I spent up until 1 am last night trying to make my data work..It cleared and I missed a good opportunity but the processing got to me...but at 1 am I gave up I was just not together... unfortunately....Startools gave me a green so bad that I could see it...I tried dropping the green channel but green is here to stay..clearly all the trees..today I tried and tried but this is a good as I could do..80mm RGB and HA 1600zwo mono eq6 mount Asiair plus control guiding etc.
I had a little ovcer 7 hours so I had hoped for much better, but the trouble is I can not control the colour...

Alex,
Sorry hear your having trouble with colour in ST
A couple of things first
1/ After stacking in DSS your not touching the RGB colour adjustments in DSS ?
Startools requires clean linear untouched data from DSS ( no fiddling ) just save stacked file as a fits file ready for Startools
2/ When using the Mono camera are you leaving the box “unchecked” in DSS > Settings > Fits Tab > Monochrome 16bit fits files ? You only check this box when using a Colour OSC camera
3/ When using a Mono camera are you loading your RGB and Ha data sets into Compose correctly under each channel ? Then selecting the correct compositing scheme ? You shouldn’t have to touch the exposure sliders on the right as ST will create a Synthetic Luminance file from your RGB data set weighted correctly. If you captured Luminance just load it in the Lum slot at the top and so on with RGB
I don’t think your issue is in the colour module , I tend to think it’s to do with loading your data sets into Compose correctly. Also understanding how Compose works. I’ve attached the link to Compose so you can determine what’s best for your data sets and where/ how to load them
I can think of a few more things regarding colour but that’s enough for now

Thanks Martin for trying to help.
I have read all you have said and I still have no answer..I never touch a stacked image in DSS, I load as required in compose....it is very simple...after processing in StarTools of course.
StarTools does say in the colour tool..you need to wipe..well I have ????
But there must be something simple I have "kicked" as recently my first M42 was as good as I could wish for...the second via the 80mm narrow band was green green green and it just was imposibblecto get rid of it....
I will go thru from DSS to StarTools again to make sure... I did one compose with no green or HA ..STILL GREEN AS????
It seems to be the new version that I am having problems with...
I think I will change to Pixinsite..twice I have applied to go on the StarTools forum and the first time ignored apparently and the second time said I would be contacted when approved but nothing...not even the courtesy of why or what happened...seems odd...it's not workng I so I think I will go over to PI....
I spent two hours non stop adjusting the colour one move at a time...altering the graph in minor steps just in case one had to hit a sweet spot.
As I said I was up until 1 am on this one object and tried everything that has worked in the past..the only reason I got this image image was thanks to photo shop really and a lot of time on it today...ran it all again from stacking to Startools checking stuff...
Thanks again...And I am tired wore out etc etc so I need rest I guess..things don't usually annoy me like this..probably not getting accepted on the forum is playing on my mind.

Hmm…..
When you load your DSS stacked RGB files and Ha file into Compose what Luminance Color do you select ? RGB Legacy ?
Also make sure Interpolation is ON
If your on the Startools forum , send a post and I’m sure one of the regulars like Mike , Jochen , Stefan will help
Even Ivo might spot your problem and offer a solution, he’s usually glancing every day
The ST forum has answered many of my problems over the years very timely , a great bunch of people on the forum
Alex, don't be too upset about the colours - you'll sort them out. (I would offer advice, but I'm not using DSS or PixInsight or any of the fancy programs...)
Take satisfaction (and some pride) in the fact that you have captured amazing detail. Doubly so on a target that is often very low to the horizon.

I have applied twice to join the forum ..the first time no acknowledgement of my request...second time months after the first I received a email saying that I would be advised...but nothing..nothing by way of acceptance or rejection....so no forum for me.
Here is a photo taken of the screen with my phone...you may notice the only channels loaded do not include green or Ha..yet it is rather green...

Alex,
I’ve written a procedure for stacking Mono data sets in DSS specifically for Startools, I just need to tweak it a bit and I’ll post it
Also I’ll write a procedure for loading Mono data sets into Startools via Compose including a rough work flow and using the Colour module
This is for benefit of both myself , yourself and other
Give me 24 hours or so and I’ll have it done
Don’t worry I write procedures all the time , I have 50 of them , I started writing them 5 years ago
Always glad to help
Cheers
Martin
PS I just thought of something, how do you know in your data sets that Red is Red, Green is Green and Blue is Blue ??
One can easily be mistaken unless you have a procedure , filters look all the same to me !!

Thanks Martin...I was thinking similar..but coming in they are all mono so emphasis may be different but nothing to give just a green bias you would think...in fact that last image I had Ha as lum..i was trying something and forgot to change back for the shot however when changed there was little difference.....but I plan to look again at my filters..everything really...
As someone who has nothing I would care to post here until I have more of a clue, I can only echo some of the comments already made in relation to detail. When you get this completed to your satisfaction - and you will - it's going to be superb. And it's not too bad now.

Hi Alex,
Here’s a few procedures for Deep Sky Stacker and Startools for you to use and see if it helps your colour and general processing
I’ve added some extras as well

Thanks Martin...I am sure it will help and also others.... and I am looking forward to going thru it all...
Last night for the first time in years I slept 5.5 hours straight then had a cuppa and slept another four straight..usually two hours is as much as I have before I wake up.then two more..max six all up.....and honestly I feel just so positive and happy ... I had fantastic fish on Turkish bread for breakfast and heaps of ham and salad ( flash pickled stuff that I prepared yesterday) for lunch and another nap so I am back as good as new...even my feet are not bothering me..there are but they are not jf you see what I mean.
And...ordinarily I would not have let that image get to me because as I have said it really is not about the result it is about just doing it...heck I should have just turned it mono and coloured it in and stopped carrying on like a pork chop.
BOM says clouds but it is clear...and the reality is that 80mm has a serious back focus issue..that what I should be concerned with....or my latest medical issues...good news get to go to Gold Coast Hospital...life is just so fantastic.
AND sorry to all for being a pork chop ...no excuses ...all my fault.

Thanks but surely my failures must tell you post it and live with it..
Your tag....you could change "Heroism" with "stupidity" and you have me summed up.
Alex,
I forgot to send is document on DSS Reference Frame and Groups
It should make understanding the DSS stacking docs a bit easier
Any issues or clarification let me know
Always glad to help

Thank you Martin.
It is looking good for tonight so today I will just eat and sleep and in any waking moments read your work.
I managed another good night's sleep which suggests that perhaps with the last sessions I pushed passed where I should go...but what do you do when you get decent seeing...sleeping thru it seems just plain wrong.
Thanks again and I hope you get a decent run down South real soon.
Alex,
Hope to get down South soon , definitely after Xmas, New year and January
I noticed you asked about how to reduce stars
Easy in Startools
Later on in your workflow either before colour or after just use “Shrink”
Procedure
Select Mask at top > Auto > adjust Filter Sensitivity to 1 > press Do
Then press Grow at top once , one click then Keep
Select “Shrink” then select “Keep Mask as is”
Make sure Mode is in “Tighten”
Bump up Iterations from default 10 to say 12 or 14
Stars should greatly reduce , adjust Iterations as necessary
If you have stars with big halos , increase Halo Extend to 3 to 5 pixels , increase Un glow Strength to 20% , increase Un Glow Kernel to 5 pixels
If your all your Stars are bloated or big you may have to Grow the Mask bigger to cover them , so Select Mask at top again , click on Grow once more again and press Keep
Then adjust Iterations again and the other parameters at the bottom again
Alternatively try Mode “Dim” but I find “Tighten” works best
When happy with result press Keep , then go into Mask at top again and select Clear then Keep again.
Shrink works absolutely unbelievable for my data sets
Thanks Martin..I have not tried increasing the number of iterations so hopefully that is the key. Generally I try not to change settings in StarTools so thanks very much for that tip.
Thanks again with all your help I now know twice as much as I knew before ..if you start with before representing all I knew...
You know there is a good case for living down South and visiting Sydney once in a blue Moon..or rather a Red Moon..if conditions are good that is...

Always glad to help
The key is not so much the iterations but more the quality of the Mask
A crap mask no matter how many iterations won’t give your good Star reduction across the whole image
That’s why it’s good to check your Mask after it’s created. It always flashes 3 times but you can check at any time
I’ve always used a Filter Sensitivity of 1 , default I think is usually 6 which misses out many of the smaller Stars
For me a Filter Sensitivity of 1 plus click Grow once usually does the job well
I’d love to live permanently down South and visit Sydney occasionally but my Wife’s and I are in two minds about it , we have 5 kids and 5 grandkids and they are always asking us to help out from time to time with minding grandkids , jobs around their homes , social stuff birthdays and so on ..etc.., I don’t want to be driving back to Sydney once or twice a week , it gets tiring
Maybe when they are all at school we will have some breathing space in about 2 years time
We do still spend about a total of 2 to 3 months of the year down there anyway but as far as Astro goes this year has been horrible ( for most of us in the hobby )
I do still enjoy the challenge that Bortle 7/8 heavy light pollution and blasting neighbours lights give you when imaging in Sydney, thank goodness for my OSC Duoband filters
Hopefully 2023 will be back to “normal”
Fingers crossed
...good news get to go to Gold Coast Hospital...life is just so fantastic.
