still don't quite believe it myself, but there was at least 58-degrees or more available from the Barlowed Plossl. Maybe it was an optical illusion due to extended eye relief.

Take daytime images using a phone camera through the eyepiece with and without the Barlow.  Just make sure the camera lens is at the correct distance such that the field stop pops into view as a sharp, black ring.  Too close, and you get blackouts.  Too far back, and you get an indistinct field edge.

Now, compare the two images to see if the captured images show any difference in the size of the image circles.

The apparent field of view is generally totally independent of magnification factor due to telescope focal length or Barlowing effects.  This test will allow you to get an unbiased image to check that for yourself.
