6SE is 1500mm focal length.
Jupiter lets say 80x as a minimum so that is an 18mm eyepiece.
Saturn lets say 120x and that is 12.5mm
Mars is likely the problem as you need 200x and more for any real "detail". Usually somewhat blurred detail. But more then a uniform reddish disk. 200x is 7.5mm. If the 9mm is considered too much then questionable.
The obvious at the 12 and 18 are the Paradigms. And simple answer is start with the 12mm, if that works and shows Saturn then use it on Jupiter. Maybe forget the 18mm then although likely useful.
Others - ES52, but the focal lengths don't fall as good. Guess the 10mm is the one but could be pushing your luck, would deliver 150x. The longer one is then the 15mm for 100x. Likely good ofr Jupiter, maybe bit small for Saturn.
11mm and 15mm TV plossl ? 136x and 100x.
ES68's in 16mm for 93x and the ES82 in 11mm for 136x .
Still excludes Mars - do you want much of/from Mars?
Thought was 11mm ES82 for Saturn and therefore Jupiter and say a risky 6.7mm ES82 for 223x and Mars. Risky as reads the scope is not delivering past the 9mm and 6.7mm is a big jump. Maybe forget.
Could you borrow an 8mm Paradigm? Or an 8mm TV plossl ?
Equally 8mm is just 187x, and Mars often requires more.
Hyperons I know nothing about, always had an odd reputation here.
General concern for planetary eyepieces is that you can have steps of 1mm between the shorter 8 eyepieces - Guess how I know
Add a location, doubt it but if sort of just up the road from me I have a number of eyepiece you could try.
And someone else did say "Whats the chance of that then?".
They lived 15 miles North of the club, I was 15 miles South and we were in the same club.
