Default ASTRO: M42 - First LRGB Effort - Man, this is hard!

I literally spent the better part of a day working on this LRGB of M42.
Original exposures were L: 10X60s and RGB: 10X60s each. In the end, I had
to add a separate Lum layer at 50% opacity to more correctly address a color
imbalance and add detail at the core w/PS CS2. I could not separate the
Trapezium because I was already maxed on the white level stretch Log(x). Is
there a way to resolve this issue?

Anyway, I'm still practicing.

Cheers,
Scott Busby

Hi Scott,

I would say that you had a very successful first LRGB effort.

Regading maxing out the white level in the core, what many people do is
feather in the core (using PS) from a separate image (or images) taken with
a much shorter exposure to avoid saturating that part of the image.


Regards,



Jon Christensen

This website explains how to do just that.

It looks like you did pretty well. Your shot has very good definition.
