Another outstanding tutorial. I've only been doing astrophotography for about seven months, and as I am sure you are ready aware postprocessing is one of the biggest challenges for us newbies. I almost was able to duplicate your image following your steps, but I apparently made a few mistakes along the way. I will definitely be doing this several more times to get closer to your image. Please try to find the time to do more of these tutorials if possible. They are very helpful for people like me. Thank you again for taking the time to share this.

Nice one mate. Just stumbled across this video - great tutorial, well explained. I had a little play with my own data of the Rosette Nebula using this process. Data captured using my astro modded DSLR + optolong l-enhance filter. I had a lot more noise to contend with than you but after playing around I actually got an ok image. I could always run it through Photoshop to finish off I guess. I also signed up for the Pixinsight 45 day free trial earlier so will play with that soon too and see how it compares (I see you have a tutorial for PI too). Thanks mate.

[@lukomatico]

Hey there mate!! Thank you for your support 👍👍 Definitely the PixInsight versions of this tutorial are more flexible with regards to handling noise so you may find those a little more fun when processing data from your DSLR my friend :-) Thanks again for getting in touch by the way!

[@w.jeffreywilson3681]

Thanks! This is great; works well for me with the L-eNhance filter. Just a suggestion - as I understand Siril, in the Color Saturation tool if you lower the Background Factor to 0 it will tend to make color noise in the dark areas of the image worse when you increase the Amount (but will indeed create more saturation overall). I'm happier keeping the Background Factor at 1 or even higher to help keep noise down.

[@richardshagam8608]

Great video. I was able to reprocess my first images taken with an L-eXtreme filter on an OSC and getting some decent results. The real takeaways were recomposing the image as HHO in SiriL and manipulating the color saturation with the alternate controls which I hadn't noticed until this video. I wish someone would come up with a comprehensive manual describing all the features in SiriL--most of them seem to be Easter eggs waiting to be discovered.

[@lukomatico]

Hey Richard! It's superb to hear you enjoyed the video, thank you! I definitely hear you about the documentation, it's a lovely program and can do a lot, but as you say - discovering half of what is available is a task in itself!

[@richardshagam8608]

@@lukomatico Now that PixelMath is available in the new version 1.0, I tried making the red channel red, green channel a combination of 0.7*R and 0.3*G, blue channel G. That seemed to perk things up. And then I also tried the Contrast Limited Adaptive Histogram Equalization--something I hadn't noticed before. This also seemed to sharpen the image up, but has to be treated carefully. You might want to redo your video, now that these features, and more are out. Still, a great video as it stands.

Heya mate! :) I hope you are doing well, - With any luck Siril should be able to colour balance it nice and easy, one thing I notice between Siril and StarTools is that Siril is quite a lot snappier to use generally speaking, so it's easy to try things out and go back if they are wrong, with very little time lost :-) I hope it turns out well matey!

Otherwise, looking forward to seeing your tutorial on Siril and broadband data. I've been capturing both L-Extreme and broadband data (would like RGB stars) but some help on broadband would be nice.

Thanks Luko! Killer tutorial, helped me a lot. Ive just followed your steps witn a photo taken with a dslr and a lenhance filter and it worked like a charm. One question, would you recommend using for the luminance channel the one with less noise? In my case the red channel had more noise than the green, although it had a little more details and nebulosity on the red.

[@lukomatico]

Hey Pedro! Glad to hear you liked the video my friend :-) Re: which channel to use as lum, generally speaking the red is best as it'll be the most detailed, but do feel free to experiment - you may discover that another combination works better for you buddy! All the best 👍

[@jameswoods1939]

Never seen this approach before. The image came out wonderfully. I'll have to give this a try. I do have an issue with Siril however. It won't allow me to save files in tiff format which is why I rarely use this program.

[@lukomatico]

Hey James! I hope you have a good time giving it a try out mate :-) regarding saving as tiffs, that's an odd quirk I had no idea about! I assume you are just typing in you desired file name followed by .tiff to ask it to save in that format? Cheers for watching mate!

[@AstroPixUK]

Another excellent video Luke. Could you also do one in Astro Pixel Processor? Ive tried but cant seem to get the colour balance right at all.......

[@lukomatico]

Hey there mate! - I'm afraid I don't own APP currently, I may have to look into it at some point in the future though! :-) I appreciate you watching, thank you very much!

Nice one mate! good to know :-D

You're welcome!! :-)

That is an amazing little bit of processing Luke. I have been using an older version of SIRIL (double screen) and I am very pleased with the results. I image with an unmodded DSLR. Nikon D7500. Should I expect similar results if I upgrade SIRIL and follow your methodology? I think your OSC is also a CMOS, albeit not utilizing IR cut filter. Thanks for posting tutorials which use free processing software. Spent my astro budget to date on a very good mount and scope. Unlikely to upgrade to a dedicated astro camera any time soon.

[@lukomatico]

Hey there mate! - I'm very glad to hear you liked the tutorial :-) Thank you! Regarding similar results from an unmodded DSLR, I hate to be a downer but I'm afraid it's not possible really :-( the d7500 is a nice camera (I have one too!) but not really in the same ballpark as a true astro camera when it comes to nebulae astrophotography, I'm sorry if that's a let down to hear. You may have some good luck shooting the brighter nebulae however such as M42! - certainly you could shoot plenty of galaxies and globular clusters also :-) All the best, Luke

[@febsat]

@@lukomatico Thanks Luke. I always appreciate honesty. I'll start saving my pennies, oops, in Canada here so we no longer have pennies. I'll save nickels instead; get the dedicated camera that much quicker ;-)

[@jodyschultz5870]

What mono camera and narrowband filters are you using to capture the narrowband data?

[@lukomatico]

All the data in the tutorial is OSC data Jody! :-) Sorry for any confusion!

[@penguin242]

Thanks for this tutorial! Is there a reason you don't use the photometric color calibration?

[@lukomatico]

Hey Tony! Glad you liked the vid mate :-) RE: PCC, I don't use it for custom palettes, it's only really useful for standard broadband targets in my experience :-) Hope that helps!

[@charlesowillford2474]

Question. Instead of using separate channel; can you use the script that creates Ha and O3 and then use those when you recombine?

[@lukomatico]

Hey Charles! :-) you absolutely could do that I bet, great suggestion! Thanks for watching and clear skies 👍👍

[@charlesowillford2474]

@@lukomatico Where did you post that video. LOLAlso, below one person labeled what you had done as HHO? That is incorrect; isn't it? Or is it correct? I say you did RRRG palette? H and R are not identical are they??

[@febsat]

Hi Luke. I would like to ask a question related to SIRIL. Could you give a little tutorial on processing multi-sessions with SIRIL? I have captured data over multiple nights on a rather interesting image, but cannot figure out how to add it all together within SIRIL. Thanks

[@lukomatico]

Hey there mate! - This is something I'm not too sure on how to accomplish in Siril if i'm being honest with you! I tended not to use Siril for stacking, usually on multi-night session's I'd just lump everything in DSS at once at let it chew through it! Have you tried perhaps stacking your data sets individually, e.g night 1, night 2, night 3 etc, and then take the master files and stack those together afterwards? I'm sorry I can't be much help with this one, my apologies :-( All the best, Luke

[@febsat]

@@lukomatico Hey Luke, no need to apologize. I have thrown the question out to another fine astro photographer who has given me some tips; much along the line of what you are saying. I will definitely need to do some experimenting. Sometimes I wish those nice software packages would come with manuals or detailed tutorials. There are a lot more intelligent people out there than myself who are muddying along trying to figure SIRIL out. Regardless, it is an absolute game changer for beginner astro imagers who have good gear, can gather the data, but fall short on the processing end. Right now, that's me ;-)

[@slzckboy]

just reprocessed my image of sadr region.. ... Thank you :)

[@lukomatico]

That's awesome to hear Rob, I hope it turned out great for you mate! 👍👍

[@spawnoverkil4206]

Did you stack it normally like any other osc?

[@lukomatico]

Yes mate! :-) just like normal 👍

[@woozii.capalot]

I’m tryna take a picture of the andromeda galaxy with my iPhone n a telescope but when I put the picture in deep sky stacker, the stacked image comes out all white n you can see the galaxy, n when I put it inna editin app it when I edit it doesn’t change. Any way I can fix this?

[@lukomatico]

Hey mate, sorry about the late reply - if the individual images aren't whited out then the result should stack OK with all default settings - if it's coming out white then it sounds like it's using additive stacking potentially - try switching it to averaging or kappa-sigma clipping Hope that helps!

[@woozii.capalot]

@@lukomatico I tried that but it didn’t work. It feels like I’m the only one havin this problem cuz I been lookin but I can’t find the answer. I even went on astrobiscuits discord but everyone just ignored me. They answered everyone else’s questions but just skipped mine

[@paulwood6729]

I'm thinking this would also change the colour of the stars, not that you can really tell! If you created a mask of the stars (obviously I'm going beyond the video), applied that to the original image and blended that colour in, wouldn't that bring the correct colour back to the stars? I'm thinking that if someone took a false colour image with a mono camera, they could also take 1x each of RGB to get the correct star colour, merge them into a single picture, apply a star mask to that and blend the result onto the main picture using something like Colour Dodge to bring the correct star colour through. Noise in the RGB image shouldn't matter as you're only after the colour. Would that work?

[@lukomatico]

Heya Paul! - That would be ideal for sure! unfortunately though I do not believe there is a way to create a mask yet in Siril itself, so would probably need doing in external software :) I do something similar in my PixInsight tutorials using StarNet++ which is now integrated into it, and it does work well! re: the RGB stars idea, it does work mate yeah! :-) good shout! Thanks very much for watching!

[@TwoHandUke]

Hi there, Is the data still available so that I can follow along? The link seems to be broken.

[@lukomatico]

Hey there! - I'm so sorry but it does indeed appear to have gone missing now, my apologies about that - I keep running out of room on my online storage so occasionally older stuff gets cleared - I'll check if I still have the right files and reupload if so, but I'm honestly doubtful I still have them :-( I've got other data available though from newer tutorials that you could no doubt download and use just fine! :-) Good luck!

[@TwoHandUke]

@@lukomatico Thanks for that. I found another file for you tutorial using the Cygnus wall and following the tutorial using that. Many thanks, THU.

[@OVRCOME]

Any chance you would redo this video again now that SIRIL is more powerful?

[@lukomatico]

I will likely do that someday mate, sorry I can't commit right now though 🙏

[@MegaMichaeltodd]

The median filter is the noise reduction tool. Also, as far as I'm aware, the colour calibration tool is for the background and white balance, not midtones. Ie, select the middle of a star. On your initial stretch, you should use the asinh stretch as it retains the colour data more

[@lukomatico]

Hey Michael! - I hugely appreciate the tips mate, thank you! :-) I've tried the median filter before but it seems totally indiscriminate in it's application so kind of blurs the whole image in my experience? I guess that could be still worth it if the noise was particularly bad though! - re: asinh stretch, I should give the process a go with that at some time, it does work well! :) Thanks very much for watching and leaving your thoughts and tips mate

[@MegaMichaeltodd]

Try putting both sliders in the middle, 5 and 0.5 iirc.

[@MegaMichaeltodd]

Also, you can do a per sub background extraction that works wonders as the light gradient on a single sub is easier to model than a compound expression needed for a gradient accumulated over the whole night. The scripts are available from the borealis lite channel

[@paulwilson8367]

Have really been learning from this technique. We know that when we use these NB filters for OSC images, that the nebula will be enhanced but the broadband stars will suffer. The idea comes that why not get separate image for the stars not using the NB filter so that the stars get real colors? Then combine the nebula with the stars. It ends up being a bit tricky. Perhaps a guy with your processing skills could pull it off and show the rest of us how to do it?

[@lukomatico]

Hey Paul! - what you describe is certainly a doable technique, admittedly though much easier in PixInsight! :-) I'd probably need to leverage Starnet++ as a standalone program to make it a workable technique in Siril, admittedly though it's not something I'm very familiar with doing :-) It may be an idea to visit some day! thank you for watching and for the quality suggestion, it's appreciated :-) All the best, Luke

[@georgedicker9789]

This is amazing, nice one. How did you get 10 min exposure without getting thousands of stars, I recently did this image using 5mim subs and the stars take over the images

[@lukomatico]

Thanks mate! Just a deep FWC on the camera and a low-ish gain setting makes it so the stars aren't absolutely nuts! IIRC I didn't shoot this with the fastest of scopes either, my RASA would probably not work good with a 10m sub by comparison, hah! Cheers for watching :-)
