Go down the thread you will discover that these big guns are for astro-applications actually. I don't know when the photos were taken but it seems that it was not very long ago as I can see a Pentax DSLR had that kind of lens mounted (a K10D or K20D, see the picture below). It is good to learn that if Pentax is still making those astro-telescopes and lenses which is just great! :-)
