calcium foam

[Kitsunegari]

interesting instantaneous feature look at the red arrow in top left.

    LEarning to process a calcium animation is interesting.  10 second cadence is clearly way too long.   The surface changes so rapidly i think 1 second between captures is proper.

An interesting image.

Cracking animation! is that a transitory pore opening up and disappearing? what was the timescale?

The above capture was about two minutes elapse time. 

 

The surface in calcium clearly re-develops extremly fast , faster than i imagined in fact; especially when compared to hydrogen alpha.

,  If you watch my longer timelapse below ; this represents 1 second intervals (5000 frame capture @ 500fps each video x 100 videos).   

 

I think zero delay is the optimum choice for this wavelength if you want to clearly capture something on the surface before it boils away.    I am anxious to perform proper processing out of high resolution with a 4000mm recording ,  I may invest in a 4x powermate for this; or have a special barlow developed.
