    Nice walkthrough James and a beautiful example of what you can get with a OSC. Personally I liked the colours and didn't think it was overdone at all.

      Thank you Logan. I've been meaning to put the 1600mm back on this scope but I keep picking out new targets with this combo :)

    Another great process and tutorial James. I don't think you went too far... it look very nice. Love the dark structures.

    Liked the final image. I’m actually learning from your videos and use similar methods on my images. I get decent results. Thank you for sharing the process details 🙏🏼.

    Ah the PHD ping of doom we've all heard that on some of our imaging runs, great walkthrough for Pixinsight to I'll have to try & get my head round it as I've been using Photoshop lately. Nice result at the end James clear skies.

      Thanks Dalek! Dang clouds ruining everything!

    Thanks for the walkthrough James I thought you came up with a very nice result. Interesting listening to you because I remember when I processed this image I was constantly questioning if I was over doing it. I don't know what it is about this target but I could never settle on a version🙂. I think you got a very nice balance overall.

    • @DSOImager
      @DSOImager  2 года назад +1

      I think you are right about this target. I'm thinking about pointing the Edge at it for a SHO shot to reveal all the intricate details inside there.... maybe. :)

    Fantastic capture James! I’ve yet to try this one as it’s pretty low for me.

    I personally really like how it turned out. A question though for you James- do you add the Luminance with stars usually or without? Or because it's a color image, thats why you didn't do starless before Luminance?

    • @DSOImager

      Thanks Isaac!
      Lately I've been removing the stars after adding Lum. So the workflow is Deconvolution on Lum > Stretch both Lum and Color > Blur color data > Add lum to color > Then remove stars.
      I've liked the results Ive gotten so far by removing the stars after stretch instead of removing stars while linear. And when I run deconvolution.. I want its affect to impact the stars. That said... my work flow is subject to change. ;)

    Hi James, very well done, I was most suprised about how smooth the linear data was, wow! I do have a question, or two really. First, why do you blur your color before adding lum back (as I saw in the comments) and how? Secondly, did you use LRGB comb. or pixelmath to add the lum back? Thanks and clear skies!

    • @DSOImager
      @DSOImager  2 года назад +1

      Thanks! Yea.. these newer sensors are amazingly low noise. :)
      The idea behind blurring the color data before adding the lum is to remove all color noise. I use multiscaleMedianTransform to blur it by disabling all the layers except the R layer.
      LRGB combo tool is what I used.. but pixelmath would work too.

      Makes sense, gonna try that on my own project, thanks!

    533...did you take video (Lucky imaging) or single images? If vid, frame rate with that camera? Thanks

    • @DSOImager
      @DSOImager  2 года назад +1

      Individual images. 316 sub frames, each 120 seconds. Gain used was 100.

    • @DSOImager
      @DSOImager  2 года назад +1

      I did use lucky imaging on my lunar eclipse shot. Frame rate was low... around 5fps.

    Very interesting image processing walkthrough with a fantastic final result. This "DarkStructureEnhance" script was new to me and a very nice tip. - Thanks for sharing & cs

    • @DSOImager
      @DSOImager  2 года назад +1

      Thanks Tully! The first time I saw someone use that script.. it was on one of @lukomatico's videos. :)

    Fantastic image. Thanks for sharing your process with us. P.S. I love seeing that you have a color_clone_clone_clone_clone1 in there. That made me smile because I do the same thing.

    • @DSOImager
      @DSOImager  2 года назад +1

      Thanks! Yea.. that clone_clone_clone thing gets a bit out of hand sometimes, doesn't it? 😄
