I have uploaded FITS data for two of my recent captures, if anyone wanted to practice and also to show me the ropes! I will put up my own attempts soon as well
I cannot get NGC 6188 to stack in CCDStack, PI or DSS - all 3 fit files are different dimension sizes and I cannot even manualy align them in CCDStack.
Lewis!
You have to do a star align first.
With PixInsight i did a StarAlignement
and afterwards with ColorCombination the 3 Images Combine nicely to a Color Image in PI...

CCDStack wouldn't align them, even trying manually. Kept rejecting them, and when I flick through the files after trying, definitely not aligned at all. DSS outright rejected saying incorrect frame size etc.
I will try again in PI.
EDIT - tried again in CCDstack with a common crop to all to make same size, and still refuses to align / register them Odd - never had that issue previously

Nebulosity3 does it without a hitch
(I think you might need to scale them to match each other )
Lewis,
Would you mind listing the steps you took? As yours came out much different to mine.
I do an RGB combine in CCDStack using SII for R, H-a for G and OIII for B. This gives a GREEN image. I then put it in Photoshop and selective colour transform it, altering magenta, cyan and yellows predominately.
Hi everyone,
Wow so many responses! Thanks alot for your input everyone some very good attempts and interesting to see how different the colour palette has come out.
Gerald your image looks almost like a real RGB!
Hobbit, your link comes up as a very small image/icon. Have you got a link to the full size?
Jo thanks for trying your hand at IC1805, yes the data really is quite lovely perks of hiring a very expensive set up for a short period! What software did you use? I liked the soft diffuse effect you added to the stars
Lewis, I normally edit the three NB channels in startools independently and then stack/RGB combine them in PS right at the end, so never tried aligning them in software (though would make my life much easier, must try CCDstack sometime ). Would you still like me to put up the un-cropped images? My favourite version is the hubble-esque, probably a mid point between the two green adjustments.
I am struggling to extract the Ha data from NGC188 from the background in Startools, anyone got any hints or tips? Thanks again everyone!
I've added a link to the stacked FITS for the Tarantula neb in my original post, if anyone wanted to try their hand at that Here's my very rough attempt using the Ha data, using just the basic stretching tools in DeepSkyStacker
