Yeah. And it's a refractor. A 150mm refractor. So its light-gathering power is not great, it's much heavier than it needs to be, and that apochromatic triplet lens is gonna be much, much more expensive than a mirror that's twice as big.
This is a wealth signifier like a diamond-encrusted cell phone. It's not a serious astronomical instrument.
