Thanks for the tips. I thought the exposures had to be similar in order to get accurate 

color. Obviously that isn't working for me :)


I will do that the next time around. I am very familiar with Photoshop and had played with 

the channels quite a bit. But with either red blown out or blue barely existent, there was 

just no saving anything. In fact, when pushed (or pulled) that far it does some whacky 

things (especially to the saturation).


Now I know better, I can shoot better. I'll give it another try. Looks clear tonight, I wish I 

could go out. Maybe I'll try tomorrow.


Wish me luck (I'll earn the skill later)

I am trying to shoot with this B&W camera, and I must be doing something wrong.


First off, I am having a lot of difficulty trying to get an exposure that will work with all 

three 

colors. If I expose the Red properly, the blue is non-existant. If I expose so the blue 

shows 

ANYTHING, the Red is blown way over-exposed.


OK, so I shot a few Mars shots and I stack them up. These are straight from Astro IIDC 

and all 

three shots have the same camera settings. Put the red in the Red channel, Blue in the 

blue 

and green in the green. What do I get? A very mucky red color that doesn't show any real 

white or come close to the colors I get with color camera.


This time I did shoot  through an IR filter for all exposures.


Am I missing something there?


Please help me before I send this camera back for a color version :)
