Processing M31 With New Amazing Techniques

[@ClearAmbientSkies]

This video and the one about Bode's, a few years ago, are certainly in the top 5 of all the videos you've ever made. Thanks again for sharing your knowledge and experience. I've learned a lot just watching. Your video about 'The Beast' is in the top 5 too just because it is hilarious if anything. Great image. Your APOD is overdue.

[@enteringintospace4685]

Wow! Thanks so much!!

[@normhughes9777]

this is great. I have just completed shooting M31, now i get to try your technique. excellent final image. thanks for your time putting this together for us.

[@Astrobloke]

That is one hell of an image Steve. Love it. Now I am going to have to image it myself, add it to the list.

[@enteringintospace4685]

Thanks Glenn! M31 should have its own season...lol

[@DeveshPande]

Excellent Steve! Just in time. I am stacking my data right now and will try to follow along

[@enteringintospace4685]

awesome! Let me know how it turns out!

[@sebyromano75]

Right answer Steve . I learned so so much from your videos. I consider this one probably the best since finally I learned a good way to get the stars right!!!!. Please keep up the great work. Seba

[@jonathanpearceff]

Great video. I like the way you added Ha to the R and Lum layers.....something I will try when I get some Ha data.

[@enteringintospace4685]

Thanks!! Let me know how it turns out for ya

[@waldemarwitt764]

Thank you!

[@SimonsAstro]

Wow Steve, incredible image of M31 mate😀 makes me want to do mine all over again🤣 love the new technique’s! Clear skies!

[@enteringintospace4685]

Good luck Simon and thanks!

[@Kinderriegelfan]

MANY THANKS FOR THIS GREAT VIDEO!!! This helps me alot!!! Greets from germany!

[@enteringintospace4685]

Thank so much!!

[@mupangamwanakatwe1300]

Yet another superb Master-class in galaxy processing, filled with great tips and tricks!! Many thanks for sharing. Can’t wait to get some serious data with my new ASI533MM and Antlia filters over the next two months and try out your approach. Great stuff Guru, keep ‘em rolling in !!

[@nikaxstrophotography]

Nice work Steve the vast Nebulas in that galaxy must be an awesome site for inhabitants in that part of the universe. you captured them really well

[@enteringintospace4685]

Thanks!!

[@AlpheccaMeridiana]

right now i'm imaging iris, this vid will surely help me nice timing!

[@viewintospace]

Hi Steve Thanks a lot!!! As live goes, I just had the opportunity to shoot M31 at a star party and your tutorial was a huge help and has some really good tricks!!!! If should really be the go-to tutorial for any Ha-RGB Workflow. Some comments and experiences when I went now though it: 1. SPCC: IMHO there is not reason not to use it. You can even switch from Average Spiral Galaxy to Galaxy 1b to match the color of Andromeda perfectly. The HUGE advantage is that a lot more color is already in the pic and I did not had to go through all the saturation. 2. When you use SXT in a linear pic you do NOT have to select "Unscreen" - this only optimises the processes when you use it in the non-linear stage (see SXT manual) 3. I have the same issues with the range mask - it looks perfect in preview but then the executed pic is much brighter. I started to use also in these cases ACDNR, but this is really annoying - we should figure out what goes wrong here....

[@enteringintospace4685]

Hey Sascha! Thanks for the stx tip. I guess I assumed unscreen had to be ticked for the pixelmath formula to work adding them back. Good luck with your next M31 project this year. I think I'm going to project M33, try to really resolve all the nb structure in it.

[@DSOImager]

Great image Steve! I shot M31 last year.. going to try and take this year off... if I can, lol.

[@enteringintospace4685]

Good luck! Thanks!

[@rodneydingman267]

I did that ha technique in a video a few months ago , you explain and execute it way better though . Awesome image

[@omarlorentz99]

Nice video. Couldn't the "dynamicbackgroundextration" process be done faster and more efficiently after removing the stars from the photo with processes like starxsterminator?

[@nikivan]

Excellent video, thanks for sharing. To my eye, the periphery of the galaxy shows a bit of violet hue, which could perhaps be neutralized a bit. But it could be just my eyesight deceiving me.

[@markussiedler9903]

What is the formula for Oiii instead of Ha?

[@RigoFromSpain]

Whaauw like it, will take time to manage that I my shots, but amazing Steve !!!!

[@markussiedler9903]

I do not have a mono camera, how is this work, if i do not have red blue and green pictures?

[@MexximusUK]

Nice video :) For anyone doing a OSC workflow with this what do you do at the Luminance stage @37.20? Can this step be skipped or would it be worth creating an artificial luminance and carrying on the the rest of the workflow? Thanks

[@enteringintospace4685]

Thanks! Yes I would definitely recommend extracting a luminance image and processing just like I did mine then reapplying

[@MexximusUK]

@@enteringintospace4685 Cheers for the reply I appreciate it! Will add this to my workflow, great results so far.

[@ghanagankhuyag3087]

HI i followed you video and ended up range selection mask is incompatible message?

[@ten101337]

Can you also do some processing with both Ha and Oiii addition into LRGB?

[@astrobob9432]

Where can I find the pixel math expressions you were using? Thanks.

[@beautifulworld1988]

Whats the name of the song in the background ? Fantastic work.

[@petesastrophotography]

Excellent work Steve. I've always struggled with getting the color right on M31 (pretty sure it's down to the L-Pro I have been using). Looking forward to having another go this year with a new mono rig in bortle 4 skies (all my previous images have been from bortle 7).

[@enteringintospace4685]

Thanks!! Yeah it would work exactly the same. Split your channels and pull the luminance.... add the ha to the red and lum images and then recombine your rgb. Processing the luminance separately and apply to rgb after its stretched.

[@goldfish31ful]

Nice how you isolated the Ha in that image

[@enteringintospace4685]

Thanks, yeah the ha mask makes a big difference.

[@chrisaddison351]

Wow your videos are Amazing, just one question could I follow these steps with a OSC Camera by just simply splitting the RGB then taking it from there or would the results not be great. Thanks Chris

[@anthonygraham6449]

Thanks Steve. Background music hurts. Lol.

[@markussiedler9903]

Hi, great Video. But if i do Pixelmath with the formula, it gives me a failure message. PixelMath: Processing view: Ha *** Error: No such image: ((Ha*80)-(red*3))/(80-3) ~~~~~~~~~~^ The file is definitely called Ha i have L-Ultimate with 3NM

[@pierre42600]

m a g n i f i q u e

[@RJ-cu4cj]

Definitely will need to play with your tutorial for OSC.

[@enteringintospace4685]

Yeah, once you split the channels we're basically at the same point

[@RJ-cu4cj]

Disappointed. Great video but I find presenters should be answering the questions of subscribers/viewers in order for everyone to get the full benefit of these tutorials.

[@enteringintospace4685]

I make a point of answering and responding to everyone , scroll down....but KZbin notifications suck so I don't always see them to know when they come in. Thanks for taking the time to try and make me feel bad.....didn't work!

[@astrophane6455]

Wow... i really like your process, i shoot with OSC (294mc pro, not very the best) but i will try your process soon. il like work with pixelmath and i grab each one i find on the web, but i never see isote ha or isolate oiii and when i see how it work in your process i was impressed. for ha isolate ha is: ((ha*80)-(red*7))/(80-7) and add ha is: $T+(new_ha-Med(new_ha))*5 for oiii isolateOiii maybe is: ((Oiii*80)-(blue*7))/(80-7) correct or ??? add Oiii is: $T+(new_Oiii-Med(new_Oiii))*5 I'm not sure for oiii? Sorry for my english, for a french canadian is not very good The weather has been so bad this summer and still is, i think i will pratice your process really soon. Thank

[@enteringintospace4685]

You got it! I also shoot oiii for galaxies so I just modified the equations to be able to add the oiii to the blue.
