NGC 6188 HaRGB

[Stevec35 (Steve)]

I hope I haven't committed the over-processing sin with this one because it's very tempting with all that nebulosity. Anyway, here it is.

Cheers

Hi Steve

There is a strange mesh pattern over the whole image
Not sure if it's a result of the debayer process
you might also want to save it in a format that has lower compression to avoid compression artifacts

The data is excellent but I think you've overwhelmed the red channel during the Ha blend. It lost all its dynamic range. Worth a repro IMHO.

Thanks for the feedback Marc. I'll have a look at it.

I don't understand this comment at all. It's not a colour camera so debayering is irrelevant and I don't see any mesh pattern. Also it's saved at Jpeg grade 11 which is not very compressed.

Steve...humm colour is all over the shop on this one, cyan mono-chromatic stars, burnt out reds.

That said the field is awesome...and inspires me to to dust off my FSQ.

I suspect the data is very tidy indeed, just needs a more subtle brush-up

Thanks for the comment Peter. Looks like I screwed this one up. Everyone don't look until I fix it up.
