Eta Carina and The horse

[johnnyt123]

Hi guys..

Here is my first real take on LRGB imaging.

I first started imaging the Horse Head about 6 months ago.
Started with RGB. At the time i didnt know anything about different filters having different focal lengths and the result as u can see are swollen stars and the colours not quite lining up.
RGB data was only 5 min for each channel
Ha data was gathered a couple of weeks back for a total of 2hrs.

The result image is composed as follows:
Luminance is HaRGB combined all in greyscale.
R Ha
G Green
B Blue

I also had a quick go at Eta Carina
Ha: 45min
RGB 15min each
combined as:
L(HaRGB), R, G, B

Focus was better this time round but is still an issue that needs to be resolved

Any advice / Criticism is welcomed.
thanks for looking

Johnny

Ps: The colours for the Horse Head Nebula look off, possibly due to the upload compressions process.

Good images there John :thumbsup:

Carina is a bit brown to my eyes, not sure how you would fix that. The HH came out well, as you say colours a little off but love the detail you've got in the curtain!

Cheers

Thanks Jo.

Yeah you are right. Both shots are a little brown.
I will have to play with the colour tone to adjust them.

Try dropping the greens a bit and see what that will do.

Cheers

When you add luminance to a reddish image, the result is a salmon colour. There are tutorials around for restoring the correct colour balance with LRGB imaging, though since I don't do this myself I can't point you to any sorry, but that is why they look the way they do.
