At the moment I'm experimenting with using the Highlight Protection, a lot. I do a bunch of small stretches, and for each one I'm dropping the highlight protection down to about 50%, or just making sure the highlights aren't blown out. It's handy for objects with a really bright core like galaxies or the Orion nebula, because you can bring out a lot of the dimmer parts of the image without blowing out the core. But my problem is that I just never know when to stop, and I always go a little bit too far!

Thanks for posting that! It really helps myself and others to see the different ways of stretching! I know what you mean about over doing it. I'm the same way. I've started walking away from what I'm working on for ~10min., then come back to it. Sometimes I look and think, "Whoa that's way over done!" when I thought it looked good prior.

I just discovered your channel and you taught me how to use Siril, thanks! I have one question though… is there any way to save an auto stretch? On most images I can do a better stretch, but on a few a good starting point would be the auto stretch itself…
@DeepSpaceAstro11 ай бұрын
Yep. After you set it to AutoStretch, click the button with the Camera icon in the top-right corner. Click 'Save as unique file' and it will save the image as a .png in your working directory.
@DeepSpaceAstro11 ай бұрын
Oh wait. I think you may have meant save the autostretch and then continue stretching from there? If so, Open the Histogram Transformation, click the button with the gear to apply the autostretch, then click Apply. You should probably run a background extraction, and color calibration before that though for the best results.

Hard to say without seeing what you're talking about. Does it look good in the AutoStretch view? If so, try a very aggressive first stretch with GHS with the stretch intensity all the way to the right. Stop there, and switch to Linear Stretch under Type of Stretch and move the histogram as close to the left edge as you can without clipping data. Then go back to GHT and stretch as I show in the video.
