Orion Nebula With A 75-300mm Lens Processing

- In this video I process an image of the Orion Nebula taken with a 75-300mm kit lens. I'll talk about to to stack in Siril as well as Deep Sky Stacker. I'll then use Siril for some basic processing before switching to Photoshop for the rest.

So here I am watching a video on a program I’ve never used because you’re such a good host Walt.
Same but he will never get me using Siril 🤣
You're doing great job. I love your processing videos. I wish to see them more frequently
Thank you! Photoshop or Pixinsight or both?
@@deltaastrophotography I've just started my astrophotography journey so I prefer less compex tools such a Siril or Photoshop. One more time thanks for your effort
I’ve only been doing Astrophotography for a year but your tutorials have been a game changer for me. Thank you so much for what you do and keep up the good work..clear skies
Spectacular tutorial! Thanks for all the tips!
Fantastic tips on getting to grips with nebulae
I've got all of the equipment and I've got all of the software. Now when I get my images and calibration frames, this is the tutorial I am going to use to stack and process them. I have been watching you for a long time and you have come a long way. Keep it up. You are an excellent teacher.
Last week i collected the Orion Nebula data and did a basic process. This tutorial will be my next 'real' process.... can't wait! Thanks for this!
Glad you are well! I saw the tornado hit Mississippi and was hoping it wasn’t near you.
Walt, another insane video. Thank you so much for all you do. This was super duper helpful. God bless you.
Another great video there Walt. You have an excellent way of providing easy to understand steps but making it fun too. Keep up the good work 👍👍
great video! I can't wait to try this.
Thanks so much for this. Supremely helpful. Keep up the great work 👍👍👍
Took a bunch of notes! Thanks, man!
I don't do astrophotography and will never take a photo of the Orion nebula but I watched this from start to finish and loved it.
Great tutorial. I have been using SiriL, Lightroom and various other programs to process my astro photos. Very new to photoshop. Worked through this workflow in photoshop and the final image came out great.
Nice work Walt!
Yess another video of my favourite astrophoto youtuber 👍🏼
Thanks man. Great tutorial. ❤
Thank you for your amazing work, Walt. You inspired me to photograph the Milky Way. Last year didn´t go well, I´m looking forward to accomplish it this year.
Great tutorial Walt thanks for showing us Siril, it looks like a nice piece of free software
You have produced a beautiful image using everyday equipment.
Waayyyy better than my previous edit. This was great!
Loved it
Perfect timing for me to do some work on my images from the other night. I am having issues getting StarXTerminator and StarNet to run on my computer. I’ll be digging in to see what the issue is and try to fix it. As always, enjoying the videos at the entry level because it makes sense to me right now.
Wow... Your final image looks much more detailed and I like the brown dust... You should do a video of start to finish on the images that you "spend more time" on, to show which parts you spend more time on.
I know! I don't want to make a 2-hour video on processing. But basically I just keep stretching while the image is starless until I get it just right. That takes a while! In Pixinsight it takes only a few minutes.
Nice workflow Walt. I've noticed with star exterminator it sometimes leaves a grid pattern when stretching the starless image. By selecting large tile overlap it seems to fix those artefacts but increases processing time.
Awesome good tutorial!!!
Great info walt, just updated Siril to the new version that allows starlet V2 to run, and updated paint shop pro.. thanks for the guide
Awesome!!!!
Brilliant Walt thanks very much, I only use unmodified dslr so if possible more of this kind of thing,and more unmodified images. Again thanks for very useful information.
Outstanding video !!!! Question: I have seen some Orion Nebula photos where a red arc of gases is in the pic, will post process be the same?
Yo, do a mineral moon next! 🤜🤛
I will follow this processing this Weekend. My only question if you can help me is: I did three sessions for the Orion. three different nights but with same settings on the camera. I took Darks, Flats, Bias, too in all nights. How should I deal with DeepSkyStacker? Do each night separately or all nights in one go? If I do them separately I will end up with 3 stacked photos. Should I stack them together? Thanks
Great tutorial video as always! May be the wrong area to ask this question, not sure. I've seen where a lot of people say they're adding new photos to existing data to improve the image. My questions are:
1. Do they use the existing data as 1 photo and add each individual new photo, or stack the new data then combine it with the 1st data set as 2 images and reprocess?
2. Would the camera settings need to be the same on each data set such as ISO, exp time, etc?
I've been meaning to make a video on this. In Deep Sky Stacker once you've loaded all your frames from night one, you then see an option at the bottom next to Main Group called Group 1. Click that tab and add all of your images from night two. You can repeat this process for as many nights as you want. And yes all the camera settings have to be the exact same.
Hey Walt. Last question, I promise...lol. So the plugins from RC Astro that you use, how much are each, how do you install them on PS, and how much memory should you have for everything to run smoothly? I'm already getting a "No DirectX" and "No VRAM" whenever I open PS.
Hey walt. In Siril, when you are stacking, you said that you need the script that is without whichever calibration frames you dont have. But none of them specifically have "without bias". Does Siril not care whether you have bias frames or not?
What is the difference between levels and curves? I thought they were just different ways of doing the same thing, so why would you use one over the other?
@Delta Astrophotography What PC do you use for your processing?
I bought a gaming PC not too long ago. I don't remember the specs off the top of my head. Nice graphics card, AMD Ryzen CPU, and 32Gb of ram.
Hii pls reply sir I have taken 1010 photos of Orion Nebula total exposure time 33 minutes I forget to take my white t shirt and not able to take flat frames but have taken dark frames and bias frames will this affect my image quality and what to do now is there any solution for that iam confused pls reply sir
Hey Walt...im currently running in Siril, but i get red messages saying "Bayer pattern found in header (GBRG) different from Bayer Pattern found in setttings (RGGB). Overriding settings." What is that??
Hey Walt. In Siril, which script would you run if you had bias frames, but no darks or flats? Or what if you had darks and biases frames?
This is a tricky question and a lot of people have opinions. But if you just have darks then you don't need bias. Bias is mainly used to calibrate flats.
@@deltaastrophotography oh ok... So, in my case, my images have horrible hot pixels that show up as blue and red dots... Which calibration frames would remove those?
@@kevinashley478 Darks should take care of that.
Is it possible to image the Orion Nebula without blowing out the core, using the 75-300mm lens?
Not really. A lot of people take a serious of five second exposures to keep the core intact and blend that in with the longer exposures. That's what I usually do actually.
Is this your own music in the background Walt?
Sadly it's not. But it has given me some inspiration for what kind of music I'm going to eventually compose for this channel. Making a video is kind of hard for me right now because I'm still learning. But as it gets easier I feel like I'll have more time to work on my own music as well.
I have heard multiple people say that Photoshop does better with 16-bit than it does with 32-bit. Why? What's the difference? What about 32-bit is hard for Photoshop? I would think the 32-bit would be better image quality. Could you explain the difference between the two and why the preference for 16-bit?
32-bit does contain more detail. But a lot of the basic Photoshop functions don't work with a 32-bit file. This is a big reason why Pixinsight is much better.
@@deltaastrophotography so pixinsight works with a 32-bit file?
@@kevinashley478 Yes!
@@deltaastrophotography but which software is better at processing the images?
@@kevinashley478 Overall PixInsight is better because it's very specifically designed for astrophotography. Photoshop still shines though when it comes to things like fixing a blown-out core or selectively enhancing certain areas of your image. If Pixinsight added layer masks then I would never use Photoshop again.
