NGC6188 Bicolour Narrowband Processing Challenge

[Atmos (Colin)]

Started back from scratch again and had the aim this time of toning down the excessive processing, think I got a much better result. Still wanted the green obviously

great, i'll have a crack tonight Lee


would be happy for more people to post data in these dark times of Cloud.

I thought I'd give this a go to, processed in StarTools with Ha as red and Olll as blue with a synthetic green.

I tried to give it a bit of a gold and blue look with contrast between the creamy gas and jagged edges of the dust clouds.

Thanks for looking and for providing the data, it was a lot of fun.

Cheers
Jo

Nice one Jo, love the colour; I think this is my favourite one yet

Good stuff Russ. I'm happy to keep posting my data on the rare occasions I manage to get anything. It'd be great if Astrobin's public data pools were free to submit to, but I understand why it's not, given the cost of hosting potentially very large data sets.

uploaded to flickr as well as not sure how the compressed version will go (note i couldn't get it to upload)
.
it also may be a touch dark as i processed on the tv.

Nice one Russ! I was trying for something similar the last time I was playing with this data but couldn't quite get it. Did you process with PI? If so, can you give me a quick run down on your process?

Cheers Lee, I just quickly made a less dark version on the work computer https://www.flickr.com/photos/803366...blic/lightbox/ - its not great as the file size was tiny but a bit more like what I was after. Got to say it was a treat using such nice data, way better than dslr.

Unfortunately I haven't got PI as yet. This was all done in photoshop, I didn't worry about sharpening or masking just tried to get the colours to be diverse. So opened all the images up and created duplicated one of the files. then copied the other image and pasted as a layer. merged them with the ratio being slightly more of Oiii (as its fainter). Then converted mode to rgb, pasted the Ha into red and Oiii into blue (the blend remaining in the Green channel).
from there I tweaked with selective colour' probably did a lot of iterations, similar to how it was done in that other link I sent you the other day. hope that helps somewhat - sorry I can't help with PI.
