    An excellent (as usual) tutorial that is logical and makes good use of if the new tools now available. 👍🏾
    I guess that with great data, one can perhaps dispense with the use of LHE, unsharp mask. etc.
    I am currently imaging Eta Carina and Seagull, so will soon put the workflow to the test.
    Keep them coming ….

    I have greatly appreciated this tutorial and the one on the DBXTRACT script and was wondering if you could offer an opinion. It turns out I have both the D1 filter and L-Ultimate filter along with the D2 filter. I am thinking of selling either the D1 or L-Ultimate as they are somewhat similar. I want to create SHO images as you demonstrated. Would you care to recommend which filter to keep? Would it be better to keep the matched pair of the D1 & D2 or use the L-Ultimate with the D2?

    • @viewintospace
      @viewintospace  Місяць тому

      Depends... 😁 On paper the L-Ultimate filter is the better one. But: 1. Optolong is known for the non-existent quality control. So have a look at exposures you took with the D1 and exposures you took with the Ultimate - where do you have less Halos? 2. Another consideration: If Halos are about equal and you do not live in an extremely light polluted region.... It will be much easier to sell the Ultimate than the D1..... simply as it is better known.....

    As usual, an excellent tutorial. You are the best! I use GHS a lot and have often had the background lighten too much after a GHS stretch. I quit GHS and use the Histogram Transformation tool to adjust the black point. Then return to GHS if needed. I find it easier to use HT than to do this in GHS.

  • @user-nd3sj1rr4l
    @user-nd3sj1rr4l 4 місяці тому

    For GHS mastery, I highly recommend Ryan and Dark Rangers Inc on UA-cam who in my opinion really makes it easier. The one hour Adam Block video was very hard to get through for me. Then I watched the Dark Rangers one and I was able to really master it quickly in a much shorter time. Thanks for the video - really helpful to see the new scripts in action and a cool way to fix the stars. How would you compare that to the method inverting them and running SCNR? Would be interesting to compare.

    • @viewintospace
      @viewintospace  4 місяці тому

      I would agree, Ryan has also a great video. While his is very intuitive, Adams was for me kind of an eyeopener and I learned a view new things. When it comes to the inverting and SCNR method, this is 💩 - it only removes the colors, so you basically end up with white stars. Some proposed using the Forexx script and that seems to give an equivalent result as these Pixelmath formulas.

I'm more of a "just tell me how to do it" and I don't need to know WHY for every single thing. Do you have a cut/paste link for the pixelmath formula for the stars? I'm not great at Pixel math...

    Truly quality content as all your videos! Having a question:
    I'm planning to shoot OSC with Askar D1 and D2 filters. Then use R from both images and combine 2 Gs and 2 Bs into synthetic B. Assuming I have 5h with D1 and 5h with D2 what will happen with noise? Will pixel math work similarly to single subframes? Moreover, if both filters pass o3 will the combination of their B and G channels increase definition in o3 structures?

    • @viewintospace
      @viewintospace  Місяць тому +1

      Have a look at this video: ua-cam.com/video/h8o0s6PFQyE/v-deo.html Use this script instead of Pixelmath, shoot about evenly with both filters and all will be fine.

  • @rayjohnson7437
    @rayjohnson7437 4 місяці тому +1

    Hi Sascha - great tutorial. You used R, G, B filters in your SPCC section whereas the actural filters in this processing run were HSO. Could you let me know your thinking here, many thanks.

    • @viewintospace
      @viewintospace  4 місяці тому +1

      Hi Ray This is the most asked question of this tutorial - seems to confuse everyone alike 🤣 Anyway, reason is that when you use these Pixelmath formulas, you try to generate RBG channels, so kind of like the stars were RGB stars and not narrowband anymore, so from that point also the filters would be then kind of RGB filters. It really does not matter which brand you chose as this is only an approximation, but you see in the curves that it work quite well like that.

    Wow. Very impressive workflow. I use a OSC with a dualband Ha and Oiii filter. Is there a way to create a synthetic Sii channel?

    • @viewintospace
      @viewintospace  4 місяці тому

      Nope!!! You will find some tutorials which claim this is possible, but in reality you only create a fantasy layer, as it you did not catch the Sii, how should any process know how it looks like? Have a look at the Askar Colormagic D2 filter. It‘s not expensive and gives you the chance to shoot Sii - you find a few videos on my channel about the filter.

    Great video Sascha. I did encounter one issue though. It involved stretching the stars. So I did exactly as you showed and yes the Histogram Transfer looked the same as yours. However when I dragged the triangle from the Histogram transfer to the stars image, the star diminished in brightness. How is the screen transfer getting set to the values of the stars image?

    Thanks for another nice video! The only part that left me scratching the head is how in SPCC you went on to select RGB filters even though the data was SHO. Is that a normal practice?

    • @viewintospace
      @viewintospace  4 місяці тому

      With the formulas we made an attempt to bring the data back to RGB level and so to chose any RGB filters is closer by the reality we try to synthesize. As you can see with the curves, it works quite well. BTW, for SHO pics, SPCC can not be used at all.

    • @viewintospace
      @viewintospace  4 місяці тому +1

      No, I don’t and quite honestly with an OSC cam it’s so easy to shoot RGB stars that I would strongly recommend to go with the real stuff 😉

    Hello thanks for the video but wouldn't you use Narrowband filters mode in Spectrophotometric ColorCalibration as your masters were sho not rgb or does it not matter for just the stars?.

    • @viewintospace
      @viewintospace  4 місяці тому

      Given we mix it all up with formulas it is neither - so use any RGB filters in SPCC and as you can see the result is quite good.

    • @viewintospace
      @viewintospace  4 місяці тому +1

      I might do an RGB tutorial sometime, but in general when talking about this one here, you can use that also for OSC cameras. Either you use dual narrowband filters (like Askar D1&D2 filters) to capture the 3 emissions, or you only go with HOO and you adapt the few parts where it deviates. But 90% is the same no matter what data you have.
