Tamron SP 300/2.8 LD IF?

Wondering if anyone out there has experience with
the Tamron SP 300/2.8 LD IF (manual focus) lens for
astrophotos. MTF numbers on seem
respectable enough, especially at the edges and
corners. I saw some nice images posted by Andrew
in July. Any suggestions for stop-down (wide open?
F4? F5.6??) or UV-blocking filters for this lens?
Thanks, - John B.
