4:36 *pauses video. Re-processes every astro-image.
Hi Dylan, could you take a daytime picture of, say, a flower bed with your HaGO palette? You would know what it should look like (from your own eyes) and could therefore tweak the post-porcessing steps so that the HaGO image looks natural, and the apply the same steps to the deep sky images?
Great idea
You know, if you're computer is down, there's always.. visu...cough*.. visual.. astronomy.. cough*...
Reported for abuse !
Very clever, Dylan, and I like your workflow 7:40 . Very simple, like mine.
Thanks Chuck! Yeh I think some people go overboard with processing too.
@@DylanODonnell you guys have a lot of influence. You might mention how good data in is good data out. That’s the key to simplicity. This is a cool video.
@@GarnettLeary Exactly. I spend way too many CPU cycles and time on my data, and it’s still crappier than if I take a stacked tiff from Astrobackyard, Galactic Hunter or Lukomatic and just autostretches it.
Damnit! Now I heard “and we’re all going to...” and my mind already completed the sentence with Bintel. Your ad is working. Even though it is meaningless for me to order there. 😅
Great palette! Never would have thought about using a colour filter with narrowband filters!
Here I am boarding a flight to Hawaii and my favorite youtuber posts a new video.
Fly safe!
Planes have WiFi even spirit 😂
So why go then
@@williamgorham7339 my post came off wrong. I mean two awesome things are happening at the same time! You're right I do have internet right now though
That groove for the montage is a banger. As a new guy to the hobby, the question of color or mono for my first dedicated astro camera is weighing heavily at the moment. I'm still a ways out from pulling that trigger, but exercises like this really showcase the creative freedom mono allows.
Thanks mate :) I’m playing my new guitar on that track .. should be streamable soon.
Mono will definitely give you more signal, giving you a better image in the end. I went with an asi294mc pro(one shot color) as my first camera. The deciding factor was I'm still very new to image processing. If you're in the same position, it's a good camera choice. I do have the asi1600mm pro(mono camera with lrgb and narrowband filters) arriving tomorrow, after playing with the 294mc for 6 months. If you don't mind diving straight into the image processing, mono would be the way to go.
I'm still wondering if shooting in mono with a color camer while using filters is a huge difference to shooting with a dedicated mono camera.
@@Wombatzone31 its really not. Bit more work taking flats, and getting the final stack, but other than that not really. OSC and LRGB processing workflows (at least for me) are very simular, and then you also have the freedom of narrowband imaging without worrying about the CFA. If you can justify the price, then in almost all cases, you should go mono
@@johnschnupp9849 yeah I'm currently using an EOS 200D with a home made peltier cooler strapped to the back to help keep temps down and consistent. Works a treat but I'd like to get to sub zero temps for a sensor these days. I totally understand all the extra work... and money for decent filters to shoot in mono. Hence why I've stuck with color. And I've found I can get great detail with a HA filter on the camera too. That said I'm now stuck with choice due to pixel size and SNR... and cost lol
I will have to try this. Thank you are the man.
I have to say... I love your acquisition montages! How you can get stars from inside your observatory and still see your equipment... Nice!
Thanks! They’re a bit quick and dirty but I reckon I could get them clearer with some effort.
beautiful montage and tunes in the middle - could watch that loop for an hour - thanks Dylan
Quite literally just got off a call with a subgrantee based in Australia, posted a vid and saw this upload, lol. Flooding..... Thanks for the video on this true color narrowband topic! Best to you guys over there.
Thanks for the new info Dylan! Will have to try it to understand better.
Best of both worlds, detail of narrowband and colour au natural.
Good idea, but I just got a OSC delivered for comet shooting,
tip....7p comet goes in the same frame as the helix 15 June 2021,
I'll try this when all the smoke clears from the Western US. Thanks for another great video.
Heyy this is pretty cool. The only thing that might make it better is to use a solar continuum filter which is basically just a green narrowband filter.
Thought the same when I saw this video. Did it work out for you? - Too bad Baader don't offer these filters in 36mm.
Consider it done, I'm imaging Ha, G, OIII tonigth with a new target. Will be keen to see how this one goes
Interesting video. We can see green in the Orion Nebula.
I shall certainly give this a try as I am sure many will. Interesting idea and good to try new things. Just added OAG to my RC8 so maybe soon ☕️🙈
I shoot OSC and you've got me thinking, I could use my L-extreme and get the HA and O3 in one hit, then do a run with just a green filter. That should have a pretty good result with OSC I'm thinking
After watching this I was thinking same thing with l-extreme
You really do think out the box! and I wondered if that was you playing? Impressed!
Thanks mate :)
I subscribed just because you don’t end your astronomy videos by saying “Clear skies”. And original music to boot? Hat’s off to you, guv.
Thanks for the sub guvna!
Hey! Go use HaGO. Palettes and filter choice (outside of pure science imaging) comes down to what you consider to be noise. Light pollution being the major nemesis. In the audio world filters often take the form of tone controls or equalizers, they both introduce phase distortion. 8'd bet if you look a green filter monochrome data vs. Green filter rgb vs. Green with no filter you'd find some interesting differences. Mapping a continously variable spectrum into 3 discrete colors will alway be an approximation. I'm not sure where I am going with this, except to say you made my brain start doing things I hadn't planned on.
I think for "true" color, you would have to tone down the h alpha part in relation to green and O3, because human eye has low sensitivity around 650nm.
But i would still use h alpha as an luminance layer, for better contrast and details.
Well good thing the rain it's gone and you're able to something!! Nice video very informative!!
I've done the same thing before, especially with subjects with bright stars. My SII filter is CHEAP so it has very bad halos on bright stars, so instead, I use a green filter. I only do this when a bright star is in the image though. (need to get some decent narrow band filters).
Am not ready for this yet. Am still learning how to use my guidescopes. But I too am striving for "true" color images. At the moment, I've an 6D MK ll and an ASI M385MC, with an Orion Starshoot guide camera, an ASI 120mm guide camera, and an Explore Scientific ED 127 APO. Also have a Stellarview SVT 80mm. Finally broke down and got a Baader filter bay for my DSLR. Problem is I've not much time in a week, am blind in one eye, and can't seem to find my freakin keys in the morning! I love your work, and am clipping this particular vid to whatever is left of my brain. I want true color! I want clear skies, tow healthy dogs, beer, and cigs. Oh, and my wife too! Thanks again!
The green channel really brought out the reflection nebula by the bright star. Brilliant!
I'm so close to buying a QHY268M myself, but I have a rig that will easily cover the QHY600 sensor with pin-point stars...
...What's the market price for a kidney these days?
Really cool! I’ll give it a try
We will try this from Chile, I have a color camera but.. I can have the h-alpha and Oiii from the L-eXtreme and the G from the Bayer matrix without filter, just a few days ago i was trying to recombine the data from the L-eXtreme to get a hubble palette look but unhappy with the results.
Super zen chill soundtrack. I think you're on to something with this HaGo...
What a brilliant video! Fascinating!!
Sounds great I wonder if there is a way of doing with with OSC and the L-extreme
You have raised the ultimate question...what do Objects in the Universe "actually" look like in regards to their true colour ? If we could place ourselves in a cool Spaceship at the same point that our Telescopes places our simulated viewing spot , how different would those Images be ? Would they be different than what we get after Processing ?/SRK
Excellent presentation Dylan! I like your music too! Talented Bloke!😆
Wow, this makes so much sense!
I ensure you, the day I'll pass from planetary to deepsky, you'll know I'll be shooting HaGO.
I love this concept of true color in almost 2/3 narrowband! Can't wait to try. 😍
Great!
Cool! One day.....if it ever stops raining.....I'll give it a shot.
Hago is a go go tonight from Cornwall, UK....now what to shoot 🤔
Dylan is a genius
What are your binning preferences? I tend to 2x2 my RGB filters but not my NB. Would you 2x2 the OIII?
Great video Dylan! I always thought it was weird why people would use Sulphur as Green but it never crossed my mind to just chuck in a green filter. I just bought a dual bandpass filter for my ASI533 OSC so I guess I could extract the G from RGB and combine with my dual filter results, looking forward to trying this out, thanks for the recommendation!
Brilliant idea. Looking forward to giving it a try.
Hi Dylan, excellent idea. What is the feasibility of using H beta filter in place of the green filter for nebula imagery?
That'll work well too for emission heavy stuff :)
OK where can I buy these HaGO eyepieces? Does highpoint sell them?
When you said your watching star stuff it looks like your having so much fun. I wonder how much you edited out with you ninja secrets scene lol. .... great stuff thank you
Hehe
Awesome. I managed to get Astrodon 3nm Ha and OIII recently on EBay, but missed out on the SII. I'll try this out. Astronomical twilight ends in a couple of weeks here in Scotland though.
P.s. Byron Bay is the nicest place I visited in Oz. Loved it. 👍
In light polluted areas what will be the effect of fluorescent lighting which tends to have a green hue? I suspect this is a winner but for not so dark skies it may struggle.
10 nm ha ayeee,i just hue shift to my heart contemps.have ya tried nbrgb combination in pi ? this can be usefull aswell to get some natural colour look back, mainly usefull for ha and the red filter.
Instead of a broadband green, what about a laser filter used for scientific lasers at 532nm, would that give a cleaner image?
I'd love to test the theory!
I'll give this a go once Galaxy season is behind me. An interesting tweak on narrowband photography.
Neat idea Dylan and it definitely produced a more natural appearance! The only issue is you probably would want to wait for a true moonless night for the green. I will do this but it will probably be while since I before I image any nebulae again - unless I reprocess a previous image when I captured RGB stars. I love your background music! - Cheers Kurt
Hey Dylan, I reprocessed a NB image of the Seagull Nebula using your HaGO method and made a video of the results. I posted it on Twitter (&FB) and believe I tagged your twitter feed correctly. - Cheers Kurt
Very interesting results!!
I'm an OSC guy, but I will suggest this to some of my mono-shooting friends! Cool video. Hope that rain stays away for a while.
Nice one mate! Next time weather permits will give this a try! I generally do HOO, so will just add G to my Nina sequence...From bortle 6-7 in melbourne... so let’s see!
Would love to know! Good luck!
OK , so I've re-watched this Video a few times now and now I'm wondering about the feasibility of a "single" Filter that would incorporate Ha , O-III and Green . Would this work ? Any inquiries from Optolong ? LOL . /SRK
Dylan, have you tried colour balancing using statistics to detect the lowest score of your channels, and then selecting that as your default for LinearFit and dragging to the other channels to balance them all to match the default? Works well imho and i'm seeing more imagers doing this trick.
Will try this in Summer in London, UK on the North American and Pelican. Can't get much more light polluted than that! Will be imaging on a 1600MM so should be helpful to compare.
I do enjoy the look of an HaR/G/BO3 blend, though I've never used the NB exclusively for red & blue channels. Will have to give it a go
Thanks for the video! Looks like a fun idea to try - I need to increase my basic filter knowledge and appreciate the science/details. I’ve been happy with High Point Scientific and like that they communicate with you on order status without being prompted. I recommend them, too. Cheers with virtual beers 🍻 I like the psychology used, too. 😉 Smart!
Goodness, great job finding this unicorn pallette :)
Thx mate :)
@@DylanODonnell You've got me convinced, once my observatory here in Cape Town is built and setup(telescopes and mount has been in a cupboard for three years...), I'll probably spend my life savings on a mono camera and some filters... ¯\_(ツ)_/¯
Hi Dylan,
I decided to get into astrophotography after about 45 years with the hobby of photography. January of this year was a starting date of learning about backorder. Some of it was luck, because I learned of better options and canceled original orders. I had a Baader 8.5nm OIII CCD Filter - 2" Round Mounted on order until I was advised it was no longer available. The replacement is about twice the price and will be out soon, the Baader O-III 2" Ultra-Narrowband-Filter (4nm) - CMOS-optimized. Is this a good direction to go? I will be shooting ASI6200MM in bortle 6 on the patio from South Dakota…USA
Interesting filter .. can’t advise as I’ve never used it.
could you not use HA/SII/Green/OIII, mapping SII to the Red channel?
I like the HaGO palette for a number of reasons
1) i can justify not spending money on a sulfur filter $$
2) I cheaped out with a 5 position filter wheel and dont want to constantly change out filters when doing narrowband and true color
3) HaGO really roles off the tongue and sounds dope af
HaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGoHaGo
HaGoooooo! (screamed in the style of Hodorrrrrrr!)
I love your outro "Remember, everything is meaningless and we're all going to die." haha
The whole time I was thinking about this not working in cities. Maybe I can try even if I'm actually in a somewhat smaller town but a lot of hotels are in my area. They love their LED lights.
Great suggestion for a new color palette Dylan! If you haven't already done so, could you produce a video on timelapse photography with a DSLR? Love your timelapse clips from within your observatory, showing telescope and sky motion :-)
Brilliant idea!!
Meant to ask you Dylan. Why have you never imaged with a frac on your channel? Do you dislike fracs?
No I’ll probably use one for solar at some point :)
Not sure if this has been asked before - but for a OSC user would doing this with a Green and an L-Extreme (shot as separate runs) work similarly?
Some in the comments seem to think so. I’m not sure. Someone should test :)
Gotta pay the bills. No need to apologize for sponsors. Especially good ones. Sounds like your psychedelic music was channeling Tame Impala there. Oh yeah, the pic was good. Visual Astronomy Forever!!! 🤓
I'm still shooting OSC, but this video makes me want to try mono. I'm curious though why you use an APS-C sensor with your big focal length C-11. Wouldn't you get better image scale with full frame? Should I save my money and go APS-C?
Maybe but I assume the coma and vignetting would be even worse.. aps-c works pretty well :)
Would a RASA 8 need a high-speed green filter, or just any old green filter?
Any green :)
Hey Dylan, could the palette be applied to a colour camera as well do you think? Cheers.
No it’s a mono thing really
@@DylanODonnell thanks
Homie Dylan does this work on a OSC camera like the ASI294 MC PRO?
It's definitely an interesting idea. If I had a camera and stuff I'd definitely give this a whirl, doubly so because I definitely live in a light polluted area... Just a few km outside of the downtown core of my city in fact.. I wonder if it were mentioned to the Edmonton RASC folk if one of them might give it a whirl...
Good idea! Now someone needs to implement this as a multi-bandpass filter for colour sensors.
I would love to learn how to do something like this with a color camera.
@@starwatcher Someone would have to make a special filter. The Altair Astro quad-band and tri-band filters are the nearest we can get, but they don't do Dylan's trick with the broad swath of green.
@@michael.a.covington great to know. Thanks for helping me understand.
A very cool Idea, but the main Issue I have and I think most people living in light polluted areas that image in narrowband is that green is by far the worse part of the spectrum; it's were most of the artificial light sources emit. I think the closest I came to true color is by using a two filter set up with Ha and Oiii: Ha - OIII - OIII + .35Ha, the additional Ha in Blue to simulate Hb.
Interesting .. blue is always the worst for me. Green is always the best.
A new narrowband palette, and just in time for galaxy season!
Nice palette and excellent result.
you have inspired me to discover my own palette. so, whenever i get good skies, i will try: oxygen, magenta and green, and it shall be called, the OMG palette ;)
Hey Dylan
Very interesting it's supposed to be clear here in nz tonight I will have a go with ic2944 I already have the ha so will get the green and oIII might get the red and blue as well just to compare
I dont have Facebook what's the best way to get it to u
Cheers
Stu
Let me know how you go!
Keen to try as soon as my replacement guide cam arrives (yay for random equipment failures)
what a very clever idea. And easy enough to throw another run in, just for the green filter. I even have enough data on M42 to give this a go. You win a cookie, sir! I'll even take back a few of my aussie jokes :)
Hehe 👊🏼
🤯 Another great video! 😃
Loved the image as well as the music!
Sounds really interesting. I'd like to try it but I don't have any Ha Filters, lol.
Great video, your mix of humour and slightly more detailed videos make you my favourite on this platform. I'm just guessing that its one of your rivals that gave you that 1 down vote. That or someone's finger slipped.
I'm hoping to go mono soon when I start this hobby up again but have a 3 month old so right now so everything is on hold. One of the things I'm looking forward to is mixing, matching and just seeing what is best for myself. I'll be trying your suggestion for sure.
Thanks man :) and congrats .. having kids actually forced me into astro because it was something I could do after hours without making any noise!
Do you think that this'll be worth shooting with a DSLR and dual bandpass filter? (L-eNhance or L-eXtreme)
Are you asking if this target is a suitable target for that kit? Pardon me, I just am not sure of the question.
@@ronstewtsaw Just asking if it would be worth it
I don't think you'll get as sharp or dynamic a result.
@@DylanODonnell Still worth a try I guess 😄
This is fantastic, I just picked up an Oiii from HighPoint Scientific last week. In the spirit of cheapness, how do you feel about grabbing a #29 for Ha, and #58 for Green?
I'm not too sure about this, but I think that there are some 550nm narrow band filters out there. So in theory, couldn't you use a 700nm or 650nm Ha, 500nm OIII, and the 550nm green narrow band filters together with HaGO to achieve a full narrow band image? Any thoughts?
I wouldn't surprise me if the image was awful because the emission spectrum of potassium, lead, magnesium, calcium, sodium and a lot of other elements that are present in streetlights are usually very bright in the area of 550nm. You could maybe fix this by adding a little bit more OIII data, but I'm not too sure if it would be worth all of that effort. But it would be cool to see how the image would turn out.
I think you are right! I have no way to test because I don’t live in a city but it would be interesting to know how it performs in there. 550nm would be cool too.
Could not stop myself from giggling at the background music during the Highpoint ad... and the porn music during equipment preview! Also, really great idea regarding the spectral processing.
Hehe I wrote that porn music ! I wonder if I can select that genre when I upload to Spotify.
brilliant !!!
I gotta be honest, I thought you were leading into a joke with the HaGO palette lol. I'll give it a shot and report back to you in one of my videos, if I ever get clear skies again.
I have a zwo duo band filter every time I use it cant find any stars help
Longer exposures ?
Nice. I'll call this the Dylan pallette
Interesting approach
What sorcery is this? If I shot mono, I'd give it a try. Brilliant idea!
Hi Dylan!
I have a question that the softwares like Fire capture etc. connect to the astrophotography cameras via cable and can these software connect to Nexstar telescope also via cable?
I hope you reply:)
Firecapture connect to the camera. The mount connects to ascom via the USB/driver. Firecapture can indeed pulse the mount directly via ascom for auto guiding.
@@DylanODonnell by chance is there any software which can help me take exposures which can connect to my Nikon DSLR?
@@astroagashi2541 BackYard Nikon - I think It's free to try.
@@gazza9839 Thank You So Much:)
How different is this from HOO though?.. Considering how similar the green and oxygen channels are in the nebula that you shot and how little green there is in space, and you're editing out most of the green anyway..
I don't have a lot/any green data on nebula's. So I can't test out how different a green layer would be. But, so far.. with HOO, I've been able to get pretty close to the "true colour" look of some nebula, if you don't go crazy and balance the channels.
Bicolour is super flat.. the green definitely adds some natural character to the brown and dust tones.
What about visual?
I find HOO mono pretty close to the result i get with OSC. Tried posting a link to an astrobin example but it keeps getting deleted!
I saw it quickly :) it is similar but def a touch more data and dynamic range with the three separate passes. The detail in shot though is 👌🏼
I was searching for someone else to comment about HOO. Looking at the image here, I am wondering what the same data with HOO will look like vs HaGO. A really clever combination TBH.
