New solar CaK filter stack

I've recently upgraded the Omega (four filter) CaK stack to include a Baader CCD (Blue) filter as an ERF. I also added a SkyBender filter tilter - to bring the 2A filter closer to CWL.

Been frustrated by the weather - if not rain then thick cloud...
Well, this morning there was thin high cloud so let's give it a go. Mounted on the ED80/HEQ5, with the ASI 174MM - Success!!!!!

The video files (to be processed ASAP) clearly show the current sunspot groups and large areas of bright flocculi.
So far so good.
Onwards and Upwards

If you haven't viewed the Sun recently now is the time -AR 713/4/5 easily visible! https://www.raben.com/maps/index.html
