Tarantula Nebula NGC 2070 _TRY MY DATA

OK - it looks like another re-process will be necessary.

Maybe I should post the data & let others have a go?

Although comments and criticism allow to see own images from different angles, the final revision will be the one you like the most :-)

Sure - but I don't mind letting others have a go -
these Xmas holidays could be boring for amateur astronomers due to clouds
& they may like to have a go at some processing.

Notice Harel's post below - there is no way I ended up with those colours
even when I didn't mix the Ha with Red or Luminance.

I could post .reg pre-aligned stacks in tiff format ready to go.

What would be a good place to post them?
I don't like drop box as you end up with a program permanently running in your task bar.

Hi Everyone,
For those who are bored over Xmas -
I found Google Drive.
These stacks were saved as FITS then stretched in NASA FITS Liberator using x^(1/5).
They were then saved as TIFFS & registered & aligned in Deep Sky Stacker so they are ready to process.
Copyright - you can process them & post the result anywhere e.g
on Astrobin or flickr but give a link to my flickr photos saying that it's my data.
Have fun & I would love to see what the experts can do?

Here you are:

will have a crack when I get a chance Al, who knows it may sway me to go mono. I prefer the original by the way simply as it shows more colour contrast [more colours].

[alpal]

So that anyone with Photoshop can download my 5 files & have a go

I'll describe the whole procedure to at least get people in the starting line:

This method is quite good because it will almost automatically assign the grayscale images to RGB.


Open the 3 files :stack of red , stack of green , stack of blue.
Click on the red file.
Click on channels in the layers window.
Click on the right hand side down arrow button.
Click merge channels.
Change mode to RGB inside the little box that pops up.
Click OK
For Red select: stack of red
For Green select: stack of green
For Blue select: stack of blue
Click OK

Go back to layers inside the layers box.

Open the luminance file.

Go Ctrl A, Ctrl C to copy it.
Click on layers of the RGB file above & go Ctrl V to paste it as a new layer
on top of the RGB. ( Rename it Luminosity if you want to )
Set the blend mode to luminosity.


Now - open the Ha file called stack of Ha.
Go Ctrl A Ctrl C &
click on the now RGB L image & go Ctrl V to paste it as a new layer.
( Rename the layer Ha if you want to )
Set the blend mode to luminosity.


You should now have 3 layers in your layers window:
Ha, luminosity & RGB (if you have called them that )
now change the opacity of the Ha & Luminosity layers to taste.

( Note: If you want you can combine 50% of the Red & Ha together before starting the process.)

I hope that helps people to get started?
It's quite easy really & good practice for those wishing to upgrade to a mono camera.

Hi Slawomir,
OK - I'll try to re-create my original - but better.

I hope you do have a go & just in case you or others may
not have processed mono before I have included some easy instructions below.

cheers

I had a go at re-processing the L Ha RGB but
didn't really come up with a better one than the first.
Anyway I decided to see what a version would turn out like using only Ha as Luminance.
A larger version is on flickr 1920 x 1481 here:

Very Nice.

hi Al,

haven't had a go at mono data before (except b&w only).
here's my attempt https://www.flickr.com/photos/803366...ream/lightbox/
i didn't spend a lot of time on it but it wasn't as time consuming as i thought it would have been (for the steps i haven't done before). All done in PS.

Still liking your original version.

Cheers

Rusty

ps i edit at home on my tv screen then usually check the brightness / balance at work as the tv usually makes it appear brighter than it is - so it may be a tad dark.

Hi Rusty,
That's amazing for your first go at mono.
It's not too dark.
I got rid of the bleed line from the top left hand corner star with
the spot healing brush.
Can you do noise reduction masks?

it was made easier seeing what you had done with the same data. it would have been much less vibrant if i hadn't referred to yours.

thanks for the link, i had seen that before but i was probably in my photoshop infancy and it was forgotton, i would usually do colour select or something but the inverted background looks waay quicker. so actually - that channel has a few things I should start doing!

cheers,

Rusty

Hi Rusty,
You did well.
I think I have finally come up with something I can live with.
I took my re-processed Ha LRGB pic & combined it with 50% of my last Ha RGB pic to get this:
https://www.flickr.com/photos/24719437@N03/15429377843/

It adds a little touch of blue & takes some of the noise out of the background.
