Subject: Re: [Astro_IIDC] double hump histogram question
Which version of Astro IIDC are you using (4.01.01, 3.2.3 4.02.00 etc)?
I'll also need to see your movie text stack logs too, OFF LIST, sos end them direct to me.

We've been doing a lot of photography of Saturn lately and although
we usually get a single hump histogram after image analysis, we often
get two humps with a large distance between them. We proceed to slide
the confidence lever anyway to get a portion of frames to use for
stacking and usually everything seems OK in the final processed image.
I wish there was a way to see what the images looked like that were
analyzed and wound up in the "little hump". I suspect that passing
clouds dimming some of the images in the movie frame are involved.
Also we overexposed Saturn to bring up the intensity of the moons
nearby but Astro IIDC will often say "cannot stack images. Perhaps
something is wrong with the parameters we are choosing. Obviously these
deep images have Saturn completely saturated to white with fuzz around
the boundry.
