Hi,
I have a Tak 1.25 prism diagonal and a standard TV 1.25 diagonal. While not an exact match to your question the info may be helpful. I have used both and compared them both on two scopes, an FS102 and a 7" Meade Mak. I have swapped them out back to back and used the same eyepieces. Overall the Tak diagonal is brighter but if I get my eye off axis there is false color. If find my TV provides more contrast and is not as sensitive to the placement of my eye in relation to the optical path. After trying each for a while I have settled on using the TV diagonal.
Good luck,
Paul G.
