Thanks,

Very nice Don, that 7nm filter works well and seems to enhance the detail.

Nice captures Don, is there a big difference in sensitivity between the two camera's.

Nice captures Don, is there a big difference in sensitivity between the two camera's. Thanks, John. The basic sensor in each is the same, but the color has a Bayer mask to produce the primary colors. So, it's sensitivity is reduced about 20% from the mono. In use it isn't really noticeable. For an exposure of 30 seconds in mono, you might have to use another five or ten seconds in color. You may even be able to increase the gamma slightly to make up the difference. The object you're viewing and the seeing conditions have a larger impact on exposure. The use of the narrowband Ha filter does increase the exposure time noticeably, but it's worth the wait. In any case, both cameras are very sensitive and work nicely for near real time viewing. Don

Thanks Don for reply, you explained it nice and simple just what I wanted to hear without going into quantum efficiency percentages and so on like they do on the some manufactures websites. I just loose it when numbers get involved
