I am selling my APO refractor bought at Teleskop Service in August 2019.
It is a 5-element flatfield APO with the corrector integrated before the focuser, meaning you don’t have to care about the backfocus. You just need to focus and that’s it!
The refractor is in very good condition. Pictures can be sent by request.
The refractor comes with a transport case that I bought separately.
