I bought 2x 2" EP's with my GS dob, (as well as the 4 "bundled" series 500 plossls). On the box they are marked as GSO SP26mm and GSO SP32mm. The lettering on the EP's themselves only identify them as 26 & 32mm Fully Multi-Coated, but there are no letters indicating what type of EP they are.
Even my old Tasco's had a K, indicating they were Kelners. I was wondering (an idle mind under cloudy skies
) what these 2" are. Does the SP represent anything? Deep diving through google has taught me a lot more than I previously knew about EP's but has provided no enlightenment about these.
Can anyone tell me the type of construction of this EP? Do they have an inbuild barlow (I don't have a 2" barlow yet)?
