When you come to stretch your data, as David Stearn commented below you may wish to try unlinked stretching! My advice would be to create a clone of your image right before stretching, stretch one linked, the other unlinked, then try NN on both - continue to process the one that you like best, close the other! 👍 Clear skies!

@SpaceCityAstro 20 дней назад

One tip about BlurXT - if you run it twice - once with the 'correct only' box ticked, that'll get rid of the chromatic abberation and misshapen stars. Then untick that box and run it a second time like you normally would. Then your stars will be much cleaner.

@lukomatico 15 дней назад

Cheers mate! - I think the need to do this has gone with the current AI version though, worth testing both ways to be sure! :-) Clear skies!

@w8bya Месяц назад

Nice to wake up this morning and see another fine processing video from you Luke. They have helped me tons and each time I watch one I learn something new. I did not notice you mention which engine in BXT you picked (V2 or V4) and also if the elongated stars in the corners got fixed but I suspect they did. Thanks for sharing !

@lukomatico Месяц назад

Hey mate! :-) Thanks so much for your lovely comment! - RE which AI, it'll be V4 for certain, and the stars were indeed fixed by bxt, what a great tool!! Clear skies my friend

Great video as always! Going to try it on my first narrowband capture ever of the Eagle nebula! I was doing some testing and didn’t expect to be able to capture any data just seeing if I could get focus and stuff like that. I didn’t even polar align. Somehow my guiding was 0.7 arcsec so I just picked a target from the sky atlas in NINA and left it overnight. Using L-ultimate and 4 min subs I got 3 hours of data. I was shocked to see the images! Never seen that many stars before since I was doing broadband from Bortle 8/9 skies.

Thanks mate!! glad to hear it worked :-)

@FrootyRecords Месяц назад

Great result Luke!. As its so nice, I would have definitely tried doing some clone stamping touch up around that bad halo star when you had the stars removed. I think it detracts quite a lot from what is otherwise, a very beautiful image. Just my opinion.

@lukomatico Месяц назад

Thanks for the feedback Dave mate!! I don't like halos at all, but it'd have felt a little naughty to try and hide it I reckon haha, hence just 'acceptance' being my strategy at the moment 😂 All the best! 👍👍

@MrGeert1972 Месяц назад

With the new seti Astro star stretch I us starX before stretching and stretch starless and stars separately and that works great. I also do split my channels and do blurx and NoiseXterminator per channel and than linear fit LRGB combination before gradient correction

@AlexN-Astro Месяц назад

Awesome as usual, I've been using your previous osc to hubble tutorial to work with my images from my Artemis C pro and Askar d1 6nm dual narrowband filter with varying results. I have a form of colour blindness that makes processing astro images really complicated in broadband, but in narrowband you can't really be wrong, as it's all artists interpretation of the data... Got my Bahtinov mask from your ebay store the other day and resolved an issue I was having with my oag and main cameras focus being slightly out, guiding was much improved as a result, so thank you for that!

@Oamaruastro Месяц назад

That was very useful and well done-thanks very much! And while it’s hard to fix that halo in Pixinsight, you can deal with it pretty easily in Photoshop if you bring the starless image into Photoshop and use the “remove” tool on it. Does a pretty credible job if you aren’t opposed to that sort of thing.

@lukomatico Месяц назад

@andreacesanelli759 Месяц назад

Thanks Luke for the 'refreshed' version of your OSC processing workflow. Normally, to avoid touching unwanted areas and to be more 'selective', I adjust the two masks with histogram transformation. Do you think this is a good practice? Cheers mate and clear skies 🔭🌃.

Very good! Could you explain further the formulas for the color masks and mask blur?

@lukomatico Месяц назад

Thanks mate! Bill would be the guy to ask about the specific formulae though! 👍

@davidstearn1342 Месяц назад

Luke, Why did you use a linked stretch instead of an unlinked stretch? Based on Bill Blanshan’s recommendation the Oiii and Ha look better if you use a linked stretch prior to NBN. An alternate workflow is to use Color Calibration then GHS prior to NBN.

@lukomatico Месяц назад

Great comment mate, I'd suggest for people to make a clone prior to going nonlinear and try both ways - I've had luck either way, but I agree it could be a useful addition 👍 Cheers!

@kristofcappoen43 Месяц назад

I LOVE your work, and as a newbie I need some help finding some of the plugins, your HT_Strech, Your masks and so on are there video's where it explains how to make those. And last but not least, how do you create a start page with all the shortcuts? I tried with saving it as a project but DBE and ABE really don't like each other and cause an error. Thanks for your time and effort to make these video's

@lukomatico Месяц назад

Thank you for your kind message mate!! I don't have videos on how to make plugins etc, those ones you referred to were created by my friend, Bill Blanshan 👍 Re: saving process icons, you can usually use the small arrow in the bottom corner of a window to drag a shortcut onto your workspace, arrange them how you'd like, right click an empty space on the workspace and press 'select all icons', then right click again and 'save icon set' this should allow you to save them out, so you can right click and 'load icon set' the next time you use pixinsight 👍 hope that helps!!

@briankotak403 Месяц назад

Great tutorial Luke. I use a very similar process workflow (based of course on your previous video). Just wondering if you can partially get rid of that nasty star halo by doing a Clone Stamp over it in the starless image. The stars only image looks ok but the major halo is in the starless image. Worth a try! Thanks again buddy! Dr B from Manitoba, Canada 🇨🇦

Hey Dr. B! :-) You could indeed clone it out quite well I bet, but I feel it's best just left warts & all :-D Cheers!

hello, first, thank you very much for your tutorials, I learned a lot and still learning. Your videos are very clear and cool. I tried this tutorial on m16, but I had an issue : the center zone hoo selected with narrowband was too big, and all the center result in a big blue area. So my question is : is it possible to reduce the area (like in mask range) ? or this tutorial is not adapted for m16 ? thank you.

Superb and very useful video Luke, 👍🏻 can I ask why you used the HOO setting in Narrowband Normalisation rather than the SHO setting..?

@ABCMO-bl5pi Месяц назад

Luke, thank you for creating this valuable video. A question I have concerns screening. As you did in the video, I use the “unscreen” option in StarXterminator and then rescreen the stars when I put them back into the starless image. However, I don’t know what “screening” is and I haven’t found an explanation online. Any chance you could provide a brief explanation?

@lukomatico Месяц назад

Hey there my friend! screening is an option to allow you to remove and reinsert the stars less destructively than pure addition does - addition does just that, adds the starless + stars together, inevitably leading to bright spots & burnout where stars are reintegrated to the already bright image, rescreening is more akin to a gentle blend, helping preserve highlights - Hope that helps!

@ridearocket Месяц назад

Hey Luke hope all is well. Many of us in the hobby are stuck to free software. I feel like many of the bigger astro youtubers mainly use PixInsite and create PixInsite tutorials. Have you ever used the PIxel math tool within Siril? And if so, would you consider making an in depth video on Pixel Math in Siril? I know the tool isnt identical to PixInsites Pixel math, but is still very powerful / capable. Regardless. Great work and clear skies.

@realmcerono Месяц назад

I think nobody should cheap out on software. It is essential for AP. Compared with anything else you need, pixinsight is not that expensive (they just raised the price to 300usd, I paid 230 back then) it is a one time buy and will probably not get cheaper with time.

@lukomatico Месяц назад

Hey mate! - my friend @DeepSpaceAstro has been making a lot of wonderful tutorials with Siril, - he may have what you're looking for! - around the time Siril got Pixel math I was already knee deep into PixInsight so decided to just stick to what I was currently learning, - it may be something I'll revisit but I feel like I'd need to relearn the program at this point to make worthwhile content - cheers! :-)
