Hi Mick
I find that there is a noticeable difference in “image brightness” on the screen between my DMK21 mono and DBK21 colour.
I like to use the DBK21 colour for colourful double stars, but some of the doubles and their components are so dim that I often have to change the DBK for the DMK just to get an image on screen.
Also, I have noticed a marked difference in “image quality” between the DMK21 and DBK 21 when viewing Jupiter in mono and colour respectively. The DBK colour image looks very grainy due to the high gain required to set an exposure of say, 1/15 to 1/20 sec at 30fps whereas the DMK21 mono looks much smoother as the Gain need not be as high to achieve the optimum shutter speed and frame rate.
If I wanted to specialise in high resolution planetary imaging, I would go DMK plus colour filter wheel and colour filters. However, as more of a space tourist, I am happy to accept the limitations of the DBK to produce images that meet my requirements and satisfy my personal goals and standards which attract me to this wonderful hobby of ours.
Cheers
Dennis
