Hi Bert

Here is a Sky & Telescope article where the author writes:

“In my 12.5-inch, I really can't see the difference between the 180x view in a 10.5-mm eyepiece and the 180x view in a 26-mm eyepiece of the same design with a 2.5x Barlow — except that the latter gives more comfortable eye relief.”

Cheers
