I has the same 'focuser' from Starlight, but the PII.
-All insights is good insights.
I had a longer thread that actually got stopped on my question as some say the PII had a advantage over the Sips ( optically wise )
But in reality it’s the same lens system.
Why I got the indicate that the PII was 'better' - was never cleared out here.
Some like the PII for a easy slip in and use, and some just love the Sips as one adjust direct focus by adjust the focuser to each EP.
Some say the Sips will dew more easy and the deal to aply it in vs drop it of greasy fingers.
I kept my PII as the only disadvantage I see is the bad rolled top design, but if one accept the huge sag ( run-out from centre ) it is rather simple to use.
But both this system will be long & tall and very heavy in end.
Allof of weight is at end of the PII thread and that deal is really losy.
Asa full adopted PII can be from mirrors edge and out near half a meter long ,-)"
