I had a look a few times in a AP130 f6.3 EDF and in fluorite (Vixen FS102), Zeiss A 130f18.(semi-apo), SkyW 120ED, Tak FS102, Altaïr 130f7 EDT.
Eyepiece suffers in the f/6-f/7 refractors, you need to put more money in. Radians vs Pentax VW and Nikon Nav-SW was the winner.
The Tak & Vixen accept modern orthos, but not well the oldest versions.
Zeiss A which is not apo gave the better rendering with his native Abbe Orthos.
Jupiter is the most difficult target for non apo, Altaïr and AP works well on it, giving colorless image.
But for sharpness inside BES and GTR, fluorite and semi-apo are at level or beyond : longer focal length help on tuning focus on the right color : you cannot do that on a locked focus apo, all blur simultaneously.
It is subtle at f/8 but very easy at f/18.
For strict visual and a perfect clean image, I recommend a bit longer f/D than f/6, which is more suited for photography.
The 130f/9 LZOS is a better choice in my opinion, with Vixen SLV maybe HR or Tak TOE for planetary and pentax XW for DSO
