Hi Mike,

Quote:
How long did you record for with the DMK? How long did it take you to swap in the ToUcam? and how long did you record the colour data for?
A minute for each, DMK @ 60fps, Toucam @ 15fps. It takes me about 15 seconds to swap the cameras, I use a flip mirror, with one in each eyepiece hole. Then quickly set the focusser (I have a moonlite with the stepper motors on it so can quickly move between positions, bought right here in the classifieds section).

Did you have to rotate the channels to match them up or did you ensure the cameras were oriented the same way?
Because of the flip mirror I had to flip the colour channel horizontally, then rotate by about 3.5deg in PS, then they aligned pretty well, possibly could use Registax for this later on. The colour doesn't have to match super well +/- a pixel and you won't notice.

I did the same thing when I first got my DMK - captured luminance with the DMK and colour with the ToUcam. It worked well until I got the colour filter wheel. It gets quite frustrating to have to swap cameras, refocus etc, especially when you've got a short period of time as with Jupiter.
That would annoy me too, as all the avi's would be different orientations etc. I already had a flip mirror, so it was a no brainer for me. Next step is to see how long the colour lasts. Can I take a colour avi, then several mono ones, and still use the original colour?

Cheers
Stuart
