Subject: Astro IIDC dark frames  and "Use Sharpness for Capture" issues


In the manual Milton states that Dark frame subtraction is really only 

appropriate for 1 sec exposures or longer. Does this mean that I should 

just forget about making dark frame movies for Planetary imaging? I 

suppose I should have the box checked for automatic hot and cold pixel 

subtraction, assuming my MacBook is fast enough (you mention the CPU 

load).


Also I notice that if when capturing images of Saturn I don't seem to 

be able to "Use Sharpness for Capture" option. The movie starts but no 

frames are captured, implying that nothing "is good enough" for the 

software! I am using the default settings. Perhaps you can advise.
