Can I use the Kowa TE-80XW for digiscoping?

Will the Kowa TE-80XW fit my TSN-82SV spotting scope?
Kowa lists the TE-80XW only for the TSN-99, TSN-88, TSN-77 and TSN-66 series. For the TSN-82SV, Kowa lists the TE-9Z, TE-14WD and TE-17HD eyepieces.

The TSN-99, TSN-88 and TSN-66 bodies have an eyepiece release button used to remove the eyepiece. Kowa's material gives no step by step procedure for this eyepiece, so follow your scope's instruction manual.
What is the difference between the TE-80XW and a zoom eyepiece like the TE-11WZ II?
A fixed eyepiece gives one magnification. Kowa's figures show the TE-80XW's field is wider than the TE-11WZ II zoom's widest setting on the same body (147.6 ft at 35x against 138 ft at 25x, at 1,000 yds on TSN-88/66), and Kowa says it gives vignette-free digiscoping images. A zoom lets you change magnification without swapping eyepieces.
What does the "XD Lens" in the Kowa TE-80XW eyepiece do?
XD refers to extra-low dispersion glass, which reduces chromatic aberration (color fringing). Kowa says the TE-80XW's XD and field flattener lenses deliver true color, sharp images and a wide field.
How should I use the twist-up eyecup on the TE-80XW?
Twist the eyecup up or down to set your eye at the distance where you see the full field. Kowa describes the eyepiece as having generous eye relief (17 mm) via the twist-up eyecup and gives no further eyecup instructions.
