CaK Jets Animation - 9th March

It really did amaze me how easy it was to observe the prominences and jets in CaK wavelengths with the latest incarnation of my filter, and it also amazed me how fast they appear to move in these shorter ultra violet wavelengths compared to the usual hydrogen alpha views of the chromosphere.  This animation is just 5 frames and represents a real life time frame of just about 2 1/2 minutes.  This was taken with the 100mm Tal refractor with a Beloptik tri band ERF, homebrew CaK filter and DMK31 camera imaging at f20.
