I observed these tonight and confirmed them without knowing the PA, and my estimated PA was very close.
STF 2482 m1=9.0 m2=10.2 Sep=1.8", PA 341 deg. Used 173x and 243x on a 6" f/8 triplet.
STF 2488 m1=9.1 m2=10.0 Sep=1.8", PA 352 deg. Used 243x.
STF 2482 was more difficult than 2488 in my estimation.
