Any Astrophotographers from the film era still around?

I have been looking at Takahashi schematics and one item that features a lot is the Mamiya 645 Camera. I notice Takahashi also has a few adapters for this particular camera

Were these the ducks guts back in the film era...the choice of season professionals...albeit an expensive choice?

Why? or was this just big in the Japanese market?
