I noticed this with my Skywatcher illuminated finder I got with my ed80.
My GSO finderscope for the dob doesn't do this (it's not illuminated and it's a straight through).
I found it annoying at first as I was never sure if the star had drifted or if I had put my eye in a different place while drift-aligning. I'm used to it now though and it's not a problem.
I looked at the rifle scopes on ebay but they were all 30mm or less. Wouldn't be ideal for finding those dimmer stars while hopping around.
