367]

A problem that I have had several times now, is that EZ Noise Reduction doesn't always work. Half the time, especially with nebulosity, it appears to riddle the image with little black holes, as if I took a gun loaded with bird shot to it. I guess it tried to selectively make little areas dark and leaving others. Unusable. So wondering at what point after stretching to use traditional TGVDeNoise?

[@lukomatico]

Hey Paul! I'm sorry that you've been having issues with EZ-Noise reduction, not so EZ in your case I guess! :-( I'd be interested to hear how just using TGVDenoise works as EZ-denoise leverages that same tool for it's own noise reduction method - as to when to use it, I'd probably use it twice - once after my initial stretch right before using StarNet, and then again after channel recombination before saving out :-) I hope that helps somewhat mate, again sorry it's not worked out for you just yet! Clear skies, Luke

[@doubleastudios.official]

that has been really helpful, thanks a lot!

[@lukomatico]

Thank you very much indeed Adriano, that's brilliant to hear mate! :) 👍👍

[@MatheusSantanaMS]

Hi Luko, following your tutorial and using your image, after combination channels the image has pink and green not yellow and blue!! What am I doing wrong?

[@lukomatico]

Crikey! That's certainly not intended hey :-D I'm guessing the channels are getting mixed up somehow, giving the wrong combination!
