just... WOW!  

I haven't had a chance to play with my Scorpion since I "had to" go to a conference in Tuscany last week.  But I hope to get some more chances to try it out in the weeks to come.

Hi Milton,

The image does use data from two different movies at different  

exposures. The surface exposure was 2.39ms/ gain 455, the prominences  

33.33/ gain 572. The prominences were recorded in the surface  

exposure, but not well (or I haven't figured out the right way to  

liberate them yet...)

more time for experimentation and less clouds needed!

Hi Alan;

So is that a movie in 16 bit mode?

Or is it a stack of two movies at different exposures?

I'm still wondering if you expose it properly, can you image the  

suns granulated disk and still capture the fainter limb prominences  

in one image / movie?

Thanks in advance..
