This cropped shot taken with the 40mm at f20 really shows well how the homebrew caK filter is picking up the proms in this image. What looks like the spicule layer in Ha is easily visible, along with numerous prominences. I'm really looking forward to exploring and hopefully improving the capabilities of this filter as the year progresses, it's going to be am interesting one!
