I have never heard of cv Yatagai-miracle let alone Sano tokunow kabuto. Is this just me? CV are being created faster than I can memorise them.

The flower really is something else though. Very distinctive from SK IMO.

There are around 300 asterias cultivas in Japan.
Mr. Yatagai developped his miracle kabuto.
Mr. Sano developped his tokunow kabuto.
The plant in the attached photo is crossed these two plants.

I think each person has different opinion for the pattern of super kabuto.
The original super kabuto was found by Mr. Takeo in 1980 from imported asterias. It was a monstrosa with large white fleckings.
Since it was just one plant, crossed with many asterias later and so the current all super kabutos are cultivas.
You can adjust the degree of fleckings by crossing eg A and B.
Some persons may look at special flecking pattern eg C.
I like a super kabuto with thick fleckings eg D.
I think fleckings of the super kabuto with flowes, attached on forum yesterday was not thick enough.
A:Very thick flecking super kabuto (Megane hakuten super kabuto)

B:Nudum (Ruri kabuto)

C: Tiger super kabuto

D: I like this degree of fleckings

Really nice plants Hanazono and some interesting info thanks.

Yesterday morning was cold, temperature went down to 3 'C.
Asterias are continuing to open flowers.
The flower in the photo is large, around 10 cm diameter.

Beautiful as always, mate. Your astrophytums have got to be among some of the best that I have seen.

Some Mammillarias added flowers yesterday.
