Take Better Milky Way Photos in 2020
Вставка
- Опубліковано 7 сер 2024
- In this video I'll show you two ways to capture better Milky Way photos in 2020!
The first method is called photo stacking. Rather than taking a single exposure, try taking 5 - 20 exposures. These photos should all have the same camera settings and be taken immediately one after the other. You can then load up these RAW photos in Adobe Camera RAW or Lightroom and do some basic edits. Finally, use an application like Sequator or StarryLandscapeStacker to stack all the images together. This will create a much cleaner final photo.
The second method requires a star tracker. This is a simple device that will slowly move your camera with the speed of the stars. You'll need to take one exposure with the star tracker turned on, and one with the star tracker turned off. Once you have both photos, you can edit them and blend them together.
For more information on this whole process, check out my other videos on UA-cam or my full courses:

Hi Peter, Sequator is a great stacking tool, even tough I would recommend to shoot the foreground separate from the sky and merge both parts, you´ll get a way better and sharper foreground.
One major step to clarify: disable all noise reduction before outputting your original images and bringing them into your stacking software. Otherwise you're throwing away a ton of information hidden in that noise.
Peter Zelinka is the man! Thanks for sharing your knowledge and experience!!
I'm Japanese.
Milky way in Japanese is "Ama no gawa(天の川)" .
This means "River of the sky"
(天＝sky, 川＝river)
I'm Chinese.
Milky way in Chinese is "银河" .
This means "River of silver"
(银＝Silver, 河=river)
@@jxmai7687
Oh, wait. ginga(銀河)/銀(silver)河(river) ) in Japanese is "Galaxy".
Then, what do you say Galaxy in Chinese?
@@japanesefolkstories811 Galaxy 星系 but many people think Milky way is same as Galaxy, that is way be mix up in writing.
Thank you for sharing what it means!
So interesting, in Turkish it means Saman-yolu Galaksisi which translate as Straw-road Galaxy. Now I am wondering how it translates in other languages
One of the best and informative videos about a specific Topic of photography i ever witnessed - awesome!
Incredible video, very glad UA-cam recommended this! I'm somewhat new to the astrophotography scene and have been thinking of investing in a startracker for the past few months, I think I might have to now, wow!!! And those images at the end, OUT OF THIS WORLD!!!
Thank you, Peter. Very informative - I also appreciate your speaking voice. It allows me to focus, absorb, and process everything better. 🙏🏻
I really like your videos! Amazing quality and extremely educational! Keep it up Peter.
One of the best tutorials on amateur astrophotography!
thank you youtube for recommending this channel to me
Oh my gosh! the thumbnail is what made me click - I'm literally 25 mins away from the Toadstool Hoodoos!! This is so inspiring, though. I've been looking at different lenses and stuff, would love to improve my photography and videography and since I'm out in the desert, I'd love to capture the stars...
Thanks for the great lesson and tips on stacking. The star tracker looks like it provides the best foreground detail with longer exposures and amazing results. Thanks and take care. Mahalo and Aloha.
A big thank you from Seattle. Another fantastic video😎🌌!
Thanks Peter. Astro beginner here. Hoping to get something this summer that improves upon last summer's average results. These tips will help.
Great job and good learning from you Peter!
Well done Peter, as a newbie to night photograph this has been very helpful.
That mass effect background music 👌
Thanks, Peter, that was fantastic, very helpful
Excellent. Looking forward to more astrophotography tips.
Just watched your Neowise editing photo and now watching this. Trying to get into Milky Way photography this year, and this is quite helpful.
Gracias Peter, muy pero muy útil tu vídeo, te lo agradezco muchísimo, eres de lo poco y nada que realmente muestra intenciones de enseñar sobre el tema, que hay en la red. Saludos de Chile
Brilliant Video Pete I have lots to think about
Thank you!!! what a great way to easy understand this video. you did explained that well.
Great video! Thanks for sharing all these tips
I really appreciate your amazing videos
Great tutorial, good job! Amazing pics aswell. This will definitely be handy for elevating my astrophotography to the next level next season! Oh and if you happen to see this Peter, would you mind sharing the playlist for this video maybe?, It's amazing!
Looking forward to your 'I've Brought A Goto' video.
Thank you for this video! I have recently started astrophotography and have been having lackluster stacking results. Your suggested settings in Sequator are helping!
Love your tutorials
Fantastic info here, thank you!
Thank you for sharing your expertise.
For me.personally this kinda video helped me more than any of ur video coz I am beginner...and this is best video for beginner
This is a superb tutorial, with clear concise dialogue at an even pace, and a good soundtrack too!
Glad you avoided the hype I see in too many YT videos.
What was the music Peter?
Cheers and thanks from Montréal!
I also want to know soundtrack. This video is good for going to sleep, that soundtrack and explanation
Nice video Peter, I dont have a star tracker yet but this this is compelling for these type of shots.
gotta love that implementation of the mass effect OST
Very helpful! Thanks for posting.
Thanks for the right click shortcut in sequator. I’ve just been resetting when I mess up
Thanx for a great video and very pedagogical!
Awesome diy mang 🤙
Nice info, very helpful.
Great vid man
Great tutorial. Going to Colorado to shoot some stars, will be first time. Shoot Nikon and use a Mac so I am hopeful it will all work.
I would not recommend exporting your single exposures as JPG before stacking, since JPG will loose data and reduce quality of the input to sequator
Great point! Saving in 16/bit TIFF is the way to go, but for space reasons I was just using JPEG for this video.
I'm looking forward to doing some deep space object and Milky Way shoots over the next few weeks. I got the Pentax K1 which has a built in AstroTracer allowing 5 minute exposures of stars without an external tracking device.
My fiance and I both have Pentax Cameras. She has a K-1 and I just got a KP. Both cameras perform amazingly well whit astrotracer. 10/10 can recommend!
I like that you showed people how grainy photos are caused by not enough light rather than a high ISO, but I think a more fair comparison would have been two images at ISO 40,000 and one 15 second shot vs one 60 second shot. It doesn't really exemplify that ISO doesn't matter much for these shooting scenarios when you shoot at ISO 1600 for the long exposure image. Just some minor constructive criticism. But overall, great video, and looking forward to see more!
Don't you need to maintain the EV? If shutter speed changes by 5 stops you would need to change the ISO by 5 stops to maintain the overall EV. If you only change the shutter speed by 5 stops the will be much brighter effectively eliminating the stars and milky way
@@wallytuescher2175 In the video, Peter is making the point that it is shutter speed and aperture, not ISO, that is affecting how noisy a photo is. He's using the desert floor as an example. In the 15-second, ISO 40,000 shot, it's very noisy and has color mottle. In the 60-second, ISO 1600 shot, it's not nearly as noisy. I'm merely suggesting to do both example images, one 15 seconds and one 60 seconds, at the same ISO to highlight that it's not ISO affecting it. In order to make the exposures even, one could raise the 15-second exposure by two stops in LR to match the exposure of the 60-second image.
So, yes, you do need to maintain the EV for a fair comparison, but that's easily done in LR what I'm suggesting
thankyou for making this
Hi Peter, Great video, I have a question on the Star tracker.
The image your taking with the tracker, is it at the same location that your foreground image is taking or do you have to take it at another location with no distraction or subject matter blocking the horizon. something I noticed on the video that you didn't show the star tracking image before you showed it stacked onto the foreground image. Cheers
Listening to Mirror's Edge Catalyst soundtrack in background is refreshing :-) Thank you for your nice tutorial!
Catalyst soundtrack is so relaxing
How much patience you have, well done thanks.
Excellent.
Your advice has really helped my astrophotography a ton. Also, loving the UNATCO (Deus Ex) music towards the end - great stuff.
Great channel. Well explained 👌🏼 What would you say is better. A foreground stacked with a program (several 15 sec) or a longer exposure for the foreground which is then blended with a stacked sky?
Thanks for all the great info. I'm going to attempt my 1st milky way shot this weekend. No tracker or intervalometer and in bortle class 4 on the east coast. Hopefully I can get something to work lol.
Good luck! Keep it simple: relatively short exposure for sharp stars, wide open aperture, high ISO!
@@PeterZelinka thanks for the info. I have the kit 18-55mm lens, 50 mm 1.8 and 28-75mm 2.8. Which does you think I should try 1st? Hopefully I can get a chance to try tonight. It's super cloudy and rainy.
great stuff mate, love your simple practical tutorials 🤘🏼🤘🏼
When you use crop sensor then you need to square the crop factor as what matters is the surface of each pixel. For example if you turn on apsc mode on a FF camera it will be the same squared conversion. Like 42 megapixel a7r3 is 18 megapixel in apsc mode.
Also the rule of 500 400 300 does not account the megapixels. I usually use the following formula: 6000 divided by (megapixels * focal length * crop factor squared).
Waooo amazing!!!
THx for sharing !!!
Interesting and well produced tutorial. One question, where’s the music coming from?
The heavens !!
Hey Peter great video as always! I've learned so much from you over the last year or so. I finally got my star tracker (Skywatcher Star Adventurer pro) and have been having fun with it taking images of things like Orion Nebula and Milky Way. In the future, I'd love to see a short video on balancing those trackers with the heavier tele lenses like 70-200. I feel like when I try and balance my tracker AFTER having to polar align, it moves while attaching the extension arm enough to really impact image at say, 200mm. Not sure if there is a technique or not to keeping things in alignment while having to attach that heavy arm. Anyhow, I had a question for you. When I have used Sequator in the past and even recently I always run into this same problem. I use Lightroom to batch edit like you say before for basic adjustments then I save as TIFFs and reopen in Sequator. When I do this and this is where the problem is, it always changes the color of the image. So, if my LR edit was what I wanted and I take it into Sequator it changes it purple. I was curious if you had any ideas/input as to why it does. Should the output color profile be RGB from LR when I save as TIFF? Does Sequator only recognize one color profile? Should I be converting the original to 8 bit before saving as TIFF? It' a HUGE problem which is why I never use it and go to Photoshop to stack instead even though it's more work. Thanks for all you do as we appreciate it. Great instructionals. Cheers from Florida.
I've never really had that problem, though rarely I will notice a slight color shift. I use sRGB and both 8 bit and 16bit Tiff files, depending on the image. I also don't use Lightroom for the initial edits, maybe that is somehow altering the process slightly.
Hey. Do you have any good solutions how to blend such a foregrounds with a lot of details sticking into the sky? With long exposures they get blurred both sides (because tracker moves with the sky) but in the nature they are smaller ;) that's the only downside I always get troubles with.
Thank you for this Peter. Besides being interested in trying a Milky Way photo, I want to bracket indoor real estate photos (and basically everything!) and merge them. I tried to subscribe to photoshop and Lightroom, but I couldn't get them installed for love or money, so I'm wondering if this software will help me.
Thanks you very much for this video) Hello from Russia)
Recently I just create my first milky way timelapse video shooting with a single smartphone, that's really a enjoyment when done it. I'd like to try this application and stack a single picture.
Thoughts on a wide angle fish eye lens with no AF? Ive always had trouble adjusting focus with no star tracker.
ThisVideo is so informative
I recommend reading the article. True, she is in French. There is a much more accurate formula for calculating exposure. It takes into account pixel size and sensor resolution in general:
"Règle NPF - calcul du temps de pose sans filé d'étoiles"
Photopills have NPF section as well. Click on the cluster of stars icon.
Thanks for the video :) what's the music in the background? It's very relaxing
Stacking allows you to brighten up the pixels, while reducing the noise at the same time. However, in your stack of the milky way, I did not see the image become bright at all, or the details to be more clear, even though it did reduce noise. Any explanation for that?
i just used a gfx 100 to get the milkyway and dude you have to try it !
Not a lot of videos like this explaining the difference between star tracking, stacking, or just single shot without tracker. Pretty well explained too.
The closer you are to the celestial pole with your composition, the longer you can go without trails. The Milky Way is at the celestial equator, which means the 500 rule won't give you sharp stars because of faster apparent stellar motion. If you take some dark frames, that will help but I don't know if Sequator supports it. Starry Landscape Stacker does.
Sequator does support dark frames
Hey Peter, thanks for the video. I am interesting of how you blend your long exposure foreground image and images taken with tracker, since the foreground will be rotating when tracker is on. I can get some OK result with painting mask in sequator but wondering if there is other tips? Thanks!
I cover that process in-depth in my Astro Post Processing Course on my website. We use luminosity masks to quickly create a clean blend, even if there are a lot of trees or bushes.
awesome
Hi Peter, first of all great video!
I noticed that all of the presented images are taken at quite dark locations. But due to the lockdown still going on at the moment in Europe I can't travel far. Does a sky tracker also improve the details in the milky way in more light polluted areas (Yellow areas on dark site finder)? Are light pollution filters, clear sky filters here of any use? Any tips for shooting in those areas? Thanks a lot for your support.
When I'm back in Ohio I live in a yellow zone. The star tracker doesn't really do much for light pollution. But you'll still be able to get a cleaner image.
Light pollution filters can help, but often they don't do that much (especially at a wide angle). Although it depends what filter you use.
@@PeterZelinka Thanks a lot for the reply 👍
For light pollution correction, I will first slightly shift the colour temp towards the blue side as Peter demonstrated in the LR's Develop Module or in Adobe Camera RAW in PS, then follow that up inside Photoshop CS-6, using the Colour Balance adjustment (Image->Adjustments->Colour Balance). I click on the box Preserve Luminosity, select Midtones, then shift the first slider towards Cyan to -9, the second slider towards Magenta to -3, to remove some of the green cast, and then the third slider towards the Blue to +24, to remove the yellow cast. I repeat for the shadows.
Note that I vary these settings depending upon the shoot location, and if my camera is facing towards a distant city, or north, where I have relatively low light light pollution. This tool will remember the last setting used, so if you have a lot of similar images, just click OK and continue on. You can also automate this using Photoshop's Automator (File->Scripts->Image Processor) if you have tens or a couple hundred images to apply it to.
Here's a sample image of Comet Neowise from my IG page, taken in the countryside in Lancaster, Ontario (just outside a yellow zone) about 90 km/55 miles west of Montreal (metro population 4 million) where I applied some NR. instagram.com/p/CC6HBOHn8_E/
Hope this helps!

Great vid! What kind of lens are you using? :)
Can someone tell me the BEST astrophotography lens that can mount a Canon like Canon T8i or Canon 90D? I heard of IRIX 15mm f/2.4 as well as Rokinon? Any suggestion of the BEST lens that is amazing in all aspects that can take nice shots of the Milky Way as well as Orion Nebula?
Great Video Peter! Qq: for the Utah shot, how did you blend the foreground so cleanly on a 4 minute exposed sky? Didnt the blur of that rock jutting into the sky region leave dark blurry blobs after you replaced it with a non tracked FG?
That will happen if you take both photos in the same place, which I don't recommend. I usually move the tripod to a nearby spot without any big foreground elements in the frame and shoot my tracked image
I've been testing photo stacking with the comet. If I stack 150 pics, I get really good results. But, if I stack 300, it's amazing. I wouldn't recommend stopping at 20 pics. Take as many as you can possibly get. The more pics you stack, the better the signal to noise ratio will become, giving you a cleaner, more detailed final image.
Thanks for the info, just one small question... Do you use any self rotating tripod, or do you follow it manually or even take the same angle shots ?
@@mariokladaric4746 The camera is on a tripod. That's it. No tracking or anything like that. Then I use a remote control to operate the shutter. If I know the comet is going to move from left to right across the sky, I'll have it start more on the left side of the field of view, and let it move across as I'm taking all the pics.
Doing it this way means you can't use much more than a 70mm lens. You need to leave the shutter open for about 4-5 seconds to get enough light in, and being zoomed in too much will result in star trails.
i will try this for my Samsung phone, I'm sure it works fine.
Love the Noveria soundtrack from Mass Effect.
Well with these settings my camera doesn't take any pictures I'm using canon m50 with kit lense 15-45mm
With gathering more light with longer shutter speeds using a star tracker, do you get more color in the stars and gases than when stacking 10-20 shorter shutter images?
Since I have Pentax cameras I ordered the astro tracker GPS unit for $160.00 it can give me a 5 minute exposure for little money by tracking the night sky with the in body Stabilization unit on the camera the cameras come with the software built in it will also stack in camera also if I do multiple exposures
So if you use a sky tracker/guider, it is going to cause the foreground to rotate as well in the images. How do you account for that? Will stacking software automatically adjust it? In the case with Sequator, freeze ground I assume?
Thanks for the video Peter. I believe Sequator is pronounced " see' qway tor" like equator with an "s" in front. I've used the program myself with good results. Good tips!
You're probably right haha
Who cares
Peter, this would have been more accurately illustrated if you did not change the ISO, only the Shutter Speed (Time). Of course, you would have gotten a "Cleaner" image using a Lower ISO setting as you did. But leaving the ISO at 40,000 and increasing the Time or Shutter Speed would have better illustrated a Cleaner Image with the Additional Light. Also, a good trick to help minimize noise at Higher ISO settings is to Over Expose you Image about a Stop, and when you process it you have to now make it Darker, thereby Compressing the Exposure which helps make the Noise less noticeable. When an Image is Under Exposed, and you Lighten it in processing, you are Expanding the Exposure, thus making the Noise more noticeable.
Can I do photo stacking on a chromebook
2020 vibes
Sir may I ask a question, nikon z6 samyang 14mm is it a good combination for the Milky Way
If u take the AF one, there is a Focus issue in dark light so it is not recommended. If u take manual focus one, u wont be able to put filters on it. Thats the dilemma
Great review of stacking vs tracking. quick question, is there a method to polar align if you can't see polaris? I use PS Align Pro for my Sky Watcher Star Adventurer but if I am in the canyons i can't always see the north star. if I use a wide angle lens, can I "wing" and try to get close enough and maybe only track for 1 min vs 4 min?
Sunny Hwang You don’t need to be super accurate while using such a wide lens. If you can get the North Star anywhere into the circle on the polar scope it will be good enough.
As Kyle mentioned below, you don't have to be that precise when shooting ~14mm. In the past, I would just aim the star tracker North, try to get the North Star centered over the top, verify the latitude was correct on the base, and begin shooting.
However, I always had the north star visible for this rough alignment. If you are down in a canyon, you'd be in for a much more difficult challenge. Then again, if you are only going for a 60 second exposure, you could probably pull it off!
Nice tricks
Wait, so you said (in your opinion I'll assume) that photo stacking is cleaner than using a star tracker but you use the star tracker still? Is stacking so clean that the final results look over produced? Also, I have never understood the point of stacking more than 5 images unless you are not only stacking for light values but focus as well in the case you have a subject closer to you that can't be achieved in focus when focusing at Infiniti for the sky. Another time when shooting skyscrapers I needed a 3rd value focus for the name of the skyscrapers because the letters were not clean during long exposure they were blown out. Thanks for your time doing these videos, I'll check out some of your other videos.
Do you change the exposure by changing the ISO? Or do you change your shutter time?
weird I have to use 1 sec exposure to avoid startrails on 34mm cropsencor camera.
But you do 20 seconds?
Btw I had to use 400 shot 1 sec picture to get a decent image
I personally love the star trails
Would the result be different if I stack the images before the editing, or should I rather stack the images after the adjustments in Lightroom? I always stack the images before doing any adjustments.
If the WB is off on one of the images it might fuck up your colors. E.g. your last 4 shots were at astronomical twilight where the sky changes color
Always do:
1.step: images acquisition
2.step: images calibration
3.step: images stacking and normalization
4.step: image final editing and sharpening, Lightroom fiddling, exporting for the web.
If you had everything manually set in-camera, you could stack your RAW photos. A lot of people online recommend stacking RAW images too. Personally, I think that's a bad idea (at least for Milky Way photography).
If you stack the RAW data, then no color noise reduction will be applied. In my experience, this will become a major problem after the stack.
You should get much better results if you do your basic edits in Lightroom first. This would allow you to fix any vignette, chromatic aberration, white balance inconsistencies, exposure problems, etc... Lightroom should also apply the color noise correction automatically to every photo. Then you can save the RAWs as 16/bit TIFF files. Finally, stack those TIFFs in Sequator or StarryLandscapeStacker.
I'd recommend trying both approaches on the same set of images (stack the RAWs, and stack the edited TIFFs), so you can see the difference in the final stacked images.
@@PeterZelinka
Ok thanks for the response. I definitely have to try both methods.
Can you do this on a entry level camera like d5600? Do you already have similar video?
yes you can
What about light painting?
The most important Part is missing: Plan and scout for an interesting compositions. 😉
The other stuff is important, too, though.
Sequator doesn't seem to work for me... It either looks the same as a single frame, or it "stacks" them with the accuracy of a toddler. Meaning it doesn't align the stars at all. Dunno, considering it is a pretty simple program, I don't think I'm doing anything wrong. I do like the freeze ground feature... if it stacked the stars for me. Gotta try Pixinsight and see if it has a similar function.
