You should do all the instructional videos on the Internet, you have a such a pleasant voice! Many thanks!

This is so easy to use! I came up with a nice picture before I even finish the video.

Thanks Peter for taking your valuable time and sharing it with others. I worked for NASA running the MOTS (MiniTrack Optical Tracking System) at Orroral Valley in Australia. Out spacecraft shots were captured on Kodak F103 10" x 8" Glass plates, Our camera/systems cost would bankrupt small Nations. I mainly use Nikon today, Hasselblad and Linholf rail systems, .. display only now. Time to down-load Sequator.... Thanks again Peter.

Just downloaded it and used it. Absolutely brilliant program, especially for wide field lens shots. Many thanks.

I use sequator since 1 year but i found your tutorial very interesting as a good refresh about how to manage or the difference characteristics. Thanks

Very good video. FYI Pete mentioned using more than 10 pictures not being worth it. I happily disagree with Pete and followed what the deep sky guys do. This weekend I took and stacked 8 minutes worth of 6 second photos with my Nikon D3200 with a 35mm at f1.8 ISO400 and had INCREDIBLE results! I wish I could share a picture here. I turned on most of the settings - Auto Brightness, High Dynamic Range, Remove Dynamic Noise, Reduce Light Pollution. Very little post editing needed. The 24mm @f2.8 ISO400 and 18-70mm @ f3.5 ISO 400 also looked pretty good but not as much detail. I am trying to stitch together a a 6 picture pano of the 35mm to get more sky but am having trouble with differences in the color of the sky from picture to picture.

I've been looking for a Windows program that will do what Starry Landscape Stacker (Mac only) does, and this is probably better. You did a great job on the tutorial - it really helped me get started. I do have a few suggested workflow changes and a few comments: * you can do this in Photoshop using layers, smart objects, and the mean or median blend mode. It takes a lot more time that this does, but it is possible (I have not had issues with align layers working) * I'd suggest doing a dark frame at the start and end of the sequence, as the hot pixels are related to the heat developed in the sensor * LR and ACR do have lens profiles for the Rokinon 14mm f/2.8, which is what I assume you're using - you have to manually select the lens (manufacturer, model) and do this on the RAW file (not a TIFF) * I found that Sequator's results were much better when I did (almost) all the edits in post. I apply lens corrections only in LR and export the files as DNGs. The Rokinon 14mm is a fantastic lens for the money, but it does have a lot of barrel distortion. * the light pollution filtering works really well. I had the best results with uneven/100% strength/intelligently-aggressive set * Sequator does a good job of noise reduction (far better than reducing the noise in a single image) but the output files still need some noise reduction (I used Nik Dfine2). The light pollution removal (I think) also added a purplish line on the horizon which was easily removed with a manual chromatic aberration adjustment in LR. * rather than setting all the options from scratch each time, save the project. For a new set, open the project (.sep file), replace the base frame and star images, and re-mask the sky Thanks again for putting this together.

Agree, I have used sequator for a while for astro-landscapes and DSOs.

Thanks for the excellent tutorial, Peter. Just new to Sequator and you've saved me a ton of time.

i was looking around for rookie friendly AP programs and i found your channel , and since i am a rookie and you explained this so well that i even understood , i subscribed ,thanks a bunch

I use Sequator all the time. This has been a good refresher.

Peter, your demonstration of this software is spot-on. Great job of explaining.

I van recommend to use Sequator with different light Pollution filters and autobrighyness on/of, getting different results and put them afterwards together with a HDR program to get more output from dark regions - especially from a dark foreground. A mice feature in Sequator is the time lapses function to put let's say 5 images together and go through all images. So it is possible to get more dynamic in your time lapse.

Thanks for your great video. Sequator worked perfectly well to render my milky way shoot at 14mm while Photoshop failed completely. I really appreciate your tutorials. Cheers.

Awesome vid. Just bought a Samyang 16mm f/2.0 for shooting the milky way. This tutorial is excellent and this software seems way less overwhelming than photoshop. Thanks, bro!

Thanks for sharing the great tool. The developer is a Taiwanese by the way.

Best instructional on Sequator! Awesome job Peter

I've been bouncing between Sequator and DSS, and always seem to be drawn back to Sequator. DSS does allow use of dark bias frames, but frankly, at my current skill level, I haven't noticed any improvement. Sequator is sooo unknown/underrated. Do the creator a favor and buy him a 'cup of coffee' (Paypal link on his website sites.google.com/site/sequatorglobal/encourage).

That was very helpful. Hadn't heard of Sequator yet and hated the workarounds needed in DeepSkyStacker to get large files to work. Thanks!

Never heard of this program. Thanks I can't wait to try it out

Subscribed to your channel! I have been binging on the content! I have a few good shots of the Milky Way w/o using a tracker, and now that I have a tracker I am ready to take the next exciting steps :) Keep up the great work

thanks for letting me know about this program. It‘s pretty good. I tried it. I needed an alternative because I recently encountered problems with deep sky stacker where it wouldn‘t stack all of my light frames, only half of them. They where shot at different nights and I tried many times with different file group tabs an so on,but nothing worked. And sequator seems to stack eyerthing, no problem at all.

great tutorial I was looking for tutorial in how to do stacking with GIMP. I am very glad I found your tutorial. Can't wait to go home and play, thanks.

Great little tutorial, looking forward to getting stuck into your other vids. Subbed ✌️

Thanks for the info I downloaded it solved all my stacking computer issues

Great walkthrough, Peter!

Very nice presentation. Thanks for the tips!

In a nutshell -- is there a huge difference in results between using a stacking program vs shooting long exposures with a tracker. Thanks for these great videos -- I'll keep watching.

thanks so much, can't wait to give this program a try

Sequator did a better job when I used my tamron lens for DSOs but now that I use the Redcat 51 Telescope, Deep Sky Stacker does the better job.

I am just starting in astrophotography and need to know if you are using Sequator as a Photoshop plug-in? I have had my Ioptron Star Track Pro for a few years and just now am getting around to using it because your tutorials are great and easy to understand.

The author is from Taiwan, not China. :) Kudos for him on his work on Sequator.

Beautiful and helpful tutorial. Thank you

ARE YOU SERIOUSS your base image is my own life goal on Milky Way lol Where did you shoot that? Altitude, distance from abitations etc etc

Much faster than DSS. Also has light pollution correction. Have used both on DSO and milkyway and SEQ was better in both cases.

Awesome. Can't wait to try it out

Thanks Peter for the video. I would pronounce the program name like "equator" with an "s" in front. "See-quay-tor"

I watched this video and immediately decided to download and try it. Unfortunately, it's a Windows-only application. sigh... back to DSS. ugh.

I try to use it with the latest 4.x WINE on Apple and it seems so fast and promising....BUT CRASHES AT THE END OF PROCESSING THE LAST IMAGE. Wish there was a Mac addict who would make a WINE bottle of this...

Well, I guess I know what I'll be testing out tomorrow 👍. DSS really is a pain to use and takes away all of the nice colours, and Photoshop...eugh, I have to do so much processing just to get my images (maybe) looking good enough to stack.

Cool👍🏼 Thanks Pete!

Great tutorial mate!

thanks for the great video!

Great tutorial. Thanks, Man!

Peter...Thank you for all the amazing and informative videos. I am just getting started with shooting the night sky and have been taking a ton of notes from a lot of your videos. For now I am just going to be doing milky way with the rokinon 14 mm f2.8 on my Nikon d5600 and also using the skyguider pro you recommended in one of your videos. I had a question when it comes to stacking, besides the "lights" and "darks" which i think you mentioned can be done anywhere and anytime, when it comes to actually taking the pics of the foreground I assume the 2-4 minute exposure is with the skyguider not rotating...and then after that shot turn on the rotation for the milky way? When it comes to taking the pics of the milky way, once you find the right shutter speed (between 2-4 minutes) do you take lots of pics at that sweet spot and then stack them, or do you vary the time from pic to pic and then stack them? Lastly, with the camera on the skyguider is it possible to reduce the iso down to 400, or for night sky shots is it always best to shoot at iso 800 and above? Sorry for all the questions, Im just trying to make sure I am covering the main topics as I am planning on going to Cheery Springs State Park either Wed Aug 28th or 29th to shoot the milky way.

I am so confused about one thing when using Sequator. I take my star photos in RAW, open them in "PhotoDirector 10" do exactly what you suggest, then export the files to a folder as TIFF. I then proceed to open Sequator, and add the TIFF star images. I then get a message in the main screen "read failed! Unsupported format or invalid path. But at the sametime in the work box to the left, I can see all my TIFF files under Star Images with a green light. And the middle Base image purple. Now if I do the exact same thing, but using RAW to import it works! I am told that it is better to use TIFF than RAW. I didn't even think Sequator would read RAW?

Definitely better than DSS and a hell of a lot faster!

Awesome tutorial. Can you please tell me how did you got rid of that tint with curves layer?

Very good job. Thank you.

Hey man !! Amazing tutorial ! thanks for sharing !! I was wondering if you were using a tracker aswell ?

Hi Peter - great tutorial! Thanks. Can you use it for the comet Neowise?

Thank You very Much Dear Master

Looks worth a try. Thanks for the great tutorial on it. What lens did you use for the Deep Space Orion photos?

Hi, great tutorial. One question, can this programme be used for other photo stacking subjects such as macro, or is it just for astrophotography.

Hi, Peter - thank You for a good tutorial. One question for the Orion nebula - which lens/ focal length did you use for those photos? Thank`s in advance. Stein

Thanks! Today I've opened this beautiful soft to mysels at last. )))

DSS seems to have a deeper limiting magnitude --- you can see fainter stars, but it's subtle. As he said, Sequator is more grainy which would tend to drop out very faint stars. Yet both are good.

Just a quick question: Do you post-process the dark frames aswell? Or do you just put the raws in Sequator?

Hey Peter, I wondered if you'd tried this program with trees or objects in the foreground and how it works around those ...??

Awesome information Peter!!! What focal length did you use for Orion photos?

Thank you. You convinced me. ;)

Great video man! Regarding techniques to map your lens's vignetting....is there a difference in quality between the 2 methods you mentioned (Lightroom/Photoshop post-processing vs. photography a bright white frame)? The reason I ask, is that I have seen slight compromises in corner sharpness (i.e. the parts that were vignetted) when using the Lightroom method. Was just wondering if it would be worth the extra time and effort to do it the other way instead. Thanks!

Should be noted that 1. This software is only for non-commercial use

I see a light source in your pic and yet still the milky way is clear before even to stack. What dose it take to have clear milky way with a light pollution.

appears to work when running under LINUX MINT 19.3 with WINE.

Now that DSS is 64 bit i run DSS over this anyday.

For wide field nightscape, do you prefer to stack or bring the tracker for 1 long exposure instead. Does this make the tracker less useful and more for just deepsky photos. Which has better quality?

If it took FITS files, Sequator would be even better. I use Sequator for my Milky Way shots taken with my Nikon, but my DSO shots (sometimes numbering in the 100’s for each target) captured with my dedicated Astro camera are FITS files. Anybody know a way to batch convert numerous FITS files to TIF files?

Is it tiff or tif? Coz i just converted my RAF files to Tiff and now i get an error message "read failed. unsupported format or invalid path"

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?

Any idea why the Sequator screen goes black when I try to paint the sky to freeze the ground? I'm using ON1 Raw 2020 to export my images to Tiff. I'm using the latest version but also got the same results with an older version.

So all you do to stack is take more than one picture? Or do those pictures have to be different exposures?

Question is how does it work when you dont have a tracker and end up having to take a bunch of 1 sec photos?

How do you balance a telephoto lens on a mount like the SkyGuider or Star Adventurer when they extend perpendicular to the counter-weight axis?

What was the focal length for the orion shot, on crop or full frame? Thanks

'DSS always stops, running out of memory' - really? Mine never has even processing 500+ 16mb subs with darks, flats, and dark flats. Takes maybe 5 minutes. Maybe your machine needs more memory?

Hi Peter,thanks for the test.i did some test too. there are two problems. 1:the stacked image is always darker than the originals.short of dark side and white side according to histagram. 2:if there is a bright thing moving on foreground e.g. a car,we we will see a black stripe on stacked image,in that case we still need photoshop to mask it. did you test Registar? TKS

I am getting a series of composition fails while stacking. Can you tell why it is happening?

If I use boundary line in the Sky region, it's always red. Anyone knows how to fix it?

When i go to download the Microsoft Visual C++ it says my computer already has another version thats installed. So i tried to download the program and it wont run it? Any ideas...

Hi, thank you for the tut! I tried Sequator in the past and never felt happy with the results, so I gave it another try now and its the same experience. It does not seem to matter which selection of settings I choose I end up with a much duller and lower exposed looking image compare to view one of the images making up up the stack in camera raw. Am I missing or doing something wrong or is that the way its suppose to be?

just used my first star tracker tonight, 10 x 4min exposures of the night sky. Should I edit each individually to bring out all the detail then stack or should i stack then bring out all the detail?

Can this be use for deep sky objects, without landscape ?

Do you use Sequator to merge a long exposure foreground shot with ,say, 10 sky shots? Or do you just process stack the star shots in Sequator and then combine them with the foreground shot in LR or PS? Thanks

Do you need anything to install, I tried they wanted me down Microsoft program but my computer said I couldn’t do it because I have a later version, can you get override this or will the new version work

Do you have to use a tracker for this program to work?

I've used this program twice now and both times the image was very dark. Not sure I'm a big fan of this.

Hey Peter, a qns pls: I notice random blotches of green in the background of the sky, which also appeared in all my milk way photos. any idea what is that and how to get rid of it?

do you think this will work on photos of the moon

i can't seem to select all my files at once this is really annoying

When you export your RAW as TIF, do you export as 16 bit or 32 bit float?

When I try it I get "too few stars CANCELLED" any ideas?

Is it useful for stacking macro shots?

Hi, can I use Sequator to export/import to On1 2020?

I try stacking images even just 3 or 4 and just end up with a white over exposed "fog" , is that artificial light just stacking up?

I just found this video and it’s great. I’m still learning and finding my feet. How does this compare to Siril? I’ve been using that to stack plus I find it’s great at post processing also.

Wow..

How many exposures to start with? I'm guessing you edit one raw, apply those same edits to all the raws, export to tiff and then import?

Whats the minimum requirement on PC for this software? Thanks fot Sharing!

Hey, is the orion shot tracked/what focal length did you use on that?
