There is hot debate on this happening over on CN, which has even seen a thread locked. tl;dr: the Starbase is sold in some places, but not made, by Takahashi, and the same might apply to these eyepieces. User reports suggest this equipment is of solid quality if a bit costly, and, arguably, dated.
yes being sold in the tak walk in starbase store to get people into astronomy, as an introduction but not a takahashi branded product, apparently japan made so should be of decent quality
i wouldn’t mind the altaz mount, -pity not avail separately
