At least Brett above understands the words used for NB processing
No Nii data.did she do this for the nii data ?
I agree Bob, Carole's data and process is very vibrant. Yobbo's process is very beautiful too.bobharmony wrote: ↑Thu Jul 02, 2020 10:35 pm Cara, I was happy to see your efforts with the data. When I did the Ha->R, Oiii->G, Sii->B combination the result seemed a bit over colored to me. I worked to tone it down a bit and will put that version up when finished. Looking at your results, I begin to think the vibrance is in the data, and not in my process.
Thanks for throwing this out there, it's nice to work with NB data for a change.

For those who don't know how to combine filters, you add them to the relevant channels. In this case I created a new image from one of the files and converted it to RGB, then pasted the Sii into the Red channel, Ha into the Green channel, and Oiii into the Blue channel to create an SHO Hubble palette image.
With narrowband you can do what you want really, some like to do HOO (Ha into Red channel, and Oiii into Green and Blue.
I use Photoshop CS3.What software do you use to produce the final image from the NB files?
Very nice process Bob!bobharmony wrote: ↑Fri Jul 03, 2020 3:50 am I went back and loaded StarTools up mapping Ha to R, Oiii to G and Sii to B. I also added the Ha data to the Luminance channel. This time I really pushed the deconvolution module. I backed the colors off a bit from what StarTools came up with. Here is the result:
I wasn't able to do anything useful with the downloaded RGB file so have not tweaked the star colors at all. Great fun! Process was Crop, Wipe, Develop, Color Deconvolution, Corlor again, and some noise reduction.

very nice i like the last one, chft pallet ?carastro wrote: ↑Thu Jul 02, 2020 8:42 pm OK Guys, sorry I didn't get back sooner with replies to all your questions.
As discussed with Graeme when I submitted the data, I did bin the Oiii and Sii and also combining the Ha 3nm and 7nm I simply stacked each separately and then stacked the stacks in Ha.
However I thought it would be a bit much to submit binned data "as is" so I registered all the filters to each other before uploading so you didn't have to mess about, especially if some of you don't have the software to do that. I didn't supply the fits files, just the already stacked and registered files for the same reason.
There was no noise reduction applied during stacking. The binned data was resized by the registering software (Registar) but not drizzled, though now you come to mention that I might even give that a try next time.

Some-one asked to see my original image, and I did more than one version.
This was an HOS version (Ha in the Red channel, Oiii in the Green Channel and Sii in the blue channel)
This was my SHO Hubble Palette version:
and this was my final version where I also added someRGB stars into the mix, but I don't think I gave you theRGB just for the stars as I thought that might be a bit too much, indeed it has taken me a number of years to work out how to do that.
