IC4628 Prawn Nebula 29-31/8/16 Narrow Band False Colour
« on: 2016 September 06 00:53:43 »

I have been using Pixinsight for about 5 years now mostly on RGB images and then HaRGB before recently taking the plunge into narrowband imaging.
Image details are as follows:

127mm APO,
ASI1600mm (cooled to -20c)
Resolution: 0.82"/Pixel
Baader filters.
Ha 7nm 3hrs
S2 8nm 1.5hrs
O3 8nm 1.5hrs
(All 600sec subs)

Processing Brief:
Mure denoise
Histogram stretch
SHO-AIP Script to construct luminance and combine into final image.
Endless tinkering to get colours as near RGB as I could (at least to me?) but I think the red intensity is reversed!!!
Tried various methods to equalize star size of S2 and O3 but ended up masking and desaturating them.

All comments welcome ...especially on palette selection and star correction.;topic=10177.0;attach=12197;image

You have brought out some lovely detail in that one.

For me - if you are shooting with NB filters then I don't see the reason to spend so much time trying to make it look like an RGB shot.......but final colour is always to one's own preference. Just as with opinions....we are all different.  ;D
