Better weather today, but no Ha or White Light...
A couple of CaK images showing AR2758 just about to leave us.

Hi Ken,
What scopes did you use to take these images?

[Merlin66]

Eris,
I have three ED80 refractors....
White Light - using the Baader Cool Herschel wedge with Continuum filter.
H alpha - using a double stacked SM60 filter up front and Coronado BF15 filter.
CaK - using a CaK, DIY construction using four filter elements (!!!!)

These with the ASI 174MM and the ASI 1600MM (with a x2.5 Powermate) seem to work well for me, in the seeing conditions I get down here on the Bellarine.
Use FireCapture, AS3! Does most of the basic processing.
