    Mate - as a newcomer to the hobby with a Seestar S50 and a steep learning curve on Pixinsight over the last month, I cannot tell you how helpful your channel has been. Once pay day comes around, I’ll be using your affiliate links for the exterminator plug-ins (using them on the free trial right now) as a small Thankyou but I wanted to reach out in person too. I’m a teacher with 24 years in the classroom and so I hope I have some credibility when I say that your instructional skills and approachability are fantastic. Just a thought for future content: perhaps offer a series of videos in which you coach a noob towards putting together their first rig and capturing/editing their first good quality images. That step up for me from a smart telescope without an EQ mount to a proper set up with all the gubbins that goes with it is terrifying right now so I’d find great value in that kind of a collaboration.

    Just reprocessed Andromeda shot on my 102edr and 26c with LP filters from a few years ago - 4 panes into one image. It looked ok before this tutorial! Yay! Looks epic now. The Ha from the Ha/Oiii filter I used too is standing out. There's a little area of green I can't shake though.

  • @WanderingNight1
    @WanderingNight1 5 місяців тому +1

    Cheers on another great video mate. A few questions/comments: 1) Why did you decide to stretch the stars with the galaxies and not remove them first and then stretch separately? I've found GHS takes away some of the star color and but using ArcSin to stretch stars leaves the color. 2) I've read and seen videos that indicate that BlurX on 'Correct Only' should be ran first before using SPCC. Then after SPCC, run the 'normal' BlurX. I know it adds time to the processing but other than that, what is your thoughts on that workflow? 3) Your method on using GHS to stretch the galaxy is the easiest one I've seen so far and I like the results - kudos! When I tried this stretching method on the Leo Triplet, 2 of the galaxies looked great but the 3rd was looking blown out. I tried to use a mask on the one galaxy but mask don't appear to work when stretching (only when using Curves). Any suggestions on the stretching when there's multiple galaxies? Keep those videos coming Luke!!!

    • @lukomatico
      @lukomatico  5 місяців тому +1

      Hey there mate! - Just want to start off by saying thank you again for your wonderful support, it's hugely appreciated!! :-)
      To answer your questions -
      1: I totally hear you! I try to stretch everything together for broadband targets now in order to keep everything looking as natural as possible (to my eye at least!) it's certainly achievable with other methods though, so if what you're doing looks best to you - keep doing it, 100%!
      2: That used to be the case yeah! running correct only first was sometimes much better - however Russell Croman says since the advent of model 4.0 of the AI it's generally no longer a required step :-)
      3: So happy to hear it's been easy to use!! - Regarding using it on multiple targets with different brightness levels, that's a challenge! - I'd probably say to give them an initial smaller stretch using the brightest of the galaxies as your reference, being sure to tame the core a little if possible with the SP, then make your second stretch attempt and see how it goes from there - regarding masked stretching, it should work as long as the mask isn't too conservative, I've certainly done that before in tricky stretching situations!
      - one other possible technique would be to stretch the brightest galaxy until it's just about overblown in the core, take a range mask on that bright core, and reverse stretch it a bit :-)
      Good luck! hope that helps and thanks again! :-D
      Luke

    I love your tutorials and have been the foundation that I build off of. I'm using Seestar images so they aren't as clean as yours. A lot of the videos I see people are doing gradient correction right after a crop and before image solver and SPCC. Also, I've been told I should be previewing a starless piece of the background for region of interest in background neutralization on SPCC. What do you think about this? Do you still think gradient correction should be done after image solver and SPCC steps? I hope you understand my question, thanks!

    • @lukomatico
      @lukomatico  4 місяці тому

    hey man, thanks for sharing your data - this was the best lesson I could ask for. I was wondering if it was my gear, processing tools or skills that i need to address to produce better images. Turns out everything bit by bit😂. I highly recommend this to all that are starting out that wonder if it is your data thats shite or is it processing. My C6N with ASGT with sony a6500 is actually decent and not as much behind your gear as I thought. I am processing with free tools and lack good noise reduction tool. Processing your data my way got me quite nice results with a bit background noise visible but i pulled out similar amount of detail.I lack sufficient integration time and my camera (or the way I use it) leaves me with a bit more noise that is uglier even after getting about 2hrs of darks at the end of the session. This was a.fantastic way to figure stuff out. Thanks again.This is a bit long but if you actually read till the end - can you share how much integration time this data has? If it was mentioned somewhere I missed it.

    Hi Luke, So on your previous video processing galaxies from RGB you did the gradient correction before doing photometric calibration, but here you did it the other way round. Any good reason. I'd have thought the former way was a better approach?

    • @lukomatico
      @lukomatico  6 місяців тому +1

    Second, good luck with your impending parenthood! It's going to be amazing. And nuts. And all kinds of other things! You're going to be an awesome Dad.
    Third: I just processed my new data of M33 (180sx86frames) using your workflow in this vid, and it looks amazing. However, my overall image result is very blue. Whereas your image of the Sunflower has much more oranges and reds. Is that a function of equipment used? In this case I used the ZWO 533MC Pro, with no filters whatsoever, and shot from a fairly dark Bortle 3 zone. I'm still somewhat new to Deep space astro and not always completely sure what colors things are supposed to be! Anyway, any pointers or tips are greatly appreciated, as always.
    Cheers and Clear skies.

    I am thinking of moving over to pixinsight from PS but I want to ask what may be a controversial question. When using things like noisexterminator and blurxterminator how much of the image becomes AI generated, and how much remains your own capture? I worry that it'll get to a point where the image is no longer mine but is an AI interpretation.

    • @lukomatico
      @lukomatico  14 днів тому

      I hear you completely mate! - as long as you use BlurXterminator in the unstretched/linear phase of processing it's able to do it's job accurately and without hallucinations 👍
      Regarding noisexterminator, that's free to be used at any time, it won't hallucinate details etc
      Hope that helps!

    I am really new to this and I am building my first rig. I love your video on how to start using PI. It would help me tremendously if I understood how the original image was obtained. Did you use a colour camera, what kind of filters and settings were used and how you stacked the images. One aspect I always wonder about is do you use the default settings for RGB or force it so all channels are the same on the histogram? I would also like to know if you are using short exposures because of your Bortle 7 skies? Are you using a cooled camera? Do you have a video you can point me to that might answer these questions? Thanks for your amazing videos!

When i run WBPP script, it applies an autocrop to my images and i don't have to crop any further.

    Small tip. You can set the option to show the structure protection masks. It allows you a visualization of what structure is being recognized and can remove some guesswork.

    You are an excellent teacher Luke! I especially like that you use the latest tools available to Pixinsight and you produce natural looking images with a relatively simple workflow. I learned how to process nebula from you with a 90mm refractor and just got an F4 newt and want to start imaging galaxies. This is just what I was looking for!

    Brilliant tutorial Luke. I always learn more with each of your videos. Thanks so much. For using SPCC on a nebula shot with an OSC and L-Extreme filter on my IMX571, should I choose the average spiral galaxy as the White Reference, or something like photon flux? Thanks.

    • @lukomatico
      @lukomatico  6 місяців тому +1

      Hey Dr.B! - I'd probably use the average spiral galaxy reference, but there's no harm in making a clone first right before application and trying both ways - you may find that you prefer one over the other! :-) Good luck mate!

      And I just rewatched your OSC Nebula video from three months ago & see that the way you used GHS is quite a bit different than for this galaxy. Since I haven’t used GHS yet, would you recommend using each method for their respective targets?

      Hey mate! :-D Thank you and well noticed on GHS - my workflow has adapted a bit these days yeah, for nebula targets I do stretch a little differently though so as you mention, it's a good plan to stretch for the target rather than one rule for all, cheers! :-)
