From what I have read and understand both the Attack and Observation periscope are both 1.5X and 6X magnification in low and high range respectively.
You may ask then why both scopes?
Well the following comes to mind:
#1 Obs scope has less optics- In reality I dont think it is kitted with a stadimeter.
#2 Its a backup should the optics go in the main scope due to pressure via normal operations or depth charges.
#3 It has larger ojective lense and optics - just like a telescope it will gather more light and resolve smaller/fainter objects better IE: Stars and planes.
#4 It has a greater vertical range of movement.
#5 Downside is that for all its advantages the Obsevation scope is easier to spot when in use than the attack periscope.
