I prepared all my solar toys this morning only to discover later that there were really few details to image. I started with some granulation in K line but I soon give up as eventually I didn't see any sense in this, particularly after Christian showed us his results
So, only a full disc, some small prominences on the SE limb (but not in detail because I noticed them only too late while processing the disc image) and a portion of the SE limb, all with the calcium Quark to which I replaced the IR-eater glass with an Astronomik IR-cut noting an improvement in sharpness. Of the original BF I left in place only the blue glass.

Re: Boring Sun
So incredibly quiet. Nice images, though, Raf.

Re: Boring Sun
Thanks Stu. Today's page of Spaceweather.com has an
interesting article on some consequences of this solar minimum, it's worth a reading.
Apollo, yes calcium Quark is heat tunable however the bandpass is large (5A) therefore tuning has only a limited effect. Tried to stack it with a Omega Optical CaH filter but images are too dark.
