Hi Mike,
Congratulations on your article. After reading it following came to my mind based on an approach made by Edward Roach from USA
You describe the Pros ans Cons of each camera type in this case Monochrome and one shot color
¿ Why not get for example one DMK 21... and one DBK 21.. instead of a filterwheel ? Shoot the same object one time in BW and then in Color and combine those images ?
The cost of a BW and a Color camera is less then a BW with a filter wheel
The focus point of both cameras is 100% parfocal. They really come well adjusted from TIS.
The Pro is you do not have to fiddle around with registering the 3 RGB AVI's.
I made once Saturn and this came out
