Description

Compare this image with the one of M101 taken with the same scope on June 21.

This one integrated 60 minutes of light with the 178MM monochrome camera binned 2x2, while the other integrated about 40 mins of light binned 1x1 with the 385MC OSC camera.

Albeit the color camera image was taken with new moon and the monochrome one with almost full moon, it looks like the performance, sensitivity wise, is quite close between the two cameras.
