Here are the Saturn images from 21st April 2015...we continue trialling the
new ASI174MM camera but we have been hampered by cloudy weather for quite
some time, preventing us from getting enough "hands-on" experience of the
camera's full capabilities.
I had to employ contrast reduction during processing to reign in the
histogram even though we only set the histogram during capture at 20% for
blue, 23% for green & 26% for red...running at 198FPS for the captures
earlier in the night & 132FPS for the later captures...I think we can
definitely say it is certainly a very sensitive camera!
