    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.

    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.

    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 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.

    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'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).

  • @selkieboat
    @selkieboat 4 года назад

    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?

    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!

    • @PeterZelinka

    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.

    • @PeterZelinka
      @PeterZelinka  4 года назад +1

      I would say there is a noticeable difference. Stacking short exposures is a good first step, but a star tracker will take things to a new level.
      You'll be able to pull out a lot more fine detail and color once you start shooting 2+ minute exposures. You could even stack multiple longer exposures together, but usually a single image is good enough.
      The only real downside of using a star tracker, and taking longer exposures, is hot pixels. They tend to blend in with the stars, but I still find them to be a pain. There are ways to fix them, but I'm still trying a few different techniques to determine the best option

  • @jimabels9075
    @jimabels9075 5 лет назад

    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?

    • @PeterZelinka
      @PeterZelinka  5 лет назад +1

      I normally prefer using a star tracker. There are a few drawbacks though. Since I normally take a 4 minute exposure, I have a ton of hot pixels. Therefore, I used Long Exposure Noise Reduction, which effectively increases the total exposure time to 8 minutes. That's a long time to spend on a single photo.
      I've gotten much better images overall when using a star tracker. Photo stacking isa good way to reduce grain, but it has its limits.

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

    • @PeterZelinka
      @PeterZelinka  5 лет назад +2

      I personally edit all of my RAW files, including the dark frames, and save them as TIFFs first. Then I drop those into sequator.
      The dark frames should have the same edits applied as the normal photos.
      Editing the RAW files first helps to reduce the color noise and vignette, among other things.
      I know many other people would argue that you should only use RAW photos and not do any editing before stacking, but I disagree.

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

    • @PeterZelinka
      @PeterZelinka  6 лет назад +1

      Good question!
      I actually don't have many stacked images with trees in them, but I did find one example to test.
      It worked surprisingly well. There were a few artifacts around the trees, which looked like black star trails. Besides those minor streaks of black, everything else looked really good!
      If you have a really complicated scene with trees, I think Sequator would have some problems. However, I do have a post-processing tutorial for blending complicated scenes like that in Photoshop. You can watch that video here:

    • @PeterZelinka
      @PeterZelinka  4 года назад +1

      It really depends on your camera. Most people online recommend stacking your RAW photos, then taking that stacked image into Photoshop. This is a good idea if you also have dark frames and flat frames.
      However, I do things differently. I normally edit my RAW photos first. I want to fix the overall Exposure, White Balance, apply lens profile corrections, and any other small adjustments. Then I sync those changes with all of the photos. I save them as 16bit Tiff files next. Finally, I use Sequator to stack those Tiff files.
      I'd recommend trying both approaches and see what works better for you.

Tightening the clutch after polar alignment with Polemaster may solve the balance problem with long telephotos still within the weight limits of the mount.

    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"

    • @PeterZelinka
      @PeterZelinka  4 года назад

      Tiff and Tif are the same thing. It sounds like the files may have gotten corrupted or something. I'd try redoing the process

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

  • @dkgarcticboy

    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?

    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.

    • @Dan84043
      @Dan84043 4 года назад

      Sequator is useful for stacking separately the sky and the foreground. Siril can't do that, however gives much better results for "pure" astro shots, i.e. without any foreground.

    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?

    • @michelfries8307
      @michelfries8307 4 года назад

      CelebrityLyrics I have no particular experience yet bu I'd say that a fast lense 2.8 and below are just nice! Rokinon is well known in this area because of their performance/price ratio. But Nikon, Canon, Tamron, Sigma lenses are all fine!

      2 years old but if you or anyone else sees this, it's a similar process where instead of taking many exposures and stacking them, you actually record a video and use a program to stack all those hundreds/thousands of frames, AutoStakkert

    • @HansensUniverseT-A
      @HansensUniverseT-A 6 лет назад +1

      @@PeterZelinka It's honestly really good, Sequator is probably better if you got a foreground but DSS does a pretty good job at handling big files and lots of it, I've tested with 69 exposures, almost 4 hours of integration time with drizzle, i guess the memory issue is resolved.

    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?

    • @michelfries8307
      @michelfries8307 4 года назад

      Dazza dizzy For the light frames, put a t-shirt on top of your lens and apply a light source like your smartphone or tablet on top. Take 10-15 shots with same ISO setting and speed as your sky pictures. This will reduce/eliminate the vignetting on your final photo.

    Hey Peter, Could I get your thoughts please? I have just stacked 6 images and clicked open and it just seems to run forever, should it open directly in PS? I can see the stacked file in the folder but from within Sequator it doesn't open....CHeers

    • @PeterZelinka
      @PeterZelinka  6 лет назад +1

      Hmmm, that's odd. I'm really not sure why it wouldn't open the TIFF into Photoshop. There's a ton of variables that might be causing that. If I had to guess, here are a few: Default program set to open TIFF files, random software bug, Photoshop version incompatibility, etc...
      I would simply navigate to the folder where you saved the TIFF file and either right click to 'Open With - Photoshop' or open the TIFF once you've started Photoshop. Either way should work fine and allow you to continue with the workflow

    '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?

  • @loschekell

    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.
