Hi Andy,

Thanks, but its all in the image processing… 😉

I am quite please with how it’s performed though. Certainly planning on keeping it in place for a while.

The single spot image shows the Wilson effect quite nicely but I think I went a little overboard with the wavelet processing with the faculae image, it’s a bit “speckley”.

Although not as narrow as a proper Ca filter I am quite impressed that it can show the faculae well and possibly some of the super granulation of the chromospheric network.

It’s quite a paradox that I’ve got virtually nothing when I’ve actually tried it on the comets I’ve been able to see but it turns out to be great for solar observing!
