Orion nebula with Quattro and 1000D

Recommended Posts

I've never really had a proper go at the Orion nebula, but since it's above the house now at a good time in the evening I thought I'd give it ago. Still can't seem to get the colour balance right with the modded dslr and Astronomik CCD-CLS filter, it still looks a bit too red in my opinion.

This was 2 hours worth of 5 minute subs at ISO800. 20 x 15 seconds for the core.

Full spectrum 1000D, Quattro 8s on an EQ6. Processed in Photoshop.

If anyone has any advice on removing the red cast I'd greatly appreciate it!

Thanks for looking,

Carl

looks good to me, if you want to lower the red channel a little, it should be easy in photoshop using either the colour balance or selecting the red channel and lowering it a little with the sliders in levels or curves, look at the histogram with all channels selected and you`ll see if the red is overdone

I think your picture is fantastic the way it is.

I've seen a lot of renditions on Twitter lately where people are using this colour approach.

It really lends itself to detail, and your image has tons of that 🙂

By red cast do you mean the red in the background? 

To my eyes that's how it should but with the dust..jet black to my mind isn't quite right, and they say clipping the blackpoint destroys quite alot of your hard earned data..

A job well done I'd say..

I think the colour is spot on.  I'd leave as is personally.... Lovely result.

I opened your photo in photoshop and in Levels i chose the red chanel, I then moved the middle slider to the right a bit.

...thing is there is still Ha signal in the background across this image so it kinda should be red!

Played around with contrast and sharpen.

I hope that I am not being rude by posting these, your data is excellent.

Thanks all, I thought the darker dust seemed a bit red and the stars also seemed overly red which made me think there was a red cast to the whole image. Most images I saw the dust was more of a chocolatey brown colour.

@Singlin I think your first post is similar to what I had in mind. I've been playing with levels and colour balance a bit more last night and I think I'm happy with this for now.

Yes the last version is better. Truth be told I thought version one was perfectly fine but now that I see the new version, it’s better 👍🏼
