    You do NOT want to align on the moon -- it's moving, and fast, typically a pixel every 2 seconds, relative to the corona and sun. You must align on prominences or the corona for best results

    • @Naztronomy
      @Naztronomy  5 місяців тому

      I just recorded a video doing the Pellett Method using 2024 data. I align on the prominences and I talk a little bit about the challenges you'd face aligning on them on longer exposures. End result looks great! I should have that video edited and uploaded soon.

  • @dhmccauley
    @dhmccauley 5 місяців тому +1

    Aligning this way doesnt help with detail of the corona. For that you want to align using the prominences, not the moon, so the corona is aligned in all images. Of course youll have to use only one sun / moon image.

    I believe that eclipse photos showing the moon's surface features seem to have an added layer, achieved by adjusting its transparency. I don't believe that they even mentioned achieving this with too many cameras or photo stacking. Yet no space agency or observatory has managed to achieve these views after all these hundreds of eclipses. Suddenly, we have eclipse photos with visible moon surfaces.

    • @Naztronomy
      @Naztronomy  5 місяців тому +1

      Earthshine photos has existed for a while during totality and during crescent/quarter phases of the moon.
      If I understand you correctly, then yes, there are a lot of composites where they add the moon in post processing and then make it transparent.

  • @aaronden
    @aaronden 5 місяців тому +1

    Thanks for the vid. For totality I have 6 different brackets each containing 12 shutter speeds (1/500 to 4”). What is the best approach for maximizing detail? Align and stack all 6 1/500s shots, all 6 1/250s shots, etc., and then use those 12 groups to create an image? Or better to make 6 different HDR images from each bracket and then stack those???

    • @Naztronomy
      @Naztronomy  5 місяців тому

      Good question!
      You may find it somewhat difficult to align your brackets that are taken more than 30 seconds apart because the moon moves across the sun so it'll be at a different position in your first bracket than it is in your last. But it could be worth a try because you could get a good amount on detail on the corona itself, just need to do the aligning part pretty carefully.
      You'll have the same alignment issue if you do the 6 brackets separately and then try to stack them. Again, you'll probably get good detail from the corona but aligning will be difficult.
      If you have time, you could try it out. The latter method (do 6 different HDR images then stack them) may be easier because you can do 2 of them and see how it works.
      I'll be uploading an updated video with 2024 data soon. I show how I double stack this method to get even better detail.

  • @paulmanhart4481

    Interesting method. HDR is typically a weight sum average of each image. You divide each pixel by its exposure and then divide by the sum of all exposures. Your method seems to be a new one.
    I’ve been trying to get a HDR solar eclipse photo since 2017. First time my camera was out of focus (ring slipped). It was a Nikon F/2.5 400 mm lens.
    In 2024, I was ready with a Nikon mirrorless Z6ii and a 400 mm lens, plus an equatorial drive on sun track. But the clouds in Southern Texas screwed me over. I bracketed from 1/3200th to 4 seconds shooting in RAW.
    At NASA, I wrote a MATLAB program that registers digital images to 1/100th of a pixel. I was going to use that to align all the images and then go into my HDR software in MATLAB. The best laid plans of mice and men. I’m seriously bummed out.
    Good job Master.

    @Naztronomy - I know you were doing an abbreviated method here. To do the full method would you blur and subtract then multiply each layer individually then load all the result images into a smart objects mean stack and then adjust and finish? Or is there a way to do that to the individual layers in the original smart object stack made from the aligned layers? I have 10 sets of corona brackets that turned out pretty nice and I'm trying to come up with the procedure to process them all. Thanks! - EDIT - reading down below I think I found the answer to my question. Thanks again! I ran 2 automated rigs and just trying to get the best processing for the amount of effort that was involved.

    • @Naztronomy
      @Naztronomy  5 місяців тому

      Glad you found the answer but I'll write my response any way in case someone else reading this in the future as a similar question:
      You are correct about doing the blue/subtract/multiply on each layer individually and then loading them and then stacking them. This is probably the cleanest way to do it but longer.
      Otherwise, you can load them all as layers and before converting to smart object, you can work on each layer individually but this may be challenging if you have a lot of layers. Easy to get lost imo. I'm currently trying to figure out a way to automate that using Photoshop actions or a script. It's a work in progress.
      Let me know if you have any questions! And if you want to share your images and if you use discord, the Naztronomy discord server (Invite link is in the description) has a place you can upload and share with the community.

  • @pawproarchive
    @pawproarchive 5 місяців тому +1

    So, you mention repeating the adjustments to each layer, to get the best detail results. I am a little confused what steps are suppose to be repeated. After you pull up the saved aligned layers, do I rasterize each layer individually and create an OG file for each layer with the radial blur step. My main confusion is flattening of the layers . . . that was just to shorten and simplify . . . so that should be skipped, correct?

    • @Naztronomy
      @Naztronomy  5 місяців тому +1

      Before you load the layers into stack, you'd open each layer one by one, then do the blur, subtract, and multiply methods on each.
      Then you save the outputs for each of those layers and load those layers into the stack. Then align the layers, convert to smart object, and then do a mean stack.
      It's a lot more work but for some it's worth it.
      And flattening/rasterizing the layers is needed in order to the "Apply Image" option to work. That feature doesn't work on smart objects so we need to flatten it into one single layer.
      Let me know if you have more questions!

    In your longer exposures you are adjust the image scale... no, that's not correct! How could the image scale change? What is happening is that for the longer exposures the stray light along the lunar limb is larger, making the difference image appear as though the image scale has changed. Don't do this.

    The most imporant thing about this process is to shoot the images you intend on using in as short a time period as possible. If they are too far apart, then the movement of the moon in front of the sun will make it impossible to align correctly.

      I don't think you'll get anything out of doing an HDR image of the partial eclipse. HDR is generally used to bring out details of the various layers in the corona (and other objects) but the partial eclipse is just one layer. You may be able to make the sunspot pop a little bit more.
      You can do HDR with the moon though because it has shadows, dark regions, and bright regions that all come out at different exposures.

      You may benefit from doing this process on each layer. My guess is that you are seeing the halow from some of your brigthter exposures. I had that too so in the HDR image I posted in the community tab of my channel, I only use exposures up to 1s.
