Subject: Re: Unibrain Adaptor
It may be my filters or the way I exposed a few of my shots. I have gotten some OK colors
on my recent attempts but none of the shots are very clear. Probably seeing conditions but
maybe focusing issues with the setup I have when using this camera (?). Camera>Cmount
adapter>IR Filter>Barlow>Filter Wheel>8" LX200.
Alan posted a color separation recently and I took his R, G and B and put them in their
perspective channels in photoshop. On my system, it was green at first but with two quick
adjustments it looked great. I took the L and loaded it as an alpha channel and in a new
layer used the selection to add in the black information (opacity set low). I used the
selection again to boost the bright area contrast with curves and then inverted and
boosted the dark area contrast separately. It was a lot of fun. It's easy when the images are
as great as Alan's. I think I've got the color channels mastered but my images are just
"mushy".
I'm having more fun with the unibrain. It's so much easier —Camera>adaptor>IR>scope.
The only tough part with the Unibrain is finding the darn planet. It's sensitivity is so much
lower that you need to be close to focus to find the darn planet. I watch the numbers
(sharpness) to locate it but the DMK is way easier in that way. I can also barlow farther
with the DMK which is nice.
I am going to try the color version of the DMK and see how well it works out. If my results
are better than the unibrain and the sensitivity is an improvement, I'll be very happy with
it.
It doesn't sound like anybody here has the color version of this camera (?). I might as well
fill that gap :)

Hi Duane;
Well the camera does like you, as you did take a nice Saturn shot
with it.
I still think your main problem is with the color filters and color
mixing, which can probably be solved if you try shooting terrestrial
targets. That you can see what real colors look like with your eyes
and then makes them match.

You guys hit the nail on the head! I'll bet that's my whole

Hay Tim, how much was that Flea? They don't post their prices but
it looks pretty cool.
I'm 20 days into my 30 day evaluation on the DMK camera. I'm
probably going to send it
back as I'm frustrated with it (and its probably not its fault). I
might try their color version
or I might switch to another camera. The DMK is $590 if I keep it.
Yea, that camera doesn't like me. My Unibrain likes me. He's my
little buddy.
