Description:
The problem was not in either locating this or splitting it, but the
secondary was so faint it was hard to pick up. I finally spotted it
with 120x. I tried the MicroGuide EP, but could only do rough
estimates as the illumination of the reticle washed out the 2ndary. I
got about 150” separation, and 180 PA (published 142”, 189d)
This was enough to confirm that this was the secondary.
