Great video! Love your content, it’s been helpful! Thank you
Looks fantastic Ryan
GHS is a tool I need to master and currently I’ve been avoiding it as my skills aren’t quite there yet so this is great and just what I need
Congrats on the sponsorship and can’t wait to see the Photoshop vid
Cheers
Si
Great video, so crazy how much more data you can get out of an image beyond stf.
Thank you Ryan - You are helping me improve my stretching ability. Looking forward to your Photoshop tutorial.
I'm in the same boat. Can't wait for that photoshop tutorial
Merci encore pour ta vidéo,les explications…sympa.
Ryan thanks for the video. Thanks to Pt 1 of GHS I’m getting use to GHS (especially since losing EZ Stretch after every update). Still trying to utilize bottom sliders. Will definitely try to use the cheat method soon. Thanks!
Good to hear! I realize that most people when I help them out struggle on the first couple stretches and typically STS doesn’t do a bad job. It just isn’t maximizing your data so I tried starting with an STS a few times and it actually worked out pretty well.
But as you can see, you can pull out a lot more by adding a few more stretches with GHS. I wanted to really highlight using the color modes on this one, since I did highlight some of the other sliders as you mentioned, in part one.
Hey Ryan ,
On a wet day in Queensland Australia I just had a crack at your Telescope alive data of the Blue Horse .Excellent data but IMHO I wouldn't be happy paying $ with it as it appears their flats didn't work too well with obvious orbs in the neck below IC 4601, to its left and in the cheek , actually all over . The GHS is a real animal that will take some mastering but I can see it has it's place. Thanks for the tutorial . They are very informative and professionally presented. cheers
Thank you! Some of their flats aren’t always 100% up to date but most are. The data is very good each site is different but most have a 600M and Tak 106FSQ, the Chile, and Spain location have a bigger exotic scope too and same camera. It’s honestly pretty cheap. You could get a silver membership with my link at a discount and have enough data to do a couple nice images each month during a bad weather spell for a few bucks a month it’s not much at all.
@@darkrangersinc Hey Ryan, I really appreciate the reply . The remote data sounds like a plan ,thanks for the info. If it is OK I will post an Astrobin link with my rendition here. Cheers
Can’t wait to watch this one! It’ll be a while though
Have some data ready and you should be able to go right along with it!
I acquired data from Telescope live after I saw the fighting dragons and then found out I couldn’t get it here in Northern California. In my opinion I’ve got all the nebulas I wanted with them. Awesome and yes your processing skills improve.
Awesome glad you went for it hope you used my link to get 50% off your first couple months!
Excellent video my friend!! I have a tip, instead of using linear point to darken the background (this clips stuff), you can compact the data so you won't lose anything. Change the graphic view to LOG, place the symmetry point at the beginning of the ramp, send it to SP, then bring the highlight protection slider all the way to the left (it will stop when hitting the symmetry point), bump local intensity to max and then move Stretch factor and you will see the background darkening. This will preserve your data. Hope it will be helpful and thank you for the great channel!!
Oh yeah log view is helpful and something I incorporate typically after the first or second main stretch… For this tutorial we wanted to keep it a little more simple because a lot of people are trying to nail the basics.
The nice thing about using the linear slider is it tells you when you’re clipping so you can always darken it until you clip and then stop there and usually it takes you right to where you want to be as it did in this case…
Personally as I mentioned I like to be .15-20 for the background before going into photoshop so I still have a little room to work with. And in this case it got me right at ~ .18 so for the sake of a simple way to accomplish it that works.
Once everyone is feeling good with this level I’ll just into Log View and some of the other features.
@@darkrangersinc very nice, using this technique I described you can put the background dark level with precision without clipping anything
Haha looks like you live in the UK 😂 good video
Man it was bad got to shoot last night and next few nights look good

Ryan. Thanks for the video. I have a question which might be a bit basic but….why are you applying GHS to an already stretched image (with STF) ?.
Well, I think it’s pretty clear the difference if you watch towards the end to see how much more you’re able to get out of the data beyond just the STF. The reason that we’re starting with the STF is because it’s a bit of a short cut.
You can start from scratch, but it saves you time and gives you a good base image to then pull much more detail out of the whole point of GHS is to get more data out of your image than a standard curve stretch
@2:58 you mention you did a lrbg recombination. But you also said it was a one-shot-color exposure. You lost me there... :(
Two different images: I’m talking about M45 being shot with my OSC. I made a comment just so you know I’m not cherry picking good data (because it’s T-Live data) I also tested it with my own data on M45 I shot with my OSC camera.
The Blur HH is monochrome though (LRGB). for the sake of the tutorial though, it honestly wouldn’t make a difference either way the steps for the actual stretch portion would be the same if it was color or monochrome dats. Hopefully that clears it up for you 👍🏼
