Tarantula Nebula HaOIIIRGB

[Atmos (Colin)]

After many many many revisits I think I finally have this data set (well two) where I'd like them to be.

Telescopes:
RH200
Sky Rover 130mm

Cameras
QHY163M
Nikon D810

Data
70x300" ISO400 (Sky Rover)
Astrodon 3nm Ha: 44x300" (RH200)
Astrodon 3nm OIII: 60x300" (RH200)

There is oh so many ways of combining narrowband to RGB and depending on how it's done changes the way both Ha and OIII colours turn out. Even the order of some steps changes the colour balance. PixelMath is my friend, it's a good friend that sometimes turns around and slaps you in the face

It's always a hard decision of whether or not to resolve the core of NGC2070 but I decided to keep the dynamic range. It is a little brighter than I'd originally wanted but it does look too flat otherwise.

Pixel Peeping Link for those who you who like surfing around the knots

A lovely field of view, nice crisp detail and bold colours

Was fun exploring the high resolution version, noticed some vermis though and now I want to go

BOOM! That's got some punch alright - a bold presentation indeed

Bold and punch is right up your alley
Reduced the green in the OIII emission now too. Did a little reading and from what I can find the OIII emission (500nm) is more on the blue side of cyan than the green. Not by a lot.

Cool Colin, looks like a colour negative.. or even a bit of a hologram

Very cool palette. Looks like the Vela SNR.

It packs a bit of a lunch Mike

Thanks Marc, it’s like vela but less stringy

That is a huge field of this oft imaged target. So many interesting things going on there. Plenty for me to image yet within that field. Colour looks great Colin.

I know what you mean! I’ve just got myMewlon 250 up and running tonight so there is a lot of spots in and around the Tarantula Nebula to image at longer focal lengths.

A bold and splendiferous wide field image to be sure You are doing well combining all of these different data sources Colin. Nicely done.
