This is a great video. You appropriately quipped about the importance of taking the time to consider the objects we’re photographing to consider the nature of the object itself. Your recent reference (and shameless plug) for Burnham’s Celestial Handbook prompted me to resurrect my copy from the shelf. As I began reading into objects I’ve been photographing it was like I’d been shown the objects in a different manner. Modern tools give us the ability to examine celestial objects across multiple data ranges. Rather than scrolling through images there’s substantial value in looking at the nature of an object based on the observable information contained in the image. Good video Sir. Cheers!
Thanks for keeping Robert Burhams's efforts alive in our memories. Before the internet was online for most of us then, we used charts in Uranometria to find where an object was, and Burham's Celestial Handbook(hard cover)to tell us something about it. That was often the limit of our knowledge out in the field. Rest his soul!
I simply love his attitude. I've watched every episode
Thx mate!
Same. It helps make this hobby fun.
Very good job connecting our astrophotography to astronomical science. It's not just pretty pictures!
Great video again. Putting the accent on observation and accompanied by serious and valuable questions make us learn so much more. You went way beyong the simple imaging process. Thanks for sharing.
This is the first year I have attempted the Horsehead (no idea why it took so long) and I am pleased with my initial results. Love this video and we both know you have just begun to scratch the surface of all that is in that image. How cool would it be to do a 3D trip around The Horsehead? Glad for your success. May many more sponsors throw themselves prostrate at your feet.
I have a 6' SC-telescope on a alt-az-mount and I screw my daily DSLR - not modified - behind it. I process everything on my MacBook which is struggling with more than 80 Lights, using just Siril and Lightroom - and I still caught a glimpse of the horssehead-nebula! I was extremely happy with it knowing the limits of my setup. Same with the "colums of creation": Not fantastic, but definitely there! This makes me enjoy your fun and interesting videos even more, being more aware of where they are to find. But since clear skies are rare here in the middle of Europe I don't plan to invest a lot more in the near future. Keep it up and thanks for your efforts!
Great Stuff Dylan I really enjoy imaging the horse most seasons and this deep dive was GREAT.A nice difference compared to other clips on just the imaging only a nice way of looking at it
You have excellent and informative videos and it frustrates me that your reach isn't much wider. You and Trevor from Astrobackyard are my primary channel and you both have engaging content, although different. The production quality of your content is excellent and that leaves me frustrated that your audience isn't broader. I enjoy your videos and I always recommend your page when given the opportunity.
Wow just came across your channel and I love what you do! These deep dive videos are hilarious and informative. You deserve more subscribers for sure! Also id enjoy a deep dive into my favorite dso the veil nebula complex sometime ;)
Oooooh baby that hair is looking good!!!!! Guess you need to let me know what case of beer I’m buying you?
Oh I will Craig. This is happening.
Supercool video. I think that the shinning effect you explain that the star sigma orionis is producing over the rim of the horsehead dark nebula is the same that can be seen along the top edge of the elephant trunk nebula, as result of the ionization produced by the star winds from a blue supermassive stars triple system that can be seen in the center of the bigger rounded complex of that nebula. Another beautiful nebula example for a deep dive like this one you’ve made here 🙌🏻
This is an excellent video Dylan I like how you took the time to explain what you were doing in a way easy to understand for the lay person.
Thanks! It’s because I’m a lay person too.
I agree totally with Burnham. I failed to visually observe the Horsehead with an 11" Celestron using every damn filter (and no filter) out there. First time I imaged it with a 15-second sub (original Hyperstar), there it was, clear as day. Never looked through an eyepiece since then.
Haha yep.
Nothing like a deep dive into a horse to relax on a Friday
Agreed
Why does a purely visual guy like me follow Dylon’s videos? I dunno but he’s entertaining as heck and the intro to starstuff starts my weekends while I’m making breakfast 😅 you can’t help but jam out to that intro.
This was fantastic!! Do you have a playlist of all your deep dives?
No .. but the video I just posted is a deep dive :)
And there was me thinking that those lines within the nebulosity was just my poor data acquisition and camera. Thanks for that one 😁😁
Thanks for this video. I often try to stress to students that the sky has depth. The parallax feature is a great way to display that fact. I’ve used the annotate script and never knew the parallax was there. Thanks again.
Nice video with some detail about the Horse Head nebula Dylan!!
Pretty neat video! I didn't realize those tools were in PI. Sweet.. On a side note, I like the new look- You're like the Dylan version of evil Spock! :-)
Dylan..that was super fun! Great job. I hope you referring to some other Greg. HAA!
Cheers -Greg
Hehe
Very cool. Another great example of how little I know about Pixinsight.
Very very interesting dylan !
Getting to know approximate brightness and distance in this way is so impressive.
Many thanks and best regards from Germany.
Erich
Another great vid Dylan. Thank you. Like the new opening sequence too.
Hey Dylan, this is literally my favorite Astro channel! Love your work. Just curious, what’s your image scale like using the 268M and the C11? Are you binning and if so what kind of hit are you taking on resolution?
Keep up the great work!
I haven't watched the full thing yet but I feel this could use a good office space reference... Deeper and deeper, way down
I dream of photographing this nebula. One day… one day
Lol - some day the kids and grandkids are going to see dad’s hobby videos and be so proud! Does Anna laugh or roll eyes? LMAO! The depth and 3D way of looking at it like that is what makes it fun to stare at for me, too. A lot to take in and it just doesn’t get old. ⭐️ 🔭
I asked her if I should skip chess club this weekend to go to astro society instead and she laughed. She laughed in my face.
What about the xmas cluster? Quite the same to the horse head, except the cone would be a pawn on a chess board : )
I seen an images sometime back where there were few very faint galaxies behind the horsehead nebula 'red Ha fringes' background. Try to find that image again I guess it was on Astrobin.
One of your best videos. Keep em coming like this one.
When it rains and you can't image, do you ever go in your outdoor space pod and pretend you're playing hide and seek as a kid and no one can find you? I would.
Great video Dylan. As a Scientist myself, I like the deep dive you've done. Great educational video!
Great info on the Horsehead Dylan. One of your best videos!
Thanks Christos!
I just changed my battery out about 3 weeks ago. I switched to an 18ah outdoor gear; it doesn't look like you had a dakota? Do you have problems with the magnetic contacts? There's been a couple of ideas lately to get that reliable - stiff wires/cables and using copper ground straps to hang the magnets are 2; I started doing the later. I'll keep an eye out for striation, I think I've seen it before but thanks for calling it out as a feature as well as where it's coming from.
Great videos and solid advice! But, I've been wondering how's that new mount working for you?
It’s amazing! Never an issue :) absolute beast.
I deeply appreciate everything about you @dylan. Deeply.
Thanks Dylan, you've sent me down a rabbit hole trying to get the Gaia databases for Pixinsight! only 30gb or so left to download and then I can see how deep my images go.
Haha it’s a monster hey. Then they just dump another one in a couple years 😆
Fascinating! Most processed images of mine don't solve but when I have I can see some very distant galaxies, as dots, by using pixinsight. I'll have to check that parsec part out.
Cool and insightful vid Dylan. I had no idea PI can do the star labeling stuff you did art the end. Cheers Kurt
It’s cool huh? :)
This is really cool Dylan. Entertaining but also very educational. I had never though tto look in to my own images in this way but it has struck some curiosity with me now. Was thinking about this while going through my thors helmet edit last night, do you know any good sources for learning more about this aspect of things? im one of those who was interested in the science when young but went another direction, then came in for the pretty pictures and now slowly easing in to both the imaging and science in my 30s
Deeeeeeeeep
What did Greg do by the way?🤔
He knows.
Can you make a video showing how to calculate the spectral resolution of a given telescope? What parameters do you need to know to calculate what range of the electromagnetic spectrum a lens can capture and differentiate between frequencies? How do you calculate what those frequencies are for various lenses?
Great vid, really makes me want to go and have another go with my crappy equipment to image the horsehead, but we haven't had a clear night in 3 months. Bloody fog and rain!
It’s been brutal
You are a pure delight Dylan 👍
One question: Would it be possible to expose such that you could make out the individual stars in the star systems of for example the two outer stars in the Orion belt?
thanks to your vids i have improved a lot specially with tracking, need to get a light pollution filter next. keep up the great work.
Hey good work!
Hi Dylan,
Thank you for the interesting and fascinating astronomical insights into the subject. This really takes your already great videos to the next level!
LOVED the Parallax insight. Thanks!
Really nice information on something I really never thought of before in an astroimage .Thanks
I was wanting to hit this target with the 1600mm, i got the camera and the LRGB filters but they didn't send the filter wheel or the HA filter. Think i have to try this again next year. Unless magically the parts pandemic is fixed, i mean we do have one less country getting chips, so that helps.
ill watch it later
lol
No. Watch it now.
Would it be possible to do something similar to the Hubble deep field image? I know we can’t replicate Hubble power, but if you dedicated enough time to a relatively empty region, would you catch photons from distant galaxies? Or are they just too faint?
Way to go Greg!
Well! I'm Greg, and I have no idea, but I'm sure it was good. Nice video Scrappy.
Love the hairdo, your rocking it as if your a visual astronomer 👍👍👍😎😎😎🎉🎉🌛🌜🌛🌜🌛🌟✨
I sense I'd better not Google with search terms Greg and Horse! Really great video as always Dylan, I enjoy your analyses combined with the dry don't give a sh*t humour :D Talking of which, yeah point taken about mentioning the distance to objects in videos, I'm guilty of this myself and I guess it's only good for placing the relative distance of objects E.g. the HH is closer than the Ring nebula etc.
Haha I just glaze over when sciedu start talking about distances.
Really love this video it carries so much information which i love about astrophotography.
Wow!! My little brain could never, although it wants to!
More deep dives please. I had no idea about the details you have just revealed.
Brah! You’re in the wrong field! You should have been in stand up comedy! Thanks for the info and laughs!
i read somewhere that the horsehead itself is 4 light years tall so it can't be in one system. or did i dream it?
Great video and it made me look at my Ha image of this target and now i remember why i love this hobby so much.
I didn't look it up but the Sigma Orionus trinity are made up of stars ~15-30 times bigger than the sun so I imagine it's sphere of solar influence is quite large!
@@DylanODonnell as you say the distances and sizes are too much for us to comprehend. for instance the shadows are probably hundreds of light years long so would have taken hundreds of years to cast. crazy talk as shadows form instantly surely :)
The streaks you mention i have noticed before but now i am going to look into that further.
@@TheRuminator Let me know what you find out.. those streaks must be huge (and possibly moving) and the magnetic forces / solar winds responsible must be incredible.
hi Dylan, I’m still a beginner in astronomy, only been gazing for about a year, what exactly is the horse head nebula? it looks like a giant shadow among all the reflected light.. i know it’s probably a stupid question but what’s it made of? and if it’s a shadow, what the hell’s casting it? i’ve watched nearly all your vids, i have a nexstar 8se and haven’t done any astrophotography… yet… but…. yeah, we’ll see if i can afford it… not yet i think.. thanks for your great input by the way…
You will be able to get an image of the Horsehead nebula with your 8SE and with the appropriate camera. I was taking an image last night but it sure wasn’t as pretty as Dylan’s!!
The nebulas a deep-red color that originates from ionised hydrogen gas (Hα) predominantly behind the nebula, and caused by the nearby bright star Sigma Orionis.
Really nice video Dylan. Something new and very interesting to do using pixinsight
Okay, so does Pixinsight refer to a catalog of parallax for each of those stars or does it measure it? You can see where I’m going. In order to effectively collect data for parallax measurements you have to compare two images collected 6 months apart. (The base of the triangle is the earth’s position at opposite sides of it’s orbit - 2 AU Astronomical Units). I don’t think you can calculate parallax from a single image. What’s going on in your parallax discussion?
It’s Gaia data.. it’s a mission that’s being gong for years and years :)
Finally we are seeing some real montage! 😎
Is that the Lunatico Cloud Monitor you got mounted to your fence? How do you find it works?
I wish I could export the weather data off the device somewhere usable (like my website) but apart from that it’s good to check without going outside and has a semaphore file you can use to trigger the dome close if it detects rain.
Entertaining , educational , A good laugh . Thank You / BTW the beard makes you look more SCIENCEY /// HOW ARE LIKING THE eq-8 Rh
Best mount ever :)
cool thx dylan. I can now use all the useful info you splurged out in this video in my own video (evil laugh) and bc this vid is quite an old one you'll probably not read this comment and you'll never know (even louder evil laugh). BTW theoretical question: in an infinite multiverse then there must be a universe where you did a deep dive into uranus without any crude gags. I honestly don't think that would be possible... I only mention this bc if I'm right then we've proved the infinite multiverse theory to be a load of cack. Good job.
Bahaha I only just saw this comment. Dude steal as much as you want :) I consider all my astro content public domain and copyright free. Huge fan. Let’s collab on something sometime. In this universe preferably.
Informative and entertaining as always, m8!
thanks Pete!
Can you upload a 10 hour video of you saying "vendor"?
Very interesting Dylan. Maybe it is possible to make a stereoscopic image based on the parallax numbers giving the illusion of 3D. You may need a similar image from the northern hemisphere to get some angular separation. It may be to little, what do I know 😂. Yet taking the astrophoto hobby to a new level introducing a “new” software for everyone would be cool 😎. Thanks for your videos and keep it up beware not to burn out as it seems to be popular these days 😋.
You’d be better off taking the images 6 months apart I think, unsure how effective that would be though
High Point Scientific do not sell any of their products overseas anymore, even their second-hand stuff.
Amazing Video Dylan!! Nice Image!👏
Cheers man!
Thought it was going to be a scene from Cheech and Chongs movie the Corsican Brothers
I'll extend this haircut challenge. Case of beer if you keep it grown beyond easter .. Jesus style to Christmas. That's assuming Byron isn't underwater by then.
Tempting .. but I’m not sure I can go without sex until Christmas.
Lovely weather. Dylan, you have gone deep up into that Horse Head. Hope you washed your hands.
Interesting video, Dylan. A lot of stuff I had no clue about, but then I'm still not in a position where I have anything images coming in, maybe $6,000 USD from now. :) But, in the meantime, I'm really appreciative of what you're putting out.
Question on your rotation theory.
If there is a north a and South Pole, they would be the stationary poles. So they will produce the magnetic lines of flux. If the star rotates, how fast does it need to rotate to see the lines move? I would think that if a star is to rotate it needs other forces acting upon it to rotate. So my question is, what forces have enough gravity to make the star rotate?.
Great video as usual!
Can a longer exposure or integration time reveal dimmer stars or is there a hard limit base on aperture or some other physics?
Both!
Maybe revisit your 3D render video but combine that parallax data for a more realistic star field?
I have 100% been thinking about this.
@@DylanODonnell Ha! I've heard it said 'Great minds think alike' but mine is slipping so it can't be true.
Dylon, when you say your favorite quote at the end of your videos,
Is it sarcasm? It is a fact that nature dies, but it did serve a purpose
Ah wth am i going on about
"Everything is meaningless, and we're all going to die"
What is the point of existence, and does it need one to be as lovely?
@@DylanODonnell existence is a great thing, as living creatures and organisms experience certain phenomenon, where as no life at all there wouldn't be an understanding.
The universe as whole constantly changing, as it expands certain galaxies die off and become something else. Point is, energy has to go somewhere. Meaning of life would be to train your energy so when it leaves your flesh, hope it would move on rather than be static.
This kind of video is really interesting.
Hey Dillan, your image specs said 640mm for the RASA. Do you overestimate everything by 20mm? :)
Possibly 😆 with the cheaters crop it’s probably way over 700!
Even your horse in the cowboy image is ashamed of you're hair... Super deep dive into the horsehead nebula with more info than a bucket of sardines...
Its one thing to admire hours of exposure time in a image but its totally different to actually understand, like you said what is going on within...
Love it, you're a bloody legend
Also, what's the go with Star Stuff Festival, any chance for this year? 🤞
The best yet....so true!
I felt that rain
I'm dying here.
Dylan looks like Chuck Norris )))
here is an idea for a video, create a 12 item list for 12 month of the year for a beginner astrophotogropher with modest equipment, and how to do it.
Now it would be cool to use that data and export the stars as layers based on distance and then make a 3d animated photo in say after effects or something to make it have depth based from real data
Agree!
Very interesting.
One of your best.
You're seriously looking just like Dave Grohl! Although where he sees the Deepest Blues are Black, you might reveal something more interesting with your big scope and a little extra integration time 😅
I’ve got another confession to make…
imaging using this paralax data to create layers of stars to make a 3D video of this stars mooving in front or behind the object
IMAGINE*
You have a nice sink. Oh, and this video is absolutely great. Thanks :-)
Thanks! You should see the bathroom.
Hey Dylan, I love money too!
When you said "this star is responsible for the brightness". Aren´t we talking of a system of at least 6?
Yes... although it was first described as trinary early on because of the 3 largest ones (I added text on the video as I said it :)
