Its got a lot going for it. 85mm or so backfocus makes it easy to handle with filter wheels etc. Its quite sharp and is clean wide open. I like it a lot.
Its also very nice as a terrestial lens with nice bokeh and easy to use focus ring. Adapters are cheap as chips on Ebay. The 55mm Pentax though is not as good but pretty good binned 2x2 as seen here:

Of course the cream of the Pentax is the 67 300mm F4 EDIF. Phil Hart won Malins last year with a shot using one of those and I am sure we all remember Marco Lorenzi's stunning widefield shots with that one. Kind of rare and expensive, it often sells for US$1950 on Ebay and does not come up much. The cheaper and more plentiful 300mm F4 (non-ED) sells for around $450 or so and is also sharp.I haven't used mine much but as I recall it was coma free wide open (F4 though). I think it would be good for narrowband widefield.
