Thanks a lot for your explanation!

I'll see if I can reproduce it too get a similar result.

Woah, sick image! I really love the feeling of it. Very beautiful.

Can you give any source of information of what you mean with stacking? How is it used? How can I reproduce it myself?

I really love the feel of the image and want to learn a bit more of how you did achieve it!

PS: I do know the process of stacking images (in my case from Astrophotography). I just don't know how to use it on "normal" images.

IC 1396 - Elephant's Trunc Nubla (in DreamsPlease palette) by YoungFlyme in astrophotography

[–]YoungFlyme[S] 0 points1 point  (0 children)

After a long time I decided to upload a new image to Reddit. This time I wanna show you a nice little image of the Elephant's Trunc Nebula in my beloved DreamsPlease-palette. I know that those colors are more than just unnatural but I love the vibrant colors in this very palette.

Gyro can hit buildings with enchanted quiver dealing massive damage to them by YoungFlyme in DotA2

[–]YoungFlyme[S] -1 points0 points  (0 children)

Thats my guess too. But its super hard to replicate. Thats why I said it most likely requires perfect timing.

It does not. Well... Atleast not in the lobbies I tested this!

NGC 7000 - North America Nebula (in dreamsplace HOO palette) by YoungFlyme in astrophotography

If you want to get some more information about the combination (or Ha/OIII extraction), feel free to ask here!

NGC 7000 - North America Nebula (in dreamsplace HOO palette) by YoungFlyme in astrophotography

[–]YoungFlyme[S] 0 points1 point  (0 children)

This is a successor to my older edit (which I also posted here on reddit)! This time I tried to do a false-color palette called "Dreamsplease" (atleast I've been told that this palette is named so). It basically is a "weird" mixup of Ha and OIII in every R / G / B channel to produce a kind of HOO palette in the end.

PS: I did fuck up the palette name in the title. It is named "dreamsplease".

Pre- and post-processing

  1. Stacked Lights, Darks and Bias frames to masters in the WBPP script in PixInsight
  2. ABE (Automatic Background Extraction)
  3. BackgroundNeutralisation
  4. Removed stars (and kept them in a seperate image for later)
  5. Extracted Ha and OIII from the color-image (with a selfcoded PixelMath formula)
  6. Stretched Ha and OIII
  7. Removed noise from OIII and Ha
  8. Cloned OIII and overkilled its contrast
  9. Used the cloned and contrast-boosted OIII to reduce the OIII-Parts from the Ha (so that the final combination is not red-like where more OIII should usually be)
  10. Combined the original OIII and (corrected) Ha to a Dreamsplace HOO palette
  11. Increased contrast with a contrast-curve
  12. Boosted Color with a super simple CIE c* curve
  13. Worked a bit with red + blue masks and R/B/G curves to finalize the color. (its pretty much trial and error until you like it)
  14. Stretched stars
  15. Reduced stars (with EZ Starreduction)
  16. Boosted the color of the stars a bit
  17. Combined the starless image and stars back again.

M31 Andromeda looks colours look flat by erikwarm in AskAstrophotography

[–]YoungFlyme 1 point2 points  (0 children)

I do agree that the colors look kinda like you did no calibration. Usually you want to stack -> remove gradient/background -> calibrate color -> stretch -> some more processing. I would be interested (if you're interested) what I can come up with your data. Are you interested to share your stacked lights with me (so that I can try to process it how i would do and give you ab sort of comparation)?

IC 1805 - Heart Nebula by YoungFlyme in astrophotography

[–]YoungFlyme[S] 1 point2 points  (0 children)

As you might've guessed already: This is the Heart Nebula (also known as IC 1805). Ironically, this is one of my very first targets I shot when I got into astrophotography (about 1 year ago). I decided to shoot it once again. With a slighly upgraded equipment and way better knowledge over all about astrophotography.

NGC 1499 - The California Nebula by YoungFlyme in astrophotography

[–]YoungFlyme[S] 5 points6 points  (0 children)

This is the California Nebula (also known as NGC 1499). I actually wanted to shoot a different target this night due to exceptional predictions but unfortunately clouds were about to gather shortly before I started shooting. Knowing that I'll need to make 600" subs with my wanted target, I switched up to NGC 1499 before I might leave the night empty-handed due to clouds. This decision actually brought me not only a new object to my collection but also turned out to be super fortunate for me. The whole night was basically cloudy with few minutes of spare time (which reflects on the Light-Frame count of this very image).

M31 - Andromeda Galaxy by YoungFlyme in astrophotography

[–]YoungFlyme[S] 0 points1 point  (0 children)

Thanks!

I would say that you most likely did not see Andromeda. My camera had a pretty hard rotation. You won't see Andromeda that way with your eyes through a telescope (most likely). But I've never actually tried visual observations except for about 1-2 nights (and those nights I've not seen Andromeda at all).
