QHYCCD PoleMaster AstroTrac 導星支架轉接器 - PM-ASTROTRAC

The adapter slots onto my AstroTrac mount with a snug, precise fit — zero play once tightened, which is exactly what you want for polar alignment. Setup took me under five minutes and now the PoleMaster sits rock-solid for guiding sessions.

Snapped right onto my AstroTrac mount with zero wobble, and the PoleMaster lined up perfectly on the first try. Machined threads feel solid, not the cheap stuff I've dealt with before. Polar alignment went from a 20-minute hassle to about two minutes.

Wasn't sure the PoleMaster would sit flush on my AstroTrac, but this adapter lined up perfectly and the whole assembly feels rock solid. Polar alignment used to eat twenty minutes of my session — now it's done before my eyes even adjust to the dark.
