These have focusing on the straight and angled eyepieces so the straight can be used on its own.
funny...I have only ever used the straight. I just priced the angle adapter at $345 from my source and $302.99 from MidWayUSA. Gradient makes them. Maybe I will look through the straight a few more years
The correction would be nice though when using the mirror.
