a while ago I've made a post about my intention to buy a second hand GT81 Type II from a shop. I received the scope, it had mechanical problem with the focuser so I returned it. I found an agreement with the shop to get a new William Optics GT81 Type III plus a flattener 6A III by paying a little extra and I had to wait for its delivery from William Optics.
The shop received the scope but I still have to wait for the flattener to arrive. The shop's owner wrote me that he thinks it's a new version because the box states GT81 IV and that he doesn't know what the improvements are compared to the type III. I tried to look on google but I couldn't find any information.
At this point I am wondering if there's a type IV flattener too.
Sorry for the lack of extra information but this is all I got at the moment and I will not be able to see the scope for another couple of weeks or even more. Also the shop doesn't want to open the box because I want it untouched from WO to my home
Does anyone know anything about this?
