  1. I'm totally new to astrophotography processing. I stacked my 150 images of Andromeda Galaxy with darks and bias. I imported them into Photoshop, but when I went to stretch them all the data was way on the left, even though I can plainly see the galaxy in each of the light frames. And since it was all agaonst the left, I couldn't use the sliders to stretch the image. Very frustrating. Any suggestions?

  2. Hardly a tutorial when you're just ripping through the process with no explanation as to what you're doing or why. It's a good video to show what stretching can do.

  3. Did the whole tutorial to see how it would affect my own procedures, was great!, image I was working on is way better then before. I also imaged this nebula, I called it the embryo nebula 😂

  4. I saw Trevor mention an illuminated reticle he uses for aiming his telescopes. Anyone (or Trevor) know which one it is? I have found a few online, but they seem to mostly be fairly high mag, which would be so highly magnified on my 1000mm 8" newtonian. Thanks!

  6. "the cooler bluer ones" at 4:13 seems a bit wrong ;D they are the HOTTER ones obviously, maybe a poor choice of words, but it seems to be astrophysics 1-0-1

  7. I know this is an older video, but this helped me so much on editing my first longer stack of data, i really appreciate you putting out these kind of videos. ill have to try out those astronomy tool set when I have some extra cash to spend that you suggested we use. I can definitely see where it would help me if i had those tools

  8. When the video got to around 39 min I suddenly became aware of all the strings of stars, like strings of pearls throughout the entire image. Is this an artifact of all the processing? There seemed to be less randomness to the star field than would naturally be observed.

  9. This past weekend I finally achieved a long time goal of capturing and processing my first astrophoto. I just wanted to say thanks for all the content you put out, Trevor. This video especially helped me learn techniques and ideas for editing my shot of M42.
    Just wanted to spread some good news in all the chaos of the world.

  10. If anybody's on Mac and wondering the shortcut for the "stamp" he mentions at the 7:00 mark it's: Shift + Option + Command + N + E. Took me a bit to figure it out 🙂

  11. A lot of people think of space as way out there somewhere. No, we live in it! If you’re not in a city, go outside and look up. Space is laid out before you and you’re in the middle of it all!

  12. Trevor, just one last thank you for this excellent tutorial. You provided more than enough for a first time PS user like me to explore Photoshop by applying your techniques, and to confidently adventure forward to find my own methods. Just a couple of weeks ago, I had no clue how to go about this. Today I have my own pre and post processed images of M31 and M33, both from my Bortle 8-9 backyard. They are far better than I ever imagined my fist images could possibly be.

  13. So when you convert to a 16 bit image, the HDR toning window pops up… Im not getting that popping up to choose exposure and gamma as you say we should use. Im using latest updated Photoshop 2020. I see the HDR toning under image->Adjustment->HDR Toning. Does it make that big of a difference to do that after converting to 16 bit since that window doesnt pop up? Or…?

  14. I think your video has provided tremendous insight into the depth of image processing. Seeing how you do it in Photoshop was an added bonus as far as I'm concerned. Seems to me the rest is up to those of us who want to explore it by doing, not by being taught. I know I'm stoked. Thank you very much for sharing some of your experience. Well done, sir.

  15. I am pretty basic in Photoshop, had to slow the video down and watched key parts of it about 5 times to see what you were doing. The cursor goes whizzing around ridiculously fast and you do things in a flash without explanation. It is good info, but if they are all like this, I am done with them.
