CaK Proms 22nd July

The double limb is nearly resolved into individual spicules and takes on a feathery look in this image take with  the homebrew CaK filter with the 40mm scope at 700mm focal length.  In addition a large prom was also visible in almost ghostly form.  This is a 'one shot' with both disk and proms being recorded simultaneously in the same exposure with the DMK31 camera.  Hopefully in the next week I will be able to pick up a new scope to allow me to run at a native 60mm f10, which should do a nice job of revealing a bit more detail in the double limb in particular.
