Duane:
My first guess would be that the filters don't block the IR, and that's affecting your green
and blue images (the blue, in particular, shows more surface features than it seems like it
ought to). Can you put your IR blocker in front of the filter wheel? Or on the adapter in
front of the camera? That way, it'll be in place for all your color settings.

OK, I tried the new B&W Firewire camera this morning. First light (yay)
I need some more time using it. This morning was pretty quick and dirty.
However, my question today is, why are my colors not turning out right? I did RGB
through
the Apogee filter wheel and the image comes out like this:
http://groups.yahoo.com/group/Astro_IIDC/files/Planetary/Mars1.jpg
All the images were shot one after the other, the only change being the flip of the wheel.
In a new photoshop image I placed each one in their corresponding channel. Not until
after doing this did I sharpen.
What's up with this color?
Also, is it normal that each of these colors have a little different focus? This particular
image I didn't adjust anything (just took the shots). But I noticed on subsequent images
that the filters had a different focus.
A big peeve I have of this filter wheel is the threading. It does not match the standard
filter
thread. I have an IR filter I wanted to put in the fourth slot and it won't go. I looked at
the
threads on the included filters and compared to my IR filter and they are not the same. I
didn't use IR on any of these.
Any ideas on what I'd doing wrong? I took several shots and even have a very sick
looking
Saturn to do with my ill Mars.
Thanks for the help.
