Well that's what I thought, the red just pops out so it must be legitimate data. Unfortunately, it can quickly over saturate the image and everything in it, so you must have been very careful in your processing in order to preserve it and the brown nebula. Well done.

I have seen this called an extended red emmission nebula (EME). I am not sure what that means.

I guess one sure way to see if the data is truly hydrogen is for me to capture 10 hours of 3nm Ha and see what's there. Of course, if I do that, someone will need to belend it with the rest of the data.. HAHA! More work.

Never doubted it was legitimate, something was there, just hoping I wasnít doing something wrong processing it and turning it purple. You arenít kidding its tricky! It easily overcomes the other data when stretching. I have never integrated Ha, but if you are willing to spend the time imaging I will certainly give it a shot! It is getting cold here and snow is just around the corner. It will give me something to do this winter. I donít have a dome so donít know if I will be doing much imaging the colder it gets.

Hi Dave,
I tried a couple more techniques on your image and I think I am satisfied with this one. There is a lot more depth and 3D feel to it. When you zoom in on the full scale image, I especially like the structures around both sides of the tail of the central nebula and branching off to the upper right. You can clearly see the cloud structures. You did a great job gathering this data. Thanks again for sharing.

hello dave, thank you for sharing your data and here is my go with photoshop. bigger version on image click.

Steve,

Your image is very nice. You did a great job with the stars. Did you use a star mask? I think Yuriy's image has some artifacts in the star centers, but yours are very clean. Your image looks awesome.

Kozzinna, your image looks fantastic also. It's amazing to see all of the different versions using different processing methods. I am still struggling with PixInsight, though Warren Kellers new videos are helping me move forward.

Unfortunately, my skills end at preprocessing. I can capture the data, calibrate it and stack it, otherwise I understand very few processing procedures in PixInisght or Photoshop. It really sucks being limited like this. I feel like my hands are tied.

Anyway, I just posted some dusty data for vdB152 which you are welcome to process. I had a limited number of subs so it's not the best data, but I plan to capture more tonight.

The forcast for tonight is excellent transparancy and above average to excellent seeing conditions.

Soon I'll have so much data I will need lots of friends to help me process it all!

Dave,

Thanks for the opportunity.
Nice data you have there - perfect focus and guiding
It's remarkable that you have it open for everybody


Here is my modest attempt:

Mark,

Great job. Your image looks awesome. What software did you use to process it?

I really don't mind sharing my data. I enjoy capturing it. It is a technical challenge and that's what I enjoy most. I am not very creative artistically speaking and that's probably why I struggle with the image processing.

I am sure if I had an expert sit with me for a couple of days I could get a monkey's handle on it and replicate what I am taught, but I really struggle to figure it out even with online tutorials. Most of them assume so much knowledge with either settings or some small step they failed to point out. Then I waste several hours and get frustrated trying to understand why I can't do the same thing they just did on the video!

Thanks for processing it. It's beautiful.

Thanks Dave!

I use PixInsight and Photoshop heavily.
I'd say it's a pity that you can't processed such nice images. May be we can sit together to get you up to speed. Just let me know.

Mark

If anybody has time, I've uploaded new fully calibrated (including flats, etc.) sums in YuriyT folder on Dave's ftp server (check first message for login info).
You will find L_Synth and RGB there.
Hydrogen nebulae around LBN438 is much easier to show now.

Hey Dave,
Thanks for this data! I've been out of the loop for a while, but this was good fun. I hope to get my own data again soon. Here is your image.

It's amazing. You guys have all done an amazing job with this data. I envy all of you.

Thank you so much for taking my hard work learning this ASA system and turning it into something worthwhile.

It would have been a pity if this data hadn't been processed to the extent you guys have done.

I look forward to the day I can do this on my own...but heck, baby steps right? I have to learn to capture the data before I can actually process it!

You all have my gratitude.

Hello Dave,
I wanted to revisit this project by changing a couple of workflow steps and masks I was using. This image has been fun to work on since there is no neutral background and the large stars. Stretching the image to bring out the foreground nebulosity without blooming the large blue stars have been the greatest challenge.

Congrats to Dave for getting this image in Astronomy Magazine this month!!!

Dave did you do the processing or was it someone from the group?

Saw all the hype and decided to throw my 2 cents into the processing! Congrats on getting into Astro Mag!

The central lane of the cloud is awesome!

Thanks again for the data availability, Dave. You have equipment that most of us will never have access to and it's great to be able to learn on equipment of this calibre!

I thought I had introduced some chromatic noise into the image until I saw Yuri's upload highlighting greater HA data. Nice to see I was on the right track all along!

Here's my 1st run at it and processed in Pixinsight. The URL is provided because the board software thinks I'm attempting to attach an image.

Things to fix:

1) Create a better luminance mask to further highlight the central cloud structure
2) Eliminate the low SNR located in the top left
3) Ease up a tad bit on the AtrousWavelets
4) Possibly clip a tiny, tiny bit of shadow.

That someone would be Yuri. Check out his flickr page, it's incredible!
